C axis with
separate drive
The standard configuration features two spindles (workpiece spindle S1 and
tool spindle S2). The C axis with separate drive is realized via spindle 4 (S4).
Spindle S3 must be configured additionally to spindle S4. The parameters
already exist in the axis data (PS3_0, PS4_0 and PS4_C1). Spindle S3 is marked
as inactive in the axisMode parameter in the CfgAxis entity.
Make the following changes to active the C axis with separate drive via spindle
S4:
 Insert spindles S3 and S4 in the axisList and spindleIndices lists under
CfgAxes.
 Assign the separate spindle (S4) to the C axis (C1) in MP_relatedAxis
 In addition, assign the workpiece spindle (S1) to the C axis in
MP_relatedWpSpindle.
Note
Please note that, if the same position encoder is used for the main spindle
and the C axis, the operation of a separately driven C axis along with the
use of a CC 61xx is not possible until the beginning of 2012. Contact
HEIDENHAIN if you need this feature before the above mentioned date.
