This monitoring function sends a warning before the controller is switched off because of a TRIP
(OH3) using the function “Motor temperature (fixed)”.
•
Thus, the process can be influenced to avoid a switch-off of the controller at an inconvenient
time.
•
Additionally, fans which would cause an unacceptable noise in continuous operation, can also
be switched on and off.
MCTRL_bMotorTempGreaterC0121_b
is derived from a comparator with hysteresis.
•
The threshold can be set under C0121:
