Thermal Protection

Software provides an algorithm in order to prevent the motor from thermal overheating under the specified conditions like the valid Flash ROM Data.

After power on reset, the software thermal counter starts to count from the initial value. In case of motor running, software increases the thermal counter by using the motor heating characteristic, otherwise the thermal counter decreases by using the motor cooling characteristic.

There exist 2 thermal protection limits. If the software thermal counter is over the first limit, the motor movement stops until the software thermal counter decrease to the release limit temperature value, but still allows the current movement to finish. If the software thermal counter is over the second limit (while motor running), the movement stops at once until the release temperature value is reached (reversing will not be interrupted by software thermal protection).

Voltage supply = 13.5 V

Load = 3 N.m

Temperature = 23°C± 5°C

The motor is able to continue to operate at least "15" cycles without a break under the above conditions and after thermal protection is activated, the motor turns to the operational condition within "35±5" seconds.

Test starts with SW-thermal counter at the initial value.

Cycle: Full closed → 1sec. rest → Full opened → 1sec. rest
