nTorqueSetValue_a
INT
Torque setpoint
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!
For controlling a holding brake with low rate of wear, use the basic function "Holding
brake control".
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 (CINH).
bTorqueLimitAdaptOn Inputs have no function on the 8400 StateLine!
nTorqueLimitAdapt_a
Control words
MCK: wMotionCtrl1
wMotionCtrl2
Inputs have no function on the 8400 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 StateLine!
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 of
the brake.
TRUE Release brake manually (forced release).
• Note!
The brake can also be released when the controller is inhibited!
• During automatic operation, the internal brake logic is
deactivated and the brake is released (supervisor operation). If
the brake control has inhibited the controller, this inhibit is
deactivated again.
• In semi-automatic operation, the brake is released including
feedforward control.
