EM Series Drive Hardware Installation Manual

HWMN-EM-R20111018

9. Wiring Notes

In order to improve anti-interference performance of the drive, it is recommended to use twisted pair shield cable.

To prevent noise incurred in PUL/DIR signal, pulse/direction signal wires and motor wires should not be tied up together. It is

better to separate them by at least 10 cm, otherwise the disturbing signals generated by motor will easily disturb pulse direction

signals, causing motor position error, system instability and other failures.

If a power supply serves several drives, separately connecting the drives is recommended instead of daisy-chaining.

It is prohibited to pull and plug power connector while the drive is powered ON, because there is high current flowing through

motor coils (even when motor is at standstill). Pulling or plugging power connector with power on will cause extremely high

back-EMF voltage surge, which may damage the drive.

10. Configuring the Drive

Introduction

The EM drive uses DIP switch and rotation switch to select dynamic current, idle current and motor. When the DIP switch is in software

configured mode, microstep resolution and output current are programmable and set via the RS232 communication port. Refer to the

EM drive’s software operational manual for more information.
