Travel to fixed endstop and axis coupling
– It is not permissible to activate the ”travel to fixed endstop” func-
tion when in the coupled mode (Fault 173).
– The axis coupling cannot be switched–in during the ”travel to
fixed endstop” function (Fault 173).
If it is predicted that a software limit switch will be passed, for
coupled axes, one of the following faults/warnings will be signaled:
– Fault 132 or 133 after a software limit switch has been passed
(minus or plus)
– Warning 891
(software limit switch PLUS actuated, coupled)
– Warning 892
(software limit switch MINUS actuated, coupled)
For a coupled drive, there is no response to warning 891 or 892.
This can be signaled to the master drive using the output signal
”warning present”; this then allows the master drive to respond.
Only relative position data is permissible for traversing blocks when
in the coupled mode (Fault 165).
During an active coupling, a block change enable
CONTINUE EXTERNAL is only possible with P0110 = 2 (Fault 172).
The position of the master drive, at which the coupling was re-
quested, is in P0425:0.
The following applies for P0410 = 1, 2 or 7:
– It is not possible to program the commands COUPLING_IN
or COUPLING_OUT (Fault 166).
– The coupling can be switched–in/switched–out via input terminal
as follows:
1.)
Assign function 72 to any input terminal
––> Input signal ”activate coupling”
or
2.) (recommendation, as it is a fast input)
Assign function number 73 to input terminal I0.x
––> Assign the input signal ”Activate coupling via I0.x”
and
function number 72 to any other input terminal
––> Input signal ”Activate coupling”
(refer to Chapter 6.4.3 Function numbers 72 and 73)
The following applies for P0410 = 3, 4 or 8:
The coupling cannot be switched–in/switched–out via an input signal.
