Speed setting by analog input (terminal 2, 4)
4
PARAMETERS
(c) Adjusting only the speed without adjusting the gain voltage (current).
(When changing the gain speed from 3000r/min to 1500r/min)
Operation Display
1. Turn until (Pr.125) or
(Pr.126) appears
or
Terminal 2 input is
selected
Terminal 4 input is
selected
2. Press to show the currently set value.
(3000r/min)
3. Turn to change the set value to
" ". (1500r/min)
4. Press to set.
Terminal 2 input is
selected
Terminal 4 input is
selected
Flicker...Parameter setting complete!!
5. Mode/monitor check
Press twice to choose the monitor/speed
monitor.
6. Apply a voltage across the drive unit terminals
2-5 (across 4-5) 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 value.
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 174)
CAUTION
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.
NOTE
Under position control, the bias and gain settings for the speed setting voltage (current) are invalid.
