Appendix 1 Explanation of Parameters
【#3028】 sprcmm Tap cycle spindle forward run/reverse run M command (L system only)
Set the M codes for the spindle forward run/reverse run commands during asynchronous tapping.
High-order 3 digits: Set the M code for spindle forward run command.
Low-order 3 digits: Set the M code for spindle reverse run command.
When "0" is set, the M code for spindle forward run command is handled as "3" and the M code for
spindle reverse run command as "4".
---Setting range---
0 to 999999
【#3029】 tapsel
Not used. Set to "0".
【#3031(PR)】 smcp_no Drive unit I/F channel No. (spindle)
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-
HEX-4 : Drive unit interface channel No.
HEX-3 : Not used. Set to "0".
HEX-2, 1 : Axis No.
For a spindle to be connected to CNC via analog interface, set to "0000".
---Setting range---
1001 to 1010
- For MDS-DM2-SPV2/SPV3 Series
These drive units have no rotary switches for axis No. selection.
The spindle axis No. is fixed to 1st axis, so set "01" as the number of axes. (last 2 digits).
【#3035(PR)】 spunit Output unit
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 spindle movement data. Note, however, that this parameter is enabled only for the MDS-D
Series spindle drive unit.
Spindle/C axis depends on this parameter setting and the C axis output unit (servo) is ignored.
B: 1μm
C: 0.1μm
【#3037】 taps21 Synchronous tapping 2nd step rotation speed (Gear: 00)
Set the speed which switches from 2nd step to 3rd step in synchronous tapping multi-step
acceleration/deceleration 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.
