Function:
[0 - Shows the alarm word of a user-
defined alarm in hex code.
Function:
[0 - Shows the warning word of a user-
defined alarm in hex code.
Function:
[0 - Shows the status word of a user-
defined alarm in hex code.
Function:
Select the switching pattern: 60°
AVM or SFAVM.
Function:
Select the inverter switching
frequency. Changing the switching
frequency can help reduce acoustic
noise from the motor.
NOTICE
The output frequency value of
the frequency converter must
never exceed 1/10 of the
switching frequency. When the
motor is running, adjust the
switching frequency in
parameter 14-01 Switching
Frequency until the motor is as
noiseless as possible. See also
parameter 14-00 Switching
Pattern. For information about
derating, see the relevant
design guide.

16.0kHz
Function:
Off Selects no overmodulation of the
output voltage to avoid torque
ripple on the motor shaft.
On The overmodulation function
generates an extra voltage of up to
8% of U output voltage without
max
overmodulation. This extra voltage
results in an extra torque of 10–
12% in the middle of the oversyn-
chronous range (from 0% at
nominal speed, rising to approxi-
mately 12% at double nominal
speed).
Function:
Off No change of the acoustic motor
switching noise.
On Select to reduce the acoustic noise
from the motor.
Function:
Select the function at which the
frequency converter must act, when
the threshold set in
parameter 14-11 Mains Fault Voltage
Level has been reached or a mains
failure inverse command is
activated via 1 of the digital inputs
(parameter group 5-1* Digital Inputs).
Only selection [0] No function, [3]
Coasting, or [6] Alarm is available
when parameter 1-10 Motor
Construction is set to [1] PM non-
salient SPM.
