tapping axis (first-stage gear)

[Data type] Word
[Unit of data] ms
[Valid data range] 0 to 4000
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
spindle
• 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
spindle, 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.
