2.4 Cable Specifications and Peripheral Devices
Ratings and specifications for peripheral devices, as well as cable specifications for digital
torque amplifiers are summarized in the tables below.
■ Cable Specifications
Notes: 1. Wire sizes were selected for three cables per bundle at 40°C ambient temperature with the rated current.
2. Use cables with a minimum withstand voltage of 600V 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 cable under high ambient or panel temperatures where normal vinyl cable will rapidly
deteriorate.

Wiring Precautions
• Do not bundle or run power and signal lines together in the same duct.
Keep power and signal lines at least 11.81” (30cm) apart.
• Use twisted pair or shielded multi-core twisted pair wires for signal and
encoder (PG) feedback lines.
• The maximum lengths for signal lines are as follows:
• Maximum of 9.84ft (300cm) for reference input lines.
• Maximum of 65.6ft (20m) for PG feedback lines.
• Use a cable with 164 ft (50m) specifications for distances over 65.6ft (20m).
