WinPC-NC Economy Parameter settings
The spindle speed is generated from WinPC-NC Economy on the
data byte (pin 2-9) of the second LPT port.
Clocking pulse length
Signal-
timing
Controlling stepper motor drives is usually executed by brief
clocking impulses. The pulse duration is susceptible by this
parameter and they are always generated for at least 10µsec.
These impulses may be to short to be recognized by the electronics
when using specific input filters or opto-couplers. Therefore you
have the possibility to prolong this time by parameter. However, it
has to be considered that longer pulse duration may affect calculation
performance and therefore should be avoided.
i
If you really have to set the clocking pulse duration, please select
the smallest possible value in order to guarantee a steady and
constant run of your axes.
Using the SMC version and SMC stepper motor cards the clock pulse
duration is without any impact.
