r1583

CO: Flux setpoint (smoothed)

Min: -

Datatype: Float Unit:

Def:

Max: -

Displays smoothed flux setpoint in [%] relative to rated motor flux.

P1596[3]

Int. time field weak. controller

Min: 20

CStat:

CUT

Datatype: U16 Unit:

Def:

P-Group: CONTROL

Active: Immediately

P1596[1] : 2nd. Drive data set (DDS)
P1596[2] : 3rd. Drive data set (DDS)

r1597

CO: Outp. field weak. controller

Min: -

Datatype: Float Unit:

Def:

P-Group: CONTROL

Max: -

Displays output signal of field weakening controller in [%] relative to rated motor flux.

r1598

CO: Flux setpoint (total)

Min: -

Datatype: Float Unit:

P1610[3]

Continuous torque boost (SLVC)

Min: 0.0

CStat:

CUT

Datatype: Float Unit:

Def:

50.0

P-Group: CONTROL

Active: Immediately

QuickComm.: No

Max: 200.0

Sets the constant torque boost for the low frequency range when sensorless closed-loop vector control is
being used (SLVC). The parameter is entered as a % referred to the rated motor torque (r0333).

For sensorless closed-loop vector control, when the motor model is disabled, an absolute current is
impressed. P1610 represents the maximum load that occurs at a constant setpoint.

P1755

f(t)

(t)

(P1610, P1611)

P1610 = P1611 = 0

r0331

P0346

Index:

P1610[0] : 1st. Drive data set (DDS)
P1610[1] : 2nd. Drive data set (DDS)
P1610[2] : 3rd. Drive data set (DDS)

Caution:

P1610 should always be set at least 10% higher than the maximum steady-state load that occurs.

Note:

For P1610 = 0 %, a current setpoint is calculated that corresponds to the no-load case (rated
magnetization current).

For P1610 = 100 %, a current setpoint is calculated that corresponds to the rated motor torque.
