P50.18 PID differential limit
Sets differential output limit of PID control.
P50.19 PID initial value
Holding time of PID initial
P50.20
PID does not make adjustment when the drive starts its running, but outputs the value set by
P50.19 and maintains the holding time set by P50.20, then starts PID adjustment. When
P50.20 is set to 0, PID initial value is disabled. This function makes PID adjustment get into
stable status fast.
PID feedback loss
P50.21
detection value
PID feedback loss
P50.22
detection time
When offset between feedback and setting of PID is bigger than set value of P50.21 and the
lasting time attains the set time of P50.22, the drive reports fault "Plo". If P50.22 is set to 0,
feedback loss detection is disabled.
Maximum
P50.23
opposite to command direction
When run command direction is forward, while PID output is reverse, the maximum reverse
frequency will be determined by P50.23.
When run command direction is reverse, while PID output is forward, the maximum
forward frequency will be determined by P50.23.
P50.24 PID computation option
0: No computation in stop status
1: Computation continued in stop status
