 Setting the IP address with the rotary switches
Set a value other than "0 (H00)" or "255 (HFF)" to specify a station number using the rotary switches. The setting range is
from "1 (H01)" to "254 (HFE)". The setting is applied after an inverter reset or at the next power-ON.

First octet
The settings of the master station are used. (The settings from Pr.434 to Pr.436 are
Second octet
invalid.)
Third octet
Fourth octet The rotary switch setting is enabled regardless of the setting in Pr.437.
Set the arrow () of each switch to the number or letter (0-9, A-F) corresponding to the desired station number.
• Setting example
Setting for station number 1 (H01):
Set the arrow () of X16 to "0" and the arrow () of X1
to "1".
NOTE
• Set the rotary switches before turning ON the inverter. Do not change the setting while the power is ON. Doing so may cause
an electric shock.
• Set the rotary switch exactly onto one of the numbers. Otherwise normal data communication cannot be established.
• Set a unique station number. (If different devices have the same station number, communication cannot be performed
properly. If an error occurs due to a duplicated number, assign the station number correctly, then reset the master or the
inverter power.)
• Station numbers do not have to be consecutive numbers.
• The rotary switch setting can be displayed on the operation panel when "45" is set in Pr.52 Operation panel main monitor
selection.
 Setting the IP address with parameters (Pr.434 to Pr.437)
Set the rotary switches to "0 (H00) or 255 (HFF)" to specify the IP address of the inverter using Pr.434 to Pr.437.
The setting is applied after an inverter reset or at the next power-ON.

Fourth octet Pr.437
• Enter the inverter network number in Pr.436 IP address 3.
• The setting range of Pr.436 is "0 to 255", but its active range is "1 to 254". The values out of the active range are invalid
because such values cannot be transmitted to the master station.
• Use Pr.437 IP address 4 to enter the station number of the inverter.
• The setting range of Pr.437 is "0 to 255", but its active range is "1 to 254". The values out of the active range are invalid
because such values cannot be transmitted to the master station.
NOTE
• Set a unique station number. (If different devices have the same station number, communication cannot be performed
properly. If an error occurs due to a duplicated number, assign the station number correctly, then reset the master or the
inverter power.)
• Station numbers do not have to be consecutive numbers.
