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)".
(
·
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.
