Over Temperature Protection
UL approved motor over temperature sensing is not provided by
the drive.
The motor contains a UL recognized temperature sensor embedded in
the stator windings which opens when the stator temperature reaches
130⁰C. This sensor is permanently connected to the Tritex drive and will
generate an Actuator Overtemperature fault.
The drive also provides motor over temperature protection by limiting
the continuous current to the motor. The continuous current limits are set
at the factory and cannot be adjusted. These limits are set to keep the
stator below 130⁰C while in a stall condition at 25⁰C Deg ambient.
Additional over temperature protection is provided by a sensor in the
drive electronics which generates a fault when the board reaches 100⁰C.
The factory default setting for action when reaching overtemperature
and continuous overcurrent limits is to immediately disable the drive,
providing drive, motor/actuator or customer tooling protection. The user
may override this protection to allow the actuator to move to a safe
position before disabling or take similar immediate controlled action.
