2.9.1.7
MCB at Fault
Defines action for the main circuit breaker when the drive has a fault.
F1 Over Current, F31 Hardware IGBT and F41 Software IGBT will open MCB immediately
regardless of the setting of this parameter.
0 = Keep closed
1 = Open at any fault situation
2.9.1.8
Start Fault Delay
When using the master-follower system for example for a shaft generator, this
parameter defines the fault delay if both drives are not started.
P2.9.1.9 Quick
Stop
Response
ID1758
This function will stop the drive at any case. This parameter is used to select which
action is shown on keypad.
1 = Warning
2 = Fault
P2.9.1.10 Reactive Error Trip Limit
ID1759
Limit for the reactive current for the line fault detection, when the reactive current is
less than the value of parameter Line Synch fault.
P2.9.1.11
MCB
Fault
Delay
ID1521
The delay for the main circuit breaker open fault. The delay between the control relay
close command of the main circuit breaker and the acknowledge signal of the main
circuit breaker. If the acknowledge signal is not received within this time, a fault F64 will
be generated.
P2.9.1.12 Line Phase Supervision
ID702
Defines the response when the drive notices that one of the input phases is missing.
0 = No response
1 = Warning
2 = Fault, stop mode after fault according to Stop Function
3 = Fault, stop mode after fault always by coasting
P2.9.1.13 Response to the 4mA reference fault ID700
The 4 mA protection monitors the analogue input signal level from Analogue Input 1 and
Analogue Input 2. The monitoring function is active when the signal Custom Minimum is
bigger than 16.00%. A fault or warning is generated when the signal goes below 3.5 mA
for 5 seconds or below 0.5 mA for 0.5 seconds.
0 = No response
1 = Warning
2 = Fault
