[Appendix 2] Introduction to Renewal Tool
<Precautions>
Note 1. The renewal tool is compatible with the following capacity:
• General-purpose interface/SSCNET interface: 0.1 kW to 0.4 kW (100 V), 0.1 kW to 37 kW (200 V), and 0.6 kW to 55 kW
(400 V)
• Built-in positioning: 0.1 kW to 0.4 kW (100 V) and 0.1 kW to 7 kW (200 V)
2. Note that the coasting distance is different between the MR-J2S servo amplifier and the MR-J4 servo amplifier.
When DB assignment function is used for a servo amplifier of 11 kW or more, set the parameter as follows.
For general-purpose interfaces, set [Pr. PD27] as "0006".
For SSCNET interfaces, set [Pr. PD08] as "0006".
3. When replacing, some models cannot use the existing regenerative option. Provide regenerative options as necessary by
reselecting the capacity, including calculating the regenerative ability again. Refer to Chapter 7.
4. A separate 24 V DC power supply (current capacity: 80 mA or more) for the interface is required when the internal 24 V
DC power supply for the interface is used for the MR-J2S servo amplifier. Must be provided by the customer. (Not included
with the renewal tool.)
5. There is no restart function in the MR-J4 servo amplifier during momentary power interruption. When replacing, if undervoltage
(AL 10.1 or AL 10.2) is generated by instantaneous power failure, reset the alarm (turn off the power once) and restart.
6. Please note that if the renewal kit is used, it is necessary to remove the renewal kit when replacing the servo amplifier cooling
fan.
7. When replacing, it is necessary to adjust the command pulse train logic setting between the positioning module and the servo
amplifier. For details, refer to Part 2 Section 3.7.
8. This is the time between power-on and servo-on reception. Due to different reception times, sometimes review of the external
sequence is necessary upon replacement.
9. When replacing to the MR-J2S servo amplifier, it is necessary to set the parameters to EM1 (DB stop) (at the time of shipment
of the MR-J4 servo, the parameter is set to EM2 (deceleration stop)). For details about parameter settings, refer to Part 2 for
general-purpose interfaces, Part 3 for SSCNET interfaces, and Part 4 for built-in positioning.
For built-in positioning, it is not able to change the assignment of the forced stop signal (CN1-42 pin) by the parameter in the
MR-J4 servo amplifier. When the assignment of the EMG signal in the existing MR-J2S servo amplifier has been changed, the
existing wiring change becomes necessary.
10. This is the time until alarm signal output. Due to different reception times, sometimes review of the external sequence is
necessary upon replacement. Refer to Part 7 for details.
11. Note that the renewal tool is not compatible with alarm code output.
12. Upon replacement, it is necessary to set the parameter for the encoder output pulses.
For details about parameter settings, refer to Part 2 for general-purpose interfaces, Part 3 for SSCNET interfaces, and Part 4
for built-in positioning.
13. When replacing, a separate communication cable (USB cable: MR-J3USBCBL3M) is required to connect between the servo
amplifier and the personal computer.
14. The renewal tool is not compatible with RS-422/232C serial communication functions.
15. Please note that the command pulse frequency and the droop pulse output unit are different.
16. Due to differences in servo motor maximum speed, for secondary and simultaneous replacement the output value of the
monitor (servo motor speed) is different from that of the existing servo amplifier.
Note that it is required to change the program when using monitor output with existing equipment.
17. In order to connect between the SSCNET conversion unit (model: MR-J4-T20) and the personal computer, both the existing
communication cable (model: MR-CPCATCBL3M) and the junction cable for RS-232C (model: MR-J4T20CH00) are required.
18. Please note that the control circuit power supply of the 400 V servo amplifier (7 kW or less) between MR-J2S and MR-J4 are
different.
19. Not included with the renewal tool for 400 V. Please note that it is required to be laid again when the terminal size etc. are
different.
20. When replacing a converter unit, a new cable for CN1 is required to be laid.
21. A renewal kit and mounting attachment are not compatible with a heat sink outside mounting attachment of the MR-J2S servo
amplifier.
22. The renewal tool is not compatible with the DI/DO combination function.
