LED unit digit: Overvoltage interference suppression
0: Disable
1: Enable When this function is activated, the inverter will take intellectualized judge for over voltage fault, only
respond for true fault signal, suppresses the interference. It may causes alarm delay, should be used with caution
LED ten digit: SC interference suppression
0: Disable
1: SC interference suppression 1 When this function is activated, the inverter will take intellectualized judge for SC
fault, only respond for true fault signal, suppresses the interference. It may causes alarm delay, should be used with
caution.
2: SC interference suppression 2 It has strong SC interference suppression ability compare to SC interference
suppression 1. It may causes alarm delay, should be used with caution.
LED hundred digit: over current interference suppression
0: Disable
1: Over current interference suppression 1 When this function is activated, the inverter will take intellectualized
judge for over current fault, only respond for true fault signal, suppresses the interference. It may causes alarm
delay, should be used with caution.
2: Over current interference suppression 2 It has strong over current interference suppression ability compare to
over current interference suppression 1 It may causes alarm delay, should be used with caution.
LED thousand digit: over current in deceleration suppression
0: Disable
1: Enable When this function is activated, the current limit function will be executed if over current occurs during the
deceleration.
2: Enable frequency reduce for protecting over current. Selects this value for 2, if the output current achieve to
[E-52]
current threshold given setting, the inverter will decelerate according to the
[F-23]
deceleration time given
setting, when after the output current lower to
[E-52]
current threshold, inverter will accelerate to frequency
reference given according to
[F-22]
acceleration time given setting.
