No. Name Type Description
46 X stop Trip
The X stop trip fault occurs when the X stop circuit is open and when X stop is
configured as a trip fault. X stop is configured as a trip fault when parameter X
stop mode is set equal to Trip flt stop. Any other setting for parameter X stop
mode disables the X stop trip fault.
The state of the X stop circuit is determined by the value of the variable to
which parameter X stop request sel points. The X stop trip fault can be
disabled, along with all other X stop behavior, by setting parameter X stop
request sel equal to Unused.

Run req & xstop
open
Trip
The Run req & xstop open trip fault occurs when the X stop circuit is open, the
drive is stopped, and one of the following requests is issued: Run request, Jog
request, or Full flux request.
The state of the X stop circuit is determined by the value of the variable to
which parameter X stop request sel points. The trip fault can be disabled,
along with all other X stop behavior, by setting parameter X stop request sel
equal to Unused.

48 BICM card temp
low
Trip The BICM card temp low trip fault occurs when the sensor on BICM measures
a temperature that is –20C or below.
BIC ambient temp is the variable being monitored to generate this fault.
Primary causes:
Failed thermal sensor on BICM.
Ambient temperature is too low.
Possible board failures:
BICM
49 HtSink DB temp
low
Trip The HtSink DB temp low trip fault occurs when the dynamic brake heatsink
temperature (variable DB heat sink temp) is too low.
The main purpose of this trip fault is to detect the absence of the thermal
sensor input from the heatsink.
Primary causes:
The DB heatsink thermal sensor input is not present.
No power to TFBA card or TFBA card failure.
Possible board failures:
BICM
TFBA
CPFP
Possible wiring faults:
Thermal sensor input to TFBA is missing or damaged.
