Safety Notes
In this manual, we will describe important cautionary items which should always be
observed regarding usage, inspection upon receipt of product, mounting, wiring,
operation, and maintenance/inspection.
■ Inspection Upon Receipt of Product
■ Mounting
■ Wiring
• Use the servomotors and amplifiers in the designated combinations. (See “3.5
Combinations” on page 39.)
Failure to do so may result in fire or unit failure.
• Never use this product in an area where water may splash, in a corrosive or flammable
atmosphere, or next to flammable items.
Doing so may result in electric shock or fire.
• Be sure to connect the ground terminal of the digital torque amplifier to a grounding
electrode (100Ω or less).
Failure to do so may result in electric shock or fire.
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 type UL20276-SB for distances over 65.6ft (20m).
