MELSERVO-J3 The ever-evolving new
■ Tact time improved with high-speed positioning
■ Flexible wiring
■ Machine performance improved with highly accurate operation
¡A high-resolution encoder 262144p/rev (18-bit) is mounted as a standard to realize stability even at low speeds.
¡Fluctuations in motor torque are reduced by reducing
the cogging torque.
¡The high speed (6000r/min) and
high-function speed frequency response
(900Hz) shorten positioning times.
¡The absolute encoder is standard equipment.
Home position return at each power on is not
necessary if a battery (MR-J3BAT) is mounted
on the servo amplifier.
<Servo amplifier>
¡Installation area is 40% smaller than
existing model (compared with 400W)
■ Improved environmental safety
The MELSERVO-J3 standard specifications conform to
overseas standards.
1. “Industry’s No. 1” indicated on pages 1 and 2 of this catalog is current as of August 2003.
2. This data is for the 750W.
3. Refer to “Servo Amplifier Specifications” and “Cautions Concerning Use” in this catalog for details.
4. Use an IP65 compatible cable when using the motor in an IP65 environment.

• Connectors have been adapted for the servo amplifier terminal
block thereby reducing the time required for wiring. Refer to
the section “Connections with peripheral equipment” in this
catalog for details regarding the connector.
IP65 is conformed as a standard for the servo motor HF-KP
series (excluding the shaft-through portion).
(Note 4)
IP67 is conformed as a standard for the servo motor HF-SP
series (excluding the shaft-through portion).
• The cable from the motor can be
led out in the direction of the
motor shaft or opposite direction
of the motor shaft according to
the selected cable. (HF-KP series)

(Note 2)
¡The connectors of the HF-SP series are smaller than
the existing HC-SFS series, so the user’s system is
even more compact.
