Response to the 4mA reference fault
(2.7.1)
0
= No response
1
= Warning
2
= Warning, the frequency from 10 seconds back is set as reference
3
= Warning, the Preset Frequency (P
) is set as reference
4
= Fault, stop mode after fault according to
5
= 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 information can also be programmed into digital output DO1 or relay outputs RO1
and RO2.
701
Response to external fault
(2.7.3)
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 programmable digital inputs DIN3. The information can also be programmed into
digital output DO1 and into relay outputs RO1 and RO2.
702
Output phase supervision
(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
Output phase supervision of the motor ensures that the motor phases have an
approximately equal current.
703
Earth fault 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
Earth fault protection ensures that the sum of the motor phase currents is zero. The
overcurrent protection is always working and protects the frequency converter from earth
faults with high currents.
704
Motor thermal protection
(2.7.8)
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 protection, i.e. setting parameter to
0
, will reset the thermal stage of
the motor to 0%. See chapter 6.3.
