3. DISPLAY AND OPERATION SECTIONS
3 - 5
(2) Status display list
The following table lists the servo statuses that may be shown.
Status display Symbol Unit Description
Control
mode
(Note 1)
CP CL
Cumulative feedback
pulses
C pulse
Feedback pulses from the servo motor encoder are counted and
displayed.
The values in excess of ±99999 can be counted. However, the
counter shows only the lower five digits of the actual value since
the servo amplifier display is five digits.
Press the "SET" button to reset the display value to "0".
The decimal points in the upper four digits are lit for negative
value.
Servo motor speed r r/min
The servo motor speed is displayed.
It is displayed rounding off 0.1 r/min unit.
Droop pulses E pulse
The number of droop pulses in the deviation counter are
displayed.
The decimal points in the upper four digits are lit for reverse
rotation pulses.
The values in excess of ±99999 can be counted. However, the
counter shows only the lower five digits of the actual value since
the servo amplifier display is five digits.
The number of pulses displayed is in the encoder pulse unit.
Cumulative command
pulses
P pulse Not used with the positioning mode. "0" is always displayed.
Command pulse frequency n kpulse/s Not used with the positioning mode. "0" is always displayed.
Analog speed command
voltage
Analog speed limit voltage
F V
Not used with the positioning mode. An applied voltage to the
CN1 connector is displayed.
Analog torque command
voltage
U V
Not used with the positioning mode. An applied voltage to the
CN1 connector is displayed.
Analog torque limit voltage Voltage of TLA (Analog torque limit) is displayed.
Regenerative load ratio L %
The ratio of regenerative power to permissible regenerative
power is displayed in %.
Effective load ratio J %
The continuous effective load current is displayed.
The effective value in the past 15 s is displayed, with the rated
current being 100 %.
Peak load ratio b %
The maximum torque generated is displayed.
The highest value in the past 15 s is displayed, with the rated
torque being 100 %.
Instantaneous torque T %
The instantaneous torque is displayed.
The torque generated is displayed in real time, with the rated
torque being 100%.
Within one-revolution
position (1 pulse unit)
Cy1 pulse
Position within one revolution is displayed in encoder pulses.
The values in excess of ±99999 can be counted. However, the
counter shows only the lower five digits of the actual value since
the servo amplifier display is five digits.
When the servo motor rotates in the CCW direction, the value is
added.
Within one-revolution
position (1000 pulse unit)
Cy2 1000 pulses
The within one-revolution position is displayed in 1000 pulse
increments of the encoder.
When the servo motor rotates in the CCW direction, the value is
added.
ABS counter LS rev Travel distance from power on is displayed by counter value.
Load to motor inertia ratio dC Multiplier
The estimated ratio of the load inertia moment to the servo motor
shaft inertia moment is displayed.
Bus voltage Pn V
The voltage of main circuit converter (between P+ and N-) is
displayed.
Encoder inside
temperature
ETh °C
Inside temperature of encoder detected by the encoder is
displayed.
Settling time ST ms
Settling time is displayed. When it exceeds 1000 ms, "1000" will
be displayed.
Oscillation detection
frequency
oF Hz Frequency at the time of oscillation detection is displayed.
Number of tough drive
operations
Td times The number of tough drive functions activated is displayed.
