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.
n 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.
F1-04 Operation Selection at Deviation (dEv)
F1-10 Excessive Speed Deviation Detection Level
F1-11 Excessive Speed Deviation Detection Delay Time
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.

F1-32
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:
(1 + n)
f = f
m
Pulse Input Pulse Output
Example: Set F1-06 to 032 for a ratio of 1/32 between the PG card pulse input and output.
No.

n 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:
