Function description

※ Pulse output:
Mode of pulse output: Four pulse outputs, pulse/direction, pulse/pulse, maximum output frequency: 4MHz, uses advanced technology to ensure the error of pulse output frequency is still within 0.1% even it is in high level.
※ Coder input:
Maximum input frequency: 4MHz

Phase difference pulse input or up/down pulse input of 4 axes A/B phase

Pulse frequency multiplication: 4×, 2×, 1×

Noise removing of integration filter
※  Digital switch input:
32-channel optical coupling isolation input, every axis contains two positive and negative limit signals

Input voltage: 5-24V

Isolation voltage 2500VDC
※ Digital switch output:
32-channel open-collector output

NPN open-collector, 5-24VDC, maximum current: 100mA
※ Control mode:
Offer many kinds of control modes such as external signal driving, position lock, automatically back to home, synchronized control ,stepping interpolation, quantitative motion, continuous motion, back-to-home motion, multi-axis interpolation, arc interpolation ,continuous interpolation and emergency stop, etc.
※ External signal driving can be constant driving ,continuous driving or handwheel driving
※  With position lock, you can lock the pulse value of inside counter(logical counter) or external coder(actual position counter)
※ Automatically back to home can be in various modes. The home signals may be combined freely in certain mode. The modes can also be customized.
※ Synchronized control means that the motion axis acts in preset mode when the state of specified signal changes.

※ Steeping interpolation is to perform interpolation in single step, including command driving and external signal driving.
※ Continuous interpolation:
Input the interpolation data of the next command during the interpolation so as to pre-process to ensure the continuity of pulse output, and thus making the interpolation smooth and successive to effectively improve the process precision.
※ Position management:
The position is managed by two UP/DN counters: one is logical position counter used for managing the output of inner drive pulse, and the other is actual position counter used for receiving the input of outer pulse. It is either A/B phase input signal of coder or grating scale, or input signal of up/down pulse. As actual position counter, its bits can reach 32 and the maximum range is -2,147,483,648~+2,147,483,647. The outer input can also be used as hand wheel input for common counting.
※ Speed control:
  The speed control can be constant linear speed (vector composite speed), constant speed or linear/S-curve acceleration/deceleration. It may perform asymmetric linear acceleration/deceleration, automatic and manual deceleration. In constant driving process, it can prevent triangle wave caused by speed curve.
※ Development libraries and operating system:
 Supports DOS, WINDOWS XP/2000/NT/98/95 and WINCE operating system

 Supports programming by developer such as C/BC++/VC/VB/C++Builder/Delphi/Labview/EVC

 Applications based on DOS and Windows
