SynqNet Network/Node Faults Diagram

MPIMotorFaultBitAMP_FAULT External amp fault input pin. Indicates a fault condition in the amplifier.
MPIMotorFaultBitDRIVE_FAULT Bit in the drive interface status register. Indicates a fault condition in the drive.
MPIMotorFaultBitWATCHDOG_FAULT Bit in the drive interface status register. Indicates a drive failure due to a watchdog timeout. The node alternately sets/clears the watchdog each sample, the drive's processor then clears/sets the watchdog. If the drive's processor does not respond, the watchdog fault bit is set.
MPIMotorFaultBitCHECKSUM_ERROR Bit in the drive interface status register. Indicates the data transfer (via serial or parallel memory interface) between the failed SynqNet node FPGA and drive with a checksum error.
MPIMotorFaultBitFEEDBACK_FAULT Bit in the drive interface status register. Active when one or more of the feedback status bits is triggered. Indicates that the drive/motor position feedback system has failed.
MPIMotorFaultBitAMP_NOT_POWERED

Bit in the drive interface status register. The SynqNet drive amplifier power stage does not have sufficient voltage. The motor windings cannot be energized properly until this bit is clear.

MPIMotorFaultBitDRIVE_NOT_READY

Bit in the drive interface status register. The SynqNet drive is not ready to receive commands or servo motors. This fault indicates the drive has not completed its processor initialization or there is some other serious drive processor problem.
