0: PID output is positive: when the
feedback signal exceeds the PID
reference value, the output frequency of
the inverter will decrease to balance the
PID. For example, the strain PID control
during wrapup
1: PID output is negative: When the
feedback signal is stronger than the PID
reference value, the output frequency of
the inverter will increase to balance the
PID. For example, the strain PID control
during wrapdown
