Danaher Motion 05/2008 Basic ConfigurationS200-VTS Product Manual 737.4 Configuring with SFD Feedback7.4.1 SFD Motor ParametersWhen the drive is powered up and connected to a motor with SFD feedback, the drive willautomatically configure itself for the attached motor by loading the default motor parameters.The default motor parameters provide robust performance of current and velocity loops withoptimized settings to protect the motor from thermal overload. For most applications, thesedefault motor parameter settings are recommended because they provide excellentperformance and require no additional tuning. To use the default motor parameters verify thatSelSFDParam is set to SFD, which is the factory default setting.If the response time and/or stability of the system needs to be further optimized for the specificapplication, the motor parameters will need to be modified. To modify the motor parameters, setSelSFDParam to Drive. This setting unlocks the motor parameters and allows the parametersto be individually set with the S200Tools utility. The modified motor parameters will need to besaved to the drive’s non-volatile memory (click the NV Save button) to ensure that the changedsettings are loaded when the drive is powered up.CAUTIONIncorrect motor parameter settings can cause damage to the motor and/or drive.The motor parameters need to be set correctly to match the drive to the motor. Thecorrect parameter settings ensure:The drive is matched to the motor inductance and pole count.The current and velocity loops are stable with good bandwidth.The motor is protected from thermal overload.NOTEA good starting point to setting the motor parameters is to obtain the default motorparameters and then edit only the parameters that need to be changedUsing the S200 Tools, set SelSFDParam to SFD, this loads the default motorparameters.Next, set SelSFDParam to DRIVE. This will allow the motor parameters to beedited. Change only the parameters you are looking to optimize.When finished setting the motor parameters (and any other parameters),save the parameters to NV Memory by clicking the NV Save button.The following drive setup parameters controlled by SelSFDParam:Parameter ValueKVP Velocity loop proportional gain.KIP Current loop proportional gain.DPoles Drive pole pairs.I2TF0 Speed of response for motor transient thermal protection.I2TTrip Fault trip level for motor transient thermal protection.IlmtPlus,IlmtMinusClamps drive maximum Iout based on motor Ipeak.
