Change Of Specifications Of "J3 Compatibility Mode" Switching Process - Mitsubishi Electric MELSERVO-J4 Series Transition Handbook

Part 7: Common Reference Material

6.1.9 Change of specifications of "J3 compatibility mode" switching process

(1) Detailed explanation of "J3 compatibility mode" switching
(a) Operation when using a servo amplifier before change of specifications
For the controllers in which "Not required" is described to controller reset in table 7.3, the mode will
be switched to "J3 compatibility mode" for all axes at the first connection. However, it takes about 10
s per axis for completing the connection.
For the controllers in which "Reset required" is described in table 7.3, the operation at the first
connection is shown in table 7.4. The LED displays will be "Ab." for all axes at the first connection to
the controller as shown in table 7.4. After that, resetting controller will change the 1-axis to "b01".
The 2-axis and later will not change from "Ab.". After that, one axis will be connected per two times
of controller reset.
