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
Set the lower-order four digits of the standard position of
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]
(d) Maximum current command (maximum torque) for analog monitor 10 V ±4 V
Values of the maximum current command (maximum torque) when the analog monitor is 10 V ±4 V
are listed.
The current command (torque) outputs the maximum current command (maximum torque) at 10 V
±4 V. The maximum current command (maximum torque) may not match the rated current/maximum
current ratio since it is created from the torque current in the servo amplifier.
