■ 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 speed reference and the speed feedback
exceeds the value set in F1-10 for longer than the time set in F1-11. The stopping method when a speed deviation fault
occurs can be selected in parameter F1-04.
No.

Setting 1: Coast to stop
Setting 2: Fast Stop (uses the Fast Stop ramp set to C1-09)
Setting 3: Alarm only (drive continues operating while “dEv” flashes on the screen)
■ F1-05: Encoder 1 Rotation Direction Selection
Determines the direction indicated by the motor encoder signal.

■ F1-06: PG1 Pulse Monitor Output Division Ratio
Sets the ratio between the pulse input and the pulse output o f a speed feedback 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)

■ F1-18: dv3 Detection Selection (CLV/PM)
Sets the number o f times the drive will detect a dv3 situation before triggering a dv3 fault. The drive detects a dv3
condition when the torque reference and speed reference are in opposite directions while the difference between the
actual motor speed and the speed reference is greater than 30%. Setting F1-18 to 0 disables dv3 detection.
No.

Note: A comm on cause for a dv3 fault is the incorrect setting o f E5-11. M ake sure the correct encoder offset has been entered to E5-11.
■ F1-19: dv4 Detection Selection (CLV/PM)
Sets the number o f pulses necessary to trigger a dv4 fault when there is a motor speed deviation opposite to the frequency
reference. Setting F1-19 to 0 disables dv4 detection.
No.
