Additional functions
13.6 Electronic gear (EG)
Parameters
Variant 1:
FA
Block change mode
LA1, ... LA5
Z1, ... Z5
N1, ... N5
Only the leading axes previously specified with the EGDEF command may be programmed in
the activation line. At least one leading axis must be programmed.
Variant 2:
FA
Block change mode
[, LAi, SynPosLAi, Zi, Ni]
LA1, ... LA5
SynPosLAi
Z1, ... Z5
N1, ... N5
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 as
when the grouping is switched on, the following axis traverses to its defined synchronized
position.
Variant 3:
The parameters are the same as for variant 2 as regards:
Approach mode
13-26
Following axis
The following modes can be used:
"NOC" block change takes place immediately
"FINE" block change is performed for "synchronism
fine"
"COARSE" block change is performed for "synchronism
coarse"
"IPOSTOP" block change is performed for setpoint-
based synchronism
Leading axes
Counter for coupling factor i
Denominator for coupling factor i
Coupling factor i = Counter i / Denominator i
Following axis
The following modes can be used:
"NOC" block change takes place immediately
"FINE" block change is performed for "synchronism
fine"
"COARSE" block change is performed for "synchronism
coarse"
"IPOSTOP" block change is performed for setpoint-
based synchronism
(do not write the square brackets)
min. 1, max. 5 sequences of:
Leading axes
Synchronized position for i-th leading axis
Counter for coupling factor i
Denominator for coupling factor i
Coupling factor i = Counter i / Denominator i
synchronous
. If the electronic gear is not in the synchronized state
The following modes can be used:
"NTGT": Approach next tooth gap time-optimized
"NTGP" : Approach next tooth gap path-optimized
"ACN": Traverse rotary axis in negative direction
absolute
"ACP": Traverse rotary axis in positive direction
absolute
"DCT" Time-optimized with respect to programmed
synchronized position
"DCP" Path-optimized with respect to programmed
synchronized position
