5.6 F: Option Settings
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 99
No.
F1-05
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.
■
F1-19: dv4 Detection Selection (CLV/PM)
Sets the number of 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.
F1-19
Note: A common cause for a dv4 fault is the incorrect setting of E5-11. Make sure the correct encoder offset is set to E5-11.
