Description
Feedback pulses from the servo motor encoder are counted and
displayed. The value in excess of k9999 is counted, bus since the
servo amplifier display is four digits, it shows the lower four digits of
the actual value. Press the
"SET'
button
to
reset the display value to
zero.
The servo motor speed is displayed. When the servo motor is rotating
in the reverse direction, the decimal points in the upper 3 digits are
lit. The value rounded
off
is displayed in XO.lr/min.
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 3 digits are lit.
Since the servo amplifier display is four digits, it shows the lower
four digits
of
the actual value.
The position command input pulses are counted and displayed.
-4s
the value displayed is not multiplied by the electronic gear, it may
not match the indication of the cumulative feedback pulses. The
value in excess of +9999 is counted, but since the servo amplifier
display is four digits, it shows the lower four 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
3
digits are lit.
The frequency of the position command input pulses is displayed.
The value displayed is not multiplied by the electronic gear. When
the servo motor is rotating in the reverse direction, the decimal
points in the upper
3
digits are lit.

The ratio of regenerative power
to
permissible regenerative power is
displayed in
%.
The continuous effective load torque is &splayed.
The effective value is displayed relative to the rated torque of 100%.
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%.
Position within one revolution is displayed in encoder pulses.
The value returns to
0
when it exceeds the maximum number
of
pulses.
The value of the multi-revolution counter is displayed.
Since the servo amplifier display is four digits, it shows the lower
four digits of the actual value.
The estimated ratio
of
the load inertia moment to the servo motor
shaft inertia moment
1s
displayed.
