Each of these parameters is used to set a linear acceleration/deceleration time
constant for the spindle of each gear and the tapping axis in rigid tapping.
Set the period required to reach each maximum spindle speed (parameters
No.5241 through No.5248). The set time constant, multiplied by the ratio
of a specified S value to a maximum spindle speed, is actually used as a
time constant.
NOTE
When rigid tapping is performed using the second and third
spindles
• When the SPR parameter (bit 1 of parameter No.5204)
is set to 0, the settings of parameters No.5261 and
No.5262 are applied to the second and third spindles, as
well as to the first spindle.
• When the SPR parameter (bit 1 of parameter No.5204)
is set to 1, the settings of parameters No.5265 and
No.5266 are applied to the second spindle, while the
settings of parameters No.5267 and No.5268 are applied
to the third spindle.
