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.

２．Features

･RD-023MS carries out the CE Marking

･High power (3A/phase max.)

･Large supply voltage range (18 to 40VDC)

･Selectable microstep (22 selections) using dip switches

･Photo-isolated inputs and outputs

･Circuitry to protect against overheating, over current, and low supply voltage

･Selectable current range - 1.5A max. or 3A max.

･Selectable clock – 1clk. or 2clk. Input

･Auto current down circuit to reduce heat generation when motor is stationary

RD-023MS 3

５．Current Adjustment

Fig.2. Current Setting Trimmers

5-1 Run Current Adjustment Trimmer

Caution

Please use after adjusting the current within the motor rated current.

Exceeding the rated current causes the failure of motor or fire.

This is used to adjust the stepping motor drive current and in general it makes equal to the rated

current. (Setting at shipment is 0A.)

If a motor is used at a high rpm with a lower-than-rated torque, better efficiency and less

temperature rise can be obtained by using the motor with a current lower than the rated value.

(Note: As the current decreases, the torque will lower.)

The drive current changes relative to the dial. The value of the setting will be ±10 % of the set

value. (Use 1.5A setting when the motor rating is less than 1.5A. Set the amp. dip switch to 1.5A

side, because it makes current adjustment easier.)

Fig.3. Run Current Setting

5-2 Stop Current Adjustment Trimmer

This trimmer can adjust holding current when the motor is stationary. (Current after auto. current

down works.) You can set the stop current to any value between 0 and 80% of the run current by

adjusting Stop Current Adjustment Trimmer. (Setting at shipment is 50 %.)
