Manual MXR81.. – MOVIAXIS® Multi-Axis Servo Inverter 9
2.3 Designated use
The MXR supply and regenerative module is designed for integration in the device
network of the MOVIAXIS® MX multi-axis servo inverter.
MOVIAXIS® MX multi-axis servo inverters are units for use in industrial and commer-
cial systems to operate permanent-field synchronous AC motors and asynchronous
AC motors with encoder feedback. The motors must be suitable for operation with ser-
vo inverters. Do not connect other loads to the units without prior consultation of the
manufacturer.
MOVIAXIS® MX multi-axis servo inverters are intended for use in metal control cabi-
nets. These metal control cabinets represent the necessary degree of protection for
the application as well as the grounding over a large area required for EMC purposes.
When installed in machines, startup of the multi-axis servo inverters (i.e. start of desig-
nated operation) is prohibited until it is determined that the machine meets the require-
ments stipulated in Directive 2006/42/EC (Machinery Directive); observe EN 60204.
Startup (i.e. the start of designated use) is only permitted under observance of the
EMC directive (2004/108/EC).
Multi-axis servo inverters comply with the low voltage directive 2006/95/EC. The
harmonized standards of the EN 61800-5-1/DIN VDE T105 series in connection with
EN 60439-1/VDE 0660 part 500 and EN 60146/VDE 0558 are applied to these multi-
axis servo inverters.

4.3 Installing/removing the supply and regenerative module
Refer to the "MOVIAXIS® MX Multi-Axis Servo Inverter" operating instructions for a de-
scription of how to install a module in an axis system and how to remove it. Adhere to
these instructions when installing/removing a module.
4.4 Electrical installation
WARNING
Dangerous voltage levels may still be present inside the unit and at the terminal
strips up to 10 minutes after the complete axis system has been disconnected from
the supply system.
Severe or fatal injuries from electric shock.
• Disconnect the axis system from the supply system and wait 10 minutes before
removing the protective covers.
• After maintenance work, do not operate the axis system unless you have re-
placed the protective cover and the touch guard. Without protective cover, the
unit only has degree of protection IP00.

WARNING
A leakage current > 3.5 mA can occur during operation of the MOVIAXIS® MX multi-
axis servo inverter.
Severe or fatal injuries from electric shock.
• If the supply system lead is < 10 mm2, route a second PE conductor with the
same cross section as the supply system lead via separate terminals. Instead,
you can use a PE conductor with a copper cross section of ≥ 10 mm2 or alumi-
num ≥ 16 mm2.
• With an incoming supply line ≥ 10 mm2, it is sufficient to install a PE conductor
with a copper cross section ≥ 10 mm2 or aluminum ≥ 16 mm2.
• If an earth leakage circuit breaker can be used for protection against direct and
indirect contact, it must be universal current sensitive (RCD type B).
INFORMATION
Safe disconnection.
The unit meets all requirements for safe disconnection of power and electronics con-
nections in accordance with EN 61800-5-1. The connected signal circuits have to
meet the requirements according to SELV (Safe Extremly Low Voltage) or PELV
(Protective Extra Low Voltage) to ensure safe disconnection. The installation must
meet the requirements for safe disconnection.
4.4.1 Line contactor and cable cross sections
NOTICE
•Use a line contactor in utilization category AC-3 (IEC 158-1) or better. For in-
formation on the current carrying capacity, refer to chapter "Control section
of MXR supply and regenerative module" (→ 2 70).
• Line cable: Cross section according to nominal input current Iline at nominal
load.
4.4.2 Connecting braking resistor and emergency braking resistor
NOTICE
When using a braking resistor, observe the notes in chapter "Project Planning".
• SEW‑EURODRIVE recommends to connect the braking resistor as shown in chap-
ter "Wiring diagrams". Install switch F16 close to the unit network. If you use an un-
shielded cable for connecting switch F16 with the supply and regenerative module,
keep the length as short as possible. Preferably use a shielded power cable or
twisted individual lines as connection cable to the braking resistor. The cross sec-
tion must be selected depending on the nominal current of the braking resistor/
emergency braking resistor.
