6.6 PROGRAMMING HINTS
1.
All control commands should be sent in remote control mode.
2.
An automated control program should initiate control by sending the following command sequence:
<CR>
<- empty line (carriage return) to clear any partially sent previous command
PGM
<- select program mode
LF0
<- turn off line feeds
REM
<- change to remote control
3.
Certain commands are only allowable in certain modes, or may be interpreted by the MTS-1710
differently in different modes. This means that, when programming a sequence, the operation mode,
fault mode, and current mode should be selected first (using the STT/DYN, FMD, and IMD
commands).
Then any special modes and settings, such as synchronizing mode or fault incidence angle, should be
set up. Then, all parameter programming should be done (i.e. voltage, current, phase, frequency
settings). Finally an STR command is given to start a programmed sequence.
4.
A 0.2 second delay should be added before the execution of a STR command to ensure all MTS-1710
internal operations have been completed before entering the FAULT state.
6.7 INDIVIDUAL PHASE AND AMPLITUDE PROGRAMMING
The amplitude and phase of all AC voltage and current outputs can be independently programmed using
“Individual Phase Adjustment Mode” and “Individual Amplitude Adjustment Mode”.
When these two combined modes are set, the MTS-1710 doesn’t use its own intelligence to set fault
currents, voltages and phase angles to simulate standard faults. All settings must be set by the appropriate
RS-232 commands.
