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
1) electronic gear setting = 1
2) electronic gear setting < 1
3) electronic gear setting > 1
