SPX ADVANCED APPLICATION MANUAL
SVCH0203—October 2017 www.eaton.com
•
Use absolute encoder
4.
There are too much noise pick-ups in encoder cable
•
Check encoder cable shield and grounding in drive
F44 Device changed (default param.)
Possible cause:
1.
Option board or power unit changed
2.
New device of different type or different rating from the
previous one
Correcting measures:
•
Reset
•
Set the option board parameters again if option board
was changed. Set converter parameters again if power
unit was changed
F45 Device added (default param.)
Possible cause:
1.
Option board of different type added
Correcting measures:
•
Reset
•
Set the option board parameters again
F50 4mA Supervision
Possible cause:
1.
Current at the analog input is below 4mA
2.
Signal source has failed
3.
Control cable is broken or loose
Correcting measures:
•
Check the current loop circuitry
F51 External fault
Possible cause:
1.
Digital input fault
Correcting measures:
•
Remove fault situation from external device
F52 Keypad communication
Possible cause:
1.
The connection between the control keypad or
9000xDrive and the AC drive is broken
Correcting measures:
•
Check keypad connection and possible keypad cable
F53 Fieldbus communication
Possible cause:
1.
The data connection between the fieldbus Master and
the fieldbus board is broken.
Correcting measures:
•
Check installation
F54 Slot fault
Possible cause:
1.
Defective option board or slot
Correcting measures:
•
Check board and slot
F56 Temperature sensor board 1 fault
Temperature protection function is used to measure
temperature and give warning and/or fault when set
limits are exceeded. SPX Advanced application supports
two temperature sensor boards simultaneously. One
can be used for the motor winding and the other for the
motor bearings.
A1 – Temperature limit has been exceeded.
A2 – Sensor not wired or not working.
A3 – Short circuit.
Possible cause:
1.
Temperature limit values set for the temperature board
parameters have been exceeded
Correcting measures:
•
Find the cause of temperature rise
•
Check sensor wiring
F57 Identification
Identification run has failed.
Possible cause:
1.
There was load on the motor shaft when making the
identification run with rotating motor
2.
Motoring or generator side torque/power limits are too
low to achieve a stable run
Correcting measures:
•
Run command was removed before identification
was ready
•
Motor is not connected to the AC drive
•
There is load on the motor shaft
