2.2.5 CNC Priority
With CNC, the following procedures must be followed. This way the CNC is the master and
the keyboard is the slave, as follows:
•
Parameters managed by CNC: Drive Enable, Reference Enable, Speed References
•
Parameters managed by keyboard (or PC): all dynamic parameters (acceleration, KI, KP,
etc.), Status and Fault.
2.2.5.1 Setting of Analog References
To set the modules to use the analog references from the CNC, it is necessary to enter the
password, to send the AR command to every axis and to save. ST command can be entered
to check if the commands have been accepted.
Note that:
•
AR command can be sent via global address (
∗
).
•
If there are two or more modules, PW (password) and SV (save) commands can be sent to
each module (not only to each axis).
Example of enabling all the analog references for two modules with axes 1,2,3 and 4,5:
FROM KEYBOARD
1 PW91 <CR>
Enter the password for 1st module (primary axis= 1)
PASSWORD ON
The correct answer is displayed
4 PW91 <CR>
Enter the password for 2nd module (primary axis = 4)
PASSWORD ON
The correct answer is displayed
* AR <CR>
Enable analog reference for all axes
1 SV <CR>
Save the configuration for 1st module
4 SV <CR>
Save the configuration for 2nd module
1 ST <CR>
Ask the status for axis 1
A1 ST___ E___ I_0___
Axis 1 status is displayed. Check the 0 in the 2nd bit
after I (bit i)
...
Repeat ST command and check other axes
2.2.5.2 Drive Enable with CNC Priority
To give the priority for enabling and disabling the drive from the CNC, it is necessary to pull
out the personality card from the module, install G2 jumper in position 1-2 (closed) and to
pull in the card.
REMARK: if there are more than one module, do not swap the personality cards, this will
swap the module data.
