Encoder Fault
1. Motor encoder failure.
2. Bad crimps or faulty wiring.
3. See Monitor menu » Motor: Motor
RPM.
ShutdownEMBrake;
Motor
disabled.
Set: Motor encoder
phase failure detected.
Clear: Either cycle KSI,
or if parameter LOS
Upon Encoder Fault=
On and Interlock has
been cycled, then
the Encoder Fault is
cleared and Encoder
LOS fault (code 93)
is set, allowing limited
motor control.
37
Motor Open
1. Motor phase is open.
2. Bad crimps or faulty wiring.

ShutdownMainContactor;
ShutdownEMBrake;
ShutdownThrottle;
FullBrake. Set: Motor phase U, V,
or W detected open.
Clear: Cycle KSI.
38
Main Contactor Welded
(RRDCON & ECON only)
1. Main contactor tips are welded
closed.
ShutdownEMBrake;
Motor
disabled.
Set: Motor encoder
phase failure detected.
Clear: Cycle Power
to KSI
39
Main Contactor Did Not Close
(RRDCON & ECON only)
1. Main contactor did not close.
2. Main contactor tips are oxidized,
burned, or not making good contact.
3. External load on capacitor bank
(B+ connection terminal) that prevents
capacitor bank from charging.
ShutdownMotor;
ShutdownMainContactor;
ShutdownEMBrake;
ShutdownThrottle;
FullBrake.
Set: Just prior to the
main contactor closing,
the capacitor bank
voltage
(B+ connection
terminal) was loaded
for a short time and the
voltage did
not discharge.
Clear: Cycle KSI
Power
46
EEPROM Failure
1. Failure to write to EEPROM
memory. This
can be caused by EEPROM memory
writes
initiated by VCL, by the CAN
bus, by adjusting parameters with the
programmer, or by loading new
software into
the controller. ShutdownMotor;
ShutdownMainContactor;
ShutdownEMBrake;
ShutdownThrottle;
ShutdownInterlock;

ShutdownPD;
FullBrake.
Set: Controller
operating system tried
to write to EEPROM
memory
and failed.
Clear: Download
the correct software
(OS) and matching
parameter default
settings into the
controller and cycle
KSI.
