■ 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.
Settings for Parameter F1-04:
Setting 0: Ramp to stop (uses the deceleration ramp set to C1-02)
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.
Refer to PG Encoder Setup on page 107 for details on how to set the direction for the encoder and the motor.
Setting 0: Phase A leads phase B with an Up command.
Setting 1: Phase B leads phase A with an Up command.
■ F1-06: PG1 Pulse Monitor Output Division Ratio
Sets the ratio between the pulse input and the pulse output of 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:
Example: To have a ratio of 1/32 between the speed feedback option card pulse input and output, set F1-06 = 032.
■
F1-18: dv3 Detection Selection (CLV/PM)
Sets the number of 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.
Note: A common cause for a dv3 fault is the incorrect setting of E5-11. Make sure the correct encoder offset has been entered to E5-11.
