17.1.8 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 17.1, 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 17.1, the operation at the first
connection is shown in table 17.2. The LED displays will be "Ab." for all axes at the first connection
to the controller as shown in table 17.2. 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.
