Instructions Manual

２．Overview

２－１．Characteristics

GDB-5K20 is a driver for a 5-phase stepping motor with DC +24V input.
It can drive a 5-phase stepping motor with 0.35A/phase.
Step angles can be selected from eighteen step angles ranging from 1 division to
8000 division of the basic angle.
HOLD CURRENT and DRIVE CURRENT can be set up.

● Applicable motors and setting for each motor are given in the table

 "10-4. Applicable Motors".

２－２．Product Configuration
