Outputs

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

nInertiaAdapt_a

C00830/96

| INT

(from version 12.00.00)

Adaptation of the moment of inertia

• This process signal can be used during the process to dynamically control the

percentage of the variable moment of inertia (e.g. a reel) set in

C00919/1

which

is to be considered for setpoint feedforward control.

• Scaling: 16384 ≡ 100 % moment of inertia - process (

C00919/1

)

bBrakeChopperOn

C00833/130

| BOOL

(from version 12.00.00)

Switch on the internal brake chopper as "brake chopper slave" (

C02866/3

= "1: Yes")

when the controller is configured

Control of multiple internal brake choppers in the DC-bus system ( 278)

TRUE Switch on internal brake chopper.

nSpeedSetValueInertia_a

C00830/97

| INT

(from version 12.00.00)

Input for differential setpoint feedforward control (torque feedforward control)

• If the selection "1: nSpeedSetValueInertia_a" is set in

C00654/1

, this process

signal can be used to preselect any input value (e.g. setpoint of the position or

process controller) for torque feedforward control.

• Scaling: 16384 ≡ 100 % reference speed (

C00011

)

Identifier

Value/meaning

bLimPosCtrlOut

BOOL

"Position controller output inside the limitation" status signal

TRUE The position controller output is internally limited

nOutputPosCtrl_a

INT

Position controller output

• Scaling: 16384 ≡ 100 % reference speed (

C00011

)

dnMotorPosAct_p

DINT

Current position of the motor shaft in [increments]

dnMotorDeltaPosAct_p

DINT

Current following error in [increments]

• Following error = Difference between set position and actual position

bLimSpeedCtrlOut

BOOL

"Speed controller or manipulating variable of the slip regulator inside the limitation"

status signal

TRUE The speed controller output is internally limited

bLimSpeedSetVal

BOOL

"Reduction or increase of the setpoint speed active" status signal

TRUE Reduction or increase of the setpoint speed by the I

max

controller is

active

wMaxMotorSpeed

C00011

| BOOL

Reference speed (

C00011

)

nOutputSpeedCtrl_a

INT

Speed or slip controller output

• Scaling: 16384 ≡ 100 % reference speed (

C00011

)

nSpeedCtrlIAct_a

INT

Current value of speed controller integrator

• Scaling depends on the selected motor control:

• V/f control (VFCplus + encoder):

16384 ≡ 100 % reference speed (

C00011

)

• Servo control (SC) or vector control (SLVC):

16384 ≡ 100 % M

max

(

C00057

)

nEffSpeedSetValue_a

INT

Effective speed setpoint

• Scaling: 16384 ≡ 100 % reference speed (

C00011

)
