Control Modes - Advanced Energy THYRO-AX Manual

42
The values of the default settings are:
• setpoint configuration 1 (no ground to terminal X22.1)
o analog signal 1
o analog signal 2
o digital signal from digital potentiometer
• setpoint configuration 2 (alternative - ground to terminal X22.1)
o digital signal from USB or bus interface
INPUTS FOR SWITCH MODE SWITCH
For the switch mode SWITCH it is possible to switch via a 24 V signal
(5-24 V) as a digital signal to terminal X2.7 (Sync. In Digital In) or via
the setpoint on the basis of a threshold. A digital switching signal or an
overall setpoint from 50% causes a switching on, below this a switching
off.

6.3 CONTROL MODES

Thyro-AX provides various types of control. The control has an influence
on the size of the output of the power controller. Before commissioning
the power controller and selection of a control mode the mode of func-
tionality and effect on the application should be known.

Mains voltage variations and load alterations are compensated directly
and, as a result, quickly by bypassing the inert temperature regulation
circuit (secondary control).

CONTROL CHARACTERISTICS AND CONTROL VARIABLE
The control variable influencing the load is proportional to the effective
setpoint in the case of control modes U, I, P. In control modes U
the control variable influencing the load is a square of the effective
setpoint.
