5.1 SERVOPACK Main Circuit Wire Size
1. Wire sizes were selected for three cables per bundle at 40 °C surrounding air temperature with the rated
current.
2. Use cable with a minimum withstand voltage of 600 V for main circuits.
3. If cables are bundled in PVC or metal ducts, consider the reduction ratio of the allowable current.
4. Use heat-resistant cables under high surrounding air or panel temperatures where normal vinyl cables
will rapidly deteriorate.
5. Use cables within the allowable moment of inertia.
6. Do not use cables under continuous regenerative state.
5.1.1 Wiring Cables to Main Circuit Terminals
Use the following UL-certified copper cables (rated 75 °C, 600 V) and round crimped terminals (UL standard
compliant) when connecting cables to main circuit terminals. Crimp the terminal with the recommended crimp-
ing tool. Yaskawa recommends the crimped terminals manufactured by J.S.T. Mfg. Co., Ltd.
