Process adaptation
–
Almost every process can be adapted to the actual demand thanks to in²nitely variable speed and torque control, which makes the process more
energy-ef²cient. Depending on the application, this saves up to 70% of energy.
–
More energy-saving potential can be tapped in applications with periodic acceleration and deceleration through energy-ef²cient 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 ef²ciency in every operating point. The energy
consumption is reduced by up to 30% depending on the application.
–
The energy-saving function ensures optimum ef²ciency of the drive especially in conjunction with an energy-ef²cient 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 pro²les have been
selected.
–
MOVI-PLC
®
: In storage and retrieval systems, the decentralized controller allows for controlling the travel pro²le 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 as well as 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.
