• Keep the driver’s input power voltage within the specified range to avoid fire and
electric shock.
• For the driver’s power supply use a DC power supply with reinforced insulation
on its primary and secondary sides. Failure to do so may result in electric shock.
• The digital I/O part does not have reinforced insulation. For the digital I/O, use a
DC power supply with reinforced insulation provided on the primary and
secondary sides. Failure to do so may result in electric shock.
• Connect the cables securely according to the wiring diagram in order to prevent
fire.
• Do not forcibly bend, pull or pinch the cable. Doing so may fire.

2 Safety precautions
−6−
Operation
• Turn off the driver power in the event of a power failure, or the motor may
suddenly start when the power is restored and may cause injury or damage to
equipment.
• Do not turn the C.OFF (all windings off) input to “ON” while the motor is
operating. The motor will stop and lose its holding ability, which may result in
injury or damage to equipment.
Repair, disassembly and modification
• Do not disassemble or modify the motor or driver. This may cause fire, electric
shock or injury.
Caution
General
• Do not use the motor and driver beyond their specifications, or injury or damage
to equipment may result.
• Keep your fingers and objects out of the openings in the motor and driver, or fire
or injury.
• Do not touch the motor or driver during operation or immediately after stopping.
The surfaces are hot and may cause a burn.
• If the power supply cable or motor cable connected the driver are forcibly bent or
pulled, the driver will receive stress and may suffer damage.
Transportation
• Do not hold the motor output shaft or motor cable. This may cause injury.
Installation
• Keep the area around the motor and driver free of combustible materials in order
to prevent fire or a burn.
• To prevent the risk of damage to equipment, leave nothing around the motor and
driver that would obstruct ventilation.
• Provide a cover over the rotating parts (output shaft) of the motor to prevent
injury.
Operation
• Use a motor and driver only in the specified combination. An incorrect
combination may cause a fire.
• 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.
• Before supplying power to the driver, turn all control inputs to the driver to
“OFF.” Otherwise, the motor may start suddenly and cause injury or damage to
equipment.
• Before moving the motor directly (as in the case of manual positioning), confirm
that the driver C.OFF (all windings off) input is “ON” to prevent injury.

2 Safety precautions
−7−
• To prevent bodily injury, do not touch the rotating parts (output shaft) of the motor
during operation.
• Immediately when trouble has occurred, stop running and turn off the driver
power. Failure to do so may result in fire, electric shock or injury.
Disposal
• To dispose of the motor or driver, disassemble it into parts and components as
much as possible and dispose of individual parts/components as industrial waste.

3 Precautions for use
−8−
3 Precautions for use
This section covers limitations and requirements the user should consider when
using the CSK series.
• Do not apply an overhung load and thrust load in excess of the
specified permissible limit.
Be sure to operate the motor within the specified permissible limit of overhung load
and thrust load. Operating it under an excessive overhung load and thrust load may
damage the motor bearings (ball bearings). See page 18 for details.
• Motor case temperature
When operating the motor, keep the motor’s case temperature to 100 °C (212 °F) or
below. If that temperature exceeds 100 °C (212 °F) 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 heatsink temperature
When operating the motor, keep the driver’s heatsink temperature to 80 °C (176 °F)
or below. If the temperature exceeds 80 °C (176 °F), 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.
• Conduct the insulation resistance measurement or withstand voltage
test separately on the motor and the driver.
Conducting the insulation resistance measurement or withstand voltage test with the
motor and driver connected may result in injury or damage to equipment.
• Preventing electrical noise
See 5.6 ”Installing and wiring in compliance with EMC Directive” on page 20 for
measures with regard to noise.
• Check the colors of motor leads and connect them correctly and
securely.
Wrong connection of leads or poor contact may damage the driver.
• Regeneration
When a large inertial load is operated at high speed, regenerative energy will
generate and increase the power supply voltage, which can damage the driver.
Review the operating condition and make sure regenerative voltage will not
generate.

3 Precautions for use
−9−
• 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%. (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% while
the motor is at a standstill. Therefore, when selecting a motor consider the reduced
holding torque at motor standstill of around 40% of the maximum static torque at
excitation.
• Geared type motors
Allowable torque
Operate the motor by making sure the sum of the acceleration/deceleration torque at
the starting/stopping of the motor and the load (friction) torque doesn’t exceed the
allowable torque. Operating the motor in excess of the allowable torque may result
in a damaged gear.
Allowable speed range
Operate the motor at speeds within the allowable range.
Operating the motor at a speed outside the allowable range may result in a shorter
gear life.
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 type and gear ratio.
Gear ratio Rotating direction
3.6:1, 7.2:1, 9:1, 10:1 Same direction
18:1, 36:1 Opposite direction
Grease of 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
pen or other device to prevent leakage from causing further damage. Oil leakage
may lead to problems in the customer’s equipment or products.

5.6 Installing and wiring in compliance with EMC
Directive
Effective measures must be taken against the EMI that the CSK series may give to
adjacent control-system equipment, as well as the EMS of the CSK series itself, in
order to prevent a serious functional impediment in the machinery. The use of the
following installation and wiring methods will enable the CSK series to be
compliant with the EMC Directive (the aforementioned compliance standards).
The compliance of the final machinery with the EMC Directive will depend on such
factors as the configuration, wiring, layout and risk involved in the control-system
equipment and electrical parts. It therefore must be verified through EMC measures
by the customer of the machinery.
