17. Control Mode (feed-back)

The Control Mode (feed-back) type has already configured in line with customer requirements that are defined

in the Order Code. The Order Code is written on the identification label.

However, if you wish to change the Control Mode (feed-back) type you can use the software configurator or

the Control Panel.

Caution: this procedure must be performed only by qualified persons.

The Control Mode (feed-back) type is defined by the parameter Control Mode (feed-back) in setup menu.

If the configurable digital input has set like feed-back Selection, it’s possible to change the select feed-back

with the Voltage feed-back (V) simply activating the input.

It’s possible to have:

= Square Voltage feed-back.

The input signal is proportional to the output square voltage. This means that input signal becomes a power

demand. The power remains constant if the load impedance doesn’t change.

= Voltage feed-back.

The input signal is proportional to the output voltage. This means that input signal becomes a voltage demand.

This control mode compensates the voltage fluctuation of the incoming line supply.

= Current feed-back.

The input signal is proportional to the current output. This means that input signal becomes a current demand.

This control mode maintain the current also if the load impedance changes.

P(VxI)

= Power feed-back.

The input signal is proportional to the power output. This means that input signal becomes a power demand.

The power remains constant also if voltage and load impedance change. This control mode is used with silicon

carbide elements that change its resistive value with temperature and with age. In addition it compensates the

voltage fluctuation of the incoming line supply.

= Square Current feed-back.

The input signal is proportional to the output square curren. This means that input signal becomes a power

demand. The power remains constant if the load impedance doesn’t change.

None

= No feed-back Open Loop. The input is proportional to the firing angle (α).

External

= External feed-back (0÷10V, 4÷20mA, 0÷20mA).

The input signal is proportional to an external signal. This means that input signal becomes a demand to

maintain this signal always constant. This control mode is used for example with galvanic systems, where it’s

necessary to control the current value through the electrodes.
