Symbol Unit
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.
r r/min The servo motor speed is displayed.
The value rounded off is displayed in
E pulse The number of droop pulses in the deviation counter is displayed.
When the servo motor is rotating in the reverse direction, the
decimal points in the upper four digits are lit.
Since the servo amplifier display is five digits, it shows the lower five
digits of the actual value.
The number of pulses displayed is not yet multiplied by the electronic
gear.
P pulse The position command input pulses are counted and displayed.
As the value displayed is not yet multiplied by the electronic gear
(CMX/CDV), it may not match the indication of the cumulative
feedback pulses.
The value in excess of
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. When the servo motor is rotating in the reverse direction, the
decimal points in the upper four digits are lit.
n kpps The frequency of the position command input pulses is displayed.
The value displayed is not multiplied by the electronic gear
(CMX/CDV).
F V (1) Torque control mode
Analog speed limit (VLA) voltage is displayed.
(2) Speed control mode
Analog speed command (VC) voltage is displayed.
U V (1) Position control mode, speed control mode
Analog torque limit (TLA) voltage is displayed.
(2) Torque control mode
Analog torque command (TLA) voltage is displayed.
L % The ratio of regenerative power to permissible regenerative power is
displayed in %.
J % The continuous effective load torque is displayed.
The effective value in the past 15 seconds is displayed relative to the
rated torque of 100%.
b % The maximum torque generated during acceleration/deceleration, etc.
The highest value in the past 15 seconds is displayed relative to the
rated torque of 100%.
T % Torque that occurred instantaneously is displayed.
The value of the torque that occurred is displayed in real time
relative to the rate torque of 100%.
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.
