Adjustment Functions
Before starting the fit gain function, make the following settings using the fit gain window on the front
panel, parameter setting mode, the Parameter Unit, or CX-Drive.
Operating Procedure
1. Set the front panel display to the execution display of the fit gain window.
(Refer to the
Front Panel Display Example
on page 7-9 for information on using the front panel.)
2. With the dot at the far right flashing, decrease the rigidity to 0, and press the
Decrement key on the front panel for 3 s min. to start the fit gain function.
3. Input a position command that satisfies the operating pattern conditions given in
Precautions for Correct Use
under
If the fit gain is completed normally,
will be displayed, and
will be displayed
if it is completed with an error. (The
display can be cleared using the keys.)
• Time is required for the change to be made for fit gain operation. It may take approximately 2 or
3 min. depending on the equipment configuration, which may require up to approximately 50
reciprocating operations. Normally, the fit gain will be completed when the optimal realtime rigidity
number is found.
•
will be displayed in the following cases.
•
The INP signal becomes unstable, or a realtime rigidity number without small vibration is not
found.
•
The keys on the front panel are used while fit gain is operating or the applicable conditions are
not satisfied.
