A)
Increase in the reference by values of less than
Par. 630
Par. 630
= 300 rpm (prohibited speed threshold)
Par. 632
= 10 rpm (thus prohibited band: 290rpm.310rpm)
Set speed reference = 295 rpmHz
Output speed = 290 rpm
Set speed reference = 305 rpm
Output speed = 290 rpm
B)
Decrease in the reference by values above
Par. 630
Par.630
= 300 rpm (prohibited speed threshold)
Par.632
= 10 rpm (thus tolerance band: 290 rpm…310 rpm)
Set speed reference = 305 rpm
Output frequency = 310 rpm
Set speed reference = 295 rpm
Output frequency = 310 rpm
The user can thus set any reference value, but if the set value is within the prohibited range, the drive auto-
matically maintains the speed outside the limits defined by the tolerance band.
During ramp phases the prohibited speed is passed freely and there are no points of discontinuity in the gen-
eration of the output frequency.
The speed reference supplies the desired speed to the drive, which directly follows the reference pattern. This
only happens when the available torque is sufficient. In this case the drive functions at its current limit, until
reaching the set speed. The speed reference value determines the motor speed value. The sign determines
the direction of rotation.

Setting of the digital speed references. The overall speed reference is the result of the sum of the values with
the respective signs, of
Dig speed ref 1
and
Dig speed ref 2
. The digital speed references are linked to the
ramp circuit output.
The overall speed reference is the result of the sum of the values, with sign, of
Speed ref 1
and
Speed ref 2
.
Example 1:
Speed ref 1
= + 500 rpm
Speed ref 2
= + 300 rpm
Speed ref
= 500 rpm + 300 rpm = 800 rpm
