b74 PID update time (s) : 00.0 - 02.5
b74: the refresh time of PID output command.
Note: PID function is used in flow control, fan air volume control and temperature control.

Select
1. In PID mode, select AIN on TM2 as PID feedback signal, Set b41 = 018.
2. The PID set-point control input is set by parameter A01 (selections 000 & 001).
This value is stored in b45.
b75 PID Sleep frequency (Hz) 00.0~200Hz
b76 PID Sleep delay time (sec) 00.0~25.5sec
PID sleep mode can be set by using function codes below: -
b67 = 001~004 (PID Enable)
b41 = 018 (AIN is PID feedback signal)
b45 = PID preset frequency
b75 = sleep start frequency, (Hz)
b76 = PID sleep delay time, (s)
When PID output frequency becomes lower than PID sleep start frequency (b75) for
a period of time (b76), the iDrive output will decelerate to zero speed (Sleep mode). When the PID
output frequency becomes higher than the sleep start frequency (b75), the iDrive output accelerates
to PID output frequency (Wake-up mode).
