Notice
Please use the cables designated by our Company as far as possible when connecting.
Please confirm the rated current and operating environment of the model when using cables other than those
specified by our Company. Use the wiring materials designated by the Company or equivalent products.
Please tighten the fixing screw and locking mechanism of cable connector.
If the fastening is not sufficient, the cable connector may fall off during operation.
Do not use the same sleeve for high-voltage wires (main loop cables) and low-voltage wires (cables for input and
output signals and encoder cables), nor tie them together. Please keep a spacing of more than 30cm when wiring
when not placing strong and weak current wires into separate bushings.
It will cause misoperation due to interference of weak current wires if it is too close.
Please install the battery on either side of the upper device or encoder cable.
If batteries are installed on the upper device and encoder cable at the same time, a circulation loop will be formed
between the batteries, resulting in product damage or burning.
Pay attention to the polarity when connecting the battery.
Battery rupture can cause encoder failure.

Important
Please use circuit breakers or fuses for wiring to protect the main circuit.
The servo drive is directly connected to a commercial power supply without using transformers or the like for
insulation. To prevent the servo system from being mixed with the outside world, be sure to use circuit breakers
or fuses for wiring.
Please set the leakage breaker.
Servo drive has no built-in ground short circuit protection loop. To build a safer system, please configure the earth
leakage breaker for overload and short circuit protection, or install the earth leakage breaker for short circuit
protection in combination with the circuit breaker for wiring.
Please avoid frequently turning ON/OFF the power supply.
Frequent ON/OFF power supply will lead to aging of internal components of servo drive, so do not frequently
ON/OFF power supply except for necessary applications.
The power ON/OFF interval should be more than 1 hour (roughly standard) after starting the actual operation
(normal operation).
Please observe the following precautions when wiring to use the servo system safely and stably.
Please use standard cables for each connecting cable. In addition, when designing and configuring the
system, please shorten the cable as much as possible.
Please be careful not to bend or tighten it when the core diameter of signal cable is less than
0.3
mm

4.1.2 Anti-interference countermeasures
Important
No anti-radio interference measures have been taken since the servo drive is industrial equipment.
The peripheral equipment may be affected by switching interference since the servo-driven main circuit uses
high-speed switching elements.
Please take anti-interference measures when using near residential buildings or when you are worried about
radio interference.
The servo drive is internally provided with a microprocessor. Therefore, it may be affected by noise from
servo-driven peripheral equipment.
To suppress the noise interference between servo drive and peripheral equipment, the following
anti-interference countermeasures can be taken as required.
Please set the input command equipment and noise filter as close to the servo drive as possible.
Be sure to connect surge absorbers to the coils of relays, solenoid valves and electromagnetic contactors.
Please do not put the following cables into the same sleeve or tie them together. In addition, please keep an
interval of more than 30cm when wiring.
Main loop cable and cable for input and output signals
Main loop cable and encoder cable
Do not use the same power source as electric welding machine, electric spark machine, etc. Even if it is not
the same power supply, when there is a high frequency generator nearby, please connect the noise filter at
the input side of the main loop power cable and the control power cable.
