Motors can be connected to inverters
either individually or in parallel. For
parallel motor operation each motor
should have an overload protection
relay fitted. Set parameter P077 to 0
for multi-motor operation mode.
For wiring guidelines to minimise the
effect of electro-magnetic
interference (EMI), refer to the
relevant section of this manual.
