Precautions for use
3 Precautions for use
This chapter explains the limitations and other items the user must note when using the motor, power controller.
•Always use the power controller with Oriental Motor’s torque motor.
Check the permitted power controller/motor combinations in “4.4 Names and functions of parts” on p.9.
•If your equipment needs to be able to actuate an emergency stop of the motor, provide
a mechanical function to stop the motor and hold its position.
Once the thermal protector of the motor is actuated (becomes open), output from the power controller will
stop. However, the protective function alone cannot stop the motor immediately. If your equipment needs to
be able to actuate an emergency stop of the motor, provide a mechanical function to stop the motor and hold
its position.
•Do not install an electromagnetic contactor or power relay between the motor and
power controller.
If the direction is switched between forward and reverse using an electromagnetic contactor, etc., the power
controller may be damaged.
•Connect a protective device to the primary power circuit.
Install a protective device between the power supply and inverter to protect the inverter’s primary circuit.
For details on selecting an appropriate protective device for this purpose, refer to the following to select a
protective device.
Circuit breaker or earth leakage breaker
Motor rated voltage Single-phase 100-115 V Single-phase 200-230 V
Ratings of protective device 125 VAC 5 A (quick cuto󰀨 type) 250 VAC 3 A (quick cuto󰀨 type)
If an earth leakage breaker is to be used, use one with a current sensitivity of 10 mA or more.
•Cable size and wiring distance
Use a power cable and motor cable of AWG18 to 14 (0.75 to 2.0 mm2) in size.
The maximum extendable wiring distance between the motor and power controller is 20 m (65.6 ft.). If the
wiring distance between the power controller and motor must exceed 20 m (65.6 ft.), please contact your
nearest Oriental Motor branch or sales oce.
Minimize the length of the signal cable. Also, wire the control lines away from the main circuits, relay
sequence circuits and other high-power circuits of peripherals, in order to prevent induction by peripherals.
•Noise elimination
See “5.5 Conformity to the EMC Directive” on p.12 for measures with regard to external noise.
•Grease measures
On rare occasions, grease may ooze out from the gearhead. If there is a concern over possible environmental
damage resulting from the leakage of grease, provide an oil tray or similar oil catching mechanism in order
not to cause a secondary damage.
Grease leakage may lead to problems in the customer’s equipment or products.

Connecting the main circuit terminals” on p.18.
 Wiring the control cable
Wire each control cable of the power controller over the minimum distance using a shielded cable. For the
applicable cable, refer to “6.4 Connecting the control circuit terminals” on p.19.
 Wiring a shielded cable
Ground each shielded cable using a metal cable
clamp that contacts the entire periphery of the
shielded cable. Install the cable clamp at the tip of
the shielded cable and connect it to an appropriate
grounding point.
Cable clamp
Shielded cable
 Notes about installation and wiring
•Connect the motor directly to their grounding points so as not to generate dierence in grounding electrical
potential between the motor/inverter and control system equipment nearby.
•If a relay or electromagnetic switch is used with the inverter, connect a mainslter or surge absorber to
absorb any surge voltage that may generate from the relay or electromagnetic switch.
•Minimize the wiring length of each cable and do not loop or bundle any extra length.
•Wire the power cables such as the motor cable and power supply cable separately from the control cables,
and keep a minimum distance of 100 mm (3.94 in.) between the two sets of cables. Also keep as much
distance as possible between the AC input cable and output cable of the mains lter.

Note
•As for the DC power supply (+24 V) for the control circuit of the power controller, use a
power supply with overcurrent protection function, or install an overcurrent protection device
(such as a fuse) in the output section. Failure to take these measures may result in re or
equipment damage.
•If the internal power supply is used while the source logic is selected, do not connect
anything to the C2 and C3 terminals. If these terminals are shorted due to miswiring, the
power controller may be damaged.
