Press the Key for forward
operation or the Key for
reverse operation.
The motor will repeatedly perform
round-trip operation within 1/4th of
a rotation and the SERVOPACK will
measure the resonance frequency.
During detection, Measure will flash
on the display.
If detection processing is com-
pleted normally, the detected
results and notch filter value will be
displayed. Measure will change to
Result.
Note: 1. If a notch filter has been set and
is being used, an asterisks will
be displayed on the second
line.
If the first notch filter has
already been set, the second
notch filter value will be dis-
played. If the first and second
notch filters have already been
set, only the result of frequency
detection will be displayed.
2. If you press the Key
during motor operation, the
motor will stop and the fre-
quency will not be detected.
3. If the frequency could not be
successfully detected, No
Measure will be displayed.
4. If you press the Key after
the frequency is detected,
power is no longer supplied to
the motor (base block).
