Changing the control logic

The input signals are set to source logic (SOURCE) when shipped from the factory.
To change the control logic, the jumper connector on the control circuit terminal block must be moved to the other
position.
(The output signals may be used in either the sink or source logic independently of the jumper connector position.)
CAUTION
Turn off the inverter power before switching a jumper connector.

Description
Select one e.g. output frequency from
monitor items.
*3
The output signal is proportional to the
magnitude of the corresponding
monitoring item.
With the PU connector, communication can be made through RS-485.
