Frequency setting by analog input (terminal 1, 2, 4)
(c) Method to adjust only the frequency without adjustment of a gain voltage (current).
(When changing the gain frequency from 50Hz to 60Hz)
REMARKS
Changing
C4 (Pr. 903)
or
C7 (Pr. 905)
(gain adjustment) value will not change the
Pr. 20
value. The input of terminal 1 (frequency
setting auxiliary input) is added to the speed setting signal.
For the operating procedure using the parameter unit (FR-PU04/FR-PU07), refer to the FR-PU04/FR-PU07 instruction manual.
When setting the value to 120Hz or more, it is necessary to set
Pr. 18 High speed maximum frequency
to 120Hz or more.
(Refer to
page 76)
Make the bias frequency setting using
calibration parameter C2 (Pr. 902) or C5 (Pr. 904).
(Refer to page 163)
CAUTION
Be cautious when setting any value other than "0" as the bias frequency at 0V (0mA). Even if a speed command
is not given, merely turning on the start signal will start the motor at the preset frequency.
