Compatible Motor Series
The MR-J2S-10B supports multiple Mitsubishi servo motor series for versatile machine configurations:
- HC-KFS - Low inertia, small capacity
- HC-MFS - Medium inertia, small capacity
- HC-SFS - Medium inertia, medium capacity
- HC-RFS - Medium inertia, high-speed
- HC-UFS - Ultra low inertia, small capacity
- HA-LFS - Medium inertia, large capacity
Sinusoidal PWM Control Benefits
Sinusoidal PWM control delivers smoother torque output by generating sinusoidal current waveforms in motor windings, reducing cogging and torque ripple at low speeds.
This results in improved surface finish for machine tools and reduced vibration at axis reversal points.
Built-In Dynamic Brake Safety
The integrated dynamic brake activates during servo-off or fault conditions, providing controlled stopping without external braking hardware. This eliminates the need for additional deceleration components in applications where coasting stops are unacceptable.
IP00 Cabinet Installation Requirements
The open structure design requires installation within a properly sealed and ventilated control cabinet. Adequate clearance above and below the unit is essential for maintaining thermal performance at rated operating temperatures.
Frequently Asked Questions
What motors are compatible with the MR-J2S-10B?
The drive is compatible with HC-KFS, HC-MFS, HC-SFS, HC-RFS, HC-UFS, and HA-LFS series Mitsubishi servo motors. Verify motor rated output matches the amplifier's capacity before installation.
Can the MR-J2S-10B be powered from a single-phase supply?
Yes, the drive accepts 1-phase 230VAC, 50/60Hz operation. Note that single-phase operation requires higher input current per phase - ensure supply circuit breakers and wiring are rated accordingly.
What does the "B" suffix in MR-J2S-10B mean?
The "B" designation indicates SSCNET (Serial Servo Communication Network) interface compatibility, requiring use with Mitsubishi motion controllers that support this high-speed serial bus.
Does the MR-J2S-10B require an external dynamic brake resistor?
No, the dynamic brake is built-in and requires no external resistor for standard applications. Verify capacity for high inertia loads or frequent emergency stops.
What protective functions are built into the MR-J2S-10B?
The drive includes comprehensive protection for overcurrent, overload, encoder fault, undervoltage, instantaneous power failure, overspeed, and excessive position error.
The MR-J2S-10B is a new original Mitsubishi product. Confirm motor compatibility, interface type, and cabinet thermal design before installation.
