87 Motor Characterization
Fault
ShutdownMotor;
ShutdownMainContactor;
ShutdownEMBrake;
ShutdownThrottle;
FullBrake; ShutdownPump.
1. Motor characterization failed
during characterization
process. See Monitor
menu » Controller: Motor
Characterization Error for
cause: 0=none 1=encoder
signal seen, but step size
not determined; set Encoder
Step Size manually 2=motor
temp sensor fault 3=motor
temp hot cutback fault
4= controller overtemp
cutback fault 5=controller
undertemp cutback fault
6=undervoltage cutback fault
7=severe overvoltage fault
8=encoder signal not seen, or
one both channels missing
9=motor parameters out of
characterization range.
Set: Motor characterization
failed during the motor
characterization process.
Clear: Correct fault; cycle KSI.
89 Motor Type Fault
ShutdownMotor;
ShutdownMainContactor;
ShutdownEMBrake;
ShutdownThrottle;
FullBrake; ShutdownPump.
1. The Motor_Type parameter
value is out of range.
Set: Motor_Type parameter is
set to an illegal value.
Clear: Set Motor_Type to
correct value and cycle KSI.
91 VCL/OS Mismatch
ShutdownMotor;
ShutdownMainContactor;
ShutdownEMBrake;
ShutdownThrottle;
ShutdownInterlock;
ShutdownDriver1;
ShutdownDriver2;
ShutdownDriver3;
ShutdownDriver4;
ShutdownPD; FullBrake;
ShutdownPump.
1. The VCL software in the
controller does not match the
OS software in the controller.
Set: VCL and OS software do
not match; when KSI cycles,
a check is made to verify that
they match and a fault is
issued when they do not.
Clear: Download the correct
VCL and OS software into the
controller.
92 EM Brake Failed to Set
ShutdownEMBrake;
ShutdownThrottle.
1. Vehicle movement sensed
after the EM Brake has been
commanded to set.
2. EM Brake will not hold the
