SV0512-3E
General-Purpose AC Servo
MELSERVO-J3
Servo Motor <HF-SP301, HF-SP421>
Medium inertia, medium capacity motor series 1000r/min,
HF-SP301 and HF-SP421, have been added to the
MELSERVO-J3 series. With the new rated output, 3kW and
4.2kW, the HF-SP series motors provide wider range of use.
The HF-SP301 and HF-SP421 are typically suitable for
material handling systems, robots or X-Y tables.
The HF-SP301 and HF-SP421 also conform to the global
standards (EN, UL, cUL standards).

Notes: 1. The power facility capacity varies depending on the power supply's impedance.
2. The regenerative braking frequency shows the permissible frequency for decelerating the motor without a load and the optional regeneration unit
from the rated speed to a stop.
3. Contact Mitsubishi if the load/motor of inertia moment ratio exceeds the value in the table.
4. The shaft-through portion is excluded.
5. The vibration direction is shown in the right-side diagram. The numeric value indicates the maximum value of the
component (commonly the bracket in the opposite direction of the motor shaft). Fretting of the bearing occurs easily when
X
Y
the motor stops, so maintain vibration to approximately one-half of the allowable value.
6. The amplifier software version compatible with HF-SP301 and HF-SP421 is as follows:
A type: Version B0 or above B type: Version A0 or above
7. MRZJW3-SETUP221E software version B1 or above is planned to be compatible with HF-SP301 and HF-SP421.
