I have a problem with my vexta stepper motor. Using the PIC16f877, I could run the motor. But using the keyence kv-40DR I am unable to do so. The motor moves forward and backwards, kind of weird movement.
The programming is almost the same. Same pulse inputs and etc. I have tried with different driver and even motor. But same results.
The only difference is the PIC16f877 is a transistor relay and the kv-40DR is a normal relay PLC.
Is that the cause of the problem?
