5.6 F: Simple FeedbackSettings
u
F1: Encoder/PG Feedback Settings
The F1 parameters are used to set the drive up for single channel simlpe closed loop operation using the pulse train input.
n
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.
Parameter 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
Note: Due to potential damage to motor and machinery, the “Alarm only” setting should be used only under special circumstances.
n
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.
Parameter F1-03 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
Note: Due to potential damage to motor and machinery, refrain from using the “Alarm only” setting except under special
circumstances.
n
F1-04, F1-10, F1-11: Operation at Speed Deviation (dEv), Detection Level, Delay Time
A speed deviation error (dEv) is triggered when the difference between the speed reference and the speed feedback
exceeds the value set in F1-10 for longer than the time set in F1-11. The stopping method when a speed deviation fault
occurs can be selected in parameter F1-04.
Settings for Parameter F1-04:
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 (drive continues operating while “dEv” flashes on the screen)
