2. Set the accel/decel times in parameters C1-12 and C1-13 w hen using m otor 2.
3. W hen m otor 2 is selected, the following monitors will display values in Hz: U1-01, U 1-02, U1-05, U 4-19, U4-20.
■ d1-28: Leveling Speed Detection Level
When the speed priority selection in d1-18 is set to “0” or “3” and the speed reference value falls below the level set in
d1-28, the drive interprets the selected speed as leveling speed. This parameter must be set to use the Speed Control Loop
setting 3 when d1-18 = 0/3. Refer to
C5: Speed Control Loop on page 150

When the speed priority selection in d1-18 is set to “0” or “3” and the speed reference value is below the level set in d1-
29 but higher than the level set in d1-28, the drive interprets the selected speed as inspection speed. This parameter must
be set to use the Inspection Operation function when d1-18 = 0/3. Refer to

♦ d6: Field Forcing
Field Forcing
The Field Forcing function compensates the delaying influence of the motor time constant when changing the excitation
current reference. Field Forcing can improve the motor responsiveness. It is ineffective during DC Injection Braking.
■ d6-03: Field Forcing Selection
Enables or disables the Field Forcing function.
