Cable lengths
The cable length is restricted by the Ethernet specifications, cables must not exceed a
length of 100 m.
9
Setting the node address
Adjustment of the node address is not required. The EtherCAT
®
master will set an
unambiguous, singular 16-bit address for each device upon startup.

Operational behaviour on bus failure
The operational behaviour if the EtherCAT
®
system fails can be parameterized. The
required behaviour is set with parameter
Bus Error Behaviour
388.
CAN Error Behaviour
388
Function
0 - No Reaction
Operating point is maintained
1 - Error
Device state machine changes immediately to state
“fault” (factory setting)
2 - Switch-off
Device state machine processes command ‘
disable
voltage’ and changes to state “switch on disabled”
3 - Quick-Stop
Device state machine processes command ‘
quick stop’
and changes to state “switch on disabled”
4 - Ramp-Stop + Error
Device state machine processes command ‘
disable op-
eration’ and changes to state “fault” after the drive is
stopped
5 - Quick-Stop + Error
Device state machine processes command ‘
quick stop’
and changes to state “fault” after the drive is stopped
NOTE
The parameter settings
Bus Error Behaviour
388 = 2 … 5 are evaluated depending
of parameter
Local/Remote
412.
The error and warning behaviour of the frequency inverter can be parameterized in
various ways. Occurring errors are described in detail in chapter 16.4 “Fault messag-
es”.
