Automatically cleared in the homing routineor due to clearing of encoder faults.Bit 9 “Inv Home In” – State of the corresponding bit in the [Encoder Cfg] parameter. When set, the home input signal will be inverted.Bit 10 “Home Input” – Active state of the Home Input signal. This status bit gets inverted if the “Inv Home In” bit is enabled.Bit 11 “HomeIn Armed” – Indicates that the homing logic is configured to latch the encoder position upon the next transition of the home input.Bit 12 “HomeIn Event” – Indicates that the homing logic has latched the encoder position in response to a transition of the home input.Bit 13 “HomMrk Armed” – Indicates that the homing logic is configured to latch the encoder position upon the next marker (Z channel) pulse.Bit 14 “HomMrk Event” – Indicates that the homing logic has latched the encoder position in response to a marker (Z channel) pulse.Bit 15 “Direction” – State of the corresponding bit in the [Encoder Cfg] parameter.6 Error StatusError StatusStatus information that will result in a feedback loss condition.OptionsSI Comm LossReservedReservedReservedReservedReservedReservedReservedReservedReservedReservedReservedReservedQuad LossPhase LossOpen WireDefault 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 00 = Condition False1 = Condition TrueBit 0 “Open Wire” – Indicates that an input signal (A, B or Z) is in the same state as its complement (A Not, B Not, Z Not). For open wire detection towork, the encoder signals must be differential (not single ended). The Z channel is only checked when enabled. -- see [Encoder Cfg].Bit 1 “Phase Loss” – Indicates that more than 30 phase loss (open wire) events have occurred over an 8msec time period. The same restrictionsapply as on [Encoder Cfg] Bit 0.Bit 2 “Quad Loss” – Quadrature loss events occur when simultaneous edge transitions occur on both the A and B encoder channels. Indicates thatmore than 10 quad loss events over a 10 msec time period are detected. Only valid when both A and B channels are used (not 'A Chan Only' in[Encoder Cfg]).Bit 15 “SI Comm Loss” – Indicates a communication loss between the main control board and the encoder module over the Serial Interfacebackplane.7 Phase Loss CountPhase Loss CountDisplays the active value of the encoder module's phase loss counter hardwareregister. Values in this register accumulated over 8 msec are used to detectPhase Loss errors.8 Quad Loss CountDisplays the active value of the encoder module's quad loss counter hardwareregister. Values in this register accumulated over 8 msec are used to detect QuadLoss errors.Default: 0Min/Max: 0 / 127Default: 0Min/Max: 0 / 15RORORealRealPowerFlex 750-Series User Manual – Publication 750-UM001C-EN-P – September 2009
