CAHB-20 series
Adjustable end stop (S design only)
The smart CAHB-xS are delivered with the end stop accord-
ing to the retracted length and the stroke length of the actu-
ator (see the ordering key). If the application on the equip-
ment or the vehicle request an adjustment of the retracted
andextendedlength,asimpleandsafelearningprocedure
by the 2 motion inputs or by CAN bus will memorized the re-
quested lengths.
Monitoring and Diagnostic
(S design only)
Thekeyparameteroftheactuatorlikecurrent,voltageand
environmental data like the temperature are tracked and re-
cordedincaseofoverspecication.Thediagnosticisavail-
ablethroughthebuscommunication,soonboardiftheac-
tuatorisconnectedtoanElectronicControleUnit,ECU,by
theCANbusoro-boardiftheCANbusisconnectedonly
during overhaul and maintenance of the equipment or the
vehicle.
Bus communication (S design only)
A bus communcation CAN bus SAE J1939 equipped all
smart CAHB-2xS actuator. It could be used to have ad-
vanced control of the actuator like go to a position or oper-
ate at a lower speed but also to read the monitoring and get
the diagnostic.
Parallel motion option (S design only)
Asetofactuatorcouldbedenedasagroupofactuator
that should work at the same length during the complete
motion until the stop. A command to any actuator of the
groupwillbeenoughifallactuatorswerepredened.Allac-
tuators will monitor their relative position and will decide to
follow the slowest actuator. No downgrade speed perfor-
mance,themovementwillrunatthefastestspeeddepend-
ing the load.
Position, speed and force control.
The CAHB2-xS can receive a command by CAN bus to con-
trolthelengthsetin0.1mm,aspecicspeedsetin%ofthe
maximum speed and maximum force set in N. The move-
ment will be monitored to follow the command including a
soft start and soft stop to perform a smooth movement.
Thermal protection
Thethermalswitchbuilt-inthemotorwillswitchothe
power of the motor in case of over heat of the motor. It will
automatically reset when the temperature decreases.
Overload or more frequent operating the actuator over the
maximumdutycyclesdenedonthedatasheetwouldlead
to motor overheating.
CAUTION
To prevent damage from overheating when the actuator stop with
ahighmotortemperature,donotrestarttheactuatorbutwaituntil
the temperature decreases.
Automotive vent
The vent allows the equalization of the pressure inside the
actuatorwhenitisoperated,thatwillinsureanoptimumus-
age of the sealing system
