Description of Parameters
644 Torque speed limit 6 (P1.10.7)
With this parameter the maximum frequency for the torque control can be selected.
0 Maximum frequency, ID102
1 Selected frequency reference
2 Preset speed 7, ID130
700 Response to the reference fault 234567 (P1.7.1)
0 No response
1 Warning
2 Warning, the frequency from 10 seconds back is set as reference
3 Warning, the Preset Frequency (ID728) is set as reference
4 Fault, stop mode after fault according to ID506
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 234567 (P1.7.3)
0 No response
1 Warning
2 Fault, stop mode after fault according to ID506
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 234567 (P1.7.6)
0 No response
1 Warning
2 Fault, stop mode after fault according to ID506
3 Fault, stop mode after fault always by coasting
Output phase supervision of the motor ensures that the motor phases have
approximately equal currents.
703 Earth fault protection 234567 (P1.7.7)
0 No response
1 Warning
2 Fault, stop mode after fault according to ID506
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.
