2.7 F: Options
The drive ramps the motor to stop in the deceleration time. Fault relay output terminal MA-MC turns ON, and MB-
MC turns OFF.
1 : Coast to Stop
The output turns off and the motor coasts to stop. Fault relay output terminal MA-MC turns ON, and MB-MC turns
OFF.
2 : Fast Stop (Use C1-09)
The drive stops the motor in the deceleration time set in C1-09 [Fast Stop Time]. Fault relay output terminal MA-MC
turns ON, and MB-MC turns OFF.
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 for Alarm [H2-01 to H2-03 = 10] activates.
Note:
When A1-02 = 6 [Control Method Selection = AOLV/PM], the drive will automatically set F1-03 = 1 [Coast to Stop]. You cannot change
this value.

Select
(0383)
When the difference between the frequency reference and the motor speed is more than the value set in F1-10 [Speed
Deviation Detection Level] for longer than the time set in F1-11 [Speed Deviation Detect DelayTime], the drive will
detect dEv.
0 : Ramp to Stop
The drive ramps the motor to stop in the deceleration time. Fault relay output terminal MA-MC turns ON, and MB-
MC turns OFF.
1 : Coast to Stop
The output turns off and the motor coasts to stop. Fault relay output terminal MA-MC turns ON, and MB-MC turns
OFF.
2 : Fast Stop (Use C1-09)
The drive stops the motor in the deceleration time set in C1-09 [Fast Stop Time]. Fault relay output terminal MA-MC
turns ON, and MB-MC turns OFF.
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 for Alarm [H2-01 to H2-03 = 10] activates.

Refer to the option card installation manual for more information about how to set the encoder pulse output sequence
and make sure that it is correct.
0 : Pulse A leads in FWD Direction
1 : Pulse B leads in FWD Direction

V/f CL-V/f OLV CLV AOLV
Sets the method to stop the motor or let the motor continue operating when the drive detects dEv
[Speed Deviation].
V/f CL-V/f OLV CLV AOLV
Sets the output sequence for the A and B pulses from the encoder, assuming that the motor is
operating in the forward direction.
