F1: Error Detection for V/f Control with PG
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. Refer to C5: Automatic Speed
Regulator (ASR) on page 129 for details on how to activate and tune the function.

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 F1-02/03/04. The table below list the stopping methods and the
parameter setting values.
Table 5.24 Stopping Methods for PGo, oS, dEv Detection
Description Setting
Ramp to Stop (uses the deceleration time set to C1-02) 0
Coast to Stop 1
Fast-stop (uses the Fast-stop time set to C1-09) 2
Alarm only 3
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.
n
F1-02: Operation Selection at PG Open Circuit (PGo)
Sets the stopping method when a PG open circuit fault (PGo) occurs. Refer to Table 5.24 for setting explanations.
No. Parameter Name Setting Range Default
F1-02 Operation Selection at PG Open Circuit (PGo) 0 to 3 1
n
F1-03: Operation Selection at Overspeed
Sets the stopping method when an overspeed (oS) fault occurs. Refer to Table 5.24 for setting explanations.
No. Parameter Name Setting Range Default
F1-03 Operation Selection at Overspeed (oS) 0 to 3 1
n
F1-04: Operation Selection at Deviation
Sets the stopping method when a speed deviation (dEv) fault occurs. Refer to Table 5.24 for setting explanations.
No. Parameter Name Setting Range Default
F1-04 Operation Selection at Deviation (dEv) 0 to 3 3
n
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. Parameter Name Setting Range Default
F1-08 Overspeed Detection Level 0 to 120% 115%
F1-09 Overspeed Detection Delay Time 0.0 to 2.0 s 1.0 s
n
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.
No. Parameter Name Setting Range Default
F1-10 Excessive Speed Deviation Detection Level 0 to 50% 10%
F1-11 Excessive Speed Deviation Detection Delay Time 0.0 to 10.0 s 0.5 s
n
F1-14: PG Open-Circuit Detection Time
Sets the time required to detect PGo if no pulse signal is present at terminal RP.
No. Parameter Name Setting Range Default
F1-14 PG Open-Circuit Detection Time 0.0 to 10.0 s 2.0 s
