Introduction
Your MID-7654 or 7652 servo power motor drive is a complete power
amplifier and system interface for use with four or two axes of
simultaneous servo motion control, respectively. The MID-7654/7652
is ideal for industrialand laboratory applications and has everything you
need to connect motors, encoders, limit switches, I/O, and other motion
hardwareto N ational Instruments motion controllers.
The MID-7654/7652 can drivea broad range of servo motors with its
pulse-width modulation (PWM)amplifiers with user-specified peak and
continuousoutput current settings. In all configurations, power supplies are
builtin and use standard 240/120 VAC for operation. Electronics are
fan-cooledto ensu re reliable operation.
