Parameter Frequency setting by analog input (terminal 2, 4)
FR-E700 SC EC/ENE 6 - 189
3. Method to adjust only the frequency without adjustment of a gain voltage (current).
(The gain frequency is changed from 50 Hz to 40 Hz.)
I001820E
Fig. 6-98: Adjusting only the frequency without adjustment of a voltage (current)
NOTES Changing C4 (Pr. 903) or C7 (Pr. 905) (gain adjustment) value will not change the Pr. 20 value.
For the operation procedure using the parameter unit (FR-PU04/FR-PU07), refer to the FR-PU04/
FR-PU07 instruction manual.
When setting the value to 120 Hz or more, it is necessary to set Pr. 18 "High speed maximum fre-
quency" to 120 Hz or more. (Refer to page 6-52.)
Make the bias frequency setting using calibration parameter C2 (Pr. 902) or C5 (Pr. 904). (Refer to
page 6-184.)
E
CAUTION:
Take care when setting any value other than "0" as the bias speed at 0 V (0/4 mA). Even if a
frequency command is not given, merely turning on the start signal will start the motor at the
preset frequency.
햲
Turn the digital dial until P.125 (Pr. 125) or
P.126 (Pr. 126) appears
햳
Press the SET key to show the currently
set value (50.00 Hz).
햴
Turn the digital dial to change it
to the setting value of "40.00" (40.00 Hz).
햵
Press the SET key to set.
햶
Press the MODE key twice to choose
monitor/frequency monitor.
햷
Apply the maximum signal value to the
terminals 2-5 (4-5) and turn the start
signal (STF or STR) on. The inverter will
accelerate the motor to 40 Hz.
