17. APPLICATION OF FUNCTIONS
(b) Operation when using a servo amplifier after change of specifications
For the controllers in which "Not required" is described to controller reset in table 17.3, the mode will
be switched to "J3 compatibility mode" for all axes at the first connection. It takes about 10 s for
completing the connection not depending on the number of axes.
For the controllers in which "Reset required" is described in table 17.3, the operation at the first
connection is shown in table 17.4. The servo amplifier's mode will be "J3 compatibility mode" and the
LED displays will be "rST" for all axes at the first connection to the controller as shown in table 17.4.
At the status, resetting controller once will change the display to "b##" (## means axis No.) for all
axes and all axes will be ready to connect.
(One controller reset enables to all-axis connection.)
(c) Using servo amplifiers before and after change of specifications simultaneously
When using servo amplifiers before change of specifications and after change of specifications
simultaneously, controller reset is necessary for number of connecting axes of servo amplifiers.
