Operating & Mounting instructions – 8 074 143.03/03 – Page 51
Parameters
In the event of a low-voltage trip during operation, e.g. mains failure, the inverter switches to
impulse lock. If the voltage returns within the time set with b002, the inverter can be started again.
Otherwise, the unit shuts down with the message undervoltage.
If parameter b001 is set to 01, the time period b003 can be set after which the frequency inverter
tries to start-up again (after return of power). Of course, this will only happen if the power returns
within the set time.
b004
Undervoltage trip during stop VIC 00 to 02 00
Setting Function
00 Monitoring of undervoltage not active
01 Monitoring of undervoltage always active
02 Monitoring of undervoltage only during operation active
b005
Undervoltage Number of retry VIC 00 or 01 00
Setting Function
00 Tries to reset 16 times, then error message occurs
01 Tries to reset any times
b006
Input phase loss protection VIC 00 or 01 00
Setting Function
00 not active
01 active
b007
Matching frequency setting VIC 0,00...400,0 Hz 0,00Hz
This parameter defines the motor speed dependent behaviour at reset.
If the speed of the motor is higher than the frequency set with b007, the inverter tries to catch on the
fly and to accelerate to the set reference value.
If the speed of the motor is lower thant the frequency set with b007, a reset is done at 0,0 Hz.
