C37 PID postpone time (s): 00.0 - 02.5
C37: the refresh time of PID output command.
※
Note: PID function is used in flow control, external fan wind volume control and
temperature control. And the control flow is as the following figure:
1. In PID mode select, AIN on TM2 as PID feedback signal, Set F15=018.
2. The PID command ( Target value) is selected by parameter F05 ( selections 000 & 001).
This value is stored in F28.
PID sleep mode must set below function ：
C30=001~004(PID Enable)
F15=018(AIN is PID feedback signal)
F28=PID preset frequency
C38 sleep start frequency, unit: Hz
C39 PID sleep delay time, unit: Sec
When PID output frequency becomes lower than PID sleep start frequency (C38) for
a period of time (C39),then the inverter output will decelerate to zero speed(Sleep mode).
When the PID output frequency becomes higher than the sleep start frequency (C38), the
inverter output accelerates to PID output frequency ( Wake up mode).
.
C38 PID Sleep start frequency (Hz) 00.0~200Hz
C39 PID Sleep delay time (sec) 00.0~25.5sec
