It selectsbetween speed regulation, torque regulation, or position regulation operation ofthe drive. The source of P685 [Selected Trq Ref] will be determined by theselection in this parameter when P181 [DI SpTqPs Sel 0] and P182 [DI SpTqPsSel 1] have selected “Disabled” or selected bits that are logic low.In P935 [Drive Status 1] three bits are provided that indicate the regulation modeof the drive when it is running. Bit 21 “Speed Mode” will become set when thedrive is running with the speed regulator active. Similarly, Bit 22 “PositionMode”and Bit 23 “Torque Mode” indicate when their respective regulation modes areactive.Under some conditions, the active torque mode may be forced into speed moderegardless of the setting of Speed/Torque/Position. The P313 [Actv SpTqPsMode] parameter will indicate this and will reflect the mode selection that is inuse.Possible selections for Speed/Torque/Position are:“Zero Torque” (0) – Drive operates as a torque regulator with P685 [Selected TrqRef] forced to a constant value of zero torque.“Speed Reg” (1) – Drive operates as a speed regulator. P685 [Selected Trq Ref]comes from P660 [SReg Output] plus P699 [Inertia Comp Out].“Torq Ref” (2) – Drive operates as a torque regulator. P685 [Selected Trq Ref]comes from P4 [Commanded Trq]. Under some conditions such as jogging orperforming a ramp to stop operation, the drive will automatically bypass thisselection and temporarily switch to speed regulation mode.“SLAT Min” (3) – Drive operates in “Speed Limited Adjustable Torque – Minimumselect” mode. This is a special mode of operation used primarily in winderapplications. The drive will typically operate as a torque regulator, provided thatthe P4 [Commanded Trq] value is algebraically smaller in value than the speedregulator’s output. The drive may automatically enter speed regulation mode,based on conditions within the speed regulator and the magnitude of the speedregulator’s output relative to the torque reference.“SLAT Max” (4) – Drive operates in “Speed Limited Adjustable Torque –Maximum select” mode. This is a special mode of operation used primarily inwinder applications. The drive will typically operate as a torque regulator,provided that the P4 [Commanded Trq] value is algebraically larger in value thanthe speed regulator’s output. The drive may automatically enter speed regulationmode, based on conditions within the speed regulator and the magnitude of thespeed regulator’s output relative to the torque reference.“Sum” (5) – Drive operates as a speed regulator. P685 [Selected Trq Ref] comesfrom P660 [SReg Output] plus torque adders summed with P4 [Commanded Trq].“Profilier” (6) – Drive uses the Speed Profiler / Position Indexer function. The driveoperates as either a speed or position regulator. Mode of operation will dependon the configuration of the Step Types in the Profiler / Indexer table.“Psn PTP” (7) – Drive operates as a position regulator. P685 [Selected Trq Ref]has the same source as in Sum mode. The position control is active inPoint-to-Point mode and uses its Point-to-point position reference.“Psn Camming” (8) – Drive operates as a position regulator. P685 [Selected TrqRef] has the same source as in Sum mode. The position control is active inPosition CAM mode and uses its PCAM Planner position and speed reference.“Psn PLL” (9) – Drive operates as a position regulator. P685 [Selected Trq Ref]has the same source as in Sum mode. The position control is active in PositionPhase Lock Loop mode and uses its PLL Planner position and speed reference.“Psn Direct” (10) – Drive operates as a position regulator. P685 [Selected TrqRef] has the same source as in Sum mode. The position control is active in Directmode and uses its Direct Position Reference.1 = “Speed Reg”0 = “Zero Torque”1 = “Speed Reg”2 = “Torque Reg”3 = “SLAT Min”4 = “SLAT Max”5 = “Sum”6 = “Profilier” 7557 = “Psn PTP”8 = “Psn Camming”9 = “Psn PLL”10 = “Psn Direct”755755Read-WriteData TypeRW 32-bitIntegerPowerFlex 750-Series User Manual – Publication 750-UM001C-EN-P – September 2009
