 Setting possible

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

controller by means of TRIP (OH) via the monitoring function "heatsink temperature (fixed)".

(^ 2−73)

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

unfavourable moment.

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

continuous operation, can also be switched on and off.

MCTRL_bKuehlGreaterC0122_b is derived from a comparator with hysteresis.

 The operating threshold is set under C0122.

 Hysteresis is 5 K (fixed), i. e. monitoring is reset at 5 K below the operation threshold that has

been set.

 The response is set under C0582.
