PID control during emergency drive operation
• During emergency drive operation in the PID control mode, the operation is performed under PID control using
the
Pr.524
setting as a set point. 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.
• 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 Emergency drive running speed after retry reset
to set the fixed frequency.
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.
