Specifications

EZ Motion E series SUPER
29
• The optional regeneration unit becomes hot (the
temperature rise of 100°C or more) with frequent use. Do
not install within flammable objects or objects subject to
thermal deformation. Take care to ensure that electrical
wires do not come into contact with the unit.
• Carefully consider the cable clamping method, and make
sure that bending stress and the stress of the cable’s own
weight are not applied on the cable connection section.
• If using in an application where the servo motor moves,
select the cable bending radius according to the required
bending life and wire type.
• Fix the power supply and encoder cables led out from the
servo motor onto the servo motor so that they do not
move. Failure to do so may result in disconnections.
Do not modify the connector or terminals, etc., on the end
of the cable.
Grounding
• Securely ground to prevent electric shocks and to stabilize
the potential in the control circuit.
• To ground the servo motor and servo amplifier at one
point, connect the grounding terminals of each unit, and
ground from the servo amplifier side.
• Faults such as a deviation in position may occur if the
grounding is insufficient.
Wiring
• When a commercial power supply is applied to the
amplifier’s output terminals (U, V, W), the amplifier will be
damaged. Before switching the power on, perform
thorough wiring and sequence checks to ensure that there
are no wiring errors, etc.
• When a commercial power supply is applied to the motor’s
input terminals (U, V, W), the motor will be damaged.
Connect the motor to the amplifier’s output terminals (U, V,
W).
• Match the phase of the motor’s input terminals (U, V, W) to
the amplifier’s output terminals (U, V, W) when connecting.
If they are not the same, the motor control cannot be
performed.
• For position or speed control mode, connect the stroke
end signals (LSP, LSN) to the common terminal (SG). If the
signals are invalid, the motor will not rotate.
• Connect P and D on the power supply connector (CNP1)
when using the built-in regenerative resistor.
Factory settings
• All available motor and amplifier combinations are
predetermined. Confirm the models of the motor and
amplifier to be used before installation.
• Select the control mode, motor series and motor capacity
with the parameter No. 0.
• For MR-E-MA-KH003, position control mode is set as
default. Change the setting value when using speed
control mode.
• For MR-E-MAG-KH003, speed control mode is set as
default. Change the setting value when using torque
control mode.
• Change parameter No. 0 when using the optional
regeneration unit. The optional regeneration unit is
disabled as the default, so the parameter must be
changed to increase the regeneration performance.
To ensure safe use
• To use the products given in this catalog properly, always
read the “Installation Guide” and “MR-E-MA/AG-KH003
INSTRUCTION MANUAL” before starting to use them.
• These products have been manufactured as a general-
purpose part for general industries, and have not been
designed or manufactured to be incorporated in a device
or system used in purposes related to human life.
• Before using the products for special purposes such as
nuclear power, electric power, aerospace, medicine,
passenger movement vehicles or underwater relays,
contact Mitsubishi.
• These products have been manufactured under strict
quality control. However, when installing the product
where major accidents or losses could occur if the
product fails, install appropriate backup or failsafe
functions in the system.
Cautions concerning use
Transport and installation of motor
• Protect the motor or encoder from impact during handling.
When installing a pulley or coupling, do not hammer on the
shaft. Impact can damage the encoder. For a motor with a
key, install a pulley or coupling with the screw of shaft-end.
Use a pulley extractor when taking off the pulley.
• Do not apply a load exceeding the tolerable load onto the
servo motor shaft. The shaft could break.
Installation
• Avoid installation in an environment in which oil mist, dust,
etc. are in the air. When using in such an environment,
enclose the servo amplifier in a sealed panel. Protect the
motor by furnishing a cover for it or taking similar measures.
• Mount the amplifier vertically on a wall.
• When installing several amplifiers in a row in a sealed
panel, leave 10mm or more open between each amplifier.
When installing several units in a row, leave 100mm or
more open in the upward direction, and 40mm or more in
the downward direction, or install a fan to prevent heat
from accumulating.
When using one amplifier, leave 40mm or more open in the
upward and downward directions.
• For a single motor, the motor can be mounted horizontally
or vertically. When mounting vertically (shaft-up), take
measures on the machine side to ensure that oil from the
gear box does not get into the motor.
• Do not touch the servo motor during or after operation until
it has had sufficient time to cool.
The motor can be very hot, and severe burns may result
from touching the motor.
