Note. The feedback position is output 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 output 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
Sets the lower-order four digits of the standard position of
feedback position
-9999 to 9999 [pulse]
PC14
Sets the higher-order four digits of the standard position of
feedback position
-9999 to 9999 [10000 pulses]

Encoder pulse unit.
Available in position control mode
For 400 V class servo amplifier, the bus voltage becomes +8 V/800 V.
This cannot be used in the torque control mode.
This can be used with MR Configurator2 with software version 1.02C or later.
This cannot be used in the speed control mode.
Output in the load-side encoder unit for the fully closed loop control. Output in the servo motor encoder unit for the semi closed
loop control.
