Every phase winding is monitored so that also uneven currents – and therefore the
associated different thermal loads of the individual phase windings – are detected. For the
following motion and/or operating states, the individual phase windings have different
thermal loads, while the motor simultaneously outputs a torque:
● At standstill (holding)
● When rotating very slowly
● Oscillation through a very small angle
Note
Shutdown time
If Temp
-
S responds, and its response threshold is not undershot again in the meantime, then
the drive system must shut down (de
-energize) the motor within 2 seconds. This prevents
the motor windings from becoming inadmissibly hot.
