Signal name, description
Activate coupling via I0.x (from SW 3.3)
The coupling, set via P0410 is activated via the fast input I0.x using this input signal.
The activate coupling "input signal" (function number 72) prepares the switching–in process via terminal
I0.x.
The edge of the input signal "activate coupling via I0.x" (function number 73) switches–in the coupling.
The coupling is switched–out via the "activate coupling" input signal (function number 72).
1 signal No significance
1/0 signal This edge switches–in the coupling for a positive traversing direction of the master axis
0/1 signal This edge switches–in the coupling for a negative traversing direction of the master axis
Prerequisites:
Input signal, "activate coupling" (function number 72) = "1"
0 signal No significance
Input signal, "activate coupling"
Input terminal with function number 72 or
control signal PosStw.4
Input signal, "activate coupling via I0.x"
Input terminal I0.x with function number 73
Note:
S
The position when switching–in the coupling is displayed in P0425:0.
S
Function number 73 is only effective when assigned to input terminal I0.x.
S
The "activate coupling via I0.x" signal is recognized, dependent on the direction.
––> refer under the index entry "Input signal, digital – external block change"
S
The "axis coupling" function is described in Chapter 6.3.
Set setpoint, master drive (from SW 4.1)
The absolute position of the master drive is set in the slave drive to the reference point coordinates using
this input signal.
1 signal No significance
0/1 signal The absolute position of the master drive is signaled to the slave drive once
0 signal No significance
Note:
S
The input signal "set setpoint, master drive" is only required for P0891 = 0 or 1. Only after this, may a
coupling be switched–in to the absolute position of the master drive (P0410 = 7 or 8)
––> otherwise, Fault 177 is output.
S
The reference point coordinates of the master drive are signaled to the slave drive using P0400.
S
The "axis coupling" function is described in Chapter 6.3.
