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)
.
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.
