Name Description
POWER LED (Green)
This LED lit while the main power or
control power is input.
ALARM LED (Red)
This LED will blink when an alarm
generates (a protective function is
triggered). You can check the generated
alarm by counting the number of times the
LED blinks.
Internal potentiometer
(VR1)
Set the motor rotation speed.
Acceleration/
deceleration time
potentiometer (VR2)
Set the acceleration time and deceleration
time for the motor.
Torque limiting
potentiometer (VR3)
Set the torque limiting value of the motor.
Main power supply input
terminal [CN1]
Connect the main power supply.

C-DAT LED (Green)
This LED will illuminate when the driver
is communicating with the master station
properly via RS-485 communication.
C-ERR LED (Red)
This LED will illuminate when a RS-485
communication error occurs with the
master station.
Communication function
switch
(SW2)
Set the transmission rate, communication
protocol and termination resistor of
RS-485 communication.
Address number setting
switch
(SW3)
This switch set the address number (slave
address) of RS-485 communication.

Installation
Location for installation
The motor and driver are designed and manufactured for installation in
equipment. Install them in a well-ventilated location that provides easy access
for inspection. The location must also satisfy the following conditions:
Inside an enclosure that is installed indoors (provide vent holes)
Operating ambient temperature
Motor: 0 to +40 °C [+32 to 104 °F] (non-freezing)
Driver: 0 to +40 °C [+32 to 104 °F] (non-freezing)
Operating ambient humidity 85% or less (non-condensing)
Area not exposed to direct sun
Area free of excessive amount of dust, iron particles or the like
Area free of excessive salt
Area that is free of explosive atmosphere or toxic gas (such as sulfuric gas)
or liquid
Area not subject to splashing water (rain, water droplets), oil (oil droplets)
or other liquids
Area not subject to continuous vibration or excessive shocks
Area free of excessive electromagnetic noise (from welders, power
machinery, etc.)
Area free of radioactive materials, magnetic elds or vacuum
Altitude Up to 1000 m (3300 ft.) above sea level
