MUFACE ® V4
Intelligent Motor User interFACE
and Stepping Motor Controller
1. Introduction of MUFACE
Muface is a stepping motor controller and has two main components: A software and a hardware component. The Muface software runs on a PC and
it is DOS based. (A newer user interface called Javamotion is written in Java and runs on any Windows-based Java virtual machine.) The Muface
software communicates with the Muface hardware component over a serial line (RS232). The user interface is designed to make writing stepping motor programs easy. When you choose "Motor start", the Muface program computes the precise motor sequences and sends them over the serial line to the Muface hardware, which immediately executes the program. The strength of the Muface system is to drive stepping motors with high accuracy. For example, the frequency resolution in burst sequences up to 100kHz is 7 decimal digits. Since Muface programs feature looping constructs, as well as conditional branching constructs (condition on the value of an input), you can also use the Muface system to perform measurement-and-control tasks, with great simplicity.
2. Advantages of Muface
- Ease-of-use. No previous programming experience is necessary, the Muface programming environment is intuitive to use, it only requires minutes to master.
- No special hardware card in the PC necessary.
- After the program is stored on the Muface hardware, the program executes autonomously, without the support of the PC Muface software.
- Highly accurate frequency generation.
- A wide variety of stepping motors can be used with the corresponding drivers.
- Muface supports 3 types of ramps: Linear, exponential, and user-defined ramps. Each ramp is defined through start and end
frequency, as well as the number of steps. Muface automatically computes these ramps and can output a time-frequency table, that you can view in
Excel, for example.
