12 Descriptions of Parameter Settings | VFD-ED
Two MO terminals are affected by this parameter and should be set up as:
MO = 10: Low voltage waning (LV)
MO = 11: Fault Indication
Number of Times to Retry after Fault
Control Mode
VF VFPG SVC FOCPG FOCPM
Default: 0
Settings 0–10 times
To determine the number of times to retry when the following faults occur:
1: Over-current during acceleration (ocA)
2: Over-current during deceleration (ocd)
3: Over-current during constant speed (ocn)
4: Ground fault (GFF)
6: Over-current at stop (ocS)
7: Over-voltage during acceleration (ovA)
8: Over-voltage during deceleration (ovd)
9: Over-voltage during constant speed (ovn)
10: Over-voltage at stop (ovS)
11: Low voltage during acceleration (LvA)
12: Low voltage during deceleration (Lvd)
13: Low voltage during constant speed (Lvn)
14: Low voltage at stop (LvS)
15: Input Phase loss (PHL)
After every retry attempt, the number of times to retry is automatically reduced by one as displayed on the
keypad.
The principles for the number of times to reset:
1. Reset the fault manually.
2. After running normally for 10 minutes, the motor drive returns to the prior setting.
3. The motor drive is powered on and powered off again.
Time Interval between Retries
Control Mode
VF VFPG SVC FOCPG FOCPM
Default: 10.0
Settings 0.5–600.0 sec.
Determines the time interval between retries when the following faults occur:
1: Over-current during acceleration (ocA)
2: Over-current during deceleration (ocd)
3: Over-current during constant speed (ocn)
4: Ground fault (GFF)
6: Over-current at stop (ocS)
7: Over-voltage during acceleration (ovA)
8: Over-voltage during deceleration (ovd)
9: Over-voltage during constant speed (ovn)
10: Over-voltage at stop (ovS)
11: Low voltage during acceleration (LvA)
