Product Overview

PRODUCT DESCRIPTION

General Description

The Advanced Energy Paramount MF 2 kW generator is a 360 kHz to 440 kHz
midfrequency generator designed to regulate on one of the following:

• Forward power

• Load power

• Voltage with an optional AE peak voltage sensor

The Paramount MF 2 kW generator provides up to 2000 W into a 50 Ω, nonreactive
load. The generator is capable of delivering 100% of its rated power into a 4.79:1
VSWR load, making it an ideal choice for applications with a fixed match.

2

The Paramount MF 2 kW generators incorporate Direct Digital Synthesis (DDS)
technology for control of the operating frequency. This technology can be useful
when the application requires that the selected generator operate into an impedance
mismatch. The frequency can be programmed to dither over a predetermined range to
minimize the load mismatch to the generator. The DDS operating parameters on each
generator are configured via the generator's serial communications interface and are
stored indefinitely in nonvolatile RAM.

The Paramount MF 2 kW generators are water and air cooled, 7" high, 19" rack­mountable units. Front panels with numeric displays and six status LEDs provide
basic generator monitoring. Primary control is accomplished through the generator's
serial and user communications interfaces.

THEORY OF OPERATION

Operation Overview

The Paramount MF 2 kW generator efficiently creates sinusoidal voltage waveforms
by switching rectified DC power through a filter and an isolation transformer. A
directional coupler/detector samples the RF power signal and uses the signal to
control the switch waveforms and therefore, the output power. Depending upon the
method of regulation, either the forward or load power can be used as a control

signal. The Paramount MF 2 kW generator can also control the voltage at the load
with proper voltage feedback and setting the unit to voltage control mode.

Figure 2‑1. Paramount MF 2 kW generator block diagram

Rectifier Module

The full-wave bridge rectifier converts the AC input voltage into a steady DC signal.
This power is provided directly into the inverter module.

Paramount® MF 2 kW Generator

Inverter Module

The inverter module is composed of a set of MOSFETs which are either fully on or
fully off. When the FETs are on, very little voltage drop occurs across them. When
they are off, virtually no current flows through them. Since the power dissipated in a
FET is the product of the voltage across and the current through the device, neither
case represents a large power loss. This makes the generator very efficient.

Isolation Transformer

The inverter module produces a waveform with substantial energy at the fundamental
switching frequency, which is set to the desired output frequency. This waveform
goes to the isolation transformer.

The isolation transformer isolates RF output of the generator from the inverter
module which is directly connected to the AC power line. The transformer also
transforms the impedance to bring the output impedance of the generator to a
standard 50 Ω level.

Filter

The filter is a combination of inductors and capacitors especially designed to pass
only the frequency of interest and reject high frequency harmonics (a lowpass filter).
The output of the filter is nearly a perfect sine wave. This wave is then delivered to
the directional coupler/detector.

57020114-00E Product Overview 2‑2

Advanced Energy

®

Directional Coupler/Detector

The directional coupler/detector samples the voltage and current of the RF power line
and a digital signal processor (DSP) is used to calculate the forward and reflected
power. The forward and reflected power can be thought of as the power flowing
toward the load and the power reflected back from the load. Forward power minus
reflected power is the power dissipated in the load and is called the load power. The
DSP uses the calculated values in the feedback control loop to control the power
supply output.

The Paramount MF 2 kW generator uses sophisticated signal processing to
compensate for or eliminate offsets and nonlinearities inherent in the generator. As a
result, the output power of the generator is accurate and linear. Forward, reflected,
and load power levels are displayed on the front panel and are provided to, or can be
accessed through, the generator's serial and user communication ports.

Voltage Control Mode

The Paramount MF 2 kW generator has the capability to control the amplitude of RF
output voltage at the load with the use of the AE Low Frequency Fixed Match and
voltage peak detector. The voltage from the peak detector is supplied to the generator
and used to control the inverter.

Paramount® MF 2 kW Generator

Controls

The control section controls the inverter that regulates the output power. This section
has limits and trip thresholds that prevent inverter failure.

POWER REGULATION

Regulation Overview

The Paramount MF 2 kW generator can regulate power based on either forward or
load power measurements. The method used by the generator is determined by User
port pin 8, referenced to pin 21 (FWD/LOAD POWER REGULATION). You can also
use command 3, set regulation mode, at the Host port to select the regulation mode.
The front panel display screen allows you to view operating data for forward,
reflected, and load power parameters.

Forward and Reflected Power

In a mismatched system, the load impedance does not match the connecting cable
impedance, which means there will always be a standing wave on the connecting
cable. Think of this standing wave as being created by the interference of two

57020114-00E Product Overview 2‑3

Advanced Energy

travelling waves, one moving toward the load and one returning to the generator. The
power in the imagined wave moving toward the load is the forward power, and the
power in the imagined return wave is the reverse, or reflected, power.

Mathematically, in a system with a reference (cable) impedance Z0, forward and
reflected voltages (V

The plus sign is used for forward voltage and current and the minus sign is used for
reflected voltage and current. The forward and reflected powers are the product of the
voltages and currents:

The load power is the power actually dissipated in the load. If the load is not reactive,
the load power is simply the voltage times the current. If the load is reactive, there
will be phase angle between the voltage and current, and the load power will be equal
to: V * I * cos (phase angle).

In terms of forward and reflected power, the load power is the forward power minus
the reflected power. Generally, the important factor in a process is the load power,
because by definition that is the actual power delivered to the load.

Communication Controls

25-PIN USER PORT

25-Pin User Port Connector

The User port uses a 25-pin, shielded, female, subminiature-D connector. Ground/
return lines are floating and need to be connected as close to the system as possible.

4

Figure 4‑1. User port connector, 25-pin

User Port Cabling Requirements

The cable used to connect the generator’s User port to the system controller must be
a shielded, 25-wire I/O cable. Twisted-pair wiring may be used but is not mandatory.
Signal losses should be minimized by keeping the cable length as short as possible.
The maximum recommended cable length between the generator and the controller is
10 meters (33′). To minimize interference from adjacent electrical equipment, the
EMI shield in the cable must be terminated to the metal shells of the cable’s
connectors. Additionally, the chassis of the generator must be tied to a local earth
ground through an adequately sized copper grounding strap.

Satisfying Minimal Requirements for the 25-Pin User Port

Regardless of whether you are controlling and monitoring the generator through the
User port or through another port, two User port signals must be satisfied for the unit
to be operational: RF PWR ON (pin 4) and INTERLOCK LOOP (pins 10 and 23). In
other words, even if you are controlling the generator through the serial port
interface, the RF signal must be enabled on the User port, and the interlock satisfied.

57020114-00E Communication Controls 4‑1

☞ Important

If you are controlling your generator through a port other than the User port,
make sure that the control mode is set appropriately (to host mode to control
through the Host port, for example). The control mode can be set through an
AE Host command.

Advanced Energy

If you are not using the User port to control or monitor the unit, you can use a
“dummy” or “cheater” plug to satisfy these signals, thereby ignoring the User port.
To make a dummy plug, solder these jumpers on a mating connector.

Jumper Between Pins Description

4 and 13 Connects RF PWR ON pin to +15 V pin

17 and 21 Satisfies RF PWR ON return to ground

10 and 23 Satisfies INTERLOCK LOOP signal

If desired, you can add an emergency off switch in series with the RF PWR ON signal
(pin 4) and/or tie your system interlocks in series with the generator INTERLOCK
LOOP signal (pins 10 and 23).

If the minimum requirements are met and then AC power is applied, RF output will
not automatically be activated. Choose a control mode, and then, to activate RF
output:

• If you are in host control mode, send an RF on command.

• If you are in user control mode, send an RF off signal and then an RF on signal.

Advanced Energy

• Paramount MF 2 kW unit addresses 1 to 31

• Odd parity

• One start bit, eight data bits, one stop bit

• Low-order bytes transmitted before high-order bytes (little endian)

The timeout period for the Paramount MF 2 kW unit is factory set at 0.75 seconds
(that is, no more than 0.75 seconds can elapse between bytes, or the unit will reset
and begin searching for a new message packet). Use command 40 to change this
value.

The host computer must finish one transaction with the Paramount MF 2 kW unit
before it initiates another transaction, either with the same unit or any other unit.

The Paramount MF 2 kW unit sends data through pin 2 (TX RS-232). This pin must
be connected to the receive pin (RX RS-232) on the host computer’s serial connector.
The receive pin is normally pin 2 for a standard, 9-pin serial port.

AE Bus Protocol

The AE Bus protocol uses pure binary data (nothing is coded in ASCII) and is
designed to facilitate direct communications between a host computer and the
Paramount MF 2 kW unit. The AE Bus message packet combines a set quantity of
bits and bytes in such a way that groups of information can be sent over
communications lines at one time. Five types of information (fields) make up a
communications message packet.

• Header (address and the length of data field)

®

Paramount® MF 2 kW Generator

Figure 4‑15. Graphic representation of a message packet

AE BUS HEADER BYTE

The first byte in each packet contains two pieces of information: five bits contain the
packet address, and three bits contain the data byte count. If the message packet
originates with the host computer, the address specifies the packet destination (to the
Paramount MF 2 kW unit, for example). If the packet is going to the host, the address
specifies the packet origin (from the Paramount MF 2 kW unit). The address section
of the header field is five bits long (bits 3 to 7), which allows a total of 32 distinct
addresses. Address 0 (zero) is reserved for the network broadcast address, which the
Paramount MF 2 kW unit does not support.

The remaining three bits (bits 0, 1, and 2) are the length bits. These bits tell the
receiving unit how long the data field is so that the unit can determine when it has
received the entire message. If the data field contains more than six bytes, the value
of these three bits will be set to 7 (07h), and the optional length byte field will
contain a value indicating the number of data bytes in the data field.

☞ Important

The value of these bits refers only to the number of actual data bytes in the
data field. Do not include the checksum byte when calculating the value for
these bits.

57020114-00E Communication Controls 4‑15

AE BUS COMMAND NUMBER BYTE

This 1-byte field contains an 8-bit value from 0 to 255 (00h to ffh) representing the
command number. If the message packet originates with the host computer, this value

Advanced Energy

specifies the purpose of the message packet. If the message originates with the
Paramount MF 2 kW unit, the value specifies the command to which it is responding.

AE BUS OPTIONAL LENGTH BYTE

This field supplements the header field and exists only when the length bits (bits 0, 1,
and 2) in the header field contain a value of 7 (07h). If the number of data bytes in
the data field is ≤ 6, then the three length bits in the header field are sufficient to
represent this amount, 0 to 6 (00h to 06h). Since the data field contains up to 255
bytes of information, the optional length byte is required when the data field is larger
than six bytes.

When the data field is larger than six bytes, the length bits in the header (bits 0, 1,
and 2) equals 7 (07h) and the optional length byte contains a 1-byte value, from 7 to
255 (07h to ffh), representing the number of data bytes in the data field.

AE BUS DATA BYTES

The data field contains 0 to 255 bytes of binary data. This field contains command­related data or a command status response (CSR). Since some commands do not
require data, sometimes the data field is not present.

®

Paramount® MF 2 kW Generator

If the value specified in the length bits (bits 0, 1, and 2) of the header field is 0 to 6,
the Paramount MF 2 kW unit expects 0 to 6 data bytes. However, if the value in the
header field is 7 (07h), the Paramount MF 2 kW unit looks for the optional length
byte after the command field and reads this value to calculate the data byte count.

Unless otherwise specified for individual commands, AE Bus protocol is little
endian, which means that all values greater than 1 byte are sent in little endian order.
For example, a command with 7 data bytes that included one 8-bit value, one 16-bit
value, and one 32-bit value, would be sent as shown in Table 4‑8.

Table 4‑8. AE Bus byte structure

Value to Send Byte Configuration

8-bit value = 15 Byte 1 = 0x0F

16-bit value = 23450 Bytes 2 and 3 = 0x9A 0x5B

32-bit value = 147679 Bytes 4 to 7 = 0xDF 0x40 0x02 0x00

AE BUS CHECKSUM BYTE

This 1-byte field is the last byte in the packet. The value of this byte depends upon
the number of bytes in each of the preceding fields. The transmitting unit determines
this value by accumulating the exclusive-or (XOR) of all bytes of the packet up to,
but not including, the checksum value. The receiving unit accumulates the XOR of
all bytes of the packet, including the checksum. If the result is zero, the unit has
received the packet intact.

Creating an Ideal Communications Transaction

Figure 4‑16 illustrates the steps in an ideal communications transaction between a

host computer and the Paramount MF 2 kW unit.

Figure 4‑16. AE Bus communications transaction

T0: HOST TRANSMITS MESSAGE PACKET

The host computer sends a message packet to the Paramount MF 2 kW unit. The

57020114-00E Communication Controls 4‑17

packet contains one of the following:

T1: UNIT VERIFIES HOST TRANSMISSION PACKET

Once the Paramount MF 2 kW unit receives the host computer transmission message
packet, the Paramount MF 2 kW unit verifies that the message is intended for it and
not for another unit on the network. At this time, the Paramount MF 2 kW unit also
analyzes the checksum to verify that the message was received correctly.

• A command that requests data or status information

• A command and data that change a parameter setting

• An executable command

• If the address does not match, the Paramount MF 2 kW unit does not respond to
the host computer; the Paramount MF 2 kW unit resets and resumes waiting for

Advanced Energy

• If the address matches and the message is intact, the Paramount MF 2 kW unit

If the Paramount MF 2 kW unit receives a request for data or status information, it
gathers and sends the requested information. Otherwise, it evaluates the incoming
command and sends a message packet that contains a 1-byte data value (CSR code)
to the host. The power supply sends CSR code 0 when it has accepted the command.

If the host computer receives a NAK from the Paramount MF 2 kW unit, the host
computer either retransmits the packet or does whatever else it has been programmed
to do in this situation. If the host computer receives an ACK, it waits for the
requested data or status information, or it waits for the CSR code telling it whether or
not the new parameter was accepted. If the host computer receives no response
within a reasonable period, it takes whatever action it has been programmed to take.

®

Paramount® MF 2 kW Generator

a message addressed to it. If the address matches but the exclusive-or (XOR)
sum of the bytes in the packet (including the checksum) is not zero, the
Paramount MF 2 kW unit sends a negative acknowledgment (NAK),
hexadecimal 15h, to the host computer.

sends an acknowledgment (ACK), hexadecimal 06h, to the host computer.

T2: UNIT TRANSMITS RESPONSE TO HOST

The Paramount MF 2 kW unit prepares a response packet with the requested
information or appropriate CSR code, which it then transmits to the host computer.
The host computer then determines, by means of the checksum, if the response
packet is complete. If the host computer detects an error in the transmission (the
checksum is not validated), it can request the packet be sent again by transmitting a
NAK.

T3: HOST ACKNOWLEDGES UNIT RESPONSE

If the Paramount MF 2 kW unit receives an ACK from the host computer, it returns
to the normal waiting state. If the Paramount MF 2 kW unit receives a NAK from the
host computer, the unit retransmits the response packet. The Paramount MF 2 kW
unit continues to retransmit in response to NAK transmissions until the host
computer stops the cycle. If the Paramount MF 2 kW unit receives no response, it
assumes an ACK and returns to the waiting state.

AE HOST COMMANDS

Paramount® MF 2 kW Generator

The following sections describe the command status response (CSR) codes returned
by the Paramount MF 2 kW unit in response to a command, as well as the AE Host
commands for the Paramount MF 2 kW unit.

AE Host Command Status Response (CSR) Codes

When the Paramount MF 2 kW unit receives a command requesting a change in unit
operation (commands 1 through 127), or when the Paramount MF 2 kW unit receives
any command that it rejects (commands 1 through 255), it responds with a command
status response (CSR) code. The CSR is a single-byte number that indicates whether
the unit accepted or rejected the command and, in the case of rejection, the reason the
unit could not respond to the command.

Table 4‑9. AE Host command status response (CSR) codes

Code Meaning

The following CSR codes are sent in response to a command that was not accepted
and provide an indication of why the command was not accepted

99 Command not accepted (there is no such command).

AE Host Command Set

• Commands 1 through 127 request a change to the Paramount MF 2 kW unit,
such as changing a setting in the unit. The unit responds to these commands by
sending a command status response (CSR). This single-byte response indicates
whether the unit has accepted or rejected the command and, in the case of
rejection, the reason the unit could not respond to the command.

• Commands 128 through 255 request information from the unit, such as unit
settings. The unit responds to these commands by sending the data requested if
the command was successful, and a CSR if the command was not successful.

Unless otherwise specified for individual commands, AE Bus protocol is little
endian, which means that all values greater than 1 byte are sent least significant byte
first.

set the setpoint ramping mode and parameters
or set the ramping memory mode.

Ramping Mode and Parameters

In W/s mode, the ramp parameters represent
the ramp rate in watts per second. The
acceptable range for the ramp up and ramp
down parameters in W/s mode is 1 W/s to
65535 W/s.

In timed mode, the ramp parameters represent
the time in ms. The acceptable range for the
ramp up and ramp down parameters in timed
mode is 1 ms to 65535 ms.

The setpoint ramp parameters can be set while
output is on. The ramp parameters are not
allowed to change during a setpoint ramp that
is currently in progress. The setpoint will not
be ramped in either mode if the setpoint
change is less than 1 W.

set communications

watchdog timer

Sets the communications watchdog timer
value in ms. This timer denotes the amount of
time that can pass without a successful
communication. If this timer value is
exceeded, the unit will turn output off if the
output is on.

Each AE Bus communications interface has
its own unique watchdog timer. To set the
watchdog timer value for a given port (for
example, the Host port), send this command
from that port. You can set up any
combination of enable, disable, or time-out
values among the interfaces. A value of 0
disables the watchdog timer.

This parameter is volatile and defaults to 0 ms
each time you turn the unit on. The maximum
value is 65535 ms. The unit stores the
watchdog timer value internally in 10 ms
increments, and truncates any fractional
remainder. The unit accepts a value from 1 to
9, but stores it as a time‑out period of 10 ms.

Set this value with command 118; B0 = 23.

Reports the following parameters:

• Power limit setting for external (DC bias)
regulation mode—When operating in
external (DC bias) regulation mode, the
unit uses an internally set value as a
maximum output power limit. In units
without this feature, this parameter is
hard coded to limit forward power. This
feature allows you to set the power limit
to either forward or delivered power.
This parameter reports whether the unit is
set to use forward or delivered power.

• SOA mode—Reports whether the safe
operating area feature is enabled or
disabled

• Memory mode—Reports whether these
settings are volatile or nonvolatile. When
set to volatile, the settings will default to
factory default settings when power to
the unit is cycled. See the product
specifications for factory default settings.

Installation, Setup, and
Operation

PREPARING TO INSTALL THE UNIT

Spacing and Mounting Requirements

For proper cooling, mount the unit so that there is 13 mm (0.51″) minimum clearance
on the right side of the unit and 102 mm (4″) minimum clearance at the rear. Any
blockages could cause overheating to occur.

For rack installation, ensure that there are supports at the front and the rear of the
unit. Do not use the rack ears to support the weight of the unit.

5

The lifting brackets can be removed before installation if you do not need them. Use
care when removing them as the edges can be sharp.

  DANGER:

RISK OF DEATH OR BODILY INJURY. Disconnect and lockout/tagout all
sources of input power before working on this unit or anything connected to
it.
