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 automati-

cally maintains the speed outside the limits dened 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 sufcient. 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

Example 2: Speed ref 1 = + 400 rpm Speed ref 2 = - 600 rpm

Speed ref = 400 rpm – 600 rpm = - 200 rpm
