NSI-SC-5915

Panther Motion Controller (PMC), 8-Axis

 

DESCRIPTION

The NSI-SC-5915 Panther Motion Controller (PMC) is an 8-axis micro-stepping controller allowing simultaneous control of up to 8 motion stages . In a combination planar / cylindrical / spherical near-field antenna measurement system, the PMC could control X, Y, Z and POL for the XY scanner, and theta, phi and Z motion for the AUT. Below is a block diagram of a typical antenna measurement system, showing how the PMC connects to the other system components. The PMC has two general-purpose digital I/O ports that can provide TTL step and direction commands as well as inputs for axis limit switches. These ports are typically used to control one or two Antenna Range Controllers (ARC), which provide phased motor currents to drive the axis motors.
