INSTRUCTION MANUAL FOR RD-023MS

１．Description

Custom LSI and hybrid circuitry makes this driver ultracompact and power efficient. Therefore, by

utilizing a DC power supply of 24V or 36V (as is common to solenoid valves, etc.), several units can

be connected to a simple programmable controller or personal computer with great economy of

wiring.

The RD-023MS is a high resolution stepping motor driver featuring selectable microstep.

Microstep drive is the drive method to resolve a basic step angle of motor by controlling the current

applying to the motor. The user can select from 1 to 400 microsteps/step.

Steps for 1.8ﾟ motor in full step mode is 200 steps/revolution (1.8ﾟ/pulse), but if you select 400

microsteps/step in microstep mode, it can be 80,000 steps/revolution (0.0045 ﾟ /pulse).

Microstepping can provide low speed drive and accurate positioning.

Also, a significant weakness of full step driving is the vibration and resonance but microstepping can

reduce amplitude of resonance. 2-phase motor will produce vibration than 5-phase motor in half

step mode.
