Digitizing With a Host
The VXM stores its absolute position (relative to when registers were zeroed) in memory. The
absolute registers reflect the accumulated distance from operating the motors in the Jog
mode and/or under program control. These registers can hold from -8,388,608 to +8,388,607
steps.
With a host terminal or computer connected via the RS-232 interface, the VXM can be used
as a digitizer. In the Jog mode the VXM will send motor position when it receives a "D" from the
host.
Here is an example of what the host would receive when Motor 1 is at absolute 201, Motor 2 is
at absolute -1294010, Motor 3 is at absolute 0, and Motor 4 is at 80000:
X+0000201<cr>
Y-1294010<cr>
Z+0000000<cr>
T+0080000<cr>
X+0000201<cr>
Y-1294010<cr>
Z+0000000<cr>
T+0080000<cr>
NOTE: VXM will only send the X and Y motor positions in a single VXM system. The
above example is from a Master/Slave VXM system.
Enabling Jog When a Program is Running
U2 Enable Jog while waiting for an input. This command will allow motor jogging,
with the jog button/inputs, during the following wait commands:
U0,U1,U30,U31,U50,U51, or U90.
Memory usage = 2 bytes.
U3 Disable Jog while waiting for an input (default setting on power-up.) This
command will disable motor jogging during a wait command.
Memory usage 2 bytes.
