Irb6400 m99 cold boot woes

    Hi, i have just started to commission 4 irb6400 m99 units, all had been standing and had errors. I have cold booted 3 so far, one has been successful but the other 2 error 39111 wrong type found dc-link dsqc 345d found dsqc 345e expected .i assume however they were working before, anyone know the difference between 345d and e?

    Many thanks in advance

    Is this an IRB6400R which uses the DC4 (DSQC345E) or is it an IRB6400PE which uses the DC3 (DSQC345D)?
    The DC3 rectifier uses a higher 3-ph input voltage at 430VAC. It's found in 6400PE, 640, 840, and custom gantry systems.
    The DC4 rectifier uses the more common 3-ph 262VAC input that was standard since the IRB6000.
