Phase supervision of the supply voltage
0 = No action
2 = Fault
By setting the parameter value to zero, the phase supervision of the supply voltage will not
cause tripping
7.19
Thermistor input of I/O-Expander
0 = No action
1 = Warning
2 = Fault
The thermistor connected to the thermistor input of the I/O-expander board supervises the
temperature of the motor. With parameter 7.19 the response of the frequency converter
can be programmed when the thermistor indicates overtemperature.
7.20
Response to fieldbus fault
0 = No response
1 = Warning message
2 = Fault message, stop mode after fault according to parameter 4.7. A warning or a
fault action and message is generated from the fieldbus card if the error occurs of the
bus system physical layer.
