5.3 Controller Assembly

The Controller Assembly is located in the top section of the MX unit. To access this asse
the top cover needs to be removed. The controller assembly consists of three printed circuit
boards connected by a ribbon cable. The controller contains the main oscillator, which
generates the sine wave signal setting the frequency, amplitude and current limit level. It also
senses the output voltage to provide closed loop control of the output. The controller
handles all user interface and remote control related tasks.

MX Series I models use a three board set controller. On Series II models, the controller uses a
two board set instead (7003-718-

mbly,

also

2 or 7003-718-4 assembly). The function of each of the boards

5.3.1 C

that make up the controller module is described in the following paragraphs.

PU Controller

This board assembly, A2-A7, consists of the components for the CPU (DSP), generating the
Phase waveform signal to the power amplifier, programmable impedance (MX30-3Pi or MX45-
3Pi model only) and all of the program, waveform and data memory. In addition, the wavefo
board contains the circuits for all measurements. The clock and lock circuit required to suppo
the clock and lock mode of operation of multiple MX units is also on this board assembly.

On MX Series I units, this board contains only Phase A circuitry in addition to the CPU logic. On
MX Series II unit, all three phases are contained on the same board. If the -413 option is
present, a separate inter harmonic ge

rm

rt

nerator board is connected to the CPU board.

y)

5.3.2 Phase B and C Board (MX Series I onl

This assembly, A8, has the waveform, measurement and impedance programming componen
for the Phase B and C power modules. This board is not installed in an MX45-1 single-phase
power system but is present for all other configurations.

5.3.3 K

The keyboard/display assembly is assembly A2-A9. It is mounted to the front panel and holds
the 23 rubber k

eys. It also has the LCD graphics display. A shaft encoder is mounted on the

ewing of setup parameters. If the MX system is

rol interfaces, the keyboard functions can be locked out by

asserting the REMOTE state. See the MX Series Programming Manual (P/N 9003-961) for
