f-max
0.0 Hz
5 x P-09
Determines the maximum output frequency.
This can be set to any value between “f-min” (P-
02) and 5x the “Motor Nom Frequency”, set with P-
09. When “Motor Nom Frequency” (P-09) is
changed, P-01 is set to the value of P-09.
“Motor Nom Speed” (P-10) = 0, Displays max.

0.0 Hz
P-01
Determines the min. output frequency.
This can be set to any value between 0 and “f-
max” (P-01). When “Motor Nom Frequency” (P-09)
is changed, P-01 is set to zero.
“Motor Nom Speed” (P-10) = 0, Displays min.

0.0 Hz
P-03
t-acc
0.0 s
600 s
Sets the acceleration ramp time in seconds.
The time interval set in “t-acc” represents the time
taken to accelerate from zero to “Motor Nom
Frequency” (P-09).
5.0 s
P-04
t-dec
0.0 s
600 s
Sets the deceleration ramp time in seconds.
The time interval set in ”t-dec” represents the time
taken to decelerate from “Motor Nom Frequency”
(P-09) to zero.
5.0 s
P-05
Stop mode
0
3
Determines the action taken by the drive in the
event of the drive enable signal being removed.
0: Ramp. When the enable signal is removed, the
drive will ramp to stop, with the rate controlled by
“t-dec” (P-04).
1: Coasting. When the enable signal is removed,
the drive output is immediately disabled, and the
motor will coast (freewheel) to stop.
2 : Ramp. When the enable signal is removed, the
drive will ramp to stop, with the rate controlled by
“t-dec” (P-04). If the mains supply is lost, the drive
will ramp to stop using the deceleration ramp set
by P-24. Condition: P-24 is set to a time that is
shorter than the one for discharging the DC link.
Otherwise the drive will trip due to "under
voltage".
3: AC flux braking. When stopping the drive, AC
flux braking is used to reduce the stopping time.

EnergyOptimizer

1
When energy optimization is activated, the motor
voltage is dynamically varied, dependent on load.
This results in reduced voltage being applied to the
motor on light load, significantly reduce energy
consumption.
This mode of operation is less suitable for dynamic
applications where the load conditions can
suddenly increase significantly.
