5 FeedbackNoiseFault Sets when simultaneous
transitions of feedback of A and B
are detected by the servo module.
6 AuxFeedbackFault Sets when the differential
electrical signal for one or more of
the feedback channels are at same
level or loss of feedback power or
common electrical connection
between servo module or drive
and the auxiliary feedback device.
7 AuxFeedbackNoiseFault Sets when simultaneous
transitions of feedback of A and B
are detected by the servo module.
8-12 Reserved
13 GroundShortFault Sets when the drive detects an
imbalance in the DC bus supply
current – indicating that current is
flowing through an improper
ground connection.
14 DriveHardFault Set when the drive detects a
serious hardware fault.
15 OverspeedFault Sets when the speed of the axis
exceeds the overspeed limit which
is typically set to 150% of
configured velocity limit for the
motor.
16 OverloadFault Sets if the load limit for the
motor/drive persists after the
Overload warning bit has been set.
17 DriveOvertempFault Sets when the drive’s temperature
exceeds the drive shutdown
temperature.
18 MotorOvertempFault Sets when the motor’s
temperature exceeds the motor
shutdown temperature.
19 DriveCoolingFault Sets when the ambient
temperature surrounding the
drive’s control circuitry exceeds
the ambient shutdown
temperature.
20 DriveControlVoltageFault Sets when the power supply
voltages fall outside of acceptable
limits.
21 FeedbackFault Sets when one of the feedback
sources has a problem that
prevents the drive from receiving
accurate or reliable position
information from the feedback
device.
