*1 For single phase/three phase 200 V common specifications, select peripheral equipment according to the power supply used.
*2 The electromagnetic contactor used for the external dynamic brake resistor should have the same rating as the electromagnetic contactor used for the main circuit.
*3 Use the same crimp terminal for the ground screw as the crimp terminal for the main circuit terminal block.
*4 Make sure that the thickness of the ground wire and the external dynamic brake resistor wire are the same or larger than the motor wire.
*5 For UL certification, in the case of a single phase power supply, please use a clamp meter that can measure the effective value current and derate the input effective current to 12A or less.
*6 Applicable wire size varies depending on the motor model number. Please check the instruction manual or specifications document for the applicable wire size for each motor model number.
* Specifications are subject to change due to improvements, etc. Please be sure to obtain the latest information when using these products.
● Circuit breakers and electromagnetic contactors
To comply with EU directives/UK standards, be sure to connect an IEC standard and UL certified (LISTED, marked) molded circuit breaker between the power supply and the noise filter.
Make sure that the short-circuit current of the power supply you use is less than 5000 Arms symmetrical current when the product’s maximum input voltage is less than that. If the short-circuit current of the power supply exceeds this, install a currentlimiting device (current-limiting fuse, current-limiting breaker, transformer, etc.) to limit the short-circuit current.
<Caution>
• Select a molded circuit breaker and noise filter with a capacity commensurate with the power supply capacity (taking load conditions into consideration).
● Terminal block and protective ground terminal
• Use copper conductor wires with a temperature rating of 75 °C or higher for wiring.
• For frames A to D, use the included dedicated connectors. In that case, keep the length of the stripped wire between 8 mm and 9 mm.

<Caution>
• Exceeding the maximum tightening torque may cause damage.
• Do not turn on the power while the terminal block screws are loose.
• Turning the power on while the screws are loose may cause smoke or fire.
<Remarks>
• Check the tightening torque periodically once a year for looseness.

Safety function
Connector X3 connection
A safety circuit that controls safety functions is made by connecting the host controller. If you do not want to construct a safety circuit, please use the included safety bypass plug.
Safety Torque Off (STO) Function Overview
The Safe Torque Off (STO) function uses a safety input signal to forcibly turn off the drive signal of the power transistor inside the servo driver using a circuit (hardware) to cut off the motor current and output torque.
When the STO function is activated, the servo driver turns off the servo ready output signal (S-RDY) and enters the STO state, and "St" is displayed on the front panel. Also, when the STO input is released and the Servo-On input is turned off (OFF), the state automatically transitions to the Servo-Off state.
Safety precautions
- If there is an external force (such as gravity on a vertical axis), the motor will move. If holding is required, use a separate external brake or other means. Please note that the brake of a servo motor with a brake is only for holding and cannot be used for braking purposes.
- Furthermore, even if there is no external force, if parameter Pr5.10 "Sequence at alarm" is set to free run (dynamic brake disabled), the motor will free run and the stopping distance will be longer. Please do not let this become a problem.
- Even when the STO function is working, the following dangers still exist, so be sure to consider safety in your risk assessment. Incorrect use may result in personal injury.
- If there is an external force (such as gravity on a vertical axis), the motor will move. If holding is required, use a separate external brake or other means. Please note that the brake of a servo motor with a brake is only for holding and cannot be used for braking purposes.
- Due to a power transistor failure, etc., the motor may move within a range of up to 180 electrical degrees. Please do not let this become a problem.
- The STO function cuts off power to the motor, but does not cut off power to the servo driver and does not provide electrical isolation. When performing maintenance on the servo driver, take other measures such as cutting off the power to the servo driver.
- EDM output signals are not safety outputs. Do not use it for any purpose other than the failure monitoring function. Incorrect use may result in personal injury.
- The STO status monitor output signal is not a safety-related part. When designing the system, make sure to avoid dangerous conditions even if the STO condition monitor output signal cannot be output normally. Incorrect use may result in personal injury.
- The dynamic brake and external brake release signal outputs are not safety-related parts. Make sure that the system design avoids dangerous conditions even if the external brake release fails during STO conditions. Incorrect use may result in personal injury.
- When using the STO function, connect equipment that complies with safety standards. Use of equipment that does not meet safety standards may result in personal injury.
