The FREQ modifier may also be used to instruct the power source to measure the output frequency as follows. Note
that the noun modifier precedes the channel indicator:
FNC ACS FREQ :CH00 <CR><LF>
Followed by string:
FTH FREQ <CR> <LF>
The response from the power source when the frequency is 380.0 Hz is then:
<SP> 380.0 <CR> <LF>
3.8.4.3 PANG
The PANG (phase angle) noun modifier may be contained in a string as an instruction to the power source with SET,
SRX or SRN. Depending on the OP-code, an output phase angle (or phase angles) may be programmed or the upper
or lower limit set in one-tenth degree increments. The channel indicator which precedes the modifier determines which
phase (or phases) will be so set. The number which follows the modifier in the string determines the phase angle to be
programmed.
FNC ACS :CH02 SET PANG90 <CR> <LF>
As with the FREQ and VOLT modifiers, the INX OP-code may be used to request time for PANG measurement:
FNC ASC PANG :CH02 <CR><LF>
INX PANG :CH01 <CR> <LF>)
When addressed to talk, the power source responds with the maximum time required to make the measurement in
seconds:
<SP> 5 <CR> <LF>
When operating in the external sync mode, the phase angle of phase A relative to the external sync input may be
programmed as follows:
FNC ASC :CH01 SET PANG90 SET SYNI <CR><LF>
The phase A output will still track the SYNC input, but will be offset by 90 degrees. The phase angles of phases B and
C will still be relative to phase A.
3.8.4.4 CURL
The CURL (current limit) noun modifier may be contained in a string as an instruction to the power source with SET,
SRX or SRN. Depending on the OP-code, an output current limit (or limits) may be programmed or set as to upper or
lower limit in or 0.01 ampere increments up to the power source maximum current. The channel indicator which
precedes the modifier determines which phase (or phases) will be so set. The number which follows the modifier in the
string determines the current limit to be programmed.
FNC ACS :CH00 SET CURL 2.5 <CR> <LF>
3.8.4.5 SYNI
SET SYNI enables the external SYNC input. The power source returns to the internal sync mode in the absence of the
SYNI noun modifier from any set-up string. Any channel indicator may be used in the set-up string that includes SYNI.
