4. DESCRIPTION OF PARAMETERS
B–63610EN/01
236
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)
5244
Maximum spindle speed in rigid tapping (fourth–stage gear)
5245
Maximum spindle speed in rigid tapping using the second spindle (first–stage gear)
5246
Maximum spindle speed in rigid tapping using the second spindle (second–stage gear)
[Data type] 2–word
[Unit of data] min
–1
[Valid data range] Spindle position coder gear ratio
1:1 0 to 7400
1:2 0 to 9999
1:4 0 to 9999
1:8 0 to 9999
Each of these parameters is used to set a maximum spindle speed for each
gear in rigid tapping.
NOTE
1 For the M series, set the same value for both parameter
No.5241 and parameter No.5243 for a one–stage gear
system. For a two–stage gear system, set the value of
parameter No.5241 or No.5242, whichever is greater, in
parameter No.5243. Otherwise, P/S alarm No.200 will be
issued.
2 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.5241 and
No.5242 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.5245 and
No.5246 are applied to the second spindle.
