Subfunction "Motor protection via TH evaluation"

This function is only active with control via RS485. The additional function triggers error 84 "Motor overtemperature".

The error is triggered when all the following conditions are fulfilled:

  • The standard MOVIMOT® motor protection function is deactivated when DIP switch S1/5 is set to "ON".
  • The direction of rotation terminals are wired to 24 V via a TH as shown in the following figure.

For field distributor:

For mounting close to the motor
with P2.A option:

  • The TH tripped due to motor overtemperature. The enable signal for the two direction of rotation terminals is canceled.
  • Line voltage is connected.

INFORMATION

You can deactivate the "motor protection function using TH evaluation" by setting the DIP switch S1/5 to "OFF". In this case, the motor protection in the MOVIMOT® inverter, implemented via a motor model, is in effect.
