High-resolution encoder of 4194304 pulses/rev is used as the encoder of the
rotary servo motor compatible with the MELSERVO-J4 series. However, the
High-resolution encoder
encoder resolution of the rotary servo motor compatible with MR-J4-03A6-
RJ servo amplifiers will be 262144 pulses/rev.
Home position return is required only once, and not required at every power-

Advanced vibration
This function suppresses vibration at the arm end or residual vibration.
suppression control II
Machine resonance This is a filter function (notch filter) which decreases the gain of the specific
suppression filter frequency to suppress the resonance of the mechanical system.
When a load is mounted to the servo motor shaft, resonance by shaft torsion

Used when the regenerative option cannot provide enough regenerative
power.
Brake unit
Can be used for the 5 kW or more servo amplifier.
This is not available with MR-J4-03A6-RJ servo amplifiers.
Used when the regenerative option cannot provide enough regenerative
power.
Power regeneration
converter Can be used for the 5 kW or more servo amplifier.
This is not available with MR-J4-03A6-RJ servo amplifiers.
Used when the built-in regenerative resistor of the servo amplifier does not
have sufficient regenerative capability for the regenerative power generated.
Regenerative option
This is not available with MR-J4-03A6-RJ servo amplifiers.
Alarm history clear Alarm history is cleared.
Input signal selection ST1 (Forward rotation start), ST2 (Reverse rotation start), and SON (Servo-
(device settings) on) and other input device can be assigned to any pins.
