This parameter sets the mode for the amplifier group 1 (includes the first three amplifiers 1,2 and 3).

INDEPENDENT - With this mode selected, each amplifier output can be activated individually. i.e. the enable contactor can be individually controlled for each amplifier. It has an option to enable grouped operation by checking the grouped Operation checkbox. With this checkbox checked, all the three amplifiers are activated together i.e. the enable contactors of three amplifiers are controlled together. This mode is suitable for three-phase applications.

DIFFERENTIAL - With this mode selected, the first two amplifiers (Amp 1 and 2) are controlled together as a single amplifier. The reference provided to amplifier 1 is used and the one for amplifier 2 is ignored. The voltage produced at the output is created between amplifier 1 and amplifier 2. Amplifier 3 input reference is ignored as well.

This parameter sets the mode for the amplifier group 2 (includes the second three amplifiers 4,5 and 6).

AMPLIFIER X ENABLE MODE

This parameter allows you to select if the amplifier output activation (i.e, engaging the output contactor) is controlled by the corresponding port in the block or by the graphical user interface (GUI) OP8110-6 Console GUI/wiki/spaces/POMT/pages/42962376block in the console.

GUI OUTPUT ENABLE - With this selected, the amplifier 'x' output is activated from the GUI in the console.

MODEL OUTPUT ENABLE - With this selected the amplifier 'x' output is activated from the Amp x Enable input port of the block.

Check this box if you would like to bypass the 75 uH inductance at the output. 

Un-check if you need to keep the inductance in the circuit. The option is checked by default.

This input is used to pass the voltage output reference to amplifier X. The value directly corresponds to the output voltage of the amplifier (with respect to the phase neutral). If the amplifier group operates in DIFFERENTIAL mode, this input corresponds to the output voltage between amplifier phase L1 and amplifier phase L2.

For details of maximum voltages possible in each mode, please consult OP8110 4Q Power Amplifier in Specialized Solutions Documentation.
