• 0.75 to 6kHz (200V/400V:90 to 500kW) |
The carrier
frequency may drop automatically according to the ambient
temperature or output current to protect the inverter. This
protective operation can be canceled by function code H98. |

Restart
after momentary
power failure |
•The
inverter restarts upon recovery from power failure without
stopping the motor.
• In the "operation continuation mode,"
recovery of the power supply is waited for while the output
frequency slightly drops.
• Selection can be made among starting at 0Hz,
starting at the frequency immediately before the momentary
power failure,
and starting at a set frequency for the starting method
after power recovery. |

| Line/inverter
switching |
•Line/inverter
switching (starting at line frequency) can be made with a
digital input signal (SW50, SW60).
• A built-in line/inverter switching sequence performs
sequence control with a digital input signal (ISW50, ISW60)
to
output a signal (SW88, SW52-1, SW52-2) for controlling an
external magnetic contactor (MC). As a built-in
sequence, two types can be selected, including the one
switching automatically to the line upon an inverter alarm. |
