. Based on the energy demand, the PID sleep / waking up function allows the motor
automatically starts / stops.
. Refer to the following figure 4.3.83 for PID sleep / waking up operation.
(a) PID control bock diagram
(b) timing diagram of PID sleep／waking up
Figure 4.2.83 PID sleep／waking up operation
. When the output frequency (Fout) is lower than the PID sleep frequency set by
10-17, the timer of PID sleep mode will be enabled, and the output frequency will
change according to the reference frequency (Fref) until the minimum output
frequency (Fmin) set by 01-08 (Fmin) is reached. When 10-18 (delay time of PID
sleep) is reached, the motor of inverter will gradually decelerate to stop and the
inverter enter the sleep mode.
. When the inverter enters a sleep mode and the motor stops operation, the PID
control is still in operation. When the reference frequency increases and exceeds
the waking up frequency set by 10-19, and the delay time set by 10-20 is reached,
the motor of inverter will restart and the output frequency will climb to the reference
frequency.
. 10 - 00 and 10--01 can not be set to the same source. If they are set to the same
values, the panel will display the PID selection’s error message of "SE05".
