Electronic bypass sequence function
●
When operating the motor at 60 Hz (or 50 Hz), the motor can be more efficiently operated with a
commercial power supply. In addition, if the motor cannot be stopped for a long period of time
even for an inverter maintenance and inspection, it is recommended that a commercial power
supply circuit be installed.
●
When switching between inverter operation and commercial power supply operation, commer-
cial power supply may be accidentally applied to the output side of the inverter. To avoid such
situation, provide an interlock where the magnetic contactor at the commercial power supply
side turns ON at turn OFF of the magnetic contactor at the inverter output side.
The inverter's electronic bypass sequence that outputs timing signals for the magnetic contactors
can act as a complicated interlock between the commercial power supply operation and the
inverter operation.
Connection diagram
●
A typical connection diagram of the electronic bypass sequence is shown below.
NOTE
The commercial power supply operation is not available with Mitsubishi vector control dedicated
motors (SF-V5RU).
