Positive Characteristic; Negative Characteristic - Veichi Electric AC60 series Manual

0：Positive characteristic
balance by reducing the frequency inverter output frequency while the PID
feedback quantity is greater than PID given quantity. Such as constant
pressure water supply, gas supply and take-up tension control.
1：Negative characteristic
balance by enhancing the frequency inverter output frequency while the PID
feedback quantity is greater than PID given quantity. Such as central
air-conditioning constant control and pay-off tension control.
While frequency inverter receiving the operation order, frequency inverter
will automatically control output frequency after calculation for the given
signal and feedback signal of the terminal according to the PID setting control
mode.
While the PID controls to cancel the terminal conncetion, frequency
inverter will convert the given signal to output frequency directly without
PID adjustment.
