Deviation 4 Detection Selection

Sets the number of pulses necessary to cause dv4 [Inversion Prevention Detection].

128
(0 - 5000)

The drive detects a dv4 [Inversion Prevention Detection] faultwhen the pulses in a reverse direction to the speed reference are input for longer than the time set in F1-19.
Note:
-
Refer to the E5-11 [Encoder Z-Pulse Offset] value and the Δθ value shown on the motor nameplate. An incorrect E5-11 value will frequently be the cause of a dv4 fault.
-
When you use the drive in an application that rotates the motor from the load side in the reverse direction of the speed reference, set F1-19 = 0.
