(note)
Note : Wire the cables for application of voltages to the contact outputs so that they
may be separated from the PLC power at the no-fuse breaker etc. If they are
connected to the same power supply as is used by the PLC, the inverter cannot
be changed during CC-Link communication.
INSTALLATION AND WIRING
Connect to the commercial power supply. Keep these terminals
unconnected when using the high power factor converter.
Connect a three-phase squirrel-cage motor.
Connect the optional brake resistor across terminals P-PR (+-PR)
(not for 0.1K and 0.2K).
Connect the optional brake unit or high power factor converter.
Disconnect the jumper from terminals P-P1 (+-P1) and connect the
optional power factor improving DC reactor.
For grounding the inverter chassis. Must be earthed.
Turn on the MRS signal (20ms or longer) to
stop the inverter output.
Used to shut off the inverter output to bring
the motor to a stop by the electromagnetic
brake.
Used to reset the protective circuit activated. Turn on the RES
signal
for more than 0.1 second, then turn it off.
Common terminal for contact inputs for use in the source input
mode.
In the source input mode, connection with this terminal switches the
signal on and disconnection switches it off.
Common terminal for contact inputs for use in the sink input mode.
In the sink input mode, connection with this terminal switches the
signal on and disconnection switches it off.
Contact output indicating that the output has
been stopped by the inverter protective
function activated. 230VAC 0.3A, 30VDC
0.3A. Alarm: discontinuity across B-C
(continuity across A-C), normal: continuity
across B-C (discontinuity across A-C).
