The Siemens 6SE7031-5EF60-Z frequency converter is a power electronics component for feeding three-phase drives in the output range from 37 kW to 400 kW. The Siemens 6SE7031-5EF60-Z can be operated from a three-phase system with a frequency of 50/60 Hz and a voltage in the range of the values entered on the rating plate (380...480 /500...600 / 660...690 V). The three-phase current from the system is rectified, smoothed and fed onto the capacitor DC link. The inverter enables a variable output frequency between 0 Hz and a maximum of 600 Hz to be generated from the DC current with the pulse width modulation method (PWM). The internal DC 24 Vvoltage is supplied through an integral power supply unit. The Siemens 6SE7031-5EF60-Z is controlled by the internal closed-loop electronics, the functions are provided by the unit software. Operator control is via the PMU operator control panel, the user-friendly OP1S operator control panel, the terminal strip or via the serial interfaces of the bus system. For this purpose, the Siemens 6SE7031-5EF60-Z is provided with a number of interfaces and six slots for the use of optional boards. Pulse encoders and analog tachometers can be used as encoders on the motor.
