WARNING/ALARM 10
MOTOR TIME
According to the electronic thermal protection, the motor is overheated.
Parameter 117,
Motor Thermal Protection,
allows a choice of whether
the drive is to give a warning or an alarm when the
Motor Thermal
Projection
reaches 100%. The fault is that the motor is overloaded to
more than 100% of the preset rated motor current for too long. Check
that the motor parameters 102 through 106 have been set correctly.
WARNING/ALARM 11
MOTOR THERMISTOR
The thermistor or the thermistor connection has been disconnected.
Parameter 117,
Motor Thermal Protection,
allows a choice of whether
the drive is to give a warning or an alarm. Check that the thermistor
has been correctly connected between terminal 53 or 54 (analog
voltage input) and terminal 50 (+10 V supply).
WARNING/ALARM 12
CURRENT LIMIT
The current is higher than the value in parameter 215,
Current Limit
,
and the drive trips after the time set in parameter 412,
Trip Delay
Overcurrent,
has passed. Run AMA on a cold motor in parameter 107,
Automatic Motor Adaptation
.
WARNING/ALARM 13
OVER CURRENT
The inverter peak current limit, approximately 200% of the rated
current, has been exceeded. The warning will last approximately 1 or
2 seconds, and then the drive will trip and signal an alarm.
Turn off the drive and check for free rotation of the motor shaft and
other causes of the overload. Run AMA on a cold motor in parameter
107,
Automatic Motor Adaptation
.
ALARM 14
EARTH FAULT
There is current leakage from the output phases to ground, either in the
leads between the drive and the motor or in the motor itself.
Remove power to the drive and correct the ground fault.
ALARM 15
SWITCH MODE FAULT
Fault in the switch mode power supply (internal ±15 V supply).
Contact the Trane service department.
ALARM 16
CURR. SHORT CIRCUIT
There is a short circuit in the output from the drive.
Remove power to the drive and correct the short circuit.
WARNING/ALARM 17
STD BUSTIMEOUT
There is no serial communication with the drive.
This warning will only be enabled if parameter 510,
Bus Time Interval
Function,
has been set to a value different from OFF.
If parameter 510,
Bus Time Interval Function,
has been set to
Stop
and Trip
[5], the drive will first give off an alarm, then ramp down and
finally trip while giving an alarm. It is possible to increase parameter
509,
Bus Time Interval
.
WARNING/ALARM 18
HPFB TIMEOUT
There is no serial communication with the communication option card in
the drive.
The warning will only be enabled if parameter 804,
Bus Time Interval
Function,
has been set to anything but OFF. If parameter 804,
Bus
Time Interval Function,
has been set to
Stop and Trip,
the drive will
first give an alarm, then ramp down and finally trip while giving an
alarm.
Parameter 803,
Bus Time Interval
could possibly be increased.
Parameter 803 is only available when a communication option card is
installed in the drive.
WARNING 19
EE ERROR POWER
There is a fault on the power card EEPROM. The drive will continue to
function, but is likely to fail at the next power-up. Contact the Trane
service department.
WARNING 20
EE ERROR CONTROL
There is a fault in the EEPROM on the control card. The drive will
continue to function, but is likely to fail at the next power-up. Contact the
Trane service department.
