5.3.25 "MTUNE" Command (Automatic Tuning Procedure)
The 'MTUNE\r' command is used in order to launch the automatic load
recognition procedure on the LiAM power supply. It is strongly suggested to run this
procedure the first time a new load is connected to the power unit so that internal
parameters are optimized for working with that specific load (e.g. automatic rail
switching and some other controls).
In order to run the automatic load recognition process, the following
command must be fed to the power unit:
The LiAM power supply replies with an acknowledgment '#AK\r' command
if the procedure is correctly launched. Please note that during the automatic tuning
process, lasting for about 13 seconds, the communication is suspended and the power
supply Ethernet socket ignores all received commands.
At the end of this procedure, if successful, the power supply stores the value of
the estimated resistive part of the load in its internal non-volatile memory.
The LiAM power units reply with a non-acknowledgment '#NAK\r' command
when:
the output is enabled;
the power supply has experienced a fault.
Please note that in order to make the computed R
module operation, a 'MUP\r' command needs to be sent to the power supply unit at
the end of the procedure.
