Fig.8.2 Relationship Between Commanded Speed and Actual Speed
The relationship between the commanded speed (positioning speed set in the
servo program) and actual speed (actual positioning speed) is shown below for
different electronic gear settings.
• if electronic gear setting = 1, commanded speed = actual speed
• if electronic gear setting < 1, commanded speed < actual speed
• if electronic gear setting > 1, commanded speed > actual speed
