APPENDIX E. COMMUNICATIONS
HF-2500A HIGH FREQUENCY WELD CONTROL
990-371
E-13
Command
ALARM error_message
<crlf><lf>
Control State
Any
Description
Identifies the current error condition of operation of the Power Supply. May be in response to
the
ALARM READ
command sent by the host, or may be sent as a result of an error condition
occurring in the Power Supply.
error_message
is a text string describing the error message,
which is the same error message that is displayed to the screen.
Command
CURRENT number_of_data
<crlf>
data <crlf> data <crlf> . . . .
data
<crlf><lf>
Control State
Any
Description
Returns the Current waveform data of the last weld. First field is the number of data to be sent.
Then follows the packets of data. Each data is separated by <crlf> and this command ends with
<crlf><lf>.
number_of_data:
This is the number of data that shall be included in this command. The
Power Supply samples current every 40
µ
s. For a weld less than 80 ms weld time, the
number of data will be approximately:
total weld time
÷
40
µ
s.
This number will
always
be less than 2000.
data:
an integer number in unit of A.
Command
VOLTAGE number_of_data
<crlf>
data <crlf> data <crlf> . . . .
data
<crlf><lf>
Control State
Any
Description
Returns the Voltage waveform data of the last weld. First field is the number of data to be sent.
Then follows the packets of data. Each data is separated by <crlf> and this command ends with
<crlf><lf>.
number_of_data:
This is the number of data that shall be included in this command. The
Power Supply samples Voltage every 40
µ
s. For a weld less than 80 ms weld time, the
number of data will be approximately:
total weld time
÷
40
µ
s.
This number will
always
be less than 2000.
data: A
n integer number in unit of mV.
Command
POWER number_of_data
<crlf>
data <crlf> data <crlf> . . . .
data
<crlf><lf>
Control State
Any
Description
Returns the Power waveform data of the last weld. First field is the number of data to be sent.
Then follows the packets of data. Each data is separated by <crlf> and this command ends with
<crlf><lf>.
number_of_data:
This is the number of data that shall be included in this Command. The
Power Supply samples Current and Voltage every 40
µ
s. For a weld less than 80 ms weld
time, the number of data will be approximately:
total weld time
÷
40
µ
s.
This number will
be always less than 2000.
data: A
n integer number in unit of W.
