Remedy, advice
ü Check the wiring.
ü Replace recommended encoder.
ü Set SWENC-2 " OFF" on the card.
ü Tune Kp and J parameters which are
related to ASR to reduce the speed
overshoot.
ü Increase position loop gain of APR.
ü Decrease the input pulses per second of
the pulse train input.
ü Make sure the connection of the board
