Frequency setting by analog input (terminal 2, 4)
(c) Adjusting only the frequency without adjusting the gain voltage (current).
(When changing the gain frequency from 60Hz to 50Hz)
Operation
1.
Turn
until
(Pr. 126) appears
2.
Press
to show the present set value.
(60.00Hz)
3.
Turn
to change the set value to
"
". (50.00Hz)
4.
Press
to set.
5.
Mode/monitor check
Press
twice to choose the monitor/
frequency monitor.
6.
Apply a voltage across the inverter terminals 2
and 5 (across 4 and 5) and turn ON the start
command (STF, STR).
Operation starts at 50Hz.
REMARKS
 Changing C4 (Pr. 903) or C7 (Pr. 905) (gain adjustment) value will not change the Pr. 20 Acceleration/deceleration reference
frequency setting.
 For operation from the parameter unit (FR-PU04/FR-PU07), refer to the Instruction Manual of the FR-PU04/FR-PU07.
 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 101)
 Make the bias frequency setting using the calibration parameter C2 (Pr. 902) or C5 (Pr. 904). (Refer to page 189)
 Refer to page 284 to use the FR-E500 series operation panel (PA02).
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.
