What is the reason for AL560 on Lexium 26 drive
AL560 is an indication that there is a problem with the AC logic power.
AC logic means AC loss of control stage (L1 and L2). Since it takes ~150ms between AC loss detection and till DSP is “dead” drive triggers this fault should allow controller enough time to safely stop the system.
Condition for this fault detection:
Read AC LOSS indication from power board
Ignore the first indication (filter)
