Protections

7.7.1 General

P2.7.1.1 Response to thermistor fault
0 = No response
1 = Warning
2 = Fault (the drive will stop modulation leaving MCB closed)
3 = Fault, DC off (MCB open)
Setting the parameter to 0 will deactivate the protection.
P2.7.1.2 Response to Input Filter over temperature
This parameter defines a response to LCL over temperature fault. LCL fault is monitored
through digital input defined in parameter P2.2.1.3.
0 = No response
1 = Warning
2 = Fault (the drive will stop modulation leaving MCB closed)
3 = Fault, DC off (MCB open)
P2.7.1.3 Response to external fault
This parameter defines a response to external fault. If the drive monitors the state of
external fault input (value of
respond to the fault.
0 = No response
1 = Warning
2 = Fault (the drive will stop modulation leaving MCB closed)
3 = Fault, DC off (MCB open)
P2.7.1.4 MCB on Fault
This parameter defines response to ANY fault what occurs in the AFE.
0 = MCB is kept closed in case of fault
- Faults that have been defined to open MCB are still active.
1 = Any fault in the drive will open the MCB.
- Auto reset of MCC fault will be disabled with this selection.
P2.7.1.5 Charge Max Time
When drive charging options is used this parameter defines maximum time limit for
charging. Use suitably sized DC Charging resistor by checking Pulse loadability for time
duration set in for Max Charge Time parameter
