The MOVITRAC® 31C series frequency inverters are microprocessor inverters with sinusoidal PWM modulation. They are used to control the rotation of gearmotors and standard motors with nominal powers from 0.55 kW to 55 kW (0.75 hp to 75 hp). The units are connected directly to the three-phase AC network (3 x 200 ... 240 VAC and 3 x 380 ... 500 VAC at 50 or 60 Hz).
The output voltage is three-phase and variable up to the level of the input voltage with a proportional increase in the output frequency up to the inflection frequency adjustable between 50 Hz and 120 Hz (option 3: 5 ... 400 Hz). This function allows the three-phase induction motor to operate with constant torque up to the inflection frequency and with constant power above the inflection frequency. A continuous reduction of the current limitation above the selected bending frequency, guarantees the protection of the three-phase AC motor against blocking in the constant power range.
All electronic inputs and outputs are electrically isolated from the power supply. The electronic circuits are powered by a switched source, independent of the input frequency and operating above the input voltage range (80 VAC -10% ... 500 VAC + 10%). MOVITRAC® 31C inverters operate with menus similar to those of the supplied and tested MOVITRAC® 3000 inverters. The individual functions are determined for the same parameters. Therefore, the same MC_SHELL program can be used to program both MOVITRAC® 31C and MOVITRAC® 3000 via the PC. MOVITRAC® 31C parameters can also be adjusted and edited using the FBG 31C manual controller. In addition to the main settings menu, a short menu with the most important functions is also offered. The overload procedure and the automatic motor measurement function allow all components of the drive to be optimized. MOVITRAC® 31C frequency inverters are generally available as 4-quadrant units with integrated brake chopper.
The MOVITRAC® 31C base unit can be equipped with several options to suit the requirements of each application (except for size 0: MOVITRAC® 31C005 / 31C007 / 31C011 / 31C014, see also "Standard data").
