EXECUTION 
display
(1) Bring the front panel display to EXECUTION
display of the Fit-Gain screen.
(For operation of the front panel, refer to P.72
of Preparation.)
(2) Start up the Fit-Gain function by pressing
for approx. 3sec after lowering the stiffness 
to 0 while the dot “ ” on the right lower cor-
ner flashes.
(3) Enter the position command which satisfies
the action pattern condition of P.228,
"Applicable Range".

<Caution 1>
The Fit-Gain movement requires max. 50 re-
ciprocating movements. The Fit-gain function
finishes when the optimum real-time stiffness
No. is found in normal case.

function finishes normally, and will be
displayed when this finishes with error.
