Control 8SMC4-USB via Ethernet New!

Close relation between Standa’s customers influenced Standa to modify its 8SMC1. Tens of thousands of 8SMC1 stepper motor controllers take part in the market. With respect to the users, Standa has developed the new controller – 8SMC4 with a modern design and increased functionalities for photonics and industrial applications. Whats the difference? Look here!

Brief description

An overview of today’s approaches for flexible motion control in lab experiments is given. With modern controller design even simple and inexpensive positioners can be utilized to achieve high speed and precision. It doesn’t matter which motor technology you prefer: stepper or DC because one controller can drive them all. Multi-axis control, developing custom motion control software for any OS, automatic positioners recognition and using various peripherals are all easy now.

Supported types of motors

One controller, one interface for any type of motor!
•   Bipolar Stepper (rotational/linear)
•   DC
•   BLDC (rotational/linear)

The controller is great at driving bipolar stepper motors with a rated winding current of up to 3 A (by request up to 6 A, 48 V) and DC motors with rated current up to 6 A. All you need to do is plug it in, no assembly required.

Multiple controllers can be connected to one computer either via USB ports or through a special hub that provide axis synchronization.

The controller’s software is fully compatible with almost all operating systems, e.g., Windows, Mac OS X, Linux, etc. You can test the software with virtual controllers simulated by the software. The software provides javascript like scripting language to quickly automate your task or you can use a cross platform library with code examples on C, Visual Basic, Matlab, Labview, C# to build your own software.

Optionally the controller can be managed with the same instructions set, as from USB interface, by using many of popular serial interfaces like Bluetooth, Ethernet, RS422 or RS232 – requires converters from TTL logic signals RX and TX. These signals are located on the backplane connector of the controller circuit board. Communication speed, parity and stop bits are wide configurable. Default interface is USB, but on request Standa can produce controllers with required interface. Test the controller 8SMC4 instantly as it comes with the manual control buttons, they could be used for ease testing of your equipment or controller itself even without a PC.

For faster starting your task Standa continuously develop new configuration files for motorized stages.

Software

XILab features two user-friendly graphical interfaces, which are designed for positioners control, diagnostic and fine tuning of the motors driven by the controllers.
The control process can be automated with the scripting option that can be used either directly or to speed up the process of customized control program development. XiLab supports multiaxial mode and multidimensional control scripts. It is possible to output motor and controller status in form of charts and save them to a file. XILab software has two types of interfaces: Single-axis control and Multi-axis control.

Single-axis and Multi-axis control interfaces contain motor and controller parameters: position, speed, voltage, current and temperature. Advanced joystick and units conversion block are only available in Multi-axis interface. You can choose any of these interfaces that fits your application the best.
