Condition Monitoring (CM) [0x0092]
Monitoring valve switching frequency for grippers FXP-i
When the air saving function is activated and there is a high leakage level in the gripping system, the area gripper FXP-
i switches between the suction and suction-off states very frequently. The number of valve switching procedures thus
increases rapidly within a short time.
To protect the area gripper and increase its service life, the area gripper automatically deactivates the air saving
function and switches to continuous suction if the switching frequency > 6/3 s (more than 6 switching operations
within 3 seconds). The area gripper then remains in suction mode.
It also issues a warning and sets the corresponding condition monitoring bit.
This function is deactivated for grippers of type FMP-i.
Monitoring evacuation time
Measuring the evacuation time t1:
The interval between reaching the switching points SP2 and SP1 is measured (in ms).
If the measured evacuation time t1 (from SP2 to SP1) exceeds the specified value, the “Evacuation time longer than t-
1” condition monitoring warning is triggered and the system status light switches to yellow.
