This parameter is effective only when the printed circuit board PG-B2 is used
Selects whether speed control (ASR) integral operation is activated during acceleration/deceleration.
Setting Range: 0 to 120%
Factory Default: 115%
Sets the motor overspeed detection level as a percentage of maximum output frequency (E1-04).
Setting Range: 0.0 to 2.0s
Factory Default: 0.0s
Sets the elapsed time from when an overspeed condition is detected to when a fault occurs.
A fault signal is output to stop operation after the absolute value of the motor speed exceeds the set
value of F1-08 and after the time set to F1-09 elapses. The stopping method is set by F1-03.
When parameter A1-02=1 [V/f w/PG] the factory setting will be 1.0. When parameter A1-02=3 [Flux
Vector] the factory setting will be 0.0.
