Page 7: Introduction
The typical applications areas include injection molding machines, robots, presses, machine tools and similar. The assembly must only be used for the above-mentioned applications and only in connection with recommended or approved third-party equipment. Project engineering manual V1.08 © KEBA 2010... -

Page 9: Safety Notes
It is absolutely essential to observe the safety instructions in the system manual. ● The module is defined as "open type equipment" (UL508) or as "offenes Betriebsmittel" (EN 61131-2) and must therefore be installed in a control cabinet. Project engineering manual V1.08 © KEBA 2010... - Page 10 Improper use of the assembly or the control system leads to irreparable dam- age! ● Turn off the power supply before inserting or removing the module. Other- wise, the module can be destroyed or undefined signal states can lead to damage of the control system. Project engineering manual V1.08 © KEBA 2010...

The simulation mode can be selected through the configuration. The applica- tion has to provide the actual values, which are then read out via the standard interface. This way application tests can be conducted without the incremental encoder being connected. Project engineering manual V1.08 © KEBA 2010... -
Page 25: Operating Behavior
If the maximum input frequency is exceeded, or if the edges of the incremental encoders are too close to one another (e.g. if there is no 90° phase difference between the tracks), this will be identified as error and signaled as such. Project engineering manual V1.08 © KEBA 2010... -
