Manual detection of the home position
Input the all windings off signal, set the motor to the desired position, then release the all
windings off signal.
The number within refers to the pin
number of driver connector SIGNAL 1.
Keep the voltage between DC5V and DC24V.
When voltage is equal to DC5V, external
resistance R is not necessary.
When voltage is above DC5V, connect
external resistance R, and keep the input
current below 20mA.
Half Step
Standard type:
When the step angle signal is in the
“photocoupler ON” state, it is set to half-step
mode (0.36°/step, 1 rotation 1000 pulses)
Geared type:
When the step angle signal is in the
“photocoupler ON” state, it is set to half-step
mode
(0.36°× / step,
1 rotation 1000×gear ratio pulses)
Full Step
Standard type:
When the step angle signal is in the
“photocoupler OFF” state, it is set to full-
step mode (0.72°/step, 1 rotation 500
pulses)
Geared type:
When the step angle signal is in the
“photocoupler OFF” state, it is set to full-
step mode
(0.72°× / step,
1 rotation 500×gear ratio pulses)
Note
When the step angle signal is used, the switch must be set to the F position.

Note
For geared type, do not do manual detection of the home position. It may cause damage
the gearhead and may cause the following problems.
• The motor makes a strange noise.
• The motor does not rotates correctly.
