 Setting possible

MCTRL_bMotorTempGreaterSetValue_b is derived from a comparator with hysteresis. The

switch−off threshold and the hysteresis are fixed:

 The switch−off threshold is 150 °C

 The hysteresis is 15 K, i.e. the value for switching on again is 135 ºC.

This monitoring only applies to the temperature sensor specified by Lenze as it is, for instance,

included in the Lenze standard servo motor.

 The Sub−D connectors X7 or X8 are available as inputs.

Stop!

The temperature sensor may either be connected to X7 or to X8; the respective other input for the

temperature sensor must be free!

This monitoring is active in the Lenze setting and is thus triggered when you use a non−Lenze servo

motor!

 The response is set under C0583:
