Status of dynamic conditions within the drive that are either active or a limit is being applied.
Bit 0 “Current Lmt” – Scalar current limit is adjusting the output frequency
Bit 1 “Bus Vltg Lmt” – Scalar bus voltage limit is adjusting the output frequency
Bit 2 “MaxSpeed Lmt” – Motor speed reference is limited to maximum forward speed or maximum reverse speed. See P520 [Max Fwd Speed], P521 [Max Rev
Speed].
Bit 3 “OverSpd Lmt” – Motor speed reference positive (+) trim is at maximum speed limit plus or minus (+/-) the overspeed limit
