11
●
Turn off the driver power in the event of a power
failure, otherwise the motor may suddenly start
when the power is restored and may cause
injury or damage to equipment.
●
Do not turn the C.OFF (current-off) input to ON
while the motor is operating. If the input is
turned ON, the motor will stop and lose its
holding capability, causing possible injury or
equipment damage.
●
Do not repair, disassemble or modify the driver.
Doing so may result in fire or injury.
●
Do not use the motor and driver beyond their
specifications. Doing so may result in injury or
equipment damage.
●
Do not touch the motor or driver’s heat sink
while the driver is conducting current. Doing so
may result in burns.
●
Do not hold the motor by the output shaft or
cable. Doing so may result in injury.
●
Use the motor and driver only in the specified
combination. Failure to do so may result in fire
or equipment damage.
●
Provide an emergency-stop device or
emergency-stop circuit external to the equipment
so that the entire equipment will operate safely
in the event of a system failure or malfunction.
Failure to do so may result in injury.
●
Turn on the power to the driver after making sure
all control inputs of the driver are turned OFF.
Failure to do so may cause the motor to start
accidentally, resulting in injury or equipment
damage.
●
If the motor’s output shaft must be moved
directly by hand (for manual alignment, etc.), do
so after confirming that the driver’s C.OFF
(current-off) input is ON. Failure to do so may
result in injury.
●
Do not touch the rotating part of the motor
(output shaft) during operation. Doing so may
result in injury.

Installation

● About grease of the geared motor
On rare occasions, a small amount of grease
may ooze out from the geared motor. 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.
● Maximum static torque at excitation
The maximum static torque at excitation
represents the torque when the motor is excited
at the rated current. If the motor is combined
with a dedicated driver, the automatic current-
cutback function reduces the maximum static
torque at excitation to around 40 percent. (The
specific value varies, depending on the motor
standstill current that is set.)
Once started, the
motor can be accelerated or operated at the
maximum static torque at excitation. However,
the holding torque drops to around 40 percent
while the motor is at a standstill. Therefore,
when selecting a motor consider the reduced
holding torque at motor standstill of around 40
percent of the maximum static torque at
excitation.
● Driver connectors
Always use the supplied connectors for
connecting the power supply, I /O signals and
motor to the driver. When crimp-fitting the leads
to the contact, secure a strong connection using
a crimping tool as specified by the connector
manufacturer. Oriental Motor does not supply
crimping tools.
12
● Overhung load
Always operate the motor within the allowable
overhung load.
Continuing to operate the motor under an
overhung load exceeding the allowable value
may damage the motor bearing or output shaft.
● Motor case temperature
When operating the motor, keep the motor’s
case temperature to 100°C or below.
If that temperature exceeds 100°C due to
operating conditions (ambient temperature,
operating speed, duty, etc.), the motor coil may
be burned or the life of the bearing shortened.
● Driver’s heat-sink temperature
When operating the motor, keep the driver’s
heat-sink temperature to 80°C or below.
If the temperature exceeds 80°C, the driver may
be damaged.
● Provide a measure to retain the position
of the equipment’s movable part when
this unit is used in an vertical application
The motor loses its holding-brake force when
the power is cut off. Therefore, provide a
measure to retain the position of the
equipment’s movable part when this unit is used
in an vertical application such as a lifter.
● Measure insulation resistance or conduct
a dielectric-strength test on your product
alone
Measuring insulation resistance or conducting
dielectric-strength test with the motor and driver
connected may damage your product.
This section covers the limitations and points to note regarding use of the
CSK Series.

● Backlash
The gear output shaft is subject to backlash of
1° to 2°. Backlash refers to the looseness at
the gear output shaft, as generated when the
input side of the gear is fixed.
To reduce the effect of backlash, perform
positioning operations from one direction only-
either from the CW direction or the CCW
direction.
● Rotating direction of the gear output
shaft
The relationship between the rotating direction
of the motor shaft and that of the gear output
shaft changes as follows, depending on the
gear ratio.
● Connector installation /removal
When removing the motor cable of High torque
type and CSK22SG , pull it out horizontally
toward the output shaft.
The motor may be damaged if force is applied
in any other direction.
The optional motor cable for the CSK23P and
CSK24P types employs a connector with a
lock. When removing this type of cable, release
the connector lock first.
Forcibly pulling out the cable without releasing
the connector lock may damage the motor.
Pull out the cable horizontally.
Release the rock.

Installing a load
When installing a load to the motor, align the
centerlines of the motor’s output shaft and load
shaft.
An optional flexible coupling (sold separately) may
be used.
● Direct connection via a coupling
The centerline of the motor’s output shaft and that
of the load shaft must form a single line.
● Belt connection
The motor’s output shaft and load shaft must be
parallel with each other, with the shafts forming
right angles with the line connecting the centers of
two pulleys.
● Gear connection
The motor’s output shaft and gear shaft must be
parallel with each other, with the gear teeth
engaging correctly.
●
When connecting the motor’s output shaft with a
load, pay attention to the center alignment, belt
tension, parallelism of the pulleys, etc. Securely
tighten the coupling and pulley-tightening
screws.
●
Use caution so as not to damage the output
shaft or bearing when installing a coupling or
pulleys to the motor’s output shaft.
●
Do not modify or machine the motor’s output
shaft. Doing so may damage the bearing,
resulting in a failed motor.

Overhung load and thrust load
The overhung load and thrust load on the motor’s
output shaft or gear output shaft must not exceed
the allowable values listed below.
If the overhung load or thrust load has exceed the allowable values, the motor bearing
or output shaft may undergo fatigue failure due to repeated applications of load.

Installing and wiring in compliance with the EMC Directive
Effective measures must be taken with regard to EMI (electromagnetic interference) caused by the CSK
Series motor and/or driver in the control-system equipment operating nearby and EMS ( electromagnetic
susceptibility) of the CSK Series motor and/or driver. Failure to do so may result in serious impairment
of the machine’s functionality.
Oriental Motor conducts EMC measurement of its CSK Series motors and drivers in accordance with
“Installing and wiring for EMC measurement ” on page 21.
The user is responsible for ensuring the machine’s compliance with the EMC Directive, based on the
installation and wiring explained below.

■ Power source
The CSK Series products are specifically designed for DC power source input.
Use a DC power source compliant with the EMC Directive.
■ Mains filter
Connect a mains filter on the input side of the transformer so as to prevent the noise generated in the
driver from being transmitted externally via the power supply line.
Oriental Motor recommends the following mains filters based on the results of internal testing:
●
Install the mains filter as close to the AC input terminal of the DC power source as possible. Also,
secure the input/output cables using cable clamps or the like so that the cables won’t lift from the
surface of the enclosure panel.
●
Connect the ground terminal of the mains filter to the ground point over the shortest distance using a
cable of the largest possible size.
●
Do not wire the AC input cable (AWG18: 0.75 mm2) and the output cable of the mains filter (AWG18:
0.75 mm2) in parallel. If these two cables are wired in parallel, noise inside the enclosure will be
connected to the power supply cable via stray capacitance, reducing the effect of the mains filter.
