Note. The feedback position is outputted based on the position data passed between servo system controller and servo amplifier. [Pr.
PC13] and [Pr. PC14] can set up the standard position of feedback position that is outputted to analog monitor in order to adjust
the output range of feedback position. The setting range is between -9999 pulses and 9999 pulses.
Standard position of feedback position = [Pr. PC14] setting value × 10000 + [Pr. PC13] setting value
Parameter Description Setting range
PC13

feedback position
-9999 to 9999 [pulse]
PC14
Set the upper-order four digits of the standard position of
feedback position
-9999 to 9999 [10000 pulses]
