◆ F1: PG Speed Control Card Settings

A one-track pulse signal can be connected to the drive pulse train input RP as speed feedback. Using this signal for slip
compensation improves the speed control accuracy. This function is only available for motor 1.
The F1 parameters determine how the error detection for the speed feedback signal works.

Operation at PG Fault Detection
■
The drive lets the user select from one of four possible operations when a fault occurs with the PG encoder. The operation
can be set up separately for each fault using parameters F1-02, F1-03, and F1-04. The table below list the stopping
methods and the parameter setting values.
Ramp to Stop (uses the deceleration time set to C1-02)
Fast-stop (uses the Fast-stop time set to C1-09)
NOTICE: Setting = 3: Alarm only will provide an alarm only while continuing to run the motor during abnormal PG fault conditions. This
may cause damage to machinery. Use caution when selecting this setting.
F1-02: Operation Selection at PG Open Circuit (PGo)
■
Sets the stopping method when a PG open circuit fault (PGo) occurs. Refer to
No.
F1-02
F1-03: Operation Selection at Overspeed
■
Sets the stopping method when an overspeed (oS) fault occurs. Refer to
No.
F1-03
■ F1-04: Operation Selection at Deviation
Sets the stopping method when a speed deviation (dEv) fault occurs. Refer to
No.
F1-04
F1-08, F1-09: Overspeed Detection Level, Delay Time
■
F1-08 sets the detection level for an overspeed (oS) fault as a percentage of the maximum output frequency. The speed
feedback has to exceed this level for longer than the time set in F1-09 before a fault is detected.
No.
