Station number setting (Pr. 542)
Use Pr. 542 Communication station number (CC-Link) to set station number of the inverter. Set this parameter within the
range of 1 to 64.
NOTE
Use different station numbers for different devices. (If different devices have the same station number, the
communication cannot be performed properly.)
Connection example
Programmable controller

master module
Station 00
REMARKS
• Set consecutive numbers for the station numbers. (Do not skip a number in sequence like "station number 1 - station number 2-
station number 4".)
The station number does not have to match with the physical connection sequence. (There is no problem with having the physical
connection sequence like "station number 1 - station number 3 - station number 4 - station number 2".)
• One inverter occupies one station. (One remote device station)
• "L.ERR" LED flickers if the setting is changed. When power is switched ON again, the setting value is applied and the LED
turns OFF.
