dnMotorRefOffset_p

DINT

Home position in [increments]

• Value is adopted when control bit 9 ("HomeSetPos") is set from "0" to "1" in the

MCK control word

and is sent to the motor control function via the

dnMotorRefOffset_p_ output.

• Transfer is possible in any operating mode ("Homing on the fly").

• For this function, the two outputs bMotorRefOffsetOn_ and

dnMotorRefOffset_p_ must be connected to the inputs of the same name of

the

LS_MotorInterface

system block.

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.
