Advanced Parallel System Identification (*Idn?); Advanced Parallel Memory Settings - TDK-Lambda G+1U 5kW User Manual

Advanced Parallel System Error Description
Slave unit communication error during operation
Last Slave unit is missing or not connected
Advanced Parallel system is waiting for slave unit to become ready (@start-up)
Unrecoverable Advanced Parallel system error
Paralleled units are not identical (non-matching Voltage and/or Current rating)
Paralleled power supplies equipped with a Power Sink module, along with
standard power supplies (without a Power Sink module), which have firmware
revision below 02.112.
Table 5-2: Advanced Parallel Errors and Display Notifications
Advanced Parallel system error status can be detected by the questionable group registers. Refer
to Section 6.3.2 Questionable Group (Fault Register) Structure.

Advanced Parallel system identification (*idn?)

To identify a system connected in parallel, master unit updates its identification name. Standard
unit identification string format is: TDK-LAMBDA,Gx-y,S/N,G:r.
• x – rated voltage, y – rated current, S/N – serial number, r – firmware revision.
Parallel system identification string format: TDK-LAMBDA,GSx-z,S/N,G:r.
• z – total advanced parallel system current.
The "S" letter, following the "G" letter, identifies advanced parallel system.
The total current of the system is updated, identifying the total current. The serial number of the
master unit is preserved.
In case of a Blank Panel Option power supply, the additional paralleling system 'S' letter is added
following the 'B' letter, i.e., TDK-LAMBDA,GBSx-z,S/N,G:r.

Advanced Parallel memory settings

Power supplies change role when assembled (or disassembled) into (from) an Advanced Parallel
System. Three roles are available:
Single – No Slave or Master units are connected.
Master – At least one Slave unit is connected.
Slave – A unit (or multiple units) connected to a Master unit.
Before assembling an Advanced Parallel System, each units' role is Single.
Memory settings tables are the settings of the power supply immediately following role change.
These settings can be modified by the user in Single or Master roles only. Slave role settings can't
be modified.
