• For the terminal used for the SLEEP signal, set "70" (positive logic) or "170" (negative logic) in any parameter from Pr.190
to Pr.196 (Output terminal function selection).

*1 When the PID output shutoff release level is reached during a deceleration stop, output shutoff is released, operation is re-accelerated and PID
control is continued. During deceleration, Pr.576 Output interruption detection level is invalid.
 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 manipulation range can be selected.

*1 When the frequency reaches the upper limit, or when the PID manipulated amount reaches 100%, the integral stops and the integral term is
retained. When the frequency decreases, the integral does not stop until the manipulated amount reaches -100%, regardless of the output
frequency.
