Precautions for Allowable Load and Installation
Rated load, rated moment, and rated torque in the ATC specifications are
dynamic specifications for the unit being mounted on a robot. Ensure that the
maximum load never exceeds these values during normal operations taking
into account the acceleration factor during acceleration/deceleration by the
robot. Fig. 2 shows the meanings of rated load, rated moment and rated
torque.

WARNING
The ATC with the standard signal pin ASSY (20-pin), as an entire contact ASSY,
is capable of carrying up to 13A current. Also, each of the pins is capable of
carrying 3A current. However, when multiple signal pins are to used, do not let
3A current applied to any adjacent pin as it will cause insufficient insulation,
leading to short circuit.
CAUTION
