When the positionregulator is not active, this parameter is initialized to P836 [Psn Actual].724 Psn Reg StatusPosition Regulator StatusIndicates status of position control logic.ValuesDefault: 0Min/Max: –2147483648 / 2147483647Read-WriteData TypeRO32-bitIntegerOptionsReservedReservedReservedReservedInPsn DetectPsnW2Detect (1)PsnW1Detect (1)Intgrtr HoldPsn Reg ActvSpd Lmt HiSpd Lmt LoInteg Lmt HiInteg Lmt LoPsn IntgrtrOffset ReRefOffsetIntgtrDefault 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0Bit 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0(1) 755 drives only.0 = False1 = TruePOSITION CONTROLPosition Cfg/StsBit 0 “OffsetIntgtr” – Indicates the position offset Integrator is active with the position offset integrator bit P721 [Position Control] Bit 3 “OffsetVel En” ison.Bit 1 “Offset ReRef” – Indicates the position offset re-referencing is active with the position offset re-referencing bit P721 [Position Control] Bit 2“Offset ReRef” is on.Bit 2 “Psn Intgrtr” – Indicates the position integrator is active with the position integrator bit P721 [Position Control] Bit 1 “Intgrtr En” is on.Bit 3 “Integ Lmt Lo” – Indicates the position integrator is at the low limit.Bit 4 “Integ Lmt Hi” – Indicates the position integrator is at the high limit.Bit 5 “Spd Lmt Lo” – Indicates the position regulator output (speed) is at the low limit.Bit 6 “Spd Lmt Hi” – Indicates the position regulator output (speed) is at the high limit.Bit 7 “Psn Reg Actv” – Indicates the position regulator is activeBit 8 “Intgrtr Hold” – Indicates the position Integrator is held in present stateBit 9 “PsnW1Detect” – Indicates the position watch 1 has detected motor position equal to its setpoint, from the proper direction.Bit 10 “PsnW2Detect” – Indicates the position watch 2 has detected motor position equal to its setpoint, from the proper direction.Bit 11 “InPsn Detect” – Indicates P835 [Psn Error] is within the position band specified by the in-position band P726 [In Pos Psn Band]725 Zero PositionZero PositionSets the absolute user zero position. When the zero position bit P721 [PositionControl] Bit 4 “Zero Psn” is set, P836 [Psn Actual] accumulates the value of P847[Psn Fdbk] - the P725 [Zero Position], and P836 [Psn Actual] becomes zero whenP847 [Psn Fdbk] is at the zero position. The homing function also sets the valueafter homing process is completed.726 In Pos Psn BandIn Positive Position BandwidthSets the overall bandwidth of the in position detector. The detector sets thein-position detect bit P724 [Psn Reg Status] Bit 11 “InPsn Detect” when P835[Psn Error] is within this position band for a sufficient time specified by thein-position dwell time P727 [In Pos Psn Dwell]. A modest hysteresis count isadded to the position bandwidth after the position error is within specified limits.727 In Pos Psn DwellIn Positive Position DwellSets dwell time for the in position detector. Position error must be within the valuespecified by the in-position band P726 [In Pos Psn Band] for this amount of timebefore the in-position detector sets the in-position detect bit P724 [Psn RegStatus] Bit 11 “InPsn Detect”. A momentary out-of-position indication will resetthe internal timer and clear the in-position detect bit P724 [Psn Reg Status] Bit 11“InPsn Detect”.Default: 0Min/Max: –2147483648 / 214748364700 / 2147483647Default: 0.0040Min/Max: 0.0001 / 10.0000RW 32-bitIntegerRW 32-bitIntegerRW RealPowerFlex 750-Series User Manual – Publication 750-UM001C-EN-P – September 2009
