- Connect the controller connector.
Set the switch to "ON" with switch to "RUN" and
side stand raised. Repeat the "ON" "OFF" "ON"
switching.
Check the presence of voltage pulses on the
stepper command lines.
Setup for direct voltage measurements.
14-24 = V (pulses for a few seconds)
6-21 = V (pulses for a few seconds)
NOTE:
pulses are used to change the stepper
position.
A
fter reaching the optimum position, the power
supply voltage becomes null.
