Handling faults in the master and slave drives

Overview If a coupling is active, the master drive must be able to respond to
slave drive faults.
It must also be guaranteed that the slave drive is reliably stopped, if the
master drive develops a fault.
Faults in the slave Dependent on the stop responses, the following should be observed for
drive faults and warnings in the slave drive:

Note:
The required stop response can be initiated for a group of axes by appropri-
ately externally evaluating the output signals of the slave drive.

tions
S
The coupling is disconnected (switched–out)
S
The slave drive is appropriately braked
S
Output signals
– Status, controller enable = 0
– Fault present
– Warning present
S
Block processing is interrupted
S
The slave drive remains closed–loop controlled and
coupled
S
Output signals
– Status, controller enable = 1
– Fault present
– Warning present
S
No response for the slave drive
S
Output signals
– Status, controller enable = 1
– Fault present
– Warning present
S
When the controller enable is withdrawn, this does not
have to result in faults being output
S
Output signals
– Status, controller enable = 0
– Fault present
– Warning present
