Operation cannot be performed at the set frequency ... Why?
Did you carry out step 4 within 5 seconds after step 3? (Did you press the
SET
key within 5 seconds after turning the dial?)
Setting of higher than 60Hz cannot be made ... Why?
Check to see if the Pr. 1 "maximum frequency" setting is 60Hz.
The frequency does not change by turning the dial ... Why?
Check to see if the operation mode selected is the external operation
mode.
Remarks
Pressing the setting dial shows the set frequency.
•
The setting dial can also be used like a potentiometer to perform operation.
Set Pr. 30 "extended function display selection" to "1" (extended function
parameter valid) and Pr. 53 "frequency setting operation selection" to "1"
(setting dial potentiometer mode). Press the
RUN
key, turn the dial, and set
the frequency. After turning the setting dial, the frequency setting is changed
without pressing the
SET
key.
(For an operation example, refer to the instruction manual (detailed).)
