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