NSC-G Series Motion Controller

Product catalog summary

NSC-G Series Overview
The NSC-G Series motion controllers are equipped with a 32-bit microcomputer and offer advanced features such as PID compensation with velocity and acceleration feedforward, multitasking program memory for running up to eight programs simultaneously, and uncommitted I/O for synchronizing motion with external events. They support various motion modes including point-to-point positioning, position tracking, jogging, linear and circular interpolation, contouring, electronic gearing, and ECAM. The controllers can be configured to operate up to four stepper or servo motors and are programmed using a simple command language. Communication is facilitated through RS-232 and Ethernet ports, with drivers available for multiple operating systems.

Specifications
The system processor is a Motorola 32-bit microcomputer. Communication interfaces include Ethernet 10BASE-T and RS-232 with ASCII and binary modes. Motion modes supported are point-to-point, position tracking, jogging, 2D linear and circular interpolation, helical, and contouring. The program memory can store 1000 lines of 80 characters each, with 510 variables and 8000 array elements across 30 arrays. The PID filter includes velocity and acceleration feedforward. Kinematic ranges include a position range of 32-bit (±2.15 billion counts per move), velocity up to 12 million counts/sec for servo motors, and acceleration up to 67 million counts. Digital I/O includes 4 inputs and 4 TTL outputs, with dedicated encoder inputs per axis. The minimum servo loop update time is 250 µsec for 1-2 axes and 375 µsec for 3-4 axes. Operating temperature ranges from 0°C to 50°C with humidity between 20-95% RH, non-condensing. Stepper motor driver supply voltage is 24 VDC with up to 3 Amps output current and 256 microsteps. Servo amplifier supply voltage is 48 VDC with brush/brushless trans-conductance PWM, 7 Amps continuous, and 10 Amps peak.

Instruction Set
The NSC-G Series supports a comprehensive instruction set for independent motion commands, contour mode, ECAM/gearing, vector/linear interpolation, Ethernet, servo motor, stepper motor, internal sine commutation, I/O, system configuration, math functions, interrogation, programming, error control, and trippoint. Each category includes specific commands for detailed control and configuration of the motion controller.

Dimensions and Pin Assignments
The document provides detailed pin assignments for motor and signal connectors, including DB-9 and HD-15 connectors for both stepper and servo motor versions. It also includes digital I/O and RS-232 pin assignments.

Ordering Information
The part number configuration for ordering includes options for servo or stepper motor versions, encoder inputs, and the number of axes (1-4). An example part number is provided to illustrate the configuration options.
