Corrective action
The workpiece weighs too much
Use a larger gripping module
The gripper jaws are too long
Place the gripping point further inside
Non-optimal engineering design
Adapt the engineering design – form-fit
gripping
6.7 Module does not achieve the opening and closing times?
Possible cause
Corrective action
Compressed air lines are not installed
optimally.
Check compressed air lines.
Inner diameters of compressed air lines are
of sufficient size in relation to compressed
air consumption.
Keep compressed air lines between the
product and directional control valve as
short as possible.
Flow rate of valve is sufficiently large
relative to the compressed air consumption.
6.8 End position signal not present?
Possible cause
Corrective action
Precisely adjust the sensor for the stop
Readjust the sensor
Proximity switch defective or set incorrect.
Replace sensor
