© National Instruments Corporation 3 MID-7654/7652 Servo Power Motor Drive User Guide
The MID-7654/7652 simplifies your field wiring through separate encoder,
limit switch, and motor power removable screw terminal connector blocks
for each 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.
The MID-7654/7652 has four levels of amplifier inhibit/disable protection
for motion system shut down. The front panel contains both enable and
power switches for direct motor inhibiting and system power-down
operations. The MID-7654/7652 also has a host bus power interlock that
activates an internal driver inhibit signal if the host computer is shut down
or if the motion controller interface cable is disconnected. The inhibit input
from the back panel connectors also inhibits the servo drives when
activated.
You can use the MID-7654/7652 enclosure as a benchtop unit, panel
mounted using apanel mount kit, or rack-mounted using a 19-inchstandard
rack kit.
