TheMID-7654/7652 simplifies your field wiring through separate encoder,
limitswitch, and motor power removable screw terminal connector blocks
foreach axis. The terminal blocks do not require any special wiring tools
for installation. The MID-7654/7652 connects to National Instruments
motion controllers via a 68-pin, high-density interconnect cable.
TheMID-7654/765 2 has four levelsof amplifier inhibit/disable protectio n
for motion system shut down. The front panel contains both enable and
powerswitches for direct motor in hibiting and system power-down
operations. The MID-7654/7652 also has a host bus powerinterlo ck that
activatesan internal driver inhibit signal if the host computer is shut down
orif the motion controller interface cable is disconnected. The inhibit input
from the back panel connectors also inhibits the servo driveswhen
activated.
Youcan use the MID-7654/7652 enclosure as a benchtop unit, panel
