5.6 F: Option Settings
■ 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.
F1-04
F1-10
F1-11
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
No.
F1-05
<1> Determined by the control mode: 0 when A1-02 = 3, 1 when A1-02 = 7.
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:
(1 + n)
f = f
Pulse Input Pulse Output
Example: To have a ratio of 1/32 between the speed feedback option card pulse input and output, set F1-06 = 032.
No.
F1-06
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.
No.
F1-18
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.
