Positioning the following spindle: Options
When the synchronized spindle coupling is active,
following spindles can also be positioned within the
±180° range independently of the motion initiated by
the master spindle.
Positioning SPOS
The following spindle can be interpolated with
SPOS=...
Please refer to Programming Guide "Fundamentals"
for more information about SPOS.
Example:
N30 SPOS[2]=IC(-90)
FA, ACC, OVRA :
Speed, acceleration
The position speeds and acceleration rates for
following spindles can be programmed with
FA[SPI(Sn)] or FA[Sn], ACC[SPI(Sn)] or ACC[Sn]
and OVRA[SPI(n)] or OVRA[Sn] (see Programming
Guide, Fundamentals). "n" stands for spindle
number 1...n.
Programmable block change WAITC
WAITC can be used to define the block change
behavior with various synchronism conditions
(coarse, fine, IPOSTOP) for continuation of the
program, e.g. after changes to coupling parameters
or positioning operations.
WAITC causes a delay in the insertion of new blocks
until the appropriate synchronism condition is
fulfilled, thereby allowing the synchronized state to
be processed faster.
If no synchronism conditions are specified, then the
block change behavior programmed/configured for
the relevant coupling applies.
