A graph illustrates the real power (P) over time (t) for status monitoring in a machine tool for milling. It shows a "Switch-on delay", "Delay time", "Motor startup", "Tool positioning", "Milling process", and "Drive shutdown". The graph depicts "Excess performance due to possible broken tool", "Increased performance / Tool wear", "Performance threshold / Broken tool", and "Signaling threshold / Tool wear". The performance level is shown to fluctuate during the milling process, with a baseline "Performance when idling".
Status Monitoring: Air Bubbles in Motor-Operated Pumps
A graph illustrates the real power (P) over time (t) for status monitoring of air bubbles in motor-operated pumps. It shows a "Switch-on delay" and "Delay time".

Status Monitoring: Dry Run in Motor-Operated Pumps
A graph illustrates the real power (P) over time (t) for status monitoring of dry run in motor-operated pumps. It shows a "Switch-on delay" and "Delay time". The graph depicts "Continuous dry running with forced shutdown" and "Performance". It includes a "Lower performance threshold".
Block Diagram
A block diagram shows the internal structure of the EMM 3- 24DC/500AC-16-IFS. It includes inputs for power supply (Us), digital inputs (IN1-IN4), and thermistor inputs (Th1, Th2). The processing unit consists of a "Logic μP" with "IFS-Port" and "Reset" functions. Digital outputs (O1-O4) are provided, along with status indicators (DAT, ERR, L, R). The diagram also shows connections for the motor (P) and the T-BUS for communication.
