gefran VDI100 Series

off when the PID output falls below the PID sleep level (10-17) for the time specied in the PID sleep delay time
parameter (10-18).
The inverter wakes up from a sleep condition when the PID output (Reference frequency) rises above the PID
wake-up frequency (10-19) for the time specied in the PID wake-up delay time (10-20).
10-29 =0: PID Sleep function is disabled.
10-29 =1: PID sleep operation is based on parameters of 10-17 and 10-18.
10-29 =2: PID sleep mode is enabled by multi-function digital input
Refer to the following gures for PID sleep / wakeup operation.
