15. MR-E- AG SERVO AMPLIFIER COMPATIBLE WITH ANALOG INPUT
15.5.2 Status display
(1) Status display list
The following table lists the servo statuses that may be shown:
Name Symbol Unit Description
Display
range
Cumulative feedback
pulses C pulse Feedback pulses from the servo motor encoder are counted and
displayed. The value in excess of 99999 is counted, bus since the
servo amplifier display is five digits, it shows the lower five digits of
the actual value. Press the "SET" button to reset the display value to
zero.
Reverse rotation is indicated by the lit decimal points in the upper
four digits. 99999
to
99999
Servo motor speed r r/min The servo motor speed is displayed.
The value rounded off is displayed in 0.1r/min. 5400

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.
The value is incremented in the CCW direction of rotation. 0
to

Within one-revolution
position high Cy2 100
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. 0
to
1310
