Overview of benefits:
- On-board, free of charge technology integrated in the unit offers many solution options even in combination with a standard PLC
-
Motion control functionality can be enhanced in steps and can “grow” with the machine (unit internal technology, MOVI-PLC® basic, MOVI-PLC ® advanced.)
-
Highly sophisticated features – Ethernet TCP/IP, USB, data storage, axis parameters/data auto re-load after axis replacement, Twin-CAN,…
-
Optimum combination options with all other SEW drive products, for tailor-made solutions
-
Saves time in implementing motion control tasks, thanks to integrated functions
-
Quick and easy startup and operation thanks to graphical and user-guided interfaces
- Multi-motor operation eliminates the need for additional inverters, e.g. for alignment tasks
-
Offers maximum dynamic response and control qualities for highly dynamic tasks
-
Requires little installation space – while enabling integral, simple convection cooling and high power density (250% overload capacity)

Master modules |
||
|---|---|---|
 |
Master modules are the “brain” of any axis system. Depending on the variant, the entire axis system is addressed by a non-SEW
controller or by a MOVI-PLC® controller from SEW-EURODRIVE.
The MOVIAXIS® master module is available in three variants:
|
|
|
1) On request

|
Axis modules |
|
|---|---|
 |
Axis modules either communicate directly with an external controller via the integrated system buses and fieldbus option cards
or are controlled centrally via a master module of one of the three types.

Supply modules |
|
|---|---|
 |
The supply modules provide the connected axes with power. They have a high overload capacity and regulate the regenerated
power according to the unit variant.
Features:

|
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 fluctuations or variations in the supply input voltage. Power is taken from the supply system with cos φ = 1 as standard. It also feeds back excess energy into the supply system sinusoidally, avoiding line harmonics almost completely. This means
that sensitive electronic components operated on the same supply system are subject to significantly less interference. The MXR also offers 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 other MXP supply
modules. Braking energy is “moved” temporarily and utilized again during the next acceleration process. This minimizes the average amount of energy taken from the supply system and reduces or completely prevents the heating of the control cabinet. This reduces costs for the control system climate control and saves valuable mounting space. |

|
MXP81 compact supply modules |
|
|---|---|
|
For machines with a particularly compact design and fast cycle times, the compact power supply modules meet demands for minimum installation effort, small housing dimensions and energy buffering to prevent/reduce losses and heat dissipation. In this supply module, a braking resistor is integrated in addition to a storage module. Amounts of energy that exceed the storage capacity are automatically dissipated. |

In addition to energy consumption, which is already optimized for synchronous servomotors due to their operating principle,
the handling of the braking energy is key.
the handling of the braking energy is key.
During the development of MOVIAXIS®, this topic has been paid special attention. 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.
