4. DESCRIPTION OF PARAMETERS
B–63380EN/02
150
NOTE
1 These parameters are enabled when the VGR parameter
(bit 1 of parameter No.5200) is set to 1.
When a position coder is attached to the spindle, set the
same value for all of parameters No.5231 through No.5234.
When a spindle motor with a built–in position coder is used,
a position coder with a resolution of 2048 pulses/rev may be
used. In such a case, set the actual number of teeth,
multiplied by 2 (for conversion to 4096 pulses/rev).
2 When the DMR function of the position coder signal is used
with a serial spindle, set the VGR parameter (bit 1 of
parameter No.5200) to 0, and set these parameters to 0.
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] 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
For the F 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 same value
for parameter No.5242 and parameter No.5243. Otherwise,
P/S alarm No.200 will be issued.
