Adjustment
1. In C0425, enter the frequency, resolution, scanning time and type of setpoint signal
(single−track, two−track) (C0425).
2. In C0426, select a gain which ensures that the input frequency corresponds to the
normalisation frequency at maximum process motor speed.
– The gain always acts both on the setpoint signal and the offset.
– 100 % corresponds to a gain factor = 1.

Normalisation frequency from C0425
p Pole pair number of the motor
z Number of encoder increments
C0011 Maximum output frequency (corresponds to
maximum process motor speed)
3. Set offset if required (C0427).
– An offset will shift the characteristic.
Setting tips
ƒ In case of higher accuracy requirements, select a higher resolution in C0425.
ƒ A two−track frequency signal serves to evaluate the direction of rotation of the
motor.

Note!
The setting for the minimum output frequency (C0010) is not effective.
