7.15.6
Current imbalance protection
This protection detects if there is imbalance in the
currents. Normally it should be same current amount in
all three phases. If the current amount is different in the
phases the engine can go bumpy.
This protection is only operational in the Top of ramp
state.
Current imbalance
protection is configured with the
following parameters:
Parameter
14.11 Curr imb level
14.12 Curr imb trip time
14.13 Curr imb delay time
14.14 Curr imb out
14.15 Curr imb operation
7.15.7
Over voltage protection
This proection detects if the main voltage is too high.
Check the main voltage.
This protection is not operational
in the Standby state.
Over voltage protection is configured with the
following parameters:
Parameter
15.01 Over voltage level
15.02 Over voltage trip time
15.03 Over voltage out
15.04 Over voltage op
7.15.8
Under voltage protection
This protection detects if the main voltage is too low.
Check the main voltage.
Under voltage protection is configured with the
following parameters:
Parameter
15.05 Under voltage level
15.06 Under voltage trip time
15.07 Under voltage op
15.08 Under voltage out
