Introducing the National Instruments MID-7654 Servo Motor Drive, a sophisticated 4-axis motor drive optimized for use with NI-7350 and NI-7340 motion controllers. The MID-7654, identified by part numbers 778005-01 and 778005-05, serves as a fully integrated solution tailored for demanding industrial applications. It employs high-efficiency PWM amplifiers, configured as torque blocks, providing reliable performance in various motion control tasks. The MID-7654 facilitates direct connections for encoders, I/O, motors, and limit switches to the NI motion controllers, ensuring streamlined integration.

Safety features are paramount in the MID-7654, which includes support for critical shutdown signals such as overload and overtemperature alerts. Additionally, a power interlock mechanism initiates a global shutdown if the host computer fails. The front panel is user-friendly, featuring status LEDs, DIP switch banks, an AC power switch, and an enable switch that promptly inhibits the servo amplifiers when deactivated. The drive is configured with default continuous current limits set to 5 A and peak current limits of 10 A, adjustable via DIP switches for each axis as needed.

The rear panel is equipped with a variety of connectors, including those for the motion controller, trigger inputs, analog I/O, AC power, step/direction inputs, and breakpoints, along with dedicated connectors for each axis's encoders, limits, and motors. The MID-7654 is designed to operate within a temperature range of 32 to 122 °F, with a power supply input voltage of 90–132 VAC or 198–264 VAC, and carries a warranty of 2 to 3 years.
