Mitsubishi Electric MR-JE-*C Instruction Manual page 5

The servo amplifier 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 from occurring 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
Before removing the CNP1 connector of MR-JE-40C to MR-JE-100C, disconnect the lead wires of the
regenerative resistor from the CNP1 connector.
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) 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 connection diagrams in this instruction manual are shown for sink interfaces, unless stated
otherwise.
The surge absorbing diode installed to the DC relay for control output 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.
