VA
Description
Velocity set
Syntax
xx VA nn
Remarks
This command is used to set the velocity value for an axis. The velocity setting specified will
not have any effect on a move that is already in progress. If this command is issued when an
axis’ motion is in progress, the controller will accept the new value but it will use it for
subsequent moves only. The maximum velocity for a ‘Standard’ Picomotor is 2000 steps/sec,
while the same for a ‘Tiny’ Picomotor is 1750 steps/sec.
Argument Value Description
xx 1 to 2 Axis number
nn 1 to 2000 Velocity (steps/sec). Default = 2000 steps/sec
Example
