725 Automatic restart: Number of tries after external fault trip
(2.8.9)
This parameter determines how many automatics restarts can be made during the trial
time set by ID718.
0 = No automatic restart after External fault trip
>0 = Number of automatic restarts after External fault trip
726 Automatic restart: Number of tries after motor temperature fault trip
(2.8.8)
This parameter determines how many automatics restarts can be made during the trial
time set by ID718.
0 = No automatic restart after Motor temperature fault trip
>0 = Number of automatic restarts after the motor temperature has
returned to its normal level
727 Response to undervoltage fault
(2.6.5)
0 = Fault stored in fault history
1 = Fault not stored in fault history
For the undervoltage limits, see the product's User’s Manual.
728 4mA reference fault: preset frequency reference
(2.6.2)
If the value of parameter ID700 is set to 3 and the 4mA fault occurs then the frequency
reference to the motor is the value of this parameter.
730 Input phase supervision
(2.6.4)
0 = No response
1 = Warning
2 = Fault, stop mode after fault according to ID506
3 = Fault, stop mode after fault always by coasting
The input phase supervision ensures that the input phases of the frequency converter
have an approximately equal current.
731 Automatic restart 1
(2.20)
The Automatic restart is taken into use with this parameter.
0 = Disabled
1 = Enabled
The function resets the following faults (max. three times) (see Vacon NX User’s Manual,
Chapter 9):
• Overcurrent (F1)
• Overvoltage (F2)
• Undervoltage (F9)
• Frequency converter overtemperature (F14)
• Motor overtemperature (F16)
• Reference fault (F50)
