The above mentioned data were calculated for electronics under the following conditions:
SNA: Non-mobile operation
Tu: 40°C - Mean component of ambient temperature
Zf: Continuous operation for 8760 h per year
Programmable Parameters
Resolution per 1° The resolution parameter per 1° is used to program the desired
number of steps per 1°. The values 1, 10 and 100 can be
programmed. Default setting: 100.
Preset Value The Preset value is the desired position value, which should be
reached at a certain physical position of the axis. The position
value is set to the desired process value by the preset parameter.
Moving Avarage-Filter This filter can be used to adjust the bandwidth of measuring
values to minimize the influence of vibration. Factory Setting:
Moving average filter activated for 20 subsequent readouts.
Digital Recursive Filter This filter can be used for weighting the last measured value with
the last previous value. This is useful to suppress sudden peaks in
the angle measurement.
Transmission rate Adjustable: 125 kBaud, 250 kBaud, or 500 kBaud
Factory Setting: 125 KBaud
Address (MAC-ID) Factory setting: Node ID = 63, Adjustable from 0 to 63
Programmable DeviceNet Transmission Modes
Polled Mode Through an I/O-request telegram the connected host calls for the
current process value. The inclinometer reads the current
inclination value, calculates the eventually set-parameters and
sends back the obtained process value.
Cyclic Mode The inclinometer transmits cyclically - without being called by the
host - the current process value. The cycle time can be
programmed in milliseconds for values between 1 ms and 65536
ms.
Change-of-State Mode The inclinometer answers with current process value in case a
change of inclination is detected.
