: Block change behavior
The block change is:
"NOC"
"FINE"
"COARSE"
"IPOSTOP"
The block change behavior is effective modally.
: Coupling type: Coupling between FS and LS
"DV"
"AV"
"VV"
The coupling type is modal.
: Angle offset between leading and following spindles
Range of values:
: Switch-off positions of the following and leading spindles
"The block change is enabled once POS
Range of values:
Immediately
On reaching "Synchronism fine"
On reaching "Synchronism coarse"
On reaching IPOSTOP; in other words, after
setpoint-based synchronism (default)
Setpoint linkage (default)
Actual value coupling
Speed coupling
0°... 359.999°
0°... 359.999°
Comment
Leading spindle = master spindle = spindle 1
Following spindle = spindle 2
Leading spindle rotates at 3000 rpm,
following spindle at 500 rpm.
Definition of the coupling (can also be
configured).
Bring leading spindle into closed-loop position
control (setpoint coupling).
Bring following spindle into closed-loop position
control.
On-the-fly coupling to offset position =
45 degrees.
Positioning speed = 100 degrees/min
Traverse with 90 degree overlay in negative
direction.
Wait for "fine" synchronism.
