3.4.2.7 Diagnosis codes
You can use the following diagnosis codes to observe the events on the bus:
• C0359 bus status
• C0360 telegram counter
• C0361 bus load
C0359 bus status
This code shows the present operating state of the bus system.
Value of C0359 Operating state Description
0 Operational The bus system is fully functional
1 Pre-Operational Only parameters (codes) can be transmitted through the bus system. Data exchange between drive con-
trollers is not possible. To change to the Operational state, a special signal must be put out on the bus.
The following actions effect a change of state from Pre-Operational to Operational.
• A drive is defined a the master with C0352. On power-on, after the Boot-Up time C0356/1 that has
been set, an automatic change of state is made for the entire drive group.
• Wiht C0358 Reset-Node (
^
3-22, CAN_ResetNode )
• With the binary input signal Reset-Node, that can be appropriately set
• A Node-Reset through a connected higher-level control system
2 War n i ng Faulty telegrams have arrived. The drive controller is only passively involved, no further data are sent
from the drive controller. The cause may be:
• A missing bus termination
• Insufficent screening
• Potential differences in the grounding of the control electronics
• An excessive bus load
• Drive controller is not connected to the bus
3 Bus Off The frequency of faulty telegrams has caused the drive controller to decouple itself from the bus. It can
be reconnected by:
• ATRIP-reset
• ANode-reset(
^
3-22, CAN_ResetNode )
• A fresh power-on
C0360 telegram counter
All the telegrams for all function blocks and all parameter channels arecounted here, which are valid
for the crivecontroller. Thecounters havea capacity of 16 bits. If a counter exceeds the value 65535,
the count begins again at 0.
The following messages are counted:
C0360/x Meaning
C0360/1 All transmitted telegrams
C0360/2 All received telegrams
C0360/3 Transmitted telegrams fromCAN1_OUT
C0360/4 Transmitted telegrams fromCAN2_OUT
C0360/5 Transmitted telegrams fromCAN3_OUT
C0360/6 Transmitted telegrams from parameter channel 1
C0360/7 Transmitted telegrams from parameter channel 2
C0360/8 Received telegrams from CAN1_IN
C0360/9 Received telegrams from CAN2_IN
C0360/10 Received telegrams from CAN3_IN
C0360/11 Received telegrams from parameter channel 1
C0360/12 Received telegrams from parameter channel 2
