Precautions for use
Be sure to match the motor output power with the driver output power.
zConnecting the motor and driver
Use an accessory connection cable (sold separately) when extending the wiring
distance between the motor and the driver.
zGrease measures
On rare occasions, grease may ooze out from the gearhead. If there is concern over
possible environmental damage resulting from the leakage of grease, check for
grease stains during regular inspections. Alternatively, install an oil pan or other
device to prevent leakage from causing further damage. Oil leakage may lead to
problems in the customer’s equipment or products.
zCaution when using under low temperature environment
When an ambient temperature is low, since the load torque may increase by the oil
seal or viscosity increment of grease used in the gearhead, the output torque may
decrease or an overload alarm may generate. However, as time passes, the oil seal or
grease is warmed up, and the motor can be driven without generating an overload
alarm.
zDo not conduct the insulation resistance measurement or dielectric
strength test with the motor and driver connected
Conducting the insulation resistance measurement or dielectric strength test with
the motor and driver connected may result in damage to the product.
zRotation direction of gearhead output shaft
In the case of the combination type-parallel shaft gearhead, the rotation direction of
the gearhead output shaft may dier from that of the motor output shaft depending
on the gear ratio of the gearhead.
Gear ratio Rotation direction of gearhead output shaft
5, 10, 15, 20, 200 Same as the motor output shaft
30, 50, 100∗Opposite to the motor output shaft
