4.3.3 Stepper control outputs - models NXE100-16xxDx
The stepper control outputs are available on connectors X2 and X3, as shown in section 4.1.1.
There are four sets of stepper motor control outputs, operating in the range 60 Hz to 5 MHz. Each
of the step (pulse) and direction signals from the NextMove
e 100 is driven by DS26LS31 line
drivers, providing RS422 differential outputs. It is recommended to use separate shielded cables
for the step outputs. The shield should be connected at one end only.
The
STEPPERDELAY
keyword allows a 0 - 4.25 μ s delay to be introduced between state
changes of the step and direction outputs. The
FREQ
keyword can be used to directly control the
output frequency, between 60 Hz and 5 MHz. Values less than 60 Hz will produce no output - see
the Mint help file.
The DS26LS31 drivers are static sensitive devices. Take appropriate ESD
precautions when handling the NextMove
e 100. When connecting the outputs to
single ended inputs as shown in Figures 17 and 18, do not connect the STEP x - or
DIR x - outputs to ground; leave them unconnected.
