Omron Q2V Series Technical Manual page 545

The output turns off and the motor coasts to stop. The output terminal set for Fault [H2-01 to H2-03 = 3]
activates.
2 : Fast Stop (C1-09)
The drive stops the motor in the deceleration time set in C1-09 [Fast Stop Time]. The output terminal set for Fault
[H2-01 to H2-03 = 3] activates.
3 : Alarm Only
The keypad shows oS and the drive continues operation. Only use this setting in special conditions to prevent
damage to the motor and machinery. The output terminal set to Alarm [H2-01 to H2-03 = 4] activates.
Note:
• When A1-02 = 0 [Control Method = V/f Control], set H6-01 = 3 [PI Pulse Train Function = PG Feedback] to enable this parameter.
• When A1-02 = 6 [Control Method = PM AOLVector], the drive will automatically set F1-03 = 1 [Coast->Stop]. You cannot change
this value.

F1-04: Speed Dev Detection Select
No.
Name
(Hex.)
F1-04 Speed Dev Detection Select
(0383)
When the difference between the frequency reference and the motor speed is more than the value set in F1-10
[Speed Dev Level] for longer than the time set in F1-11 [Speed Dev Delay Time], it will trigger dEv.
Note:
When A1-02 = 0 [Control Method = V/f Control], set H6-01 = 3 [PI Pulse Train Function = PG Feedback] to enable this parameter.
0 : Ramp->Stop
The drive ramps the motor to stop in the deceleration time. The output terminal set for Fault [H2-01 to H2-03 =
3] activates.
1 : Coast->Stop
The output turns off and the motor coasts to stop. The output terminal set for Fault [H2-01 to H2-03 = 3]
activates.
2 : Fast Stop (C1-09)
The drive stops the motor in the deceleration time set in C1-09 [Fast Stop Time]. The output terminal set for Fault
[H2-01 to H2-03 = 3] activates.
3 : Alarm Only
The keypad shows dEv and the drive continues operation. Only use this setting in special conditions to prevent
damage to the motor and machinery. The output terminal set to Alarm [H2-01 to H2-03 = 4] activates.

F1-08: Overspeed Level
No.
Name
(Hex.)
F1-08 Overspeed Level
(0387)
When the motor speed is more than the value set in F1-08 for longer than the time set in F1-09 [Overspeed Delay
Time], the drive will detect oS.
Note:
When A1-02 = 0 [Control Method = V/f Control], set H6-01 = 3 [PI Pulse Train Function = PG Feedback] to enable this parameter.
■
F1-09: Overspeed Delay Time
No.
Name
(Hex.)
F1-09 Overspeed Delay Time
(0388)
When the motor speed is more than the value set in F1-08 [Overspeed Level] for longer than the time set in F1-
09, the drive will detect oS.

V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the method to stop the motor or let the motor continue to operate when the drive detects dEv
[Speed Deviation].
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the detection level of oS [Overspeed] as a percentage when the maximum output frequency
is 100%.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the length of time that the speed feedback must be more than the F1-08 level to cause oS
[Overspeed].
