The built-in regenerative resistor is not provided for the MR-J4-10A.
For 1-phase 200 V AC to 240 V AC, connect the power supply to L1 and L3. Leave L2 open.
For power supply specifications, refer to section 1.3.
Servo amplifiers MR-J4-70A or greater have a cooling fan.
MR-J4 servo amplifier has P3 and P4 in the upstream of the inrush current suppression circuit. They are different from P1 and
P2 of MR-J3 servo amplifiers.
Available in the future.
