*1: The rush current, which is approx. 5 to 12 times the
rated current, flows for approx. 1 to 2msec after
power-on. Please note that the rush current value
varies depending on the impedance of the power
line.
*2: Excitation phase detection is performed after
power-on. In such a case, the current becomes
maximum (normally 100msec).
However, a current of approx. 6.0A flows (for
approx. 1 to 2msec) if the motor driving power is
turned on again after its shutdown.
*3: Excitation phase detection is performed after
power-on. In such a case, the current becomes
maximum (normally 100msec).
However, a current of approx. 10.0A flows (for
approx. 1 to 2msec) if the motor driving power is
turned on again after its shutdown.
NOTE 1: Position data and parameters are written to EEPROM.
Please note that the rewrite limit is around 100,000 times.

As a +24V DC power supply,
select the power supply of the
"peak load support" specification
or one with sufficient capacity.
In particular, in the case of the
unit with the remote sensing
function, the greatest care is
required.

Do not use this product in the following environment.
 Location where the surrounding air temperature exceeds the range of 0 to 40C
 Location where condensation occurs due to abrupt temperature changes
Location where relative humidity exceeds 85%RH

 Location exposed to corrosive gases or combustible gases
6.0A
 Location exposed to significant amount of dust, salt or iron powder
26.4W
 Location subject to direct vibration or impact
 Location exposed to direct sunlight
Location where the product may come in contact with water, oil or chemical droplets

 Environment that blocks the air vent [Refer to Installation and Noise Elimination
Section]
When using the product in any of the locations specified below, provide a sufficient
shield.
 Location subject to electrostatic noise
 Location where high electrical or magnetic field is present

2. Storage and Preservation Environment
The storage and preservation environment should comply with the same standards as
those for the installation environment. In particular, when the machine is to be stored
for a long time, pay close attention to environmental conditions so that no condensation
forms. Unless specially specified, moisture absorbency protection is not included in the
package when the machine is delivered. In the case that the machine is to be stored
and preserved in an environment where condensation is anticipated, take the
condensation preventive measures from outside of the entire package, or directly after
opening the package.

Class D grounding
(Formerly Class-III grounding:
Grounding resistance at 100 or less)
2. Precautions Regarding Wiring Method
(1) Use a twisted cable for connection to the 24V DC power supply.
(2) Separate signal lines and encoder cables from high-power lines such as the power
wire.
3. Noise Sources and Elimination
Carry out noise elimination measures for
power devices on the same power path
and in the same equipment.
The following are examples of measures
to eliminate noise sources:
(1) AC solenoid valves, magnet
switches and relays
[Measure]
Install a surge killer parallel with
the coil.
(2) DC solenoid valves, magnet
switches and relays
[Measure]
Install a diode parallel with the
coil. Use a DC relay with a built-in
diode.
4. Heat Radiation and Installation
Conduct design and manufacture in consideration of the control box size, controller
layout and cooling in such a way that the temperature around the controller will be 40C
or less.
