bDcBrakeOn

BOOL

Manual DC-injection braking (DCB)

• For this function, the bDcBrakeOn_ output signal must be connected to the

bDcBrakeOn input of the same name of the

LS_MotorInterface

system block.

• Detailed information on DC-injection braking is provided in the motor control

chapter, subchapter "

DC-injection braking

".

Note!

Holding braking is not possible when this braking mode is used!

Use the basic "

Holding brake control

" function for controlling the holding brake with

a low rate of wear.

FALSE Deactivate DC-injection braking.

TRUE Activate DC-injection braking, i.e. the drive is brought to a standstill

by means of DC-injection braking.

• The braking effect stops when the rotor is at standstill.

• After the hold time (

C00107

) has expired, the controller sets the

pulse inhibit.

bTorqueLimitAdaptOn

Inputs of 8400 StateLine have no function!

nTorqueLimitAdapt_a

Control words

MCK: wMotionCtrl1

wMotionCtrl2

Inputs of 8400 StateLine have no function!

wAuxCtrl

wSMCtrl

WORD

Interface to the optional safety system.

• Setting control bit 0 ("SafeStop1") in this control word causes e.g. the automatic

deceleration of the drive to standstill within this application (in the Motion

Control Kernel).

• See the "

Interface to safety system

" subchapter for a detailed description of the

individual control bits.

Control and setpoint signals for Motion Control Kernel function

dnProfilePosition_p

Inputs of 8400 StateLine have no function!

nSpeedAddValue_v
nSpeedOverride_a
nAccOverride_a
nSRampOverride_a
bLimitSwitchPos
bLimitSwitchNeg
bHomingMark

bMBrakeRelease

BOOL

Holding brake control

:

Releasing/applying the brake in connection with the selected operating mode

FALSE Apply brake.

• During automatic operation, the internal brake logic controls the

brake.

TRUE Release brake manually (forced release).

Note!

The brake can also be released if the controller is inhibited!

• During automatic operation, the internal brake logic is

deactivated and the brake is released (supervisor operation). If a

controller inhibit has been set by the brake control, it will be

deactivated.

• In semi-automatic operation, the brake is released including

feedforward control.
