Mitsubishi Electric MR-D30 Instruction Manual page 5

The servo amplifier and MR-D30 must be installed in a metal cabinet.
When fumigants that contain halogen materials such as fluorine, chlorine, bromine, and iodine are used
for disinfecting and protecting wooden packaging from insects, they cause malfunction when entering our
products. Please take necessary precautions to ensure that remaining materials from fumigant do not
enter our products, or treat packaging with methods other than fumigation (heat method). Additionally,
disinfect and protect wood from insects before packing products.
To prevent a fire or injury in case of an earthquake or other natural disasters, securely install, mount, and
wire the servo motor in accordance with the Instruction Manual.
(2) Wiring
Wire the equipment correctly and securely. Otherwise, the servo motor may operate unexpectedly.
Make sure to connect the cables and connectors by using the fixing screws and the locking mechanism.
Otherwise, the cables and connectors may be disconnected during operation.
Do not install a power capacitor, surge killer, or radio noise filter (optional FR-BIF(-H)) on the servo
amplifier output side.
To avoid a malfunction, connect the wires to the correct phase terminals (U/V/W) of the servo amplifier
and servo motor.
Connect the servo amplifier power output (U/V/W) to the servo motor power input (U/V/W) directly. Do
not let a magnetic contactor, etc. intervene. Otherwise, it may cause a malfunction.
Servo amplifier
The surge absorbing diode installed to the DC relay for control output signals should be fitted in the
specified direction. Otherwise, the emergency stop and other protective circuits may not operate.
When the cable is not tightened enough to the terminal block, the cable or terminal block may generate
heat because of the poor contact. Be sure to tighten the cable with specified torque.
Connecting a servo motor of the wrong axis to U, V, W, or CN2 of the servo amplifier may cause a
malfunction.
Configure a circuit to turn off EM2 or EM1 when the main circuit power is turned off to prevent an
unexpected restart of the servo amplifier.
To prevent malfunction, avoid bundling power lines (input/output) and signal cables together or running
them in parallel to each other. Separate the power lines from the signal cables.
