■ F1-10, F1-11: Excessive Speed Deviation Detection Level, Delay Time
F1-10 sets the detection level for a speed deviation (dEv) fault as a percentage of the maximum output frequency. The
speed feedback has to exceed this level for longer than the time set in F1-11 before a fault is detected. Speed deviation is
the difference between actual motor speed and the frequency reference command.
■
F1-14: PG Open-Circuit Detection Time
Sets the time required to detect PGo if no pulse signal is present at terminal RP.
◆ F6: Communication Option Card
These parameters are to configure communication option cards and communication fault detection methods.
■
F6-01: Communications Error Operation Selection
Determines drive operation if a communication error occurs.
Setting 0: Ramp to Stop Using Current Accel/Decel Time
Setting 1: Coast to Stop
Setting 2: Fast-stop Using C1-09
Setting 3: Alarm Only, Continue Operation
■ F6-02: External Fault from Comm. Option Detection Selection
Determines the detection method of an external fault initiated by a communication option (EF0).
Setting 0: Always Detected
Setting 1: Detection During Run Only
■ F6-03: External Fault from Comm. Option Operation Selection
Determines the operation when an external fault is initiated by a communication option (EF0).
Setting 0: Ramp to Stop Using Current Accel/Decel Time
Setting 1: Coast to Stop
Setting 2: Fast-stop Using C1-09
Setting 3: Alarm Only, Continue Operation
