7 Operational behaviour if the bus connection fails
he operational behaviour if the bus connection fails due to bus OFF,
uardin
or
heartbeat error can be parameterised. The required behaviour is set with the
parameter
CAN Error Behaviour 388.
Operation mode Function
0 -No reaction Operating point is maintained
1 -Error Switch-off and display of the error report
2 -
Switch-off Status change - "Switched on" to "Operation released",
Drive mechanism is stopped with stopping behaviour
3 -
Quick stop Status change - "Switched on" to "Operation released",
Drive mechanism is stopped with emergency stop ramp
Attention!
The parameter settings
CAN Error Behaviour 388 = "2 – Switch-off"
and "3 – Quick stop" are only relevant if the further paramete
Local/Remote 412 = "1 - Control via state machine" has been set as a
supplement.
The error and warning behaviour of the frequency inverter can be parameterised in
various ways. If a failure of the bus system occurs in the setting
CAN Erro
Behaviour 388 = "1 – Error", the frequency inverter reports one of the following
errors:
Communication error
Code Meaning
21 Bus OFF
22 Guarding failure
23 Error state
F20
nn Heartbeat failure – nn = node address of the failed subscriber
