Automatically cleared in the homing routineor due to clearing of encoder faults.Bit 9 “Inv Home In” – State of the corresponding bit in the [Enc 1 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 [Enc 1 Cfg] parameter.16 Enc 1 Error StsEncoder 1 Error StatusStatus information that will result in a feedback loss condition for Encoder 1.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.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 [Enc 1 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 [Enc1 Cfg]).Bit 15 “SI Comm Loss” – Indicates a communication loss between the main control board and the encoder module over the Serial Interfacebackplane.17 Enc 1 PhsLss CntEncoder 1 Phase Loss CountDisplays the active value of the encoder module's Encoder 1 phase loss counterhardware register. Values in this register accumulated over 8 msec are used todetect Phase Loss errors.18 Enc 1 QuadLssCntEncoder 1 Quad Loss CountDisplays the active value of the encoder module's Encoder 1 quad loss counterhardware register.
