Process adaptation
–
Almost every process can be adapted to the actual demand thanks to infinitely variable speed and torque control, which makes the process more
energy efficient. Depending on the application, energy savings of up to 70% can be achieved.
–
More energy-saving potential can be tapped in applications with periodic acceleration and deceleration through energy-efficient motion sequences.
Maximum acceleration, speed and braking deceleration are not always necessary.
Energy-saving function
–
The energy-saving function of MOVITRAC
®
LTE-B, LTP-B and MOVITRAC
®
B as well as MOVIDRVE
®
B offers advantages when the application has to
be operated in the part-load range and dynamic properties are not a main requirement when load changes occur.
–
The dynamic adjustment of the magnetization current enables the motor to be operated with optimum efficiency in every operating point. Energy
consumption is reduced by up to 30% depending on the application.
–
The energy-saving function ensures optimum efficiency of the drive especially in conjunction with an energy-efficient motor.
DC link coupling
–
By connecting the DC links of several inverters, regenerative energy of one drive can be used directly as motor energy in another drive.
–
This measure can reduce energy consumption from the supply system if the drive sequences are segmented and suitable travel profiles have been
selected.
–
MOVI-PLC
®
: In storage and retrieval systems, the decentralized controller allows for controlling the travel profile in an intelligent manner and in this
way achieves optimum energy coupling.
Regenerative power supply
–
A regenerative power supply unit feeds back the regenerative energy of a drive into the supply system.
–
The released braking energy is not dissipated via braking resistors but fed back into the supply system, which saves energy.
–
This is especially effective in hoists and storage and retrieval units.
Thermally controlled fans
–
The fans are switched on only when actual waste heat is generated. Not only does this lower energy consumption; it also increases the service life of
the fan.
