Omron SYSDRIVE 3G3FV, User Manual, Page: 154 / 400

5-32
Parameter F1-08 sets the overspeed detection level as a percentage of the maximum output frequency.
Parameter F1-09 sets the length of time that the motor speed must exceed the overspeed detection
level in order to generate an overspeed fault.

PG Speed Deviation Settings (F1-04, F1-10, and F1-11)
PG speed deviation refers to the difference between the actual motor speed and the reference com-
mand speed. These parameters set the conditions for a PG speed deviation fault and the stopping
method that is used when a PG speed deviation fault occurs; they cannot be changed during operation.
Parameter F1-04 sets the conditions for detecting a PG speed deviation fault and the stopping method
to be used when a fault is detected.

Settings
Setting Stopping method Function
0 Ramp to Stop
(C1-02)/Fault Detect when deviation occurs with the frequence reference matching (within
the L4-02 detection range) the output frequency.
1 Coast to Stop/Fault Detect when deviation occurs with the frequence reference matching (within
the L4-02 detection range) the output frequency.
2 Fast Stop
(C1-09)/Fault Detect when deviation occurs with the frequence reference matching (within
the L4-02 detection range) the output frequency.
3 Continue/Alarm
Only Detect when deviation occurs with the frequence reference matching (within
the L4-02 detection range) the output frequency.
4 Ramp to Stop
(C1-02)/Fault Detect when deviation occurs with the frequence reference matching (within
the L4-02 detection range) the motor speed (PG feedback).
5 Coast Stop/Fault Detect when deviation occurs with the frequence reference matching (within
the L4-02 detection range) the motor speed (PG feedback).
6 Fast Stop
(C1-09)/Fault Detect when deviation occurs with the frequence reference matching (within
the L4-02 detection range) the motor speed (PG feedback).
7 Continue/Alarm
Only Detect when deviation occurs with the frequence reference matching (within
the L4-02 detection range) the motor speed (PG feedback).
Note 1. In order to detect faulty contacts, and so on, inserted at the Inverter output side, select detec-
tion when the frequency reference matches the output frequency.
Note 2. The detection conditions vary as shown below depending on the software version. In Ver.
VSG101114 and later versions, both functions are provided.
