EMM W 3/5-500 Electronic Motor Management Data Sheet 01/2005 Features EMM provides all the advantages of modern active power monitoring. The active-power input of a drive system or another 3-phase load is calculated every 6.6 ms from three currents, voltages, and the phase angle. Currents greater than 5 A are led to the module via transformers. The load is switched by a separate switching element. In this way, the EMM reliably protects connected loads – regardless of their current consumption – against overload and underload and provides continuous status monitoring. Switching thresholds, signaling thresholds, and four configurable confirmation outputs provide motor and system protection. All relevant values can be viewed via the integrated display of the configuration software or a fieldbus interface: – Apparent power, active power, and reactive power – Currents and voltages – Phase angle – Operating cycle counter and elapsed-hour meter – Power meter The integrated memory can be used to record complete curves, which can be used, for example, in the system documentation. Actuators and variable-speed drives, pumps, etc. are connected using the right rotation, left rotation, reverse, and limit switch modes (with integrated restart inhibit) and at the same time are monitored and protected against dirt or wear.
