Drive Fault Register
The bits in the Drive Fault register indicate the cause of a drive shutdown. The bits in this register are
latched until they are reset by setting the Fault Reset bit (bit 8) of the Drive Control register
(100/1 100). After turning the Fault Reset bit on, the drive may be re-started after turning the com-
mand bits off and then back on again. If the fault conditions still exist, the identifying bit in this regis-
ter will immediately be set again.
The fault conditions reported in this register result in turning off the drive. The UDC task is not
stopped automatically when a drive fault occurs unless it is specifically instructed to in an application
task. The user must ensure that the AutoMax application task tests register 202/1202 and takes ap-
propriate action if a fault occurs.
Note that the status of this register is also reported in the error log for the task in which the error oc-
curred.
