 Setting possible

This monitoring function is designed as an early warning stage before final disconnection of the drive

controller by means of TRIP (OH3) via the monitoring function "motor temperature (fixed)".

(^ 2−85)

 With this function the process can be influenced to avoid a switch−off of the motor at an

unfavourable moment.

 Furthermore, for instance, additional fans, which would cause an unacceptable noise in

continuous operation, can be switched on and off.

MCTRL_bMotorTempGreaterC0121_bis derived from a comparator with hysteresis.

 The operating threshold is set under C0121.

 Hysteresis is 15 K (fixed), i. e. monitoring is reset at 15 K below the operation threshold that

has been set.

 The response is set under C0584.
