SIMOVERT MASTERDRIVES
The frequency converter is a power electronics component for feeding
highly dynamic three-phase drives in the output range from 2.2 kW to
37 kW.
The unit can be operated from a three-phase system with a voltage
between 380 V and 480 V and a frequency of 50/60 Hz.
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
400 Hz to be generated from the direct current with the pulse width
modulation method (PWM).
The internal DC 24 V voltage is supplied through an integral power
supply unit from the DC link.
The unit is controlled by the internal closed-loop electronics, consisting
of a microprocessor and a digital signal processor (DSP). 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 a bus system. For this purpose, the unit is provided with a
number interfaces and six slots for the use of optional boards.
Resolvers, encoders, pulse encoders and multiturn encoders can be
used as encoders on the motor.
