Mitsubishi Electric F700 Instruction Manual page 140

(c) Method to adjust only the frequency without adjustment of a gain voltage (current).
(When changing the gain frequency from 50Hz to 60Hz)
Operation
1.
(Pr. 126) appears.
2.
Press to show the currently set value.
(50.00Hz)
3.
Turn to change the set value to
"60.00". (60.00Hz)
4.
Press to set.
5.
Mode/monitor check
Press twice to choose the
monitor/frequency monitor.
6.
Apply a voltage across the inverter
terminals 2-5 (across 4-5) and turn on the
start command (STF, STR).
Operation starts at 60Hz.
REMARKS
1. Changing C4 (Pr. 903) or C5 (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.
2. For the operation procedure using the parameter unit (FR-PU04), refer to the FR-PU04 instruction manual.
3. 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 62)
4. Make the bias frequency setting using calibration parameter C2 (Pr. 902) or C5 (Pr. 904). (Refer to page 130)
Take care when setting any value other than "0" as the bias speed at 0V (20mA). Even if a speed command
is not given, merely turning on the start signal will start the motor at the preset frequency.
