F: Option Settings
♦ F1: Encoder/PG Feedback Settings
The F1 parameters are used to set the drive up for operation using a motor encoder option card. Note that all speed
feedback option cards must be connected to the CN5-C port.
■ F1-01: Encoder 1 Resolution
Sets the encoder resolution.

■ F1-02, F1-14: PG Open (PGo) Circuit Operation Selection, Detection Time
A PGo fault is triggered if the drive receives no pulse signal for longer than the time set in F1-14. Set the stopping
method for a PGo fault in parameter F1-02.

Param eter F1-02 Settings:
Setting 0: Ramp to stop (uses the deceleration ramp set to C1-02)
Setting 1: Coast to stop
Setting 2: Fast Stop (uses the Fast Stop ramp set to C1-09)
Setting 3: Alarm only
N ote: Due to potential damage to m otor and machinery, the “A larm only” setting should be used only under special circumstances.
■ F1-03, F1-08, F1-09: Overspeed (oS) Operation Selection, Detection Level, Delay Time
An oS fault is triggered when the speed feedback exceeds the value set in F1-08 for longer than the time set in F1-09. Set
the stopping method for an oS fault in parameter F1-03.
