HD65 & HD130 STEPPER DRIVES USER GUIDE 1

Introduction

Product

Description The HD65 and HD130 stepper drives are bipolar, chopper-regulated
units designed to operate with a wide range of motors. They
incorporate all power supply components for direct operation from a
mains transformer. The two drives deliver nominal motor currents of
6.5A and 13A respectively, and both operate at a motor supply of
240V DC.
All translation and current control functions are performed by a ULA-
hybrid translator, and this incorporates a number of useful features
including an anti-resonance circuit and automatic current square-off.
The drives can be fitted with the optional MS20 microstep card which
gives 1000 or 2000 steps/rev from a standard 200-step motor.
