[Appendix 2] Introduction to Renewal Tool
(2) Secondary replacement (when replacing the servo motor after replacing the servo amplifier)/
Simultaneous replacement (when replacing the servo amplifier and the servo motor simultaneously)
For 3-phase 200 V connection
3-phase
200 to 230 V AC
Note 1.
Make sure to connect between P3 and P4. When using the power factor
improving DC reactor, remove the short circuit bar between P3 and P4
before connection.
2.
When using the regenerative option, make sure to mount the
regenerative option between P+ and C. Ensure the connection
destinations are correct. The servo amplifier may malfunction if the
connection destinations are incorrect.
3.
Required only when the internal power supply (24 V DC) for the I/F is used in the existing MR-J2S-_A servo amplifier.
Not included with the renewal tool. Note that a separate
24 V DC power supply (current capacity: 80 mA or more) is required when replacing.
When connecting the 24 V DC power supply, use the "24 V DC power supply connection cable (model: SC-J2SJ4CTPWC5M)"
included in the package.
(Electric wire colors: Red (+ side); white (- side))
4.
When connecting a power regenerative converter (FR-RC-_K) and a brake unit (FR-BU2-_K), connect between P+ and N-. Make sure
to remove the built-in regenerative resistor or the regenerative option.
5.
Unnecessary if electromagnetic brakes are not installed.
6.
Required for the HG-JR22K1M motor only. There is no cooling fan for the HG-JR11K1M or HG-JR15K1M motor. Because the existing
wiring becomes unnecessary, insulate as needed.
7.
There is no cooling fan for the HG-JR11K1M or HG-JR15K1M motor. Because the existing wiring will become unnecessary, terminate
the cables.
8.
After replacing with the HG-JR22K1M, HG-JR30K1M. HG-JR37K1M, HG-JR45K1M or HG-JR55K1M motor, a new encoder cable
is required to be laid. Contact
* When using an existing encoder cable, an alarm No. AL46.3 (thermistor disconnected error) occurs.
