At approximately 270°:
IK360 position value = 27256 * 0.01 =272.56°
All the above position values where obtained by programming the position value output
explicitly. The other method is very simple and direct.
Just run the controller and same position values are obtained. The position is mapped with the
memory location %IWC1.0.0 or %IWC1.1.0 through PDO mapping done in the earlier steps.
The steps for the mapping have been illustrated in above parts so that, in real time application,
end users can directly follow the above steps to read out the position values from the mapped
memory locations.

Troubleshooting
Power on
– Inclinometer doesn’t respond
Problem:
If the bus is active, than the installed inclinometer is transmitting a false node number. If the bus
is inactive, then it was connected with an incorrect baud rate.
Possible solution:
-
Modus pre-operational
-
Adressing the inclinometer via SDO
-
Reset or power off
-
Reprogram the baud rate
Malfunction of the position value during transmission
Problem:
During the transmission of the position valueoccasional malfunctions occur. The CAN bus also
can be temporabily in the bus off state.
Possible solution:
Please check, if the last bus nodes have the terminal resistor. If the last bus node is an
inclinometer, add a terminal resistor.
Too many ERROR-Frames
Problem:
The bus load is too high in case of too many error frames.
Possible solution:
Check, if all bus nodes have the same baud rate. Even if one node has a different baud rate,
error frames are produced automatically.
