Specific Features of Double-Axis Devices (Firmware
MPD)
Basically, the existing inputs and outputs can be freely assigned to all
axes. To do this the parameters P-0-0300, P-0-0301, P-0-0302 are
available for both axes.
There are the following restrictions:
•
A digital output can only be used by one axis. All other axes have to
deactivate this output by the entry "S-0-0000" in parameter P-0-0300.
•
The output contact of the relay "Rel1" is an exception. It can be used
by both axes. The default assignment is the "ready for operation"
message (see Parameter Description P-0-0300). For controlling the
relay the information of both axes is ANDed.
•
An input can only be used simultaneously by both axes, if it is used by
both axes with the same IDN, bit number and directional assignment
(for inputs/outputs).
•
A digital input
cannot
be used simultaneously by both axes, if the
assignment parameters of both axes differ in the respective line with
regard to the IDN (P-0-0300), bit number (P-0-0301) or directional
assignment (P-0-0302). The respective line of P-0-0300 of one of the
two axes has to contain "S-0-0000" (
→
no assignment)!
Note:
The above-mentioned restrictions are checked in the transition
command from phase 3 to phase 4 (cf. C2000). In the case of
conflict, the corresponding diagnostic message is generated.
Special Cases and Exceptions
In some special cases there is no direct bit transfer, because the function
assigned to the input/output is more complex. An example is the probe
function. In this case, the entry in P-0-0301 is irrelevant, it is only a valid
value that has to be contained (e.g. "0").
All special functions are listed in the following table:

As a matter of principle, the inputs/outputs can be freely configured. Only
for special functions has a fixed assignment of the inputs/outputs to
corresponding parameters been defined. With the default configuration
(= condition as supplied or status after "basic parameter load"), the
following inputs/outputs are already predefined:
•
probe inputs (MT1, MT2)
•
travel range limit switches (Limit+, Limit-)
•
reference switch cams (NS)
•
E-Stop input (E-Stop)
•
"ready for operation" output ("bb" contact)
