In all configurations, powersupplies are built in and use standard 240/120 VAC for operation. Electronics are fan-cooled to ensurereliable operation.The MID-7654/7652 simplifies your field wiring through separate encoder, limit switch, and motorpower removable screw terminal connector blocks for each axis. The terminal blocks do not require anyspecial wiring tools for installation. The MID-7654/7652 connects to National Instruments motioncontrollers 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 systempower-down operations. The MID-7654/7652 also has a host bus power interlock that activates aninternal driver inhibit signal if the host computer is shut down or if the motion controller interface cableis disconnected. The inhibit input from the back panel connectors also inhibits the servo drives whenactivated.
