945 At Limit Status
At Limit Status RO 32-bit
Integer
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
Bit 4 “Spd Reg Lmt” – The output of the drive’s speed regulator has reached limit. See P655 [Spd Reg Pos Lmt], P656 [Spd Reg Neg Lmt].
Bit 5 “Freq Hi Lmt” – Scalar control inner ramp high limit is active
Bit 6 “Freq Lo Lmt” – Scalar control inner ramp low limit is active
Bit 7 “FreqOSPosLmt” – Scalar control inner ramp positive (+) overspeed limit is active
Bit 8 “FreqOSNegLmt” – Scalar control inner ramp negative (-) overspeed limit is active
Bit 9 “Flux Braking” – Flux braking is active
Bit 10 “Economize” – Economize is active
Bit 11 “PWM FreqLmt” – PWM frequency is reduced by the thermal regulator
Bit 12 “DB Res Limit” – Dynamic brake thermal protection is active. Verify P385 [DB ExtPulseWatts].
Bit 13 “PsnReg LoLmt” – The position integrator low limit is active
Bit 14 “PsnReg HiLmt” – The position integrator high limit is active
Bit 15 “PsnReg LoSpd” – The position regulator output (speed) is at low limit
Bit 16 “PsnReg HiSpd” – The position regulator output (speed) is at high limit
Bit 17 “TrqCurPosLmt” – The torque current positive limit is active
Bit 18 “TrqCurNegLmt” – The torque current negative limit is active
Bit 19 “FlxCurPosLmt” – The flux current positive limit is active
Bit 20 “FlxCurNegLmt” – The flux current negative limit is active
Bit 21 “Trq Pos Lmt” – The positive torque limit is active. See P670 [Pos Torque Limit].
Bit 22 “Trq Neg Lmt” – The negative torque limit is active. See P671 [Neg Torque Limit].
Bit 23 “Mtrng PwrLmt” – The motoring power limit is active. See P427 [Motor Power Lmt].
Bit 24 “Regen PwrLmt” – The regeneration power limit is active. See P426 [Regen Power Lmt].
Bit 25 “Cur Lmt FV” – The current limit parameter or analog Input current limit is active
Bit 26 “Therm RegLmt” – The thermal regulator torque limit is active
Bit 27 “BusVltgFVLmt” – The bus voltage regulator torque limit is active
Bit 28 “Mtr Vltg Lkg” – The Vds motor voltage limit is active
Bit 29 “TrqPrvPosLmt” – The torque proving positive torque limit is active
Bit 30 “TrqPrvNegLmt” – The torque proving negative torque limit is active
Bit 31 “Cur Rate Lmt” – The Iqs rate limit is active
