7.6.34.1 Setpoint conditioning with stretch and gearbox factor
Stretch factor
Defines the ratio between the drive and the setpoint.
l The stretch factor evaluates the setpoints 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 ô
DFSET–VP–DIV
C0533
Gearbox factor
Defines the gearbox ratio of the drive. Enter the ratio of the drive.
l The stretch 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.

7.6.34.2 Processing of correction values
Speed trimming
This is used to add correction values, e.g. by a superimposed closed-loop control. This allows
acceleration or deceleration of the drive.
l Adds an analog value at DFSET-N-TRIM to the setpoint speed.
l Adds a speed value at DFSET-N-TRIM2 to the setpoint speed.
– The speed trimming via this input is more precise.
Phase trimming
Adds a setpoint at DFSET-A-TRIM to the setpoint phase. This changes the rotor position to the
setpoint with the number of increments provided (drive leading or lagging). The phase trimming is
performed within a range of ±32767 increments (
±1/2 revolution). The source can be any analog
signal.
l The input is done in increments (one revolution 65536 increments).
l When analog values are entered, 100% correspond to 1/4 revolution = 16384 increments.
l Extension of the setting range with a multiplier under C0529.
Phase offset
Addition of a fixed phase offset under C0252 to the setpoint of the drive.
