Outputs

nSpeedTrim_v

INT

Speed trimming in [increments/ms]

• Scaling: 16384 ≡ 15000 rpm

• Speed trimming via this input is more precise.

dnPosOffset_p

DINT

Angular offset in [increments]

• Scaling: A motor revolution is mapped with 65536 increments or steps.

nPositionTrimming

INT

Angular trimming in [increments]

• Scaling: A motor revolution is mapped with 65536 increments or steps.

• When analog values are selected: 100 % ≡ 1/4 revolution ≡ 16384 increments

• The setting range can be extended via

C01072/1

.

nSet_v

INT

Speed setpoint

• Scaling: 16384 ≡ 15000 rpm

wGainNum

WORD

Stretch factor (numerator)

wGainDenom

WORD

Stretch factor (denominator)

wGearNum

WORD

Gearbox factor (numerator)

wGearDenom

WORD

Gearbox factor (denominator)

bSetActIntegrator

BOOL

Equalise angle integrators (current position = set position)

• This input has a higher priority than the bResetAllIntegrators input.

FALSETRUE Set following error dnDeltaPos_p = 0.

TRUE Equalise angle integrators.

bResetAllIntegrators

BOOL

Reset angle integrators

TRUE Positional deviation, dnPosSetOut_p and dnDeltaPos_p are set to "0".

nNAct_v

INT

Actual value in [increments/ms] for calculating the actual position

• Scaling: 16384 ≡ 15000 rpm

• If this input is connected or assigned to an output, the following error created

from integration of this input and difference with the set position is used for the

following error compensation in case of mark correction.

Value/meaning

bAck

BOOL

Status signal "Synchronising is executed"

TRUE Synchronising is executed.

dnPosDiffOut_p

DINT

Angular offset in [increments]

• Difference between two positions measured by means of touch probe.

nSetGain_v

INT

Speed setpoint in [increments/ms] evaluated with stretch factor

• Scaling: 16384 ≡ 15000 rpm

nSetGearTrim_v

INT

Speed setpoint in [increments/ms] evaluated with stretch factor and gearbox factor

• Scaling: 16384 ≡ 15000 rpm

nSetGearTrim_a

INT

Speed setpoint in [%] evaluated with stretch factor and gearbox factor

• Scaling: 16384 ≡ 100 % reference speed (

C00011

)

nSpeedSetOut_v

INT

Speed setpoint in [increments/ms]

• Scaling: 16384 ≡ 15000 rpm

• Derived from angle setpoint dnPosSetOut_p.

• Can change abruptly if e.g. the angular offset changes abruptly.

dnDeltaPos_p

DINT

Following error between setpoint position and actual position in [increments]

• This output can be used for display purposes.
