Table 5-6: Resolver Feedback Device FT1R1 Feedback Device Wiring:
Thermal Device:
Motor equipped with thermal switch designed to switch at 100°C. Tolomatic
recommends the use of the thermal switch in order to protect the actuator in higher ambient
temperatures.
The encoders have internal temperature switches which will deactivate the IMA-S actuator, if thermal
switch is utilized by servo drive.
WARNING!
Encoder temp is not a way to monitor motor temperature.
Performance is based on actuator performance.
WARNING!
In some cases, improper current limits set in the drive, along with
incorrect wiring of the feedback cable can lead to damage of the motor.
5 .3 .3 Thermal Sensor Specifications
Most of the motor windings have an integral normally closed thermal switch. The switch opens at a
temperature of 100°C (212° F), which is the windings maximum operating temperature. The FT1H1
option will include a PT1000 thermistor for measuring the temperature. The thermal switch/ sensor
is meant to protect the windings, the actuators continuous operating region must still be obeyed.
Cycles that cause the windings temperature to approach 100°C (212° F) will reduce the expected
life of the actuator.
