Product Details

1. Product Overview

The ABB NTAC-02 (order number 58976008) is a Pulse Encoder Interface Module manufactured by ABB Drives, specifically designed for ABB ACS600 and ACS800 series industrial drives. It is used to connect incremental pulse encoder speed and position feedback signals to the drive, enabling high-precision closed-loop speed control and position control, widely used in industrial applications requiring precise speed regulation, positioning, and synchronization control.

In industrial drive applications, when precise speed or position (angle) feedback from the motor shaft is required, a pulse encoder must be used. The pulse encoder is mounted on the motor shaft and outputs A-phase, B-phase quadrature pulse signals and Z-phase zero pulse signals as the motor rotates. The NTAC-02 pulse encoder interface module serves as a bridge between the encoder and the drive, receiving the pulse signals output by the encoder, performing signal conditioning, electrical isolation, and counting processing, then transmitting speed and position data to the drive main control unit via the drive internal bus. This enables the drive to implement advanced control functions such as closed-loop vector control, Direct Torque Control (DTC), speed closed-loop regulation, position positioning control, and multi-axis synchronization control.

The NTAC-02 supports incremental pulse encoder input, including A-phase, B-phase quadrature pulse signals, and optional Z-phase (zero/index) pulse signals. The A/B-phase quadrature signals can determine rotation direction (forward/reverse) through phase difference, calculate rotation angle and position through pulse counting, and calculate rotation speed through pulse frequency. The Z-phase zero pulse outputs one pulse per revolution for position homing and reference point positioning. The maximum input signal frequency is as high as 100 kHz, meeting the precise speed feedback requirements of high-speed rotating motors, providing sufficient pulse resolution and response speed even at the motor's maximum speed.

In terms of signal levels, the NTAC-02 supports HTL (Push-Pull) and TTL level encoder signal inputs. The HTL level signal high-level threshold is greater than 7.6V, and the low-level threshold is less than the specified value (specific subject to official manual), with strong anti-interference capability and long transmission distance, suitable for long-distance encoder signal transmission in industrial fields. TTL level signals are suitable for short-distance, high-rate signal transmission. The module has built-in signal conditioning and shaping circuits that can filter, shape, and level-convert encoder input signals, ensuring stable and reliable reception of encoder signals in complex industrial electromagnetic environments.

The NTAC-02 provides encoder power supply output, with 15V or 24V DC voltage selectable via jumper to power the external encoder, eliminating the need for an additional encoder power supply and simplifying system wiring and configuration. The encoder power output has short-circuit protection and overcurrent protection to prevent module damage caused by encoder wiring short circuits or faults. The module itself uses 24V DC industrial standard power supply (voltage range 24V DC ±10%), with power consumption of approximately 7.5W (300mA), and can be directly powered by the drive internal or external 24V DC control power supply.

In terms of electrical isolation, the NTAC-02 provides electrical isolation between the encoder input signals and the drive internal control circuit, effectively protecting the drive's sensitive control electronics from electrical noise, common-mode voltages, and transient overvoltages generated by the motor and encoder cables, while reducing ground loop interference and improving system anti-interference capability and operational reliability. Electrical isolation is an important safety feature for industrial encoder interfaces, especially in high-power drive applications where high shaft voltages may be induced on the motor shaft and coupled through encoder cables to the encoder and interface circuits. Electrical isolation can effectively block this coupling.

The NTAC-02 features a plug-in/rail-mount module design, installed in the drive's option slot or on a DIN rail in the control cabinet (specific mounting method subject to official manual), communicating with the drive main control unit via the drive internal bus or dedicated connector. The module has compact dimensions (approximately 108mm × 75mm × 45mm, net weight approximately 0.5kg), saving installation space. Onboard status indicators can display power status, encoder signal status, and fault status, facilitating field maintenance personnel to quickly assess module operating status and encoder connection status. Made in Finland, manufactured by ABB's Finnish factory with reliable quality.

This module is widely used in the following industrial applications requiring precise speed and position feedback: metallurgical rolling mill main and auxiliary drives, paper machinery drive systems, printing machinery registration control, textile machinery synchronous drives, machine tool spindle and feed axis control, crane and hoist speed control, test stand dynamometer systems, elevator and escalator control, packaging machinery positioning control, food and beverage machinery drives, etc. In these applications, the NTAC-02 ensures the drive can obtain precise motor speed and position feedback, achieving high-precision closed-loop control to meet strict production process requirements for speed accuracy, positioning accuracy, and synchronization accuracy.

Note: This product NTAC-02 (58976008) is a pulse encoder interface option module for ABB ACS600/ACS800 series drives, and must be used with the corresponding drive model.

User must supply incremental pulse encoder and encoder cable separately. Installation and wiring must be performed by professional engineers with electrical operation qualifications.

Q2: What types of encoders does NTAC-02 support? How to select an encoder?

A: The NTAC-02 supports incremental pulse encoders, with specific requirements as follows:

Supported encoder types:

  1. Output signals: A-phase, B-phase quadrature pulse signals, optional Z-phase (zero/index) pulse signal
    • A and B phases with 90° phase difference (quadrature), used for rotation direction detection and counting
    • Z-phase outputs one pulse per revolution, used for position homing and reference point positioning
  2. Signal levels:
    • HTL (Push-Pull): High level typically 10-30V, strong anti-interference, long transmission distance, suitable for long-distance transmission in industrial fields
    • TTL (RS-422 differential): High level typically 5V, high transmission rate, suitable for short-distance high-speed transmission
    • NTAC-02 HTL input high-level threshold >7.6V, specific low-level threshold subject to official manual
  3. Max. pulse frequency: ≤ 100 kHz (NTAC-02 maximum input signal frequency)
  4. Supply voltage: Encoder power supplied by NTAC-02, jumper selectable 15V DC or 24V DC
    • When selecting 15V supply, use 15V-powered encoder
    • When selecting 24V supply, use 24V-powered encoder
    • Can also use external independent power supply for encoder (note common ground and signal level matching)

How to select an encoder:

  1. Determine pulse count (PPR):
    • Select encoder pulse count based on speed control accuracy and position control accuracy requirements
    • Common pulse counts: 100, 250, 500, 600, 1000, 1024, 2000, 2048, 2500, 5000 PPR (pulses per revolution)
    • Higher pulse count = higher speed and position feedback accuracy, but higher pulse frequency at same speed
    • Must ensure pulse frequency at motor maximum speed does not exceed NTAC-02 100kHz limit
    • Calculation formula: Max pulse frequency = (motor max speed RPM ÷ 60) × pulse count PPR
  2. Determine signal level type:
    • Long-distance transmission (>10m), strong EMI environment → select HTL push-pull output encoder
    • Short-distance transmission (<5m), high-rate application → select TTL/RS-422 differential output encoder
    • Note NTAC-02 input level thresholds, ensure encoder output level matches
  3. Determine supply voltage:
    • Select encoder with corresponding supply voltage based on NTAC-02 encoder supply jumper setting (15V or 24V)
    • 24V-powered encoders commonly used in industrial fields, good compatibility
    • Some high-precision encoders use 5V supply, requiring external 5V power supply, cannot use NTAC-02 15V/24V output
  4. Determine mechanical mounting form:
    • Solid shaft encoder (requires coupling to connect to motor shaft)
    • Hollow shaft/blind hollow shaft encoder (directly mounted on motor shaft)
    • Through-hole shaft encoder (passes through motor shaft)
    • Select appropriate mounting form based on motor shaft diameter and installation space
  5. Determine protection degree and environmental adaptability:
    • Normal indoor environment → IP54/IP64
    • Humid, dusty, outdoor environment → IP65/IP67
    • High-temperature environment → select high-temperature resistant model
    • Strong vibration environment → select vibration-resistant model

Recommended encoder brands (reference):

  • Leine & Linde (Sweden, well-known industrial encoder brand)
  • Kübler (Germany)
  • Pepperl+Fuchs (P+F)
  • Siemens
  • Turck
  • ELCO
  • Other incremental encoders with HTL/TTL output, A/B/Z phases, 15V/24V supply

Q3: How to install and wire NTAC-02? What should be noted?

A: NTAC-02 installation and wiring must be performed by professional engineers with electrical operation qualifications, strictly following ABB drive installation manuals and electrical safety operation procedures. The following are general reference steps:

Pre-installation preparation:

  1. Confirm compatibility: Confirm NTAC-02 is compatible with your drive model (ACS600/ACS800), confirm drive firmware version supports encoder interface function
  2. Safety power-off: Disconnect drive main power and control power, wait for drive internal capacitors to fully discharge (wait at least 5 minutes, specific subject to discharge time specified in drive manual), confirm DC bus voltage has dropped to safe level
  3. Prepare tools: Prepare Phillips screwdriver, anti-static wrist strap, multimeter, wire stripper, crimping tool, etc.
  4. Prepare materials: NTAC-02 module, incremental encoder, shielded twisted pair encoder cable, cable glands, cable ties, etc.

Installation steps (reference):

  1. Power off and discharge: Disconnect all drive power supplies, wait for capacitor discharge, use multimeter to confirm DC bus voltage < 36V (safe voltage)
  2. Open drive cover: Loosen fixing screws of drive front cover/wiring compartment cover, remove cover
  3. Anti-static: Wear anti-static wrist strap and ground reliably to prevent electrostatic damage to module
  4. Install NTAC-02 module:
    • Locate option slot/connector position inside drive (specific location reference drive hardware manual)
    • Align NTAC-02 module with slot, insert smoothly, ensure connector fully engaged
    • Fix module to drive frame with fixing screws
  5. Set encoder supply jumper:
    • Based on encoder supply voltage requirement, set NTAC-02 supply jumper to 15V or 24V
    • Jumper setting location and method reference NTAC-02 installation manual
  6. Connect encoder cable:
    • Connect one end of encoder cable to encoder
    • Route the other end into drive wiring compartment, connect to NTAC-02 module encoder wiring terminals
    • Wiring definition reference NTAC-02 installation manual (usually includes: A+, A-, B+, B-, Z+, Z-, encoder supply+, encoder supply-, shield ground, etc.)
    • Ensure wiring is secure, no looseness
  7. Shield grounding:
    • Encoder cable shield should be single-end grounded at drive side (usually connected to drive ground terminal/shield grounding bar)
    • Encoder side shield treatment method reference encoder manual (usually not grounded or grounded through capacitor)
    • Avoid grounding shield at both ends to form ground loop
  8. Check and organize:
    • Check all wiring is correct, no short circuits, no looseness
    • Organize cables, secure with cable ties, avoid cables contacting hot components and moving parts
    • Confirm no tools, screws, or other foreign objects left inside drive
  9. Restore cover: Reinstall drive front cover/wiring compartment cover, tighten fixing screws
  10. Power-on test:
    • First turn on control power, observe NTAC-02 module status indicators
    • Power indicator should be steady on (green)
    • Encoder signal indicator should blink when motor rotates
    • Fault indicator should not be steady on
    • Then turn on main power, check encoder feedback speed and position via drive control panel

Wiring precautions:

  1. Cable selection: Must use shielded twisted pair cable, A-phase and B-phase should each use twisted pair, shield coverage recommended ≥ 85%. Cable length determined by signal level and environment, HTL signals typically up to 100-300m, TTL signals typically no more than 10-30m.
  2. Cable routing: Encoder cables should be routed separately from power cables (motor cables, drive output cables), minimum spacing recommended ≥ 20cm, avoid parallel routing. If crossing is necessary, cross perpendicularly. Encoder cables should not be in the same cable tray/trunking as power cables.
  3. Shield grounding: Shield single-end grounded (usually at drive side), avoid grounding at both ends to form ground loop. If large ground potential difference at site, consider using isolated encoder or signal isolator.
  4. Wiring terminals: Ensure all wiring terminals are tight, avoid loosening due to vibration. Stranded flexible wires should be crimped with ferrules (cord end terminals) before connecting to terminals.
  5. Encoder supply: Confirm encoder supply voltage (15V/24V) matches encoder rated voltage, jumper setting correct. Encoder supply circuit has short-circuit protection, but wiring short circuits should still be avoided.
  6. Signal level matching: Confirm encoder output level (HTL/TTL) matches NTAC-02 input level. If encoder output is 5V TTL and NTAC-02 input is HTL threshold, signal recognition may be abnormal, requiring signal conversion module or selecting appropriate encoder.
  7. A/B phase sequence: If after power-on the speed feedback direction is opposite (forward shows negative speed), swap A-phase and B-phase wiring, or set reverse direction via drive parameters.
  8. Z-phase connection: If zero positioning function not required, Z-phase can be left unconnected. If position homing function required, Z-phase must be connected and related parameters correctly set.

Specific installation location, wiring terminal definitions, jumper settings, parameter configuration, etc. are subject to ABB NTAC-02 installation and start-up guide and corresponding drive hardware manual. For installation guidance or technical support, Contact via email.
