& velocity must fall within the peak region of the actuator system. Higher peak thrusts are achievable by the
actuator system, so please consult Tolomatic before exceeding catalog ratings. Use the following formulas when
calculating the RMS thrust & velocity. When selecting a servo motor actuator system, it is recommended to add a
margin of safety of 15% to the thrust and velocity required to move the load.

A.8 Standard thermal switch specifications
The motor windings have an integral normally closed thermal switch or resistance based temperature
measurement device. These devices must be integrated with the robot controller. The switch opens at a
temperature of 212° F (100°C), which is the windings maximum operating temperature. The thermal switch is
meant to protect the windings, the actuators continuous operating region must still be obeyed. Operation that
causes the windings temperature to approach 212° F (100°C) will reduce the expected life of the actuator.
