NOTE
• The stirring function during the PID sleep prevents clogging of the pump while the sleep function is activated. (Refer to
page 440.)
• The PID sleep boost function maintains the sleep state for a long period of time. (Refer to
 Integral stop selection when the frequency is limited (Pr.1015)
• The operation for the integral term can be selected when the frequency or the manipulated amount is limited during PID
control. The operation during output suspension can be selected for the integral term using the PID output suspension
(sleep) function.
• The manipulation range can be selected.

NOTE
• While the integral stop is selected, the integral stop is enabled when any of the following conditions is met.
The frequency reaches the upper or lower limit.
The manipulated amount falls outside the range of ±100% (Pr.1015 = "0 or 10").
The manipulated amount falls outside the range from 0 to 100% (Pr.1015 = "2 or 12").
When a frequency set in Pr.576 Output interruption detection level is lower than the minimum frequency, the frequency command
value falls down to the level set in Pr.576 after PID calculation (when the PID output suspension function is enabled).
