700
Response to the 4mA reference fault
(2.7.1)
0 = No response
1 = Warning
2 = Fault, stop mode after fault according to
3 = Fault, stop mode after fault always by coasting
A warning or a fault action and message is generated if the 4…20 mA reference signal is used
and the signal falls below 3.5 mA for 5 seconds or below 0.5 mA for 0.5 seconds. The informa-
tion can also be programmed into relay outputs RO1 or RO2.
701
Response
to
external
fault
(2.7.2)
0 = No response
1 = Warning
2 = Fault, stop mode after fault according to
3 = Fault, stop mode after fault always by coasting
A warning or a fault action and message is generated from the external fault signal in the pro-
grammable digital input DIN3. The information can also be programmed into relay outputs RO1
or RO2.
702
Output
phase
supervision
(2.7.5)
0 = No response
1 = Warning
2 = Fault, stop mode after fault according to
3 = Fault, stop mode after fault always by coasting
Output phase supervision of the motor ensures that the motor phases have an approximately
equal current.
703
Earth
fault
protection
(2.7.6)
0 = No response
1 = Warning
2 = Fault, stop mode after fault according to
3 = Fault, stop mode after fault always by coasting
Earth fault protection ensures that the sum of the motor phase currents is zero. The over-
current protection is always working and protects the frequency converter from earth faults
with high currents.
704
Motor
thermal
protection
(2.7.7)
0 = No response
1 = Warning
2 = Fault, stop mode after fault according to
3 = Fault, stop mode after fault always by coasting
If tripping is selected the drive will stop and activate the fault stage. Deactivating the protec-
tion, i.e. setting parameter to 0, will reset the thermal stage of the motor to 0%.
