*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 operation during output suspension can be selected for the integral term using the PID output suspension
(sleep) function.
• The manipulation range can be selected.

12 Integral stop
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 reaches plus or minus 100% (Pr.1015 = "0 or 10").
• The manipulated amount reaches 0% or 100% (Pr.1015 = "2 or 12").
 PID monitor function
• This function displays the PID control set point, measured value and deviation on the operation panel, and can output these
from the terminals FM/CA and AM.
• An integral value indicating a negative % can be displayed on the deviation monitor. 0% is displayed as 1000. (These
values cannot be output on the deviation monitor from terminals FM and CA.)
