Note
Be sure to 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 become eective until the
driver power is cycled.
Protocol
The protocol of RS-485 communication can be set using the SW5-No.2 of the
function setting switch2.
Factory setting:
OFF (Connecting with network converter)
SW5-No.2 Protocol
ON Modbus RTU mode
OFF Connecting with network converter
Address number
The address number (slave address) can be set using the address number
setting switch (SW1) in combination with the SW5-No.1 of the function
setting switch2. Make sure each address number (slave address) you set for
each driver is unique.
Factory setting
SW1: 0, SW5-No.1: OFF (Address number 0)

∗*
In the case of Modbus protocol, the address number 0 is reserved for
broadcasting, so do not use this address.
Transmission rate
The transmission rate can be set using the transmission rate setting switch
(SW4).
The transmission rate to be set should be the same as the transmission rate of
the master device.
Factory setting:
7 (Network converter)
SW4 Transmission rate (bps) SW4 Transmission rate (bps)
0 9600 5

1 19200 6
2 38400 7 Network converter
3 57600 8 to F Not used
4 115,200
Note
Do not set the SW4 to positions 5, 6 and 8 to F.
Termination resistor
The termination resistor for RS-485 communication (120
Ω
) can be set using
the SW3-No.4 of the function setting switch1.
Factory setting:
OFF (termination resistor disabled)
SW3-No.4 Termination resistor (120
Ω
)
OFF Disabled
ON Enabled
Operation
This section explains the minimum requirements in order to operate the
product. Refer to the USER MANUAL for details on other descriptions.
Setting the rotation speed
The rotation speed can be set using an external potentiometer (supplied) or
external DC voltage.
Turning the external potentiometer in the clockwise direction makes the
motor to rotate faster. Turning it in the counterclockwise direction makes the
motor to rotate slower.
Setting range: 100 to 4000 r/min

Note
•
For the speed setting by external DC voltage, a range of 0
to 5 VDC is set at the time of shipment. Therefore, even if
10 VDC is connected, the speed setting is enabled between
0 and 5 VDC. When setting the speed by a range of 0 to
10 VDC, it is required to change the parameter. Refer to the
USER MANUAL for details.
•
Be sure to set the external DC voltage to 10 VDC or lower.
When connecting the external DC power supply, make sure
the polarities are correct. If the polarities are reversed, the
driver may be damaged.
