Refer to figure 4.3.83 (a), (b) and (c) for PID sleep/wakeup operation:

10-40=0, refer to Figure 4.3.83(b)
The PID sleep timer is enabled when the output frequency (Fout) falls below the PID sleep frequency
(10-17). When the sleep timer reaches the set PID sleep delay time (10-18) the inverter will
decelerate to a stop and enter the sleep mode.
10-40=1, refer to Figure 4.3.83(c)
When output frequency (Fout) is lower than PID sleep frequency set by 10-17, Timer of PID sleep
mode will run and the output frequency changes with the reference frequency (Fref) until it reaches
the minimum output frequency (Fmin) set by 01-08. When the PID sleep delay time (10-18) is
completed, the motor will run gradually to the PID sleep frequency set by 10-17.
