Motor direction of rotation
With parameter p29001, you can reverse the direction of rotation of the motor without
changing the polarity of pulse train input setpoint and analog input setpoint. The polarity of
output signals like pulse train encoder output (PTO) and analog monitoring remains
unchanged at a reversal of direction.
