16 Machine Parameters
(PR) #3031 smcp_no
Set the interface channel No. of CNC control unit to which the spindle is connected and the axis No. within
each channel.
Set this parameter in 4-digit (hexadecimal) format.
HEX- 4
0
HEX-4 : Drive unit interface channel No.
HEX-3 : Not used. Set to "0".
HEX-2, 1 : Axis No.
For an analog spindle, set to "0000".
---Setting range---
0000, 1001 to 1010, 2001 to 2010
#3032
Not used. Set to "0".
(PR) #3035 spunit
Select the data unit for communication with the spindle drive unit.
This selection is applied to the data communicated between the NC and spindle drive unit as well as the spin-
dle movement data. Although the standard setting is B (0.001deg), set the same value as "#1004 ctrl_unit"
when using Spindle/C axis control.
B: 0.001deg (1μm)
C: 0.0001deg (0.1μm)
D: 0.00001deg (10nm)
E: 0.000001deg (1nm)
#3037 taps21
Set the speed which switches from 2nd step to 3rd step in synchronous tapping multi-step acceleration/de-
celeration control when gear 00 is selected.
The inclination of linear acceleration/deceleration control for 2nd step is determined by the ratio of
"taps21"(#3037) to "tapt21"(#3041).
When the inclination is not set for 3rd step or it is higher than that of 2nd step, the acceleration/deceleration
control is executed with the same inclination as the 2nd step for the rotation speed of "taps21" or higher.
---Setting range---
0 to 99999 (r/min)
#3038 taps22
Set the speed which switches from 2nd step to 3rd step in synchronous tapping multi-step acceleration/de-
celeration control when gear 01 is selected.
The inclination of linear acceleration/deceleration control for 2nd step is determined by the ratio of
"taps22"(#3038) to "tapt22"(#3042).
When the inclination is not set for 3rd step or it is higher than that of 2nd step, the acceleration/deceleration
control is executed with the same inclination as the 2nd step for the rotation speed of "taps22" or higher.
---Setting range---
0 to 99999 (r/min)
