Precautions for use
7
Installation
z
Grease measures
On rare occasions, grease may ooze out from the gearhead. If there is concern over possible environmental
contamination resulting from the leakage of grease, check for grease stains during regular inspections. Alternatively,
install an oil pan or other device to prevent damage resulting from contamination. Grease leakage may lead to
problems in the user’s equipment or products.
z
When using in low temperature environment
When an ambient temperature is low, a load torque may increase due to the oil seal or viscosity increment of grease
used in the gearhead, and the output torque may decrease or the overload alarm may be generated. However, as time
passes, the oil seal or grease is warmed up, and the motor can be operated without generating the overload alarm.
z
Apply grease to the hollow output shaft of a hollow shaft at gearhead.
When using a hollow shaft at gearhead, apply grease (molybdenum disulde grease, etc.) on the surface of the load
shaft and inner walls of the hollow output shaft to prevent seizure.
Insulation resistance measurement and dielectric strength test
z
Do not conduct the insulation resistance measurement or the 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.
Operations
z
Regeneration energy
When the motor is used in operation such as rapid acceleration/deceleration of an inertia body or vertical drive
(elevating equipment), regeneration energy may generate. Since the driver has no function to consume regeneration
energy, if the output capacity or overvoltage allowance of the DC power supply is small, the protective function for
the power supply or driver may be activated to stop the motor. When performing these operations, use a DC power
supply or battery that has a large output capacity or overvoltage allowance.
If the protective function for the power supply or driver is activated, contact your nearest Oriental Motor sales oce.
z
Use an electromagnetic brake motor in an application of vertical drive such as elevating equipment.
When the motor is used in an application of vertical drive such as elevating equipment (lifting and lowering device),
use an electromagnetic brake motor so that the load can be held in position.
z
The electromagnetic brake of the motor is used for holding the motor shaft. Actuating the
electromagnetic brake to hold the motor shaft while the motor is rotating may result in damage to
equipment.
z
Rotation direction of the gearhead output shaft
Combination type-parallel shaft gearhead
The rotation direction of the gearhead output shaft may vary with that of the motor output shaft depending on the
gear ratio of the gearhead.
Gear ratio Rotation direction of the gearhead output shaft
10
,
15
,
20
Same direction as the motor output shaft
30
,
50
,
100
* Opposite direction to the motor output shaft
* Same direction as the motor output shaft when the gear ratio is 100 for the 200 W type
