3.2.44.1 Setpoint conditioning with stretch and gearbox factor
Stretch factor
Defines the ratio between the drive and the setpoint.
l The stretch factor evaluates the setpoint at DFSET−IN. DFSET−POUT outputs the result.
l The stretch factor results from numerator and denominator.
– Numerator is variable from analog signal source or fixed value by the code.
– Input of the denominator under C0533.
l Relationship:
DFSET–POUT + DFSET–IN @ DFSET–VP–DIV
C0533
Gearbox factor
Defines the transmission ratio of the drive. Enter the ratio of the drive.
l The gearbox factor evaluates the setpoint at DFSET−IN multiplied by the stretch factor.
DFSET−NOUT outputs the result.
l The gearbox factor results from numerator and denominator.
– Numerator is variable from analog signal source or fixed value by the code.
– Input of the denominator under C0033.
l Relationship:
DFSET–NOUT + Reckfaktor @ DFSET–RAT–DIV
C0033
DFSET–NOUT + DFSET–IN @ DFSET–VP–DIV
C0533
@ DFSET–RAT–DIV
C0033
Deactivate the gearbox factor and the DFSET−N−TRIM values as a basis for the setpoint angle
integrator. If C0530 = 1, only the stretch factor is used for setpoint angle calculation.
3.2.44.2 Processing of correction values
Speed trimming
This is used to add correction values, e.g. by a superimposed control loop. This enables the drive to
accelerate or decelerate.
l Adds an analog value at DFSET−N−TRIM to the setpoint speed.
(see code C0537)
l Adds a speed value at DFSET−N−TRIM2 to the setpoint speed.
– The speed trimming via this input is more precise.
(see code C1258)
