Setting 0: Ramp to stop (uses the deceleration time set to C1-02)
Setting 1: Coast to stop
Setting 2: Fast Stop (uses the Fast Stop time 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.

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 frequency reference and the speed feedback exceeds
the value set in F1-10 for longer than the time set in F1-1. The stopping method when a speed deviation fault occurs can be
selected in parameter F1-04.
No. Parameter Name Option Port Setting Range Default
F1-04 Operation Selection at Deviation (dEv) CN5-B, CN5-C 0 to 3 3
F1-10 Excessive Speed Deviation Detection Level CN5-B, CN5-C 0 to 50% 10%
F1-11 Excessive Speed Deviation Detection Delay Time CN5-B, CN5-C 0.0 to 10.0 s 0.5 s
Settings for Parameter F1-04:
Setting 0: Ramp to stop (uses the deceleration time set to C1-02)
Setting 1: Coast to stop
Setting 2: Fast Stop (uses the Fast Stop time set to C1-09)
Setting 3: Alarm only (drive continues operating while “dEv” flashes on the screen)
n
F1-05, F1-32: PG 1, PG 2 Rotation Selection
Determines the direction indicated by the pulses from the PG feedback encoder for motor 1 and motor 2.
See PG option card instruction manual for details on setting the direction for the PG encoder and the motor.
No. Parameter Name Option Port Setting Range Default
F1-05 PG 1 Rotation Selection CN5-C 0, 1

F1-32 PG 2 Rotation Selection CN5-B 0, 1 0
<1> Default is 0 when A1-02 = 1 or 3. Default is 1 when A1-02 = 7.
Setting 0: A pulse leads with Forward run command
Setting 1: B pulse leads with Forward run command
n
F1-06, F1-35: PG 1, PG 2 Division Rate for PG Pulse Monitor
Sets the ratio between the pulse input and the pulse output of a PG option card as a three-digit number, where the first digit
(n) sets the numerator and the second and third digit (m) set the denominator as shown below:

F1-12, F1-13, F1-33, F1-34: PG 1, PG 2 Gear Teeth 1, 2 (V/f w/PG only)
Sets the gear ratio between the motor shaft and the PG encoder. F1-12 and F1-33 set the number of gear teeth on the motor
side, while F1-13 and F-34 set the number of gear teeth on the load side. The drive uses the formula below to calculate the
motor speed:
