February 7, 2012 - Jetter updates JetSym programming tool. Version 4.4 contains a range of innovations that make programming and commissioning even more efficient. The most significant changes relate to the setup and programming of servo drives with Motion API (Application Programming Interface) in JetSym STX. Many new options are available as a result, including the collating of several axes into lists, for example.
Individual axes are called up by means of a pointer. This means programs can be structured in a more compact way, since a routine action, which is common to several programs - such as initialization, for example - only has to be written once. Here, the drive is only addressed using the pointer. In addition to this, it is also possible to use axis addresses in functions or objects. When using Motion API, there is no longer any difference for the programmer about whether the axis is connected to the system bus or to the Ethernet.
Motion Setup has been completely revised and can be used for monitoring individual axes. Special attention has been paid in this regard to operability. Input values outside of the intended value range are depicted in red. When selecting the motor, it will be displayed whether different sets of parameters apply to the selected motor. This takes place dependent on the DC link voltage with which it is operated.
On the motion setup pages, the user is supported by a graphic representation of the travel range and by a simple mini-oscilloscope. An autotext function offers the user a range of predefined commands, in which only the variable names need to be entered. This means typical syntax errors can be avoided as early as during the creation of the program's code. The user can also create his or her own sets of commands. In addition, there is a range of other helpful features.
For example, up to 32 channels can now be displayed in the oscilloscope. Further innovations relate to the program editor, the display of variables in the setup window and library management. The latest version of JetSym can be downloaded from the Jetter homepage. The tool can be used and tested without a license for up to 4 kB of compiled program code.
