Multi-Axis Servo Inverter
MOVIAXIS® – Saving Energy in Many Ways
During the development of MOVIAXIS®, a special focus was on the topic of energy consumption. In addition to energy consumption, which for synchronous servomotors is already optimized due to their operating principle, the handling of the braking energy is key. Options for re-using the braking energy were developed in order to significantly improve the overall energy balance of a drive solution and to save costs.

Technology and motion control functions that meet the highest standards, combined with maximum dynamics, energy efficient components and global availability - All this is provided by SEW-EURODRIVE's modular system of highly dynamic servo drives. MOVIAXIS® is the perfect multi-axis servo inverter for drive and automation solutions that save time, costs and effort.

Energy saving properties
MXR regenerative power supply modules
The MXR regenerative power supply module has been developed for complete regeneration of braking energy.
It provides a constant, controlled DC link voltage and drive performance regardless of variations in the line input voltage.
Power is taken from the supply system with cos φ = 1 as standard.
The module also feeds back excess energy into the supply system sinusoidally, avoiding line harmonics almost completely.
Sensitive electronic components operated on the same supply system are subject to significantly less interference.
The MXR offers diverse additional service and operation features, such as information about effective power or an integrated load counter.

MXC storage modules
The optional MXC storage modules were developed for storing energy temporarily. They can be connected to all MXP supply modules.
Braking energy is "stored" here temporarily and utilized again during the next acceleration process.
This dramatically minimizes the average amount of energy extracted from the supply system and reduces or completely prevents the heating of the control cabinet due to energy dissipation in braking resistors. Any follow-up costs related to this are also reduced significantly, e.g. for possibly necessary cooling and climate control measures.

MXP81 compact power supply module
The compact supply modules fulfill the requirements for reduced installation effort especially for machines with a compact design and fast cycle times. The small housing dimensions and the energy buffer prevent and reduce losses and waste heat.
In these supply modules, a braking resistor is integrated in addition to the storage module. Amounts of energy that exceed the storage capacity are automatically dissipated.
