System description
1.3.8 MXP power supply modules
• Cover a wide range of power ratings with 4 finely graded performance classes: 10 /
25 / 50 / 75 kW
• Wide range of supply system voltages for universal application: AC 3 × 380 – 500 V,
50/60 Hz
• High drive dynamics with smaller line connection components due to the high over-
load capacity of 250 % of the nominal power for maximum 1 s
• Minimized THD/harmonics values and reactive power consumption due to optimized
charging currents and high effective current percentage
• Time-saving and error-proof due to automatic address assignment for all axes con-
nected to the CAN1/EtherCAT®system bus
• Informative and easy due to 7-segment display for user-friendly visualization of op-
erating and error states of the power supply module
• 4-quadrant capability due to the standard brake chopper integrated in the power sup-
ply module.
Unit data
The power supply module provides energy to up to 8 axis modules as standard. It con-
trols the regenerated energy via a braking resistor or via DC link storage to separate
capacitor or buffer modules.
You can connect a maximum of 10 axis modules. In this case, please contact SEW-
EURODRIVE.
Battery-powered supply modules are available for special applications. Contact SEW-
EURODRIVE in such cases.

System description
1.3.9 MXP81 compact power supply module 10 kW
• Compact size due to the integration of the braking resistor, brake chopper, and en-
ergy buffer in the housing.
• Saves energy by storing up to 250 Ws and dynamically re-using this energy.
• Optimized and flexible installation due to the integration of all elements that are im-
portant for operation. This means additional wiring of braking resistors is no longer
necessary. If the internal braking resistor is used to capacity, you can connect a
larger, external braking resistor as an option
• Wide range of supply system voltages for universal application: AC 3 × 380 – 500 V,
50/60 Hz
• High drive dynamics with smaller line connection components due to the high over-
load capacity of 250 % of the nominal power for maximum 1 s
• Minimized THD/harmonics values and reactive power consumption due to optimized
charging currents and high effective current percentage
• Time-saving and error-proof due to automatic address assignment for all axes con-
nected to the CAN1 or EtherCAT®system bus
• Informative and easy due to 7-segment display for user-friendly visualization of op-
erating and error states of the power supply module
• 4-quadrant capability due to the standard brake chopper integrated in the power sup-
ply module.
Unit data
The compact power supply module provides energy to up to 8 axis modules as stan-
dard. It controls the regenerated energy via an integrated braking resistor or via an ex-
ternal braking resistor and DC link storage to an integrated energy buffer.

Benefits and key features of MOVIAXIS®
System description
1.3.10 MXR80 supply and regenerative modules (sinusoidal)
• Optimum logistics, because one unit covers two performance classes (50 kW or 75
kW)
• Wide range of supply system voltages for universal application: AC 3 × 380 – 480 V,
50/60 Hz
• High drive dynamics with smaller line connection components due to the high over-
load capacity of 200% of the nominal power for maximum 1 s
• Only effective power consumption in nominal operation, i.e. cosφ= 1
• Minimal THD values and reactive power consumption due to sinusoidal current con-
sumption and regeneration
• Time-saving and error-proof due to automatic address assignment for all axes con-
nected to the CAN1/EtherCAT®system bus
• Informative and easy due to 7-segment display for user-friendly visualization of op-
erating and error states of the power supply module
• Information about the current energy flow and regenerative energy via service pa-
rameter
• Better utilization of the motor power due to increased DC link level of DC 750 V
• Necessary transformer power is minimized by optional EcoLine filter
• Intelligent and communicative due to option cards for EtherCAT®, PROFIBUS and
SBusplus for seamless system integration
• Safe in case of a power failure due to standard integrated brake chopper for connect-
ing an emergency braking resistor.
The supply and regenerative modules are available with sinusoidal or block-shaped en-
ergy regeneration.
For detailed information about MXR, refer to the manuals "Supply and Regenerative
Module - MXR80" and "Supply and Regenerative Module - MXR81".
Supply and regenerative modules provide energy to up to 8 axis modules as standard.
They feed back energy to the power grid via sinusoidal regeneration. A brake chopper
is integrated as standard, e.g. for emergency braking operations.

System description
1.3.11 MXR81 supply and regenerative modules (block-shaped)
• 2 performance classes with 50 kW and 75 kW in 2 frame sizes
• Wide range of supply system voltages for universal application: AC 3 × 380 – 480 V,
50/60 Hz
• High drive dynamics with smaller line connection components due to the high over-
load capacity of 250 % of the nominal power for maximum 1 s
• Only effective power consumption in nominal operation, i.e. cosφ= 1
• Cost-optimized solution for grids with constant voltage and frequency
• Time-saving and error-proof due to automatic address assignment for all axes con-
nected to the CAN1/EtherCAT®system bus
• Informative and easy due to 7-segment display for user-friendly visualization of op-
erating and error states of the power supply module
• Information about the current energy flow and regenerative energy via service pa-
rameter
• Intelligent and communicative due to option cards for EtherCAT®, PROFIBUS and
SBusplus for seamless system integration
• Safe in case of a power failure due to standard integrated brake chopper for connect-
ing an emergency braking resistor.
• Regenerative operation is activated automatically. The output stage is activated in
actual regenerative operation, i.e. it is inhibited during motoring operation and stand-
still. Grid disturbances, reactive power, and supply transformer heating are reduced
to a minimum.
• Emergency operation with braking resistor can easily be activated, e.g. for working
within an isolated system or when using a UPS.
The supply and regenerative modules are available with sinusoidal or block-shaped en-
ergy regeneration.
For detailed information about MXR, refer to the manuals "Supply and Regenerative
Module - MXR80" and "Supply and Regenerative Module - MXR81".
Supply and regenerative modules provide energy to up to 8 axis modules as standard.
They feed back energy to the power grid via block-shaped regeneration. A brake chop-
per is integrated as standard, e.g. for emergency braking operations.
