2.MICRO STEPPER MOTOR 2L860 |
-.jpg)
The 2L860 is a high performance microstepping driver based on pure-sinusoidal current control technology. Owing to the above technology and the self-adjustment technology (self-adjust current control parameters) according to different motors, the driven motors can run with smaller noise, lower heating, smoother movement and have better performances at higher speed than most of the drivers in the markets. It is suitable for driving 2-phase and 4-phase hybrid stepping motors.
Features:
-
High performance, cost-effective
-
Automatic idle-current reduction
-
Supply voltage up to +80VDC
-
14 selectable resolutions in decimal and binary, up to 51,200 steps/rev
-
Support PUL/DIR modes and CW/CCW modes ,Pulse input frequency up to 300 KHz
-
Pure-sinusoidal current control technology, Output current up to 7.8A
-
Suitable for 2-phase and 4-phase motors
-
Short-voltage, over-voltage, over-current and over temperature protection
|
Applications
Suitable for a wide range of stepping motors, from NEMA size 17 to 43. It can be used in various kinds of machines, such as X-Y tables, labeling machines, laser cutters, engraving machines, pick-place devices, and so on. Particularly adapt to the applications desired with low noise, low heating, high speed and high precision.
