1. Precautions
1．1 PrecautionsforInstallation
●Do not use in a place where there is flammable gas and/or corrosive gas.
●Motors and Drivers for use only in equipment of protection class Ⅰ.
●The motor housing must be mounted with a screw and spring washer to the ground point of the equipment.
●When installing the motor into your equipment, ensure that the motor cable is fixed and do not move.
In addition, do not apply any pressure to these cable.
●Installation must be performed by a qualified installer.
●Do not rework or modify the motor cable and extension cable (sold separately). Do not remove the sheath of the cable and
then ground or touch the shielded wire. This may cause electric shock or trigger the ground fault interrupt circuit.
1．2 PrecautionsforOperation
●The enclosure temperature of this motor can exceed 70℃(depending on operation conditions). In case
motor is accessible during operation, please attach the following warning label so that it is clearly visible.
Warning label
●Always turn off the power to the motor before conducting checks or performing work on the motor.
1．3 PrecautionsforTroubleshooting
●Refer to Chapter8 for Troubleshooting when the motor and driver had in correct operation. If the trouble could not be
recovered, please contact your nearest ORIENTAL MOTOR office (refer to rear cover for the contact)
Do not disassemble the motor and driver.

Note Clean any dirt off the pilot section of the motor and gearhead.
Insufficient cleaning may cause incomplete attachment and leaking of grease within the gearhead.
Don't pinch the O-ring when assembling the motor and gearhead.
(4) Installing on Other Devices

■Mounting dimensions
Base mounting Back mounting
Note ・When mounting the driver directly on a surface without using the mounting brackets, be sure to use screws of
suitable length. If the screws are too long, they could make contact with the driver's internal circuits and damage
the driver. (Use mounting screws that extend no further than 3mm from the surface of the driver into the driver.)
・To improve ventilation, mount the driver in an upright position as shown in the figures above.
・When mounting the driver in a tightly close up place like the control panel and a place where there is a heating
hearby , be sure to when the driver ambient timperature exceeds 40℃, cool the driver with a fan.
・The back mount brackets are asymmetry up and down snd they can be used at any direction.
・The size * in the diagram vary depending on the direction fo the mounting plate. In the reverse direction it is 19mm
long.

Note The temperature of the motor's casing and the driver's rear panel should not exceed 90℃and 80℃, respectively.
If the driver's internal heat sink exceeds 90℃, the overheat protection function will be activated,
causing the motor to stop.

Action
Activated when a load exceeding the rated torque
(load torque or motor current of 130% max. of rated
load or rated motor current) is applied to the motor for
5 seconds or more or when the motor is operated in
short cycles of stopping/starting or CW/CCW rotation.
Activated when the driver's ambient temperature
exceeds 50 , or when its internal heat sink exceeds
90 as a result of using short operating cycles of
starting/stopping or CW/CCW rotation.
Protects the driver against damage when the motor
is driving an inertial load exceeding the permissible
inertial load, or when the motor shaft is turned by the
load (during lowering operation).
Activated when a input voltage to the driver is less
than specified voltage.
Prevents motor malfunction when the sensor cable
within the motor cable is disconnected during motor
operation. (An alarm signal will not be output while
the motor is at a standstill.)
Activated when motor speed falls considerably below
the speed control range (less than 250r/min) due to
a reduction in the speed setting, an overload, etc.

Response
Check the load torque, referring to the load torque-
driver input current characteristics on page 21.
Reduce the load torque if it seems to exceed the
rated torque, or lengthen the operating cycle.
If the driver's ambient temperature exceeds 50 ,
employ some cooling method to lower it; otherwise,
reduce the load torque or lengthen the operation
cycle.
Check to see that the inertial load does not exceed
the permissible value (see Catalogue) or that the
motor shaft is not being turned by the load.
Check to see that there is input voltage to the
driver.
Check to see that the motor cable has not been
disconnected.
Increase the speed setting to 300r/min or higher.
This function is not activated by an overload if
speed is above 300r/min.

potentiometer.
(1) Using a DC Power Supply
Note ・Use a DC power supply whose current capacity is equal to or greater than the value obtained by the following
expression:
I = 1×N [mA]
where N is the number of drivers.
Thus, when two drivers are used, current capacity should be at least 2mA.
・The lines for other input/output signals should be connected to each driver individually.
・Motor speed differences can be adjusted by connecting a resistance of 470Ω, 1/4W to the M terminal of the
first driver, and a 1kΩ, 1/4W variable resistor (VRn) to the M terminals of the other drivers.
(2) Using the External Speed Potentiometer
Note ・Connect the control line to the H, M and L terminals of each driver.
・The resistance of the speed set potentiometer is given by the following expression:
VRx = 20/N [kΩ], N/4 (W)
where N is the number of drivers.
Thus, if two drivers are used, the resistance is 10kΩ, 1/2W.
・Connect the other input/output lines to each driver individually.
・Motor speed differences can be adjusted by connecting a resistance of 470Ω, 1/4W to the M terminal of the
first driver, and a 1kΩ, 1/4W variable resistor (VRn) to the M terminals of the other drivers.
・No more than 20 motors should be operated simultaneously when using the external speed potentiometer.
