*1 When the PLC power supply common may be connected to the drive 11 terminal to input analog frequency setting
signals from the PLC, use this connection and set the SW7 switch 1 to EXT and 2 to PLC to prevent the FWD and
REV terminals from turning on due to sneak path current when the PLC power is turned off.
*2 With this connection, the power is supplied from the PLC power supply to the external thermal O/L relay. So, OH2 trip
is activated by PLC power-off with the drive turned on.
*3 To prevent drive trip with OH2 when the PLC power being turned off, do not select the THR te rminal function and use
the drive electronic thermal O/L relay.
*4 When the X3 terminal is used as the PLC terminal, no function that can be set with E03 can be used. The X3 terminal
is dedicated to the PLC .
