Change the frequency (40Hz) of the maximum value of potentiometer (at 20mA)
쑶
Example
쑴
The frequency of the maximum analog current of the potentiometer (at 20mA) has to be
changed from the initial setting of 50Hz to 40Hz. Set 40Hz in Pr. 126.

Change the frequency of the maximum analog value
NOTES
Set the frequency at 4mA using calibration parameter C5.
As other adjustment methods of frequency setting current gain, there are methods to adjust
with a current flowing in the terminals 4-5 and adjust at any point without a current flowing.
(Refer to section 6.15.3 for the setting method of calibration parameter C7.)
When performing a high speed operation at 120Hz or more, setting of Pr. 18 "High speed
maximum frequency" is necessary. (Refer to section 6.3.1.)
Turn the digital dial until P.126 (Pr. 126) appears.
Press the SET key to show the currently set value.
The initial value "50.00" (50.00Hz) appears.
Turn the digital dial to change the set value to
"40.00" (40.00Hz).
Press the SET key to set.
Press the MODE key twice to choose monitor/
frequency monitor.
Turn the start switch STF or STR on to allow 20mA
current to flow.
(Refer to Fig. 5-29, step
