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 have no function on the 8400 protec StateLine!
nTorqueLimitAdapt_a
Control words
MCK: wMotionCtrl1
wMotionCtrl2
Inputs have no function on the 8400 protec StateLine!
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 have no function on the 8400 protec StateLine!
nSpeedAddValue_v
nSpeedOverride_a
nAccOverride_a
nSRampOverride_a
bLimitSwitchPos
bLimitSwitchNeg
bHomingMark
bBrkRelease
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).
• During automatic operation, the internal brake logic is
deactivated and the brake is released. If the brake control has
inhibited the controller, this inhibit is deactivated again.
bBrkStartValue2 Inputs have no function on the 8400 protec StateLine!
