4.4 Other I/O
4.4.1 Stepper control outputs - models NSB202... / NSB204...
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 0 Hz to
500 kHz. Each of the step (pulse) and direction signals from the NextMove ESB-2 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 μs 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 500 kHz - see the Mint help file.
The DS26LS31 drivers are static sensitive devices. Take appropriate ESD
precautions when handling the NextMove ESB-2. When connecting the outputs
to single ended inputs as shown in Figures 17 and 18, do not connect the
STEPx- or DIRx- outputs to ground; leave them unconnected.
