CDM
[Data type] Bit
CDM Cs axes in this path are
0 : not hypothetical Cs axes.
1 : hypothetical Cs axes.
When this parameter is “1” and Cs axis is defined at the parameter No.1023,
hypothetical Cs axis is added if the real Cs axis is not connected. In this time,
composite control which exchange hypothetical Cs axis for real Cs axis is
enabled in multi-path control system.
Note1) If the parameter CDM=1, real Cs axes can not be connected in this path.
Note2) When hypothetical Cs axis is used, set the parameter No.1023=-1/-2/-3/-4 as if
hypothetical serial spindle is added. If real serial spindles are connected in the
path which hypothetical Cs axis is used, set the parameters as follows.

* The sum of real spindles and hypothetical Cs axes can not be over “4”.
Note3) Set the parameter ECS(No.3702#7)=0.
Set the feedrate and any other parameter even if the control axis is hypothetical
Cs axis. But setting of serial spindle parameters (No.4000-No.4539) is not
necessary.
Note4) When Cs axis composite control is used, set the parameter CZM(No.8161#1)=1.
(Synchronous control and composite control option is necessary.)
Note5) When this parameter has been set, the power must be turned off before
operation is continued.
