PMDX is now shipping two new boards in our line of
SmartBOB-USB products for Mach4 users.
The PMDX-410 SmartBOB-USB is a motion control engine
for use with existing breakout boards or with driver
boxes such as the PMDX-340 or the GeckoDrive G540. It
is derived from the PMDX-422 but omits the relay and
the terminal strips for the pins that are part of the
standard parallel port. These signals are served by
the 26 pin ribbon header which is used to connect the
parallel port signals to the mating ribbon header or
DB-25 connector on the companion device.
The extra signals available from a SmartBOB-USB, above
and beyond those in a standard parallel port, are still
made available on a pluggable terminal strip.
The PMDX-410 is priced at $129 each and can be bundled
with the Mach4Hobby software for a $10 discount.
The PMDX-407 is a basic spindle speed control interface
that mounts on top of a PMDX-410 or PMDX-422 and provides
an analog speed control voltage for VFDs or other spindle
drives. There is also a set of RUN contacts to turn the
spindle on and off. Optical isolation is provided between
both output circuits and the control circuits that come
from the SmartBOB.
The RUN contacts can directly switch 120 VAC to control
small contactors such as the PMDX-ContactorMD20-120. Using
a contactor to control the AC mains input to a DC spindle
driver provides failsafe operation of those DC spindle drives
that do not have an electronic input for real on/off control.
This includes the KBIC motor controller from Penta used on
the Sherline machines and also those found on most imported
mills and lathes with DC spindle motors.
Direction control of VFDs is optionally available by using
the relay on the PMDX-422.
The PMDX-407 is priced at $38 each.
