nBoost_a

C00830/26

| INT

Process signal for the V

min

boost

• This signal is added to

C00016

and has thus an increasing or decreasing effect.

• This signal serves to implement a load-dependent Vmin boost to improve the

torque behaviour in different load states, as for instance in case of operation in

generator or motor mode.

• Scaling: 16384 ≡ 100 % rated device voltage V

FU

(400 V or 230 V)

Adapting the Vmin boost ( 135)

Stop!

Values selected too high may cause the motor to heat up due to the resulting

current!

bQspOn

C00833/33

| BOOL

Quick stop

FALSE Deactivate quick stop

TRUE Activate quick stop

nPWMAngleOffset_a

C00830/32

| INT

Angle step change of output voltage phasor

• Scaling: 65535 ≡ 1 revolution

bSpeedCtrlIOn

C00833/31

| BOOL

Directly set the I-component of speed controller

• In order to statically specify a minimum torque, e.g. when a load is being lifted.

TRUE Se the I-component of the speed controller to the value

nSpeedCtrlI_a.

nSpeedCtrlI_a

C00830/24

| INT

Value of the speed controller integrator

• Scaling depends on the selected motor control:

• V/f control (VFCplus + encoder):

16384 ≡ 100 % reference speed (

C00011

)

• Vector control (SLVC):

16384 ≡ 100 % M

max

(

C00057

)

nSpeedSetValue_a

C00830/22

| INT

Speed setpoint

• Scaling: 16384 ≡ 100 % reference speed (

C00011

)

bTorquemodeOn

C00833/30

| BOOL

Selection: Speed/Torque control

FALSE Speed control with torque limitation

TRUE Torque control with speed limitation

nTorqueSetValue_a

C00830/27

| INT

Torque setpoint / additive torque

• Scaling: 16384 ≡ 100 % M

max

(

C00057

)

bDcBrakeOn

C00833/34

| BOOL

Activate DC injection brake

FALSE Deactivate DC-injection braking

TRUE Activate DC-injection braking

bTorqueLimitAdaptOn

C00833/98

| BOOL

Adaptation of torque limitation

TRUE Activate adaptation of torque limitation.

nTorqueLimitAdapt_a

C00830/70

| INT

Value for adaptation of torque limitation

• Scaling: 16384 ≡ 100 % nTorqueMotLimit_a and nTorqueGenLimit_a
