Warning label
Precautions for use
This section covers restrictions and requirements the user should consider
when using the product.
•Thrust
Always operate the cylinder under a load not exceeding the thrust. Operating
the cylinder under a load beyond the thrust or allowing the ball screw to
remain locked may cause damage to the bearings (ball bearings) of the motor.
When using the cylinder in elevating applications, operate it under a load not
applying an external force and not exceeding the maximum transportable
mass in vertical direction.
•Permissible moment
Always operate the cylinder under a moment within the permissible value.
Continuing to operate the cylinder under a moment exceeding the
permissible value may cause malfunction or shorter service life of the cylinder.
•Do not hit the ball screw against an object to stop.
Hitting the operating ball screw against
an object to stop may cause damage
to the cylinder due to an impact. When
operating the cylinders, always provide
a stroke-end detection sensor or limit
sensor in order to prevent the ball screw
from hitting the stroke end or load. If it
is hit to stop, remove a load and return
the ball screw at the recommended
starting speed.

DRLM60 4 0.8
•Do not move the position of the stopper.
The stopper is used to prevent the ball screw from retracting completely into
the motor. Moving the position of the stopper may cause damage to the ball
screw, resulting in cylinder malfunction or damage.
•Do not remove the joint from the ball screw.
Removing the joint causes the installation accuracy of the ball screw to
decrease, resulting in malfunction.
•Take measures to keep the moving part in position if the cylinder
is used in vertical drive such as elevating equipment.
The cylinder loses its holding force upon the occurrence of a power failure
or when the A.W.OFF (all windings o) input is turned ON. Take measures to
keep the moving part in position if the cylinder is used in vertical drive such
as elevating equipment.
•Motor surface temperature
Use the cylinder in conditions where the motor surface temperature dose not
exceed 90 °C (194 °F).
If the motor surface temperature exceeds 90 °C (194 °F) due to operating
conditions (ambient temperature, operating speed, operating duty, etc.), a
damaged motor coil or shorter service life of the bearing (ball bearing) may
result.
•Grease on ball screw
Grease on the ball screw may darken slightly within a short time after the
start of operation. This is not a problem if there is no abnormal noise (i.e., from
deection or interference). Wipe o the dirty grease with a soft cloth, and
apply new grease.
When grease on the ball screw has darkened after the initial operation,
the installation accuracy may be decreased. Refer to p.9 and check the
installation accuracy of the ball screw. When grease was darkened, refer to
p.14 and apply new grease.
•When conducting the insulation resistance measurement or
the dielectric strength test, be sure to separate the connection
between the cylinder and the driver.
Conducting the insulation resistance measurement or dielectric strength test
with the cylinder and driver connected may result in damage to the product.
•Non-guide type cylinder
Provide an anti-spin mechanism for the ball screw
The non-guide type cylinders cannot be operated without an anti-spin
mechanism for the ball screw because the ball screw rotates idly. Always
provide an anti-spin mechanism externally to the cylinder. In addition, make
sure the load installed to the ball screw is supported with a linear guide, etc.
Load to the ball screw
Applying a moment load to the ball screw may cause deterioration of the
ball screw. Support a load with a linear guide etc. and install the load in the
specied installation accuracy so that a moment load does not apply to the
ball screw. Refer to p.9 for the installation accuracy.
Installation accuracy
When using the non-guide type cylinders, always install within the specied
installation accuracy. Low accuracy of installation may result in a malfunction
or shorter service life of the cylinder. Refer to p.9 for the installation
accuracy.
When a carrier guide for load is provided
When a carrier guide for load is provided, always use the non-guide type
cylinders. (Do not use the guide type or table type cylinders.)
•Guide type cylinder, table type cylinder
The guide type and table type cylinders can receive a moment using the load
mounting holes in the joint. Use the cylinders under a moment within the
permissible value.

3
•Electromagnetic brake
Use an electromagnetic brake type cylinder in vertical drive such
as elevating equipment
For vertical drive such as elevating equipment etc., provide a safety brake
mechanism in addition to using an electromagnetic brake type cylinder to
hold the load position. When using the electromagnetic brake to hold the load
position, operate it after the cylinder operation has stopped. If decelerating
and stopping of the cylinder is repeated using the electromagnetic brake,
the brake hub of the electromagnetic brake will wear signicantly and the
braking force will drop.
Connecting an electromagnetic brake
The electromagnetic brake operates via the ON/OFF status of the DC power
supply. When connecting the electromagnetic brake lead wires, observe
the correct polarity. Be sure to connect the included varistor (non-polar) to
protect the contact of the switch or to prevent electrical noise.
•Adjusting knob
Use the adjusting knob to adjust the position manually when the power is
o. Do not touch the adjusting knob when the cylinder is operating. Doing so
may cause the cylinder to malfunction or damage.
zNotes when the connection cable is used
•When inserting the connector
Hold the connector main body, and insert it
in straight securely. Inserting the connector
in an inclined state may result in damage to
connector or a connection failure.
•When pulling out the connector
Hold the connector main body, and pull o
in straight. Pulling out the connector with
holding the lead wire may result in damage
to the connector.
Secure the lead wires at the connection part of the connector to prevent
the connector or terminals from receiving stress due to bending or self-
weight of lead wires. Also, do not excessively bend the lead wires near
the connection part of the connector. Applying stress on the lead wires
may cause poor contact or disconnection, leading to malfunction or
heat generation.

Installing a load
When transporting the equipment in which the cylinder is installed, be
sure to remove the load from the ball screw.
zNon-guide type cylinder
The non-guide type cylinders cannot be operated without an anti-spin
mechanism for the ball screw because the ball screw rotates idly. Refer
to p.9 and be sure to provide an anti-spin mechanism externally to
the cylinder. In addition, make sure the load installed to the ball screw is
supported with a linear guide, etc.
•Installation method
1. Retract the ball screw until it stops at the stopper.
2. Holding the at section of the ball screw with a wrench, secure the load
with a screw (or nut, in the case of the DRLM20 and DRLM28).

•Notes when installing a load
The guide type cylinders can receive a moment. Be sure to use the cylinder
within the specied values in the table. Continuing to operate the cylinder in
a state where a moment exceeding a value in the table is applied may cause
malfunction or shorter service life of the cylinder.
If the ball screw is required to move when installing a load to the
electromagnetic brake type cylinder, refer to p.11 and connect the lead
wires of the electromagnetic brake to the power supply. When the power
supply is turned on, the electromagnetic brake is released, and the moving
part of the cylinder can be moved by hand.

sensor detection or cause the shielding plate to contact the sensor
and result in sensor damage.
yWhen installing the sensor plate and shielding plate to the cylinder,
be sure to use the included screws.
yInstall the sensor so as not to contact with the shielding plate.
zSensor wire connection
Use output signals of the sensor at 5 to 24 VDC, 50 mA or less. If the current
value exceeds 50 mA, connect an external resistor R.
Output operation can be selected from either ON when light is shielded or
ON when light is induced. Use either one of them as appropriate.

Connecting the electromagnetic brake
The electromagnetic brake operates via the ON/OFF status of the DC power
supply. For exclusive use of the electromagnetic brake, provide a power
supply of 24 VDC±5 % 0.08 A or more for the DRLM42, or that of 24 VDC
±5 % 0.25 A or more for the DRLM60. Use a shielded cable of AWG24
(0.2 mm2) or more in diameter to connect the electromagnetic brake to the
DC power supply, keeping the length as short as possible.
zConnecting power supply for the electromagnetic brake
Connect the two lead wires [600 mm (24 in.)] from the cylinder to the DC
power supply.
1. Connect the red/white lead wire to the +24 V terminal of the DC power
supply.
2. Connect the black/white lead wire to the GND terminal of the DC power
supply.
3. Connect the included varistor in parallel across the +24 V and GND
terminals of the DC power supply.

yDo not apply the voltage beyond its specications. Doing so may
increase heat generation in the electromagnetic brake, resulting in
damage to the cylinder. Conversely, insucient voltage may prevent
the brake from releasing.
yBe sure to connect the varistor to protect the contact of the switch or
to prevent electrical noise.
yConnect the lead wires of the electromagnetic brake in the correct
polarities since they have polarities. Connecting the lead wires with
their polarities reversed will not properly operate the electromagnetic
brake.
yProvide separate power supplies for the I/O signals and the
electromagnetic brake.
