HEIDENHAIN iTNC 530 HSCI - Master-Slave Position Deviation

July 2013 6.6 Gantry/synchronized axes 779
The function is effective during control both with following error and with
velocity feedforward.
Activating synchronized axes:
 Assign a slave axis to a master axis.
MP850.x Synchronized axes
Input: 0: Master axis
1: Slave axis to axis 1
2: Slave axis to axis 2
3: Slave axis to axis 3
4: Slave axis to axis 4
5: Slave axis to axis 5
6: Slave axis to axis 6
7: Slave axis to axis 7
8: Slave axis to axis 8
9: Slave axis to axis 9
Example Axis 4 is slave to axis 1:
 MP850.0 = 0
 MP850.1 = 0
 MP850.2 = 0
 MP850.3 = 1
 MP850.4 = 0
 MP850.5 = 0
 MP850.6 = 0
 MP850.7 = 0
 MP850.8 = 0
Master-slave
position deviation
The iTNC monitors the synchronism of the coupled axes. If the master and
slave axes deviate from each other by the difference of the following errors,
the iTNC displays the slave axis with the message EXCESSIVE SERVO LAG
IN <AXIS>. The LAG display shows the current difference in position.
 In MP855.x of the slave axis, enter the maximum permissible difference in
positions between the master and slave.
Machine parameter MP855.x (synchronization monitoring) is effective for all
slave axes of a synchronized drive (if a value > 0 has been entered), regardless
of whether it is a gantry or master-slave combination.
If an offset is caused in the axes through an emergency stop, they will be
synchronized after the emergency stop.
