3.7 SERVOPACK Main Circuit Wire Size
Cable Types
• Wire sizes are selected for three cables per bundle at 40 ° C ambient temperature with the rated cur-
rent.
• Use cables with a minimum withstand voltage of 600 V for main circuits.
• If cables are bundled in PVC or metal ducts, consider the reduction ratio of the allowable current.
• Use heat-resistant cables under high ambient or panel temperatures where normal vinyl cables will
rapidly deteriorate.
• Do not use cables under continuous regenerative state.
Wire Size and Allowable Current
The following table shows the wire size and allowable current for three cables. Use a cable whose spec-
ifications meet or are less than allowable current in the table.
• 600 V Heat-resistant Vinyl Cables (HIV)
Note: The values in the table are only for reference.
Power Supply Input Terminals (L1, L2), Motor Connection Terminals (U, V, W),
and Regenerative Unit Connection Terminals (+, -)
Note: Connectors are used for all wiring.
