9.2 Typical handling cycle

The following vacuum parameters can be remotely configured using LEMCOM Manager or the
LEMCOM Web Server:
- L1 threshold / h1 hysteresis
Define the vacuum threshold that triggers the "object gripped" signal.
o
o
Master LEMCOM periodically collects gripping status of every module it controls and produces a gripping
status message on the EtherNet/IP™ field bus.
o
Vacuum level value can also be added to the message sent on the bus.
- L2 threshold / h2 hysteresis
o
Define the vacuum threshold that turns OFF internal vacuum command for air saving purpose.
o
Only used if ASC is enabled
- Air Saving Control - ASC (ON/OFF)
o
Enable/disable the regulation system
- DIAG/ECO - DIAG/E (ON/OFF)
o
Enable/disable the system that prevents vacuum valve to turn ON and OFF frequently due to rough or
porous product.
o
Diag Eco can be enabled only if ASC is ON.
o
Diag Eco ON: if regulation system turns ON and OFF the vacuum pilot more than 2 times in a second, it
maintains the vacuum command ON until the end of the cycle to avoid useless wear of the pilot.
- Auto-blow (ON/OFF) + auto-blow duration (millisecond)
o
If turned ON, blow-off is automatically enabled as soon as vacuum command is disabled.
o
The blow-off duration can be set between 1 and 9999 ms.
