7.17.7
Overvoltage protection
This protection senses if the main voltage is too high.
This protection does not operate in the Standby state.
Overvoltage protection has these parameters:
Parameter
15.01 Overvoltage level
15.02 Overvoltage trip time
15.03 Overvoltage out
15.04 Overvoltage op
7.17.8
Under voltage protection
This protection only operates in the Top of ramp state.
Under voltage protection has these parameters:
Parameter
7
15.05 Under voltage level
15.06 Under voltage trip time
15.07 Under voltage op
15.08 Under voltage out
7.17.9
Voltage imbalance protection
This protection senses voltage imbalance. Normally
there is the same voltage in all 3 phases. If the voltage is
different in the phases, the engine can run bumpy.
Voltage imbalance protection has these parameters:
Parameter
15.09 Voltage imb level
15.10 Voltage imb out
15.11 Voltage imb op
15.11 Voltage imb trip time
