15.3 Alarms in selfcheck ROUTINES
Following alarms occur only when the response of a selfchecking routine
(SELFCHECK#1 or SEKFCHECK#2) at the end of the data collection, reports a
problem in a component of the steering system (see 14 – TROUBLESHOOTING
STRUCTURE).
SELFCHECK#1 checks motor and controller (three phase power bridge).
SELFCHECK#2 checks encoder and mechanics (transmission, gears, ball
bearings).
1) SELFCHECK #1
Warning 0xFE00=205 [M,S]:
- Cause: This warning occurs when the SELFCHECKING routine #1 is in
progress and the check result has not been determined yet.
This selfchecking routine carries out a voltammeter measure of
the motor resistances between phase V and W (Rvw) and
between phase W and U (Rwu) by injecting a fixed 14.7Adc
current . The goal of this selftest is to check the functionality of
motor and three phase power bridge. After the gathered data
have been processed and an unexpected result occurred, this
warning message will turn in an alarm information (see below).
- Remedy: recycle the key to exit the SELFCHECK #1 warning
2) CHECK #1 OK
Warning 0xFE0F=205 [M] :
- Cause: This alarm occurs only as a response of the SELFCHECK #1. It
occurs in case the selfcheck #1 has passed. Condition for
