STEP2 Setting switches
Set the termination resistor and the address number with the switches.
Note
Turn o the driver power before setting the switches. If the switches are set while the power is still on, the new switch
settings will not be enabled.

Setting the address number setting switch
Set the address number (slave address) using the address number setting switch. Make sure each address number (slave
address) you set for each driver is unique.
Address number (slave address) 0 is reserved for broadcasting, so do not use this address.

The address number can also be set with the "Communication ID" parameter. (p.46) If the address number is set
using the parameter in a state where communication is not established, connect the
MEXE02
to set.

Setting the termination resistor
Set the termination resistor (120
Ω
) of RS-485 communication to the driver located the farthest away (positioned at the
end) from the host controller.
Set the termination resistor switch to enable the termination resistor. (OFF
⇒
ON)
Factory setting: OFF (termination resistor disabled)
STEP3 Setting the communication parameters
Turn on the driver power supply and check the communication parameters listed below using the
MEXE02
.
If communication is not established, reconsider the communication parameters of the driver.
Parameter name Factory setting
Communication ID −1: The switch setting of the driver is followed
Baudrate 4: 115,200 bps
Communication order 0: Even Address-High Word & Big-Endian
Communication parity 1: Even parity
Communication stop bit 0: 1 bit
Transmission waiting time 30 (3.0 ms)
Silent interval 0.0: Set automatically
