Name
The corner roundness amount ∆ c (mm) in respect to
Theor Cor
the angle (outer angle) θ (°) corner is displayed as
dull amt
the value obtained by totaling the error ∆ ca (mm) in
soft acceleration/deceleration 2 and the error ∆ cs
(mm) in the servo system.
∆ c = ∆ ca + ∆ cs
This data is calculated using the following
parameters.
330039 Corner slow angle (°)
120082 Prec soft time const 2 (ms)
160003 Position loop gain 1st axis (1/s)
130021 Feed forward gain 1st axis (%)

Theoretical roundness amount at corner
Corner dclr The value calculated with the following data is
speed displayed as the corner deceleration speed Fc
(mm/min) for the angle (outer angle) θ (°) corner.
This data is calculated using the following
parameters.
330039 Corner slow angle (°)
120037 Acc/dclr std feed (mm/min)
120038 Acc/dclr std time (ms)
330038 Precision coefficien (%)
Theor 90deg The corner droop amount for a 90° angle (outer
dull amt angle) is displayed.
θ is calculated as 90.
90deg Cor The corner deceleration speed for a 90° angle (outer
dec speed angle) is displayed.
θ is calculated as 90.
Prec coef This selects whether a precision coefficient or
(curve) vald precision coefficient for curves is used as the
compensation coefficient to further reduce the radius
reduction amount of a curve (arc, spline, NURBS
curve) during the high-accuracy control mode.
When "0" is set, the precision coefficient is applied,
and when "1" is set, the precision coefficient for
curves is applied.
Prec coef This sets the compensation coefficient to further
(curve) reduce the radius reduction amount of a curve (arc,
spline, NURBS curve) during the high-accuracy
control mode.
