• Power on – Inclinometer doesn’t respond
Problem:
If the bus is active, then, 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 value
occasional malfunctions occur. The CAN bus
can be temporabily in the bus off state also
Possible solution:
Please check if the last bus nodes have the
terminal resistor. If the last bus node is an
inclinometer the terminal resistor is to be
added.
• 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
baudrate. Even if one node has a different
baudrate, error frames
are
produced
automatically.
• Unexpected module / Module missing /
Wrong Module
Problem:
Improper definition of node address or
improper loading of EDS file.
Solution:
Reinitialize the CAN bus or re-install the EDS
file.
• Node state stopped upon loading and
initialization
Problem:
Mostly because the bus transmission timeout
is defined lesser than the ACS transmission
time.
Solution:
Increase
the
bus
timeout
period
(
Approximately 2-3 seconds).
• Unable to change to another node number.
If all nodes are found to be in operational
mode, then follow the next few steps to set
the required node number to a selected
device.
1. Calculate the required node number in
hexadecimal.
(
ACS
is
internally
programmed to add 1 to any node number
change fed to it, in order to avoid the node
number 0)
