[Data type] Word
[Valid data range] 1 to 32767
When an arbitrary gear ratio is used in rigid tapping, each of these
parameters sets the number of teeth of each position coder gear.
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.
3 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.5231 and No.5232 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.5235 and No.5236 are applied to the second
spindle.
