Enter the link factor for the main axis by specifying the denominator and the
numerator (8 decimal places + decimal point + leading sign). Activate the entry
by pressing the LINK_ON/LINK_SWITCH softkey. The entered link factor is
only accepted if a gearbox interpolation group has already been configured.
Input field for the synchronization position for flying synchronization (8
decimal places + decimal point + leading sign). An absolute value must be
entered. The reference system is always the machine coordinate system.
Activate the entry by pressing the FLYING SYNCHRON. softkey twice. The
machine position is only accepted if a gearbox interpolation group has been
configured. After the link has been activated by pressing the softkey, the value
disappears from the screen.
If + or - is entered, the machine position is only accepted if the position entered
has been crossed in the positive or negative direction. If no sign is entered, the
direction is irrelevant.
Enter here the number of the IKA data record used.
Enter here the control curve number of the IKA.
The entries for IKA and IKP are only relevant if a GI type curve has been
selected.
The current status of the gearbox link is entered here by the system. A toggle
key allows you to activate or deactivate the link for each main drive. Activate
