1. To prevent electric shock, note the following
WARNING
Before wiring or inspection, turn off the power and wait for 15 minutes or more (20 minutes or more for
converter unit) until the charge lamp turns off. Then, confirm that the voltage between P+ and N-
(between L+ and L- for converter unit) is safe with a voltage tester and others. Otherwise, an electric
shock may occur. In addition, always confirm whether the charge lamp is off or not from the front of the
servo amplifier (converter unit).
Do not operate switches with wet hands. Otherwise, it may cause an electric shock.
2. To prevent fire, note the following
CAUTION
When you use an MR-J4 multi-axis servo amplifier, connecting an encoder for wrong axis to the CN2A,
CN2B, or CN2C connector may cause a fire.
3. To prevent injury, note the following
CAUTION
The servo amplifier (drive unit), converter unit heat sink, regenerative resistor, servo motor, etc. may
become hot while power is on or for some time after power-off. Take safety measures, e.g. provide
covers, to avoid accidentally touching the parts (cables, etc.) by hand.
4. Additional instructions
The following instructions should also be fully noted. Incorrect handling may cause a malfunction, injury,
electric shock, etc.
(1) Wiring
CAUTION
Wire the equipment correctly and securely. Otherwise, the servo motor may operate unexpectedly.
To avoid a malfunction of the servo motor, connect the wires to the correct phase terminals (U/V/W) of
the servo amplifier (drive unit) and the servo motor.
Connect the servo amplifier (drive unit) 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.

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 (drive unit).
