Description of Parameters
726 Automatic restart: Number of
tries after motor temperature
fault trip
234567 (P1.8.8)
This parameter determines how many automatic 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 234567 (P1.7.5)
1 Warning
2 Fault, stop mode after fault according to ID506
3 Fault, stop mode after fault always by coasting
For the undervoltage limits, see 9000X AF Drives User Manual, Table 4-2.
728 Reference fault: preset
frequency reference
234567 (P1.7.2)
If the value of parameter ID700 is set to 3 and the 4 mA fault occurs, then the
frequency reference to the motor is the value of this parameter.
730 Input phase supervision 234567 (P1.7.4)
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 approximately equal currents.
731 Automatic restart 1 (P1.20)
The Automatic restart is used when this parameter is enabled.
0 Disabled
1 Enabled
