Function And Features; Operating Principle - IFM Electronic Ecomat 100 Handbuch

Function and features

The 2-axis inclination sensor with CANopen interface enables angle levelling and
position detection of mobile machines. Typical applications are for example the
position detection of access platforms, levelling of mobile cranes and mobile
machines.

Operating principle

Two measuring cells which operate to the conductometric principle evaluate the
change in conductivity of a liquid.
Depending on the sensor inclination the electrodes in the liquid are exposed to
different degrees of wetness. This leads to characteristics comparable to a poten-
tiometer. Arranging the electrodes crosswise results in the signed values for the
two axes.
Features at a glance
• When using the sensor on the CAN bus the resolution parameter can be set
and the 2-axis zero point can be freely selected.
• 1 server SDO and 3 Transmit PDOs conforming to CiA DS 401 are available. The
PDO mapping cannot be changed (static PDO mapping). Default identifiers have
been assigned according to the "predefined connection set".
• The COB IDs of the PDOs as well as the type of transmission (synch/asynch) of
the individual PDOs can be configured.
The type of transmission is stored non volatilely. Changed PDOs (PDO linking)
are stored volatilely.
• The inclination sensor expects a synch object. The CAN identifier of the synch
object can be configured. After a change the ID is automatically stored non
volatilely.
• The inclination sensor supports "node guarding" and "heartbeat".
The "guard time", "life time factor" and "heartbeat time" are configurable
and stored non volatilely.
• The inclination sensor generates an emergency object. The COB ID of the
EMCY object can be configured.
• The inclination sensor stores the last 4 errors occurred. The error code of the
respective emergency object is stored.
• The inclination sensor supports a reset function, i.e. upon request the parame-
ters are assigned to the factory default values*.
• In addition, the inclination sensor has two analogue outputs.
The measured values -45°...+45° are provided as 4...20 mA current values.
