    Glossary 3-phase busbar The 3-phase busbar enables several compact starters to be fed using a single infeed terminal. 8US busbar adapter The 8US busbar adapter enables the compact starter to be mechanically fastened and electrically connected to a busbar system. Adapter for screw fastening The adapters for screw fastening enable you to install the compact starter on a level surface.
  • Page 178 Glossary Motor model The electronics calculate the motor temperature continuously in accordance with the operating time and current load and store this information in a thermal motor model. Process image The process image is used for buffering input and output data. When the control system starts cyclic program execution, the signal states of the compact starter are transferred to the process input image of the higher-level control system.
