bQspOn
BOOL
Trigger quick stop (QSP) via the MCK
• Also see device command "Activate/deactivate quick stop
".
TRUE Activate quick stop
• Motor control is decoupled from the setpoint selection and,
within the deceleration time parameterised in C00105
, the motor
is brought to a standstill (n
act
=0).
• A pulse inhibit is set if the auto-DCB function has been activated
via C00019
.
• The motor is kept at a standstill during closed-loop operation
(function in preparation).
FALSE Deactivate quick stop
• The quick stop is deactivated if no other source for the quick stop
is active.
• C00159
displays a bit code of active sources/causes for the quick
stop.
nPWMAngleOffset
INT
Angular offset input
• Scaling: 16384 ≡ 100 %
• Setting range: 0 ... 199.99 %
bSpeedCtrlIOn
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
INT
I-component of the speed controller
• Value is adopted in the case of a FALSE-TRUE edge at the input bSpeedCtrlIOn.
nSpeedSetValue_a
INT
Rotation speed/velocity setpoint
bTorquemodeOn
BOOL
TRUE Switch on torque-controlled operation
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!
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
BOOL
Adaptation of torque limitation
TRUE Activate adaptation of torque limitation.
nTorqueLimitAdapt_a
INT
Value for adaptation of torque limitation
• Scaling: 16384 ≡ 100 % of the torque limit specified at the LS_MotorInterface
system block via the nTorqueMotLimit_a and nTorqueGenLimit_a inputs.
