1. Safety Information
 Safety accidents and damage to the product may occur, so be sure to read the safety
instructions before use and use it correctly.
⚠ Warnings
- 전원이 켜진 상태에서 서보 드라이브 주 전원을 연결/분리하지 마십시오.
Do not connect/disconnect the main power of the servo drive while the power is on.
- 전원이 켜진 상태에서 서보 드라이브 엔코더 케이블 및 I/O를 연결/분리하지 마십시오.
모터 및 서보 드라이브의 고장 원인이 될 수 있습니다.
Do not connect/disconnect the servo drive encoder cable and I/O while the power is
on. Motor and servo drive may be damaged.
- 전원 케이블은 모터가 움직이지 않을 때도 고전압을 전달할 수 있습니다.
The power cable can carry high voltage even when the motor is not moving.
- 서보 드라이브의 메인 전원은 드라이브 사양에 맞춰 정확히 입력되어야 합니다.
드라이브 파손 및 고장의 원인이 될 수 있습니다.
The main power of the servo drive must be accurately input according to the drive
specifications. It may cause damage to the drive
- 서보 드라이브 U, V, W 출력 단자에 전원을 직접 접속하지 마십시오.
Do not connect power directly to the servo drive U, V, W output terminals.
- 서보 드라이브 전원을 차단 한 후 캐패시터가 완전히 방전된 후 전원을 분리해 주십시
오.
After turning off the servo drive power, disconnect the power after the capacitor is
completely discharged.

⚠ Cautions
- U, V, W 케이블과 Encoder 케이블은 반드시 분리하여 배선해 주십시오.
Be sure to separate U, V, W cables and encoder cables before wiring.
- 전원 차단 후 U, V, W 케이블과 Encoder 케이블 배선작업을 진행하십시오.
After turning off the power, proceed with wiring the U, V, W cables and encoder cables.
- 떨어뜨리거나 강한 충격을 가하지 마십시오.
Do not drop it or subject it to strong impact.
- 가연성 물질, 물 근처는 설치를 하지 말아주십시오.
Do not install near flammable substances or water.
- 서보 드라이브 내부에 피복이나 구리선 등이 들어가지 않도록 해 주십시오.
Make sure that no sheath or copper wire gets inside the servo drive.
- Encoder 케이블은 쉴드 케이블 사용을 권장합니다.
It is recommended to use shielded cables for encoder cables.
- EtherCat 케이블은 CAT.7 이상의 케이블 사용을 권장합니다.
For EtherCat cables, it is recommended to use CAT.7 cables.
- 초기 전원 투입 전 모터의 U, V, W 및 Encoder 케이블 등을 확인하여 주십시오.
Check the U, V, W and encoder cables of the motor before turning on the power.
- 노이즈 방지를 위해 Encoder 케이블 및 U, V, W 및 전원 FG 접속을 권장합니다.
It is recommended to connect the encoder cable and U, V, W and power FG to prevent
noise.
