Table 8-8 provides detailed descriptions and solutions for the QuickStick HT safety faults as
identified through the MMI_path_qs_ht_faults_status tag. See the Host Controller Ether-
Net/IP Communication Protocol User Manual, MMI-UM004, for a complete description of
all faults and their resolution.
In the QuickStick HT motor error descriptions that are provided in Table 8-8, the Motor Sus-
pend Fault field shows when motion on the motor is suspended. Motion cannot resume until
the fault is cleared. Vehicles are not allowed to enter the section of the Path where the motor is
located while the motor is suspended.
