Product Details

1. Product Overview

The Yaskawa Serial Converter Unit JZDP-H005-250 is a peripheral device for Yaskawa Sigma-7 series linear servomotor systems, used to convert analog sine/cosine signals output by external RENISHAW linear scales/encoders into serial digital signals recognizable by Yaskawa servo drives (SERVOPACK), enabling high-precision position feedback and closed-loop control for linear servomotors.

This serial converter unit belongs to the JZDP-H series, featuring signal amplitude alarm function and thermal protection function, with signal resolution of 1/256 pitch (1/256 of one cycle of the input two-phase sine wave), maximum response frequency 250kHz, meeting the position feedback requirements in high-speed linear motion applications. The unit model code 005 indicates compatibility with encoders manufactured by RENISHAW, and no Hall sensor input; the suffix 250 indicates compatibility with a specific specification of linear servomotor.

In linear servomotor systems, the linear scale/encoder is usually installed near the motor, outputting analog sine/cosine (sin/cos) signals and reference (Ref) signals. These analog signals need to be interpolated, A/D converted, and serially encoded by the serial converter unit before being transmitted to the servo drive for position closed-loop control. The JZDP-H005-250 is the key device performing this signal conversion function, converting the analog differential signals of the RENISHAW encoder into standard serial differential signals for Yaskawa servo drives, connected to the encoder interface of the servo drive via a dedicated cable.

This unit adopts a balanced differential output circuit (SN75LBC176 or equivalent), with a built-in 120Ω terminating resistor, providing strong anti-interference capability, suitable for stable transmission of high-speed serial data in complex electromagnetic environments on industrial sites. The input side supports differential sine/cosine signals with input amplitude range 0.4V to 1.2V, and reference signal input level 1.5V to 3.5V. The unit is powered by the servo drive, with typical current consumption of 120mA and maximum 350mA.

The JZDP-H005-250 is equipped with a signal amplitude alarm function. When the encoder input signal amplitude is too low (possibly caused by encoder contamination, excessive installation gap, cable failure, etc.), the unit outputs an alarm signal, reminding maintenance personnel to check the encoder status in time, avoiding reduced control accuracy or operational faults caused by degraded position feedback signal quality. It is also equipped with thermal protection function, activating protection when the internal temperature of the unit is too high, ensuring safe and reliable operation.

This serial converter unit is compact and lightweight, convenient for installation near the linear motor or in the control cabinet. The connection cable between the serial converter unit and the servo drive must be prepared by the customer. The product is RoHS compliant (all H/J series models are RoHS compliant without the -E suffix).

Note: The model definition of this product JZDP-H005-250 is based on Yaskawa official nomenclature document (No. 900-289-836), and electrical parameters are based on Yaskawa Sigma series user manuals. Installation and wiring must be performed by professional engineers qualified in servo system commissioning, strictly following Yaskawa servo system installation and wiring specifications. The connection cable between the serial converter unit and the servo drive must be prepared by the customer; cable specifications please refer to the Yaskawa user manual.

Q3: What is the function of a serial converter unit? Why is it needed?

A: The Serial Converter Unit is a key signal conversion device in linear servomotor systems. Its main functions and necessity are as follows:

Functions:

Signal conversion: Converts analog sine/cosine (sin/cos) signals and reference (Ref) signals output by external linear scales/encoders through interpolation, A/D conversion, and serial encoding, into high-speed serial digital signals recognizable by Yaskawa servo drives.
Position feedback: Transmits real-time position information of the linear motor to the servo drive in serial data format, enabling high-precision position closed-loop control.
Signal processing: Amplifies, filters, and interpolates encoder analog signals, improving position feedback resolution and accuracy.
Alarm monitoring: Type H/J units have signal amplitude alarm function, real-time monitoring of encoder input signal quality, outputting an alarm when signal amplitude is too low, reminding maintenance personnel to check encoder status.
Thermal protection: Type H/J units have thermal protection function, activating protection when internal temperature is too high, ensuring device safety.

Why a serial converter unit is needed:

Signal format mismatch: External linear scales (such as RENISHAW, HEIDENHAIN) usually output analog sine/cosine signals (1Vp-p differential), while Yaskawa servo drive encoder interfaces receive serial digital signals. The two formats do not match, and format conversion must be performed through a serial converter unit.
Improve resolution: One cycle of the analog sine signal of a linear scale corresponds to one pitch (such as 20μm, 40μm), and direct use has lower resolution. The serial converter unit improves position feedback resolution by interpolation (e.g., 1/256 pitch), subdividing one cycle into 256 parts.
Long-distance transmission: Analog signals are susceptible to interference and attenuation during long-distance transmission, while serial differential signals have stronger anti-interference capability, suitable for longer distance transmission from the motor end to the control cabinet.
System compatibility: Yaskawa servo drives are designed to receive serial encoder signals. The serial converter unit enables third-party linear scales (RENISHAW, HEIDENHAIN, etc.) to be compatible with Yaskawa servo systems.
