Mitsubishi Electric MR-JE-_A Instruction Manual page 5

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.
(2) Wiring
When removing the CNP1 connector of the MR-JE-40A to MR-JE-100A servo amplifier, remove the lead
wire of the built-in regenerative resistor from the CNP1 connector in advance.
Correctly and securely wire cables. Otherwise, the servo motor may operate unexpectedly.
Do not install a power capacitor, surge killer or radio noise filter (optional FR-BIF) between the servo
motor and the output side of the servo amplifier.
To avoid a malfunction of the servo motor, connect the wires to the correct phase terminals (U, V, and W)
of the servo amplifier and servo motor.
Connect the servo amplifier power output (U, V, and W) to the servo motor power input (U, V, and W)
directly. Do not let a magnetic contactor, etc. intervene. Otherwise, it may cause a malfunction.
Servo amplifier
This instruction manual uses connection diagrams for sink interface unless otherwise described.
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 for wrong axis to U, V, W, and CN2 of the servo amplifier connector may
cause a malfunction.
Configure a circuit to turn off EM2 or EM1 when the power supply is turned off to prevent an unexpected
restart of the servo amplifier.
