parameter
Couple on:
Activate ELG group/synchronous spindle pair. If
no activation positions are specified, the couple is
activated as quickly as possible (ramp). If an
activation position is specified for the following
axis and spindle, this refers absolutely or
incrementally to the master axis or spindle.
Parameters 4 and 5 only have to be programmed
if the 3rd parameter is specified.
REAL: Couple OFF:
Deactivation Deactivate ELG group/synchronous spindle pair.
position of The couple parameters are retained. If positions
master axis are specified, the couple is only canceled when all
(absolute) the specified positions have been overtraveled.
The following spindle continues to revolve at the
last speed programmed before deactivation of the
couple.
STRING[8]: Wait for couple condition:
Block Wait until couple block change criterion for the
change axes/spindles is fulfilled.
criterion Up to two axes/spindles can be programmed.
Block change criterion:
"NOC": No block change control, block change is
enabled immediately,
"FINE": Block change on "synchronism fine",
"COARSE": Block change on synchronism coarse
and
"IPOSTOP": Block change in setpoint-dependent
termination of overlaid movement.
If the block change behavior is not specified, the
set behavior is applicable and there is no change.
Advance container axis.
