3-74 Programming and ParametersFileGroupNo.NameDescriptionValuesRead-WriteData Type647 Speed Reg KiSpeed Regulator KiSets the integral gain of the speed regulator (in FV motor control modes). Thisvalue is automatically calculated based on the bandwidth setting in P636 [SpeedReg BW], P645 [Speed Reg Kp] and P653 [Spd Loop Damping]. Integral gainmay be manually adjusted by setting P636 [Speed Reg BW] to a value of zero.Integral gain has effective scaling of (per unit torque/sec) / (per unit speed).Units: /SecDefault: 50.00Min/Max: 0.00 / 100000.00RW RealSPEED CONTROLSpeed Regulator648 Alt Speed Reg BWAlternate Speed Regulator BandwidthProvides an independent setting for the same function as P636 [Speed Reg BW],but is active only when Automatic Feedback Loss Switchover occurs (indicated bybit 5 of P936 [Drive Status 2]). A change to this parameter will cause anautomatic update of P649 [Alt Speed Reg Kp], P650 [Alt Speed Reg Ki] and P651[Alt Spd Err Filt BW]. See P636 for additional information regarding speedregulator bandwidth. Also see P635 [Spd Options Ctrl] to enable the Auto TachSwitchover feature.649 Alt Speed Reg KpAlternate Speed Regulator KpProvides an independent setting for the same function as P645 [Speed Reg Kp],but is active only when Automatic Feedback Loss Switchover occurs (indicated bybit 5 of P936 [Drive Status 2]).
