M3: Coupled axes
14.4 Electronic gear (EG)
with:
"FA": Following axis
Block change mode:
"NOC": Block change takes place immediately
"FINE": Block change is performed in "Fine synchronism"
"COARSE": Block change is performed in "Coarse synchronism"
"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.
"ACN": AbsoluteCoordinateNegative, Absolute measurement specification, rotary axis
traverses in negative rotation direction
"ACP": AbsoluteCoordinatePositive, Absolute measurement specification, rotary axis
traverses in positive rotation direction
"DCT": DirectCoordinateTime-optimized, Absolute measurement specification, rotary axis
traverses time-optimized to programmed synchronized position
"DCP": DirectCoordinatePath-optimized, Absolute measurement specification, rotary axis
traverses path-optimized to programmed synchronized position
LA : Axis name of the leading axis i
i
SynPosLAi: Synchronized position of leading axis i
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.
The function is active only for modulo following axes that are coupled to modulo leading axes.
Tooth gap
The tooth gap is defined as 360 degrees * Zi / Ni
Example:
EGONSYNE(A, "FINE", FASysPos, "Traversing mode", B, LASynPos, 2, 10)
Tooth gap: 360*2/10 = 72 (degrees)
