24 ADV200 • Functions description and parameters list

5–REFERENCES

ADV drives are provided with a speed regulation circuit, which can be adapted to suit the various applications. In the

standard version, the regulator has PI behaviour and the regulator parameters are the same for the entire eld of regu-

lation.

Different sources can be used for the speed and torque references, depending on how the 554Controlmodeselect

parameter is set.

5.1 600 Digrampref1 FF INT16 16/32 0 CALCI CALCI RW FVS

Setting of the digital ramp reference. The speed that the drive must reach after completing the acceleration

phase is set with the ramp reference. Variations in the ramp reference are made with the selected ramp times.

The size of the ramp reference determines the motor speed value. The sign determines the direction of rota-

tion. The Rampref parameter also refers to a minimum speed, if set. When the “Motorpotentiometer” or

“Multispeed” functions are selected the relative references are used. This reference can only be used in the

Remote mode.

The overall ramp reference is the result of the sum of the values with the Rampref1 and Rampref2 sign.

Example 1: Rampref1 = + 500 rpm Rampref2= + 300 rpm

Rampref= 500 rpm + 300 rpm = 800 rpm

Example 2: Rampref1 = + 400 rpm Rampref2 = - 600 rpm

Rampref = 400 rpm – 600 rpm = - 200 rpm

Setting of the digital ramp reference. The speed that the drive must reach after completing the acceleration

phase is set with the ramp reference. Variations in the ramp reference are made with the selected ramp times.

The size of the ramp reference determines the motor speed value. The sign determines the direction of rota-

tion. The Rampref parameter also refers to a minimum speed, if set. When the “Motorpotentiometer” or

“Multispeed” functions are selected the relative references are used.

In Remote mode the overall ramp reference is the result of the sum of the values with the Ramp ref 1 and

Ramp ref 2 sign.

Example 1: Rampref1 = + 500 rpm Rampref2 = + 300 rpm

Rampref = 500 rpm + 300 rpm = 800 rpm
