NB!
Check that the chosen supply voltage follows the specification of the used thermistor element.
Summary
With the Torque limit feature the motor is protected for being overloaded independent of the speed. With the Electronic Thermal Overload the motor is protected
for being over heated and there is no need for any further motor protection. That means when the motor is heated up the Electronic Thermal Overload timer
controls for how long time the motor can be running at the high temperature before it is stopped in order to prevent over heating. If the motor is overloaded
without reaching the temperature where the Electronic Thermal Overload shuts of the motor, the torque limit is protecting the motor and application for being
overloaded.
NB!
Electronic Thermal Overload is activated in par. F-10
Electronic Overload
