Special operation and frequency control
(7) PID output suspension function (SLEEP function) (SLEEP signal,
Pr. 575 to Pr. 577
)
 The inverter stops operation if the output frequency after PID operation remains at less than the Pr. 576 Output interruption
detection level
setting for longer than the time set in
Pr. 575 Output interruption detection time
. This function can reduce
energy consumption in the low-efficiency, low-speed range.

When the deviation (= set value - measured value) reaches the PID output shutoff cancel level (
Pr. 577
setting -1000%)
while the PID output interruption function is ON, the PID output interruption function is canceled and PID control operation
is resumed automatically.
 While the PID output interruption function is ON, the PID output interruption signal (SLEEP) is output. At this time, the
inverter running signal (RUN) is OFF, and the PID control operating signal (PID) is ON.
 For the terminal used for the SLEEP signal output, assign the function by setting "70" (positive logic) or "170" (negative
logic) in Pr. 190 or Pr. 192 (output terminal function selection) .
* When the output rises to the output interruption cancel level during deceleration to a stop, output interruption gets cancelled, and the motor accelerates again
to continue PID control. Pr. 576 Output interruption detection level is invalid during deceleration.
