Inverter temperature warning

15 °C

Defines the temperature difference (in ºC) between the Overtemperature trip threshold and the warning threshold of the inverter. The trip threshold is stored internally by the inverter and cannot be changed by the user.

Delay, fan shutdown

0 s

This defines the delay time in seconds between powering down the frequency inverter and then powering-down the fan. A setting of 0 means that the fan is immediately shut down (powered-down).

6.4.14Motor protection

In addition to the thermal motor protection, the motor temperature is also included in the adaptation of the motor equivalent circuit diagram data. Especially for a high thermal motor load, this adaptation has a significant influence on the degree of stability of the closed-loop vector control. For MM440 the motor temperature can only be measured using a KTY84 sensor. For the parameter setting P0601 = 0,1, the motor temperature is calculated / estimated using the thermal motor model.

If the frequency inverter is permanently supplied with an external 24V voltage, then the motor temperature is also tracked/corrected using the motor temperature time constant – even when the line supply voltage is switched-out.
