Caution


Acceleration (acceleration/
deceleration rate)
The acceleration (acceleration/deceleration rate)
when the actuator is started or stopped must be
within the specified range, irrespective of the
loaded mass.
Operating at an acceleration (acceleration/
deceleration rate) beyond the specified range
may result in a loss of position. Page 21


Operating speed
The operating speed of the actuator must be
within the specified range, including during
acceleration. Page 22


Do not let the screw shaft hit the
stroke end or load
Do not let the screw shaft hit the stroke end or
load during operation, since such an impact may
damage the actuator.
Should the screw shaft hit the stroke end or load,
return the potentiometer for adjusting the motor
operating current (RUN) to the factory-set value
and then retract the shaft by operating it in the
reverse direction at the starting speed.
Page 22


Driver’s heat-sink temperature
When operating the motor, keep the driver’s
heat-sink temperature to 70°C or below. If the
temperature exceeds 70°C, the driver may be
damaged.


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.
Precautions for use
This section covers the limitations and points to
note regarding use of the driver.

10



Use an actuator with
electromagnetic brake for an
application involving up/down
travel.
For a lifter or other device in which the load
moves up and down, use the electromagnetic
brake type and provide an additional safety-brake
mechanism to hold the load in position.
To hold the load in position, apply the
electromagnetic brake only after the motor has
stopped. Repeated braking for such a purpose
will wear the brake hub excessively, causing its
holding ability to drop.


Preventing electrical noise
Take the following anti-noise measures to
prevent malfunction of the driver and actuator
due to external noise.
zz
zz
zConnecting actuator
It is recommended that braided screen cable be
used for connection between the driver and
actuator.
zz
zz
zConnecting I/O cable
zMinimize the length of the I/O cable.
zWire the control I/O cables by maintaining a
minimum distance of 300 mm from the
inductive loads of electromagnetic relays, etc.,
as well as the power lines of the power source,
actuator and the like. Do not wire the control
I/O cables in the same duct or pipe in which
power lines are wired.

zConnecting mains filter
Install a mains filter in the AC input line to the
power transformer in order to prevent the noise
generated within the driver from propagating
outside via the power source for the driver.
Install the mains filter as close to the AC input
terminal of power source for the driver as
possible, and use cable clamps and other means
to secure the input and output cables firmly to
the surface of the enclosure.
Connect the ground terminal of the noise filter
to the grounding point, using as thick and short
a wire as possible.
Do not place the AC input cable (Between
AWG18 (0.75 mm2) and AWG16 (1.25 mm2))
parallel with the mains filter output cable
(Between AWG18 (0.75 mm2) and AWG16
(1.25 mm2)). Parallel placement will reduce
mains filter effectiveness if the enclosure’s
internal noise is directly coupled to the power
supply cable by means of stray
capacitance.

The figure shows the pulse signal’s voltage level.
Pulse-signal waveform
zInput pulse signals should have a
waveform with sharp rise/fall edges,
as shown below.
NOTE
zDo not allow the driver’s temperature to
exceed 70°C, which is the heat-radiating plate’s
saturation temperature during operation.
zThe minimum interval before the rotation
direction is switched will vary, depending on
the operating speed, acceleration, load mass,
thrust, and stiffness of peripheral structure.
zIf a pulse signal is not input, be sure to set the
photocoupler to [OFF]. Otherwise, the driver
can’t shift to the motor standstill current. Do
not input pulse signals to the CW and CCW
inputs simultaneously.
If one input receives a pulse signal while the
other input has its photocoupler turned to [ON],
the motor cannot operate correctly.

Warning
Do not turn the A.W.OFF (All windings off) input
to ON while the actuator is operating. If the
input is turned ON, the actuator will stop and
lose its holding capability. A load may descend,
resulting in injury or equipment damage.
Caution
If the screw shaft must be moved directly by hand
(for manual alignment, etc.), do so after
confirming that the driver’s A.W.OFF (All
windings off) input is ON. Failure to do so may
result in injury.
1. When the A.W.OFF input is turned to [ON],
the driver cuts off the current supply to the
motor and the actuator loses its holding
torque. In this condition, the position of the
screw shaft can be adjusted manually.
2. When the A.W.OFF input is turned to [OFF],
the driver resumes the current supply to the
motor and restores the actuator’s holding
torque.

zC/S (Resolution switching) input
This input is used to select a desired resolution
from the values set with the resolution setting
switches (DATA1, DATA2).
How to set the resolution setting switches
Page 19
Turning the C/S input [ON] changes the
resolution to the setting of the resolution setting
switch DATA2.
Turning the C/S input [OFF] changes the
resolution to the setting of the resolution setting
switch DATA1.
Example: DRL42
zTurning the C/S input [OFF] when DATA1 is
set to 0 (0.004 mm) changes the resolution to
0.004 mm.
zTurning the C/S input [ON] when DATA2 is set
to 6 (0.0004 mm) changes the resolution to
0.0004 mm.

Output signals
All driver output signals are photocoupler/
open-collector outputs.
The signal state indicates the [ON: current
supplied] or [OFF: current not supplied] status
of the internal photocoupler or transistor rather
than the voltage level of the signal.

Motor currents
Set the motor operating current and standstill
current of actuator.
Warning
Do not set the motor operating current and
standstill current too low. The actuator will lose
its holding brake force and the load may drop,
causing injury or equipment damage.
Caution
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 actuator to start
accidentally, resulting in injury or equipment
damage.
