RUN
1 TYPE CTRL=V/Hz
G19.1.1 /
Selection of
control type
V/Hz
PEVE
This selection defines the drive control type.
OPT.
FUNCTION
V/Hz
Scalar control mode. Drive carries out the control
applying a voltage / frequency ramp to the motor.
PEVE
Automatic compensation of stator voltage using
the PEVE algorithm to improve the torque
delivery.
CLsp
Closed loop speed control mode. Makes a full
control of the motor speed. Needs encoder.
CLtq
Makes a full control of motor torque Needs
encoder.
YES
2 FRQ=4000Hz
MODULAT FREQUENC
G19.1.2 /
Commutation
frequency
4000 – 8000
Hz
It allows modification of the inverter‟s bridge switching frequency. This function
can be used to reduce audible motor noise.
YES
3 PEWAVE=Y
G19.1.3 /
Pewave control
N
Y
This control mode improves motor noise tone.
OPT.
FUNCTION
N=NO
Pewave control deactivated.
Y=YES
Pewave control activated.
Inverter‟s bridge switching frequency (G19.1.2) is
slightly modified on a random basis to improve
the noise tone generated by the motor.
YES
5 AUTOTUNE=N
G19.1.5 / Motor
parameter auto-
tuning
N
Y
This selection allows executing a motor auto-tuning, in order to get the stator
resistance value of the motor. This value will be saved in parameter G19.3.1.
YES
6 OVERMODULATIO=N
G.19.1.6 /
Over-modulation
N
Y
With this option, it allows supplying more motor voltage at 50Hz.
YES

RUN
1 MIN FLUX = 100%
MINIMUM FLUX
G19.2.1 /
Minimum Flux
40 – 100%
Allows setting of the minimum flux level used by the motor during low load
conditions. With this dynamic system of flux optimization, noise and power losses
are reduced. Adaptation of the flux level during low load conditions occurs
automatically. The algorithm will be disabled when this parameter is set to 100%.
YES
2 BW BOOST=0.0%
BOOST BAND
G19.2.2 / Torque
boost band
0.0 – 100%
It sets a frequency band or range on which torque set in previous parameter will
be applied during the start.
YES
3 V BOOST = 0.0%
BOOST VOLTAGE
G19.2.3 / Initial
voltage
0.0 – 100%
Sets an initial voltage value applied to the motor during the starting. Using this
function it is possible to improve breakaway torque when starting heavy loads.
This parameter is used in association with parameter 'G19.2.2 BW BOOST'.
Note: Set a low value first. Increase the value gradually until the load starts easily.
YES
4 SLIP COMPENS=N
G19.2.4 / Slip
compensation
N
Y
If this function is active, it helps to compensate the slip on the motor. In case of
heavy load able of provoking a high slip during the starting, set this parameter to
YES.
YES
