Note 1. Refer to section 1.3.1 for the power supply specification.
2. 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.
3. Use an external dynamic brake for this servo amplifier. Failure to do so will cause an accident because the servo motor does
not stop immediately but coasts at an alarm occurrence for which the servo motor does not decelerate to stop. Ensure the
safety in the entire equipment. For alarms for which the servo motor does not decelerate to stop, refer to section 6.1.
4. The power factor improving AC reactor can also be used. In this case, the power factor improving DC reactor cannot be used.
When not using the power factor improving DC reactor, short P3 and P4.
