 PID control during emergency drive operation
• The Pr.524 setting is used as a set point for operation during emergency drive operation in the PID control mode. Input
the measured values in the method set in Pr.128 or Pr.753.
• When the PID control mode is selected for emergency drive, the PID action during emergency drive operation is as follows
depending on the PID control setting.

Measured value input selection
(Pr.128 and Pr.753)
Forward action / reverse action
selection (Pr.128 and Pr.753)
Proportional band (Pr.129 and
Pr.756)
Integral time (Pr.130 and Pr.757) Held
Differential time (Pr.134 and
Pr.758)
Applied to the frequency /
calculation only (Pr.128 and
Pr.753)
Other PID-related settings
• While the "retry" (Pr.523 = "22[], 32[]") is selected in the PID control mode, if a retry occurs at an occurrence of E.CPU,
E.1 to E.3, or E.5 to E.7 during emergency drive operation, the operation is performed not under PID control but with the
fixed frequency.
Use Pr.1013 Running speed after emergency drive retry reset to set the fixed frequency.
NOTE
• Refer to
 Operation of protective functions during emergency drive
• Operation of protective functions during emergency drive is as follows.

*1 While the switchover to the commercial power supply operation during emergency drive operation is enabled, when the same protective function
is activated twice consecutively, the retry is attempted up to twice.
*2 In normal operation (Pr.523 = "200 or 300"), the start signal is turned OFF at the same time the retry function resets the protective function. Input
the start signal again to resume the operation.
