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. At the end of the cyclic program, the
process output image is transferred to the compact starter as the signal state.
Terminals for Type E combination controller
The terminals conform to the creepages and clearances stipulated by UL 508 (Type E).
