The Ndrive MPC is an Automation 3200 compatible eight axis, compact drive chassis capable of operating brushless, DC-brush, and stepper motors. Each drive in the MPC is functionally equivalent to Aerotech’s single-axis Ndrive MP. However, the optimized chassis design uses 46% less space for an equivalent number of axes.
Each drive can be configured with quadrature encoder or analog sin/cos feedback with up to 4096X interpolation. An additional four quadrature encoder inputs are available for dual-loop feedback, handwheel input, or tracking an external encoder for camming and material tracking applications.
Dedicated inputs are provided for Hall-effect sensors, CW/CCW end of travel switches, and Home limit switch. The first four axes are also equipped with a solid-state relay for automatic control of a 24 VDC brake.
The MPC includes 32X opto-isolated inputs and outputs (configurable as sinking or sourcing in blocks of eight), 4X 16-bit single-ended analog outputs and 4X 12-bit differential analog inputs.
Position Synchronized Output (PSO)
The first four drives in the MPC include a differential Position Synchronized Output for precise triggering of external devices based on the feedback position of the axis. The PSO output can also be used as a square-wave function generator with programmable frequency and duty cycle.
Each drive has a separate DC bus input allowing for multiple operating voltages within the MPC. Min/max input voltage range is 10 to 80 VDC. An optional external pre-wired DC power supply is available. Output current per axis is 10 A peak and 5 A continuous. A separate 24-80 VDC input is required to generate low-level control voltages.
