Mitsubishi Electric MELSERVO-J2S Series Manual page 18

<Precautions>
Note 1. The renewal tool is compatible with 0.1 to 22 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 A types, set PD27 as "0006".
For B types, set 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. For details, refer to Part 7 of the "Guide for
Replacing MR-J2S / J2M L (NA) 03092" issued by Mitsubishi Electric Corporation.
4. A separate 24 V DC power supply (current capacity: 80 mA or more) for the interface is required when the internal
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. If the renewal kit is used, it is necessary to remove the renewal kit when replacing the servo amplifier cooling fan. Take care.
7. When replacing, it is necessary to adjust the command pulse train logic setting between the positioning module and the servo
amplifier. For details, see section 2.6.6.
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. For details, see section 2.6.4.
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 information regarding detailed parameter settings,
refer to the "Guide for Replacing MR-J2S / J2M L (NA) 03092" issued by Mitsubishi Electric Corporation.
• For A Type: Part 2, Section 3.5
• For B Type: Part 3, Section 3.7
10. This is the time until alarm signal output. Due to different reception times, sometimes review of the external sequence is necessary
upon replacement. For details, see section 2.6.4.
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 information regarding detailed parameter settings, refer to the "Guide for Replacing MR-J2S / J2M L (NA) 03092"
issued by Mitsubishi Electric Corporation.
• For A Type: Part 2, Section 3.5
• For B Type: Part 3, Section 3.7
13. Due to differences in motor maximum speed, for secondary and package replacement the output value of the monitor (motor
speed) is differentfrom that of the existing amplifier.
Note that it is required to change the program when using monitor output with existing equipment.
14. 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 RS232C (model: MR-J4T20CH00) are required.
Please purchase the Mitsubishi Electric Corporation item.
15. Please note that the command pulse frequency and the droop pulse output unit are different.
16. When replacing, a separate communication cable (USB cable: MR-J3USBCBL3M) is required to connect between the servo
amplifier and the personal computer. Please purchase the Mitsubishi Electric Corporation item.
17. The renewal tool is not compatible with RS-422/232 serial communication functions.

• For A Type: Part 2, Section 3.5
• For B Type: Part 3, Section 3.7
For the MR-J4-_B-RJ020 servo amplifier, if the HG series servo motor is used, the encoder resolution per rotation of the servo
motor is not 4194304 pulses/rev but becomes 131072 pulses/rev.
