Within one-revolution
position low
Cy1 pulse Position within one revolution is displayed in encoder pulses.
The value returns to 0 when it exceeds the maximum number of pulses.
However, the counter shows only the lower five digits of the actual value
since the servo amplifier display is five digits.
The value is incremented in the CCW direction of rotation.

pulse
The within one-revolution position is displayed in 100 pulse increments of
the encoder.
The value returns to 0 when it exceeds the maximum number of pulses.
The value is incremented in the CCW direction of rotation.

6.3.4 Changing the status display screen
The status display item of the servo amplifier display shown at power-on can be changed by changing the
parameter No.PC36 settings.
The item displayed in the initial status changes with the control mode as follows.
