Hi..

I have a Sensarc SP-500 Kobelco with Picomax-2 OH-AUTO control, one of my DC servo motor didn't work properly (travel motor), it seem's just spin in 1 direction (to the left), when I switch the control up and down it didn't respond at all.

I've measure the voltage, -40V (max input motor 23V), it seem's that the output from the control didn't change/reverse the current voltage that control DC servo motor.

I've try everything but still the same,

Did anyone have the solution?

Thank's
