smc5-5-n-n cnc controller price

The motion controller uses high performance 32 bit CPU and high performance FPGA, equipped with 7 inch LCD display, memory using external USB with built-in 8GTF card, large storage space, can be connected with the U disk, the working voltage of 12-24 volts ultra wide input, touc.h type keyboard. The system has the characteristics of high reliability, high precision, small noise and easy operation.
The controller can have five-axis, multi micro segment forward control algorithm can realize five-axis linear interpolation and five-axis micro multi segment continuous interpolation, and the line continued carving control, power down storage coordinate function. Support the hand wheel control interface.
Simple and clear parameters are convenient and quick for your operation. The input / output settings are convenient for you to use and extend the peripherals.


1. Parameter Setting: Various control parameters related to processing and operation can be set to achieve the best processing results.
2. Manual Operation: can be achieved manually, jog back to the program zero, back to mechanical zero, cleared coordinate operations etc.
3. Program Management: program can create, delete, modify, read, save, save, automatic processing, continuous, and pause.
4. External IO Input: a variety of external IO input controls can be defined for convenient using .
5. Free Selection of Input Functions: the limited input port can achieve various users’ needs.
6. Hand Wheel: hold an external hand wheel to control input or host panel advanced function key analog hand wheel, hand wheel support speed mode or position mode.

System composition

The numerical control system is mainly composed of the following parts:
1. High performance, high speed 32 bit ARM CPU, high sex function FPGA.
2. Liquid crystal display (resolution: 800 x 480).
3. Input / output (16 way photoelectric isolation 10MA input, 8 way photoelectric isolation drop tank flow 500MA output).

Technical Parameters:

1. Minimum standard data unit 0.001mm.
2. The general accuracy is positive and negative 2PP.
3. Straight line corner accuracy is one quarter of the corner bow height under normal conditions.
(can be defined as any value to meet the demand for high precision)
4. Maximum data size + 99999.999mm.
5. Maximum pulse output frequency 500KHz (all five-axis can be 500KHZ at the same time).
6. Control axis: 5-axis (X, Y, Z, A, B).
7. Number of linkage-axis: 5-axis linkage and 5-axis multi-line segment forward-looking interpolation control.
8. Hand wheel control speed mode or position mode intelligent cutting deceleration point.
9. The intelligent software is limited to predict the deceleration point ahead of time, the reverse will be automatically lifted and the control is more humanized.
10. Support U disk, built-in memory, which can expand the high storage capacity of 32G
