Ctrl Command stepper_rel_no
Function triggers set-position movements to the specified relative set positions via the desired
stepper motor output.
Call
stepper_rel_no( No, dPos, WaitTime )
Parameters
No
dPos
WaitTime
Comments • The desired set positions should be specified relative to the current internal set-position
values (the internal set-position values will correspondingly get newly set) and a set-
position movement will only be performed at the stepper motor output specified by No.
Otherwise the command is identical to
