9. SPINDLE SPEED FUNCTION
390
5241
Maximum spindle speed in rigid tapping (first–stage gear)
5242
Maximum spindle speed in rigid tapping (second–stage gear)
5243
Maximum spindle speed in rigid tapping (third–stage gear)
[Data type] Two–word
[Unit of data] rpm
[Valid data range] Spindle and position coder gear ratio
1 : 1 0 to 7400
1 : 2 0 to 9999
1 : 4 0 to 9999
1 : 8 0 to 9999
These parameters set the maximum spindle speed for every gear in rigid
tapping.
NOTE
In a system having one–stage gear, set the same value as
parameter No. 5241 to parameter No. 5243. In a system
having two–stage gear, set the same value as parameter
No. 5242 to parameter No. 5243. If it is not set as such, P/S
alarm no. 200 will be informed.
5261
Linear acceleration/deceleration time constant for the spindle and tapping axis
(first–stage gear)
5262
Linear acceleration/deceleration time constant for the spindle and tapping axis
(second–stage gear)
5263
Linear acceleration/deceleration time constant for the spindle and tapping axis
(third–stage gear)
[Data type] Word
[Unit of data] ms
[Valid data range] 0 to 4000
These parameters set the spindle and tapping axis’s time constant for
every gear during linear acceleration/deceleration in rigid tapping.
Set the time required until a spindle speed reaches the maximum spindle
speed (parameter Nos. 5241 and greater). The actual time constant is a
proportional value between the maximum spindle speed and the specified
spindle speed.
