Assisting upgrades fromMELSERVO-HA(N) to
MELSERVO-J3-A

Replace

MR-HA(N) Series with
MR-J3-A Series
using existing wiring!
The MR-HA(N) renewal tool is a tool used to replace an existing MR-HA(N) Series servo
amplifier with the MR-J3-A Series servo amplifier.
This tool is configured of a renewal kit which provides compatibility of existing installation
dimensions, cables, and terminal blocks, and a motor conversion cable used when replacing the
MR-H servomotor with a MR-J3 servomotor.

Features● An existing MR-H Series servomotor can be run with an MR-J3-A Series servo amplifier (standard product)*1.
● Wiring work can be reduced by using the existing wiring.
● Renewal kit can be mounted using existing mounting holes.
● Slide mechanism on renewal kit allows available space to be used effectively.
● Renewal kit is compatible with detector pulse open collector output, a function lacking when replacing
MR-HA(N) Series servo amplifier with MR-J3-A Series servo amplifier.
● Renewal tool allows renewal to be carried out in stages, such as primary to secondary replacement.
*Supported from software version C6 and higher.
Primary replacement : Replace only servo amplifier
Secondary replacement : Replace servomotor after replacing servo amplifier
Package replacement : Replace servo amplifier and servomotor together* The servomotor cannot be replaced as an isolated unit.

: Compatible, Δ : Conditionally compatible, : Incompatible* 1. The servo amplifier capacity increases.
in the model indicates the cable length.
* 2. The servo amplifier capacity decreases.
in the model is “A1” or “A2”. (A1: Load side connection, A2: Counter load side connection)* 3. The servomotor capacity increases.
* 4. When replacing the servomotor, check the capacity selection again when selecting the replacement motor.
* 5. When replacing a motor with brakes in the secondary stage or as a package, the magnetic brake cable must be newly laid.
* 6. Package replacement is recommended as the servo amplifier must be replaced again after secondary replacement.
* 7. Package replacement is recommended as the renewal kit (model: SC-HAJ3KT06K) must be replaced again after secondary replacement.
* 8. With secondary replacement or package replacement, the servo amplifier capacity will decrease and change the servo amplifier’s outline shape. A special renewal kit is required in this case.
* 9. With secondary replacement or package replacement, the servo amplifier capacity will increase and greatly change the servo amplifier’s outline shape and terminal block position, etc., so therenewal kit cannot be used.
*10. Compatible with the rated speed 2000r/min servomotor. (The speed range and torque characteristics are satisfied.)*11. When using the renewal kit, the dimensions will increase compared to the existing MR-H servo amplifier.
*12. When replacing the HA-FE or HA-FF motor with the HF-KP motor, or the HA-UH motor with the HC-UP or HF-SP motor, the flange dimensions and shaft end dimensions are not compatible,
so the installation section and the coupling with the servomotor shaft, such as the coupling and pulley must be changed. (Consult with Mitsubishi Electric if there are any difficulties.)*13. Consult with Mitsubishi for the secondary replacement and package replacement servo amplifier, servomotor and motor side conversion cable.
*14. With secondary replacement or package replacement, the motor flange angle dimensions will increase by 6mm, and the step on the motor body side of the output shaft will differ, so replacement
may not be possible in some cases.
*15. When replacing the HA-SH motor with the HF-SP motor, the motor inertia will be approx. 0.5 to 0.7 higher than the HA-SH motor. Pay attention to the load moment of inertia ratio.
Replacement may not be possible depending on the existing equipment.
In addition, when replacing the HA-LHK motor with the HA-LPK motor, the motor inertia will be approx. 0.75 to 0.9 higher than the HA-LHK motor.
Pay attention to the load moment of inertia ratio. Replacement may not be possible depending on the existing equipment.
*16. Use the Mitsubishi motor power cable (model: MR-PWS1CBLM--L, MR-PWS2CBL03M--L) for the replacement motor (HF-KP, HF-MP) power conversion cable.
*17. Use the Mitsubishi motor magnetic brake cable (MR-BKS1CBLM--L, MR-BKS2CBL03M--L) for the replacement motor (HF-KP, HF-MP) brake conversion cable.
*18. Incorporated in the power conversion cable (SC-SAJ3PW2KC1M1).
*19. When using an existing model with the absolute position detection system, it shall be handled as a special product.
*20. The replacement servo amplifier is supported from software version C6 and higher. Consult with Mitsubishi Electric for orders.
*21. Purchase from Mitsubishi Electric.
*22. With secondary replacement or package replacement, the servomotor cooling fan will change from single-phase to 3-phase requiring new wires to be laid.
*23. When replacing the motor, the crimp terminals for existing power cables must be changed. (UVW terminal screw size HA-LH15K2, 22K2: M6, HA-LP15K2, 22K2: M8).
*24. When replacing the motor with reduction gears, the installation section and reduction ratio may differ depending on the motor. Consult with Mitsubishi before replacing.

MR-H22KA(N)Precautions for Replacement
When replacing the MR-HA(N) Series with the MR-J3-A Series, refer to the "Guide for Replacing MELSERVO-HA(N) Series with
MR-HA(N) Renewal Tool (X903090601)" available on the Mitsubishi Electric System & Service web site for information.
When several units are installed in a row, replacement may not be possible depending on the pitch between the servo amplifiers,models or number of units.
Depending on the installation state, measures against noise may be required when making the replacement. Refer to the “Guide for
Replacing MELSERVO-HA(N) Series with MR-HA(N) Renewal Tool (X903090601)” available on the Mitsubishi Electric System &Service web site for information.
Take the cable life into consideration when using existing cables. If the cable is worn, it should be replaced with a new one.
The conversion cable is not a high-flexible service part. Always fix the cable during use.
Consult with Mitsubishi when using a detector cable longer than 50m. (For secondary replacement and package replacement.)
The standard MR-J3 servomotor is not provided with an oil seal. If the existing MR-H servomotor is provided with an oil seal, pleasetake care when selecting the replacement mode. Consult with Mitsubishi if a servomotor with oil seal is required.
Depending on the machine conditions (inertia, load, etc.), the servo amplifier's capacity may be insufficient after renewal. Carefully
consider the capacity when replacing the models.
For the regenerative option, recalculate the regeneration capability, etc., and select the capacity. Prepare a regenerative option if
required.
The dynamic brakes provided with the replacement MR-J3-A servo amplifier as a standard can be used, but the coasting amountmay differ according to the dynamic brake’s characteristics.
Consult with Mitsubishi if the existing MR-HA(N) servo amplifier or motor is a special part.
Functions may be limited depending on the working conditions of existing devices.
The analog torque limit command (-) TLAN signal cannot be used with the renewal kit.
When using the renewal kit, the number of usable input signals is limited during the speed control mode.
The MR-H option card function and communication function are not supported.

Mitsubishi Electric System & Service provides total support, ranging from system review, program conversion, local work and system startup,for our customers replacing the MELSERVO-HA(N) with the MELSERVO-J3-A Series. Please contact us for more information.
