Otherwise, the dataformat is set to 12/20. It only makes sense to set this bit if the bit “Enh Resol” in parameter [FB0 Identify] is set.Bit 2 “FD Low Baud” – Reduces the communication baud rate from the default setting for the connected encoder with a serial communicationchannel.Bit 3 “SC Quadrant” – Reserved for future use.9 FB0 Loss CfgFeedback 0 Loss ConfigurationConfigures how the drive reacts to an error status condition on the feedback 0device.10 FB0 StsFeedback 0 StatusShows feedback specific errors and alarms for the feedback 0 device.OptionsReservedReservedReservedEncoder AlmReservedUnsupp EncPhase LossQuad LossOpen WireSC AmplitudeSpplyVltRngDiagnosticCommTimeoutMsg ChecksumEncoder ErrDefault 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 0Default:Options:0 = Condition False1 = Condition True3 = “FltCoastStop”0 = “Ignore”1 = “Alarm”2 = “Flt Minor”3 = “FltCoastStop”RW 32-bitIntegerBit 0 “Encoder Err” – When asserted, there is an Encoder Error.Bit 1 “Msg Checksum” – When asserted, the module has experienced a checksum error while attempting to communicate to an encoder via the serialcommunication channel.Bit 2 “Timeout” – When asserted, the module has experienced a time out condition while attempting to communicate to the encoder via the serialcommunication channel.Bit 3 “Comm” – When asserted, there was an error (except Checksum and Time Out) while attempting to communicate to an encoder via the serialcommunication channel.Bit 4 “Diagnostic” – When asserted, the module has experienced a diagnostic test failure on power up.Bit 5 “SpplyVltRng” – When asserted, the voltage source to the encoder is out of range.Bit 6 “SC Amplitude” – When asserted, the module detected that the encoder signal amplitude is out of tolerance.Bit 7 “Open Wire” – When asserted, the module has detected an open wire.Bit 8 “Quad Loss” – Indicates that there is a signal quadrature error.Bit 9 “Phase Loss” – Indicates that an A or B signal of an A Quad B Incremental encoder is disconnected.Bit 10 “Unsupp Enc” – Indicates that the connected encoder is not supported.Bit 12 “Encoder Alm” – When asserted, there is an Encoder Alarm.PowerFlex 750-Series User Manual – Publication 750-UM001C-EN-P – September 2009
