Mitsubishi Electric FR-D720-0.2K-G Instruction Manual page 159

Speed setting by analog input (terminal 2, 4)
(c) Adjusting only the speed without adjusting the gain voltage (current).
(When changing the gain speed from 3000r/min to 1500r/min)
Operation
1.
Turn until "
" " (Pr. 126) appears
2.
Press to show the present set value.
(3000r/min)
3.
Turn to change the set value to
" ". (1500r/min)
4.
Press to set.
5.
Mode/monitor check
Press twice to choose the monitor/
speed monitor.
6.
Apply a voltage across the drive unit terminals
2 and 5 (across 4 and 5) and turn ON the start
command (STF, STR).
Operation starts at 1500r/min.
REMARKS
 Changing C4 (Pr. 903) or C7 (Pr. 905) (gain adjustment) value will not change the Pr. 20 Acceleration/deceleration reference speed
setting.
 For operation from the parameter unit (FR-PU07), refer to the Instruction Manual of the FR-PU07.
 Make the bias speed setting using the calibration parameter C2 (Pr. 902) or C5 (Pr. 904). (Refer to page 153.)
Be cautious when setting any value other than "0" as the bias speed at 0V (0mA). Even if a speed command is
not given, merely turning ON the start signal will start the motor at the preset speed.
