Emerson FXMP25 - Field Control and Mode Parameters

40 FXMP25 User Guide
www.controltechniques.com Issue Number: 3
When this parameter is set to 1 the field controller operates in voltage mode. A fixed
voltage is applied to the field rather than the current being regulated.
The parameter indicates the average AC supply rms voltage at the input terminals.
Filtered by a 100 ms first order filter.
When this parameter is set to OFF (0) the field controller is disabled. Setting this
parameter to On (1) enables the field controller.
Provide the option for operating mode and full or half bridge control
Pr 78 = 0--- No mode select (OFF)
Pr 78 = 1--- Mentor MP mode (M P)
Pr 78 = 2--- Mentor II mode, half control (2.H)
Pr 78 = 3--- Mentor II mode, full control (2.F)
Pr 78 = 4--- Stand alone, half control (St.H)
Pr 78 = 5--- Stand alone, full control (St.F)
A reset is required for the mode change to take effect and the command to be passed
through to the power processor. A reset can be achieved by holding the mode key for 2
seconds.
