Setting method of reference frequency
[ 1 ] Frequency setting by keypad (F01 = 0 (Factory default state), 8)
(1) Set the data of function code F01 to “0” or “8”. When keypad is at program mode or alarm mode, it is not
possible to perform frequency setting with / keys. In order to enable frequency setting with / keys,
shift to the operation mode.
(2) When / key is pressed, reference frequency is displayed and the least significant digit of the reference
frequency flashes.
(3) By pressing the / key again, it is possible to change the reference frequency. To save the set frequency,
press key. (E64=0: Factory default state). When the frequency is saved, it is possible to operate with the
saved frequency next time the power is turned on.
• Automatic saving method (Function code E64 = 0) is available other than the above method as a data
saving method of frequency setting.
While the data of function code F01 is set to “0” or “8”
, when frequency setting method other than
frequency setting 1 (frequency setting 2, communication, multistep frequency
frequency setting, it is not possible to change the reference setting with / keys even if keypad
at operation mode. In this case, pressing / keys
displays the currently selected reference
When frequency setting is performed with / key
s, the least significant digit displayed flashes
and the data is changed from the least significant digit and the changing digit gradually shifts to the
In order to perform setting such as reference frequency, press / once and when the lea
significant digit flashes, push down the
key, and then, the flashing digit will move. Therefore, it is
possible to change the large numerical number easily. This operation is called cursor movement.
When the data of function code F01 is set to “8”
, balanceless bumpless function becomes enabled.
When switching to frequency setting with keypad from frequency setting method other than keypad,
the switched initial value of frequency setting with keypad takes the value of
the frequency setting
before it is switched. By using this function, even if frequency setting is switched, it is possible to
perform operation without shock.
