Precautions for use
This chapter covers limitations and requirements the user should consider
when using the product.
Be sure to match the motor output power with the driver output power.
Wiring
zConnecting the motor and driver
To connect the motor and driver, always use the dedicated connection cable
(sold separately). With electromagnetic brake motors, use the dedicated
connection cable (sold separately) that a label for electromagnetic brake motor
is attached. Limit the number of times so that attaching/detaching between
the connection cable and the motor or driver will not exceed 100times.
zConnection cable
Do not apply a strong force on the locking lever of the connector for motor
connection. Applying a strong force on the locking lever may cause damage.
Refer to p.6 for details.
Installation circumstances
zGrease 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.
zNote when using in 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 the overload alarm may be generated. However, as
time passes, the oil seal or grease is warmed up, and the motor can be driven
without generating an overload alarm.
zApply grease to the hollow output shaft of a hollow shaft
at gearhead
Apply grease (molybdenum disulde grease, etc.) on the surface of the
loadshaft and inner walls of the hollow output shaft to prevent seizure.
Insulation resistance measurement and dielectric strength test
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.
Operations
zUse the electromagnetic brake motor in an application of
vertical drive such as elevating equipment
When the motor is used in vertical drive such as elevating equipment (lifting
and lowering device), use an electromagnetic brake motor so that the load can
be held in position.
zRotation direction of the gearhead output shaft
The rotation directions of the gearhead output shaft relative to the motor
output shaft are as shown in the gures below.
Check the operating manual included with the driver for the rotation direction
of the gearhead output shaft relative to the operation input signals of the
driver.
