Introduction
National Instruments’MID-7604/7602 power driveis a complete power
amplifierand system interface for use with f ouro r twoaxes of
simultaneous stepper motion control. Ideally suited to industrial and
laboratory applications, the MID-7604/7602 has everything you need to
connectmotors, encoders, limit sw itches, I/O, and other motion hardware
to National Instruments’motion controllers.
The MID-7604/7602 can drivea broad range of stepper motors with its
rugged microstepping bipolar chopper driver and user-selectable
current-per-phasesettings. In all configurations, power supplies are built-in
anduse standard 230/115 VAC for operation. Electronics are fan-cooled to
assure reliable operation.
TheMID-7604/7602 simplifies field wiring through separate encoder, limit
switch,and motor power removable screw terminal connector blocks for
each axis.T he terminal blocks do not require special wiringtools for
installation. The MID-7604/7602 connects to National Instruments’
motion controllers via a 68-pin, high-density interconnect cable.
TheMID-7604/760 2 has four levelsof amplifier inhibit/disable protectio n
for motion system shutdown. The front panel contains both enable and
powerswitches for direct motor in hibiting and system power-down
operations. The MID-7604/7602 also has a host bus powerinterlo ck that
activatesan internal driver inhibit signal if the host computer is shut down
ort he motion controller interface cable is disconnected. The inhibit input
from the back panel connectors also inhibits the stepper drives when
activated.
The MID-7604/7602 is packaged in a rugged, lightweight enclosure that
canbe used as a benchtop unit, pa nelmo unted using a panel-mount kit, or
rack mounted usinga 19-inch standard rack kit.
