Function explanation（Stepping motor control）

1. CLK Function

The CLK pin controls the rotation speed of the motor. Each CLK signal will shift the

motor’s electrical angle per step, due to each up-edge of the CLK signal.

CLK Input

Up-edge

Function

Shifts the electrical angle per step.

(State of the electrical angle does not change.)

Down-edge

2. ENABLE function

The ENABLE pin controls the ON and OFF of the corresponding output stage. (For

accurate operation, please set the ENABLE pin to ‘L’ during VM power-on and

power-off sequence.

ENABLE Input

Function

Output stage=‘ON’ (Normal operation mode)

Output stage=’OFF’ (High impedance mode)

3. CW/CCW function

The CW/CCW pin controls the rotation direction of the motor.

CW/CCW Input

Function

Clockwise rotation

Counter clockwise rotation

4. Step resolution select function

The D_MODE pin controls the Standy mode and the step resolution setting.

D_MODE_1

D_MODE_2

Function

Standby mode (the internal oscillator is disabled and the output

stage is set to ‘OFF’ status)

Full step operation

Half step operation

Quarter step operation

5. RESET function

The RESET pin controls the resetting of the electrical angle. (For accurate operation,

please set the RESET pin to ‘H’ during power-on. Switch the RESET to ‘L’ once the

VM voltage has reached the operation level.)

RESET Input

Function

Normal operation mode

Sets the electrical angle to the initial condition.

The current setting for each channel (while RESET is applied) is shown in the table

below. MO_OUT pin level will show ‘L’ at this time.

Step resolution setting

Full step

Ach current setting

100%

Bch current setting

100%

71%

100%

71%

Half step

Quarter step
