AC100 HIGH-PERFORMANCE VC INVERTER MANUAL
For example: Under pressure control, when it is set as sensor max measuring range, it displays actual pressure.
If VS is feedback signal input channel, when VS highest limit is set as 9V and lower limit 0.5V, feedback voltage is 4.5V,
and sensor measuring range is 20mpa.

PID control selections
LED "0" digit: feedback feature selection
0: Positive feature: suitable for occasions where PID feedback is bigger than PID given and requires output frequency
reducing to balance PID. Such as constant pressure water supply, gas supply, take-up tension control.
1: Negative feature: suitable for occasions where PID feedback is bigger than PID given and requires output frequency
rising to balance PID. Such as constant temperature control, pay-off tension control.
LED "00" digit: PID adjustment direction selection
0: REV forbid
1: REV permit
Inverter control output frequency after given signal and feedback signal calculation according to PID control mode
setting when receiving the run order. If REV forbid ([F0.07] LED "00"digit is 0 frequency control direction invalid or
[F0.16] is 2 REV forbid), inverter outputs 0.00Hz. If REV permit, inverter will change output direction, motor REV.
LED "000" digit: align selection
When PID setting is not at the centre point of 50%, error range of PID feedback and PID setting is non-symmetry state.
0: Not centre align：No correcting error.
1: Centre align：Correcting error

PID preset frequency running time
When it defines as PID start running, frequency ACC to PID pre-set frequency [Fb.06] according to ACC time 1. After
setting [Fb.07] time, it runs as PID closed loop trait.
