AC Servo

Mitsubishi General-purpose AC Servo
Renewal Tool

Helping transitions from MR-CuA Series toMR-JN-uA Series.

Features Complete transitions in a short time by using existing wiring and mounting holes.
		 The renewal tool allows upgrades to be carried out in stages, such as primary to secondary upgrade.
		 Standard parts are used for the replacement amplifier and motor.
		 The MR-CuA servo amplifier motor can be controlled with the standard MR-JN-uA servo
amplifier.

Precautions for Replacement
 Note that even when this renewal tool is used, some MR-CuA servo functions may not be 100% compatible.
 An open space of 205mm or more in depth is required to upgrade from the existing MR-CuA servo
amplifier to the MR-JN-uA servo amplifier.
 A separate 24V DC (current capacity 500mA or more) is required for the control circuit when making thereplacement. Use a circuit protector when connecting the control circuit power. Refer to the back pagefor recommended parts.
 Refer to the “Guide for Replacing MELSERVO-CuA(N) Series with MR-CuA(N) Renewal Tool
(X90311320)” available on the Mitsubishi Electric System & Service web site for details on upgradingfrom the MR-CuA Series to the MR-JN-uA Series.
 Depending on the situation, it may be necessary to change the existing wiring as a noise
countermeasure when using the positioning unit (mode: FX-1GM, FX-20GM, etc.).
 The initialization time after power ON differs for the MR-CuA servo amplifier and MR-JN-uA servo
amplifier, so it may be necessary to change the program in existing systems.
 The renewal tool model may differ according to the existing servo amplifier’s control method.

A separate 24V DC (current capacity 500mA or more) is required for the control circuit when making the replacement. Use a reinforced insulated power supply for the 24V DC control circuit power. Do not use a power sourcethat takes more than one second for the output voltage to start. A circuit protector must be used when connecting the control circuit power.

Opposite to loadside leadAn open space of 205mm or more in depth is required to upgrade from the existing MR-C servo amplifier to the MR-JN servo amplifier.
A separate 24V DC (current capacity 500mA or more) is required for the control circuit when making the replacement. Use a reinforced insulated
power supply for the 24V DC control circuit power. Do not use a power source that takes more than one second for the output voltage to start.
A circuit protector must be used when connecting the control circuit power. Refer to the back page for recommended parts.
*3. The compatible range of the special shaft differs for the HC-PQ motor and HF-KN/KP motor. Refer to the [Comparison of servo motor special shaft
support] above for details.
Contact Mitsubishi Electric Corp. for details on the items indicated with “”.
*4. The mounting flange and shaft dimensions are not interchangeable during secondary replacement or package replacement. The mounting section
and the coupling section with the servo motor shaft, such as the coupling pulley must be changed.
*5. The existing regeneration option cannot be used when replacing. Calculate the regeneration capacity and select the capacity again. If necessary,
use a regeneration option. Refer to the MR-JN-A Servo Amplifier Technical Materials for details on selecting the capacity.
*6. The mounting flange side and deceleration rate differ for secondary replacement and package replacement. Note that the mounting section must bechanged, and the system must be adjusted.
*7. Purchase from Mitsubishi Electric Corp.
*8. The following items are not supported.
• 5V pulse train specification servo amplifier (model: MR-CA-L).
• Input signal 5V voltage function.
*9. When using with the position control method, confirm that the detector Z-phase pulse signal (OP) is assigned to the CN1-4 pin.
The existing wiring must be changed if the signal is not assigned.
*10. When using the existing servo motor with a torque exceeding 300%, the capacity must be increased for the replacement servo amplifier and servomotor.
