Deskew Parameters

Important: The master servo selected here must be assigned as any axis
that precedes the slave axis. The deskew slave axis must always be the
highest number axis in the process that precedes the spindle(s). For
example, if configuring a three-axis system with no spindle and the X axis
is driven by two servo motors, this configuration could be used:
Axis Number
(servo)
Axis Name
(name of servo)
Configuration
1 X Configured as Deskew Master Servo Name
2 Y Normal Servo Configuration
3 Z Normal Servo Configuration
4 U Configured as Deskew Slave Servo Name
The above configuration would result in servos 1 and 4 being part of a split
axis. The name used for the split axis is X. Both the X and U servos
would respond to any programmed or jog requests for the X axis. X and U
would not be available for independent positioning. Common axis
parameters AMPed for the U axis (such as acc/dec ramps, feedrates, etc.)
would be ignored and replaced with the values entered for the master axis
X (refer to the parameter Deskew Master Servo Name for a listing of
slave servo parameters that are ignored).
For a Dual Processing control, you can use this configuration:
Axis Number Axis Name Configuration
1 X Process 1 X
2 Z Process 1 Master
3 W Process 1 Slave
4 X Process 2 X
5 Z Process 2 Master
6 W Process 2 Slave
7 S1 Process 1 Spindle
8 S2 Process 2 Spindle
