RED LIGHT
Position error too large
The amplitude of the error on the position signal has become too large so
the position signal itself is suspect. The controller cannot operate.
Position problem
A position-sensing problem has occurred, and the motor is still limited in
output because of it.
Position signals are noisy
Electrical noise has been detected within the position-sensing signals. If
severe enough, this can cause limitations to motor output. A red light means
that there has just been a noise event. A constant red light means noise is
continually occurring.
Forced Open Loop
The controller is operating in forced open loop control and is limited in
capability. This can occur because of bad sensor measurements.
CANbus communication
error
The CANbus communication has ceased, and the controller is disabled. This
is the CANbus watchdog error and must be reset via the heartbeat command
through CAN. See the
CANbus Manual
for further details.
IBus CT Fault / ILeg CT Fault
The measurement sensors are untrustworthy, and the system cannot
operate.
Limp Home happening
Indicates that the inverter has detected a condition that causes it to limit
system torque to that specified by the
Limp Home Percentage
Power switches off
Indicates that the inverter has detected a condition that causes it to shut
down the IGBT Switches
YELLOW LIGHT
Disabled
The controller is disabled. It can be disabled by the hardware enable line,
through CANbus, through Key OFF, or through a number of conditions
outlined in the RED LIGHT section of this table.
Fault Occurred
One or more controller modules has faulted, and the fault was cleared. The
controller is limited in operation.
Motoring limited to x%
This caution appears whenever motoring ability has been limited to less than
100%. Besides the conditions outlined throughout this table, motoring can
also be limited by a CANbus command.
Regen limited to x%
This caution appears whenever the motor’s generation ability has been limited
to less than 100%. Besides the conditions outlined throughout this table,
generation can also be limited by a CANbus command.
Power close to or over
limit
Electrical power is close to or over the allowable limit of the motor system. The
controller will experience regeneration limitations.
