Zi: Counter for coupling factor of leading axis i
Ni: Denominator for coupling factor of leading axis i
Note
The parameters indexed with i must be programmed for at least one leading axis, but for no
more than five.
Only leading axes previously specified with the EGDEF command may be programmed in
the activation line.
Through the programmed "Synchronized positions" for the following axis (SynPosFA) and for
the leading axes (SynPosLA), positions are defined for which the axis grouping is interpreted
synchronous
as
switched on, the following axis traverses to its defined synchronized position.
The position specification of the synchronized positions is specified in the configured basic
system independently of the programmable dimensions (G70/G71).
If the axis grouping includes modulo axes, their position values are reduced in the modulo,
This way they approach the fastest possible synchronized position. (So-called
synchronization
If the following interface signal has not been set for the following axis, the axis will not travel
to the synchronization position.
DB31, ... DBX26.4 (Enable following axis override)
Instead the program is stopped at the EGONSYN block and the self-clearing alarm 16771 is
issued until the above mentioned signal is set.
2. EGONSYNE
EGONSYNE(FA, block change mode, SynPosFA, Approach mode, LA
N_LA
with:
"FA": Following axis
Block change mode:
"NOC": Block change takes place immediately
"FINE": Block change is performed in "Fine synchronization"
"COARSE": Block change is performed in "Coarse synchronization"
"IPOSTOP": Block change is performed for setpoint-based synchronism
SynPosFA: Synchronized position of the following axis
Approach mode:
"NTGT": NextToothGapTime-optimized, the next tooth gap is approached time-optimized
(preset is used if no setting is applied).
"NTGP": The next tooth gap is approached time-optimized.
Special functions: Axis Couplings and ESR (M3)
