WEG DeviceNet CFW500 - P0703 - Bus off Reset; P0705 - Can Controller Status

P0703 – BUS OFF RESET
Range: 0 = Manual Default: 0
1 = Automatic
Properties: CFG
Access groups via HMI: NET
Description:
It allows programming the inverter behavior when detecting a bus off error at the CAN interface:
Table 4.5: Options for the parameter P0703
Option
Description
0 = Manual Reset
If bus off occurs, the A134/F234 alarm will be indicated on the HMI,
the action programmed in parameter P0313 will be executed and the
communication will be disabled. In order that the inverter
communicates again through the CAN interface, it will be necessary
to cycle the power of the inverter.
1= Automatic Reset
If bus off occurs, the communication will be reinitiated automatically
and the error will be ignored. In this case the alarm will not be
indicated on the HMI and the inverter will not execute the action
programmed in P0313.
P0705 – CAN CONTROLLER STATUS
Range: 0 = Disabled Default: -
1 = Autobaud
2 = CAN Enabled
3 = Warning
4 = Error Passive
5 = Bus Off
6 = No Bus Power
Properties: RO
Access groups via HMI: NET
Description:
It allows identifying if the CAN interface board is properly installed and if the communication presents errors.
Table 4.6: Values for the parameter P0705
Value
Description
0 = Disabled
Inactive CAN interface. It occurs when the equipment does not have the CAN
interface installed.
1 = Autobaud
CAN controller is trying to detect baud rate of the network (only for DeviceNet
communication protocol).
2 = CAN Enabled
CAN interface is active and without errors.
3 = Warning
CAN controller has reached the warning state.
4 = Error Passive
CAN controller has reached the error passive state.
5 = Bus Off
CAN controller has reached the bus off state.
6 = No Bus Power
CAN interface does not have power supply between the pins 1 and 5 of the
connector.
