Input Power Supply Circuit - Mitsubishi Electric MR-J4-10A(-RJ) Instruction Manual

18. MR-J4-03A6(-RJ) SERVO AMPLIFIER
The items in the following table are the same as those for MR-J4-_A_(-RJ) servo amplifiers of 100 W or
more. Refer to the section of the detailed explanation field for details.

18.3.1 Input power supply circuit

CAUTION
Detailed explanation of signals
Forced stop deceleration function
Servo motor with an electromagnetic brake
Connect a circuit protector between the power supply and power supply voltage
input terminals (24/PM) of the servo amplifier, in order to configure a circuit that
shuts down the power supply on the side of the servo amplifier's power supply. If
a circuit protector is not connected, continuous flow of a large current may cause
a fire when the servo amplifier malfunctions.
Use ALM (Malfunction) to switch main circuit power supply off. Not doing so may
cause a fire when a regenerative transistor malfunctions or the like may overheat
the built-in regenerative resistor.
Check the servo amplifier model, and then input proper voltage to the servo
amplifier power supply. If input voltage exceeds the upper limit of the
specification, the servo amplifier will break down.
Connecting a servo motor of the wrong axis to U, V, W, or CN2 of the servo
amplifier may cause a malfunction.
POINT
EM2 has the same function as EM1 in the torque control mode.
