MAINTENANCE AND TROUBLESHOOTING
10 Output Over Current
• Insufficient motor inductance
• KIP
or
KII
improperly set causing
excessive output current overshoots.
11
Hall Fault
• Valid only when drive is
set for 6 Step (Hall
feedback) operation.
• Invalid configuration.
• Motor overspeed.
•
Invalid hall state.
• Invalid hall transition.
12 SFD Configuration Error
•
SFD UART error during SFD
initialization.
• Bad motor data check sum.
•
The drive will attempt to initialize the
SFD up to 4 times. If it fails this error
is reported.
13
J3 FB +5V Short
• Excessive current drain on
SFD +5 supply output.
• Excessive loading on SFD +5 supply.
• Short in the feedback cable on SFD
+5 (J3-1) to ground.
14
SFD Motor Data Error
• Motor data in SFD is
outside drive limits or is
inconsistent
•
Motor and Drive are not compatible.
Auto setup calculation yielded a
desired parameter value outside valid
range.
• Incorrect/inconsistent motor data
loaded into the SFD.
15
SFD Sensor Failure Internal
SFD failure.
Excessive electrical noise in the drive
environment causing communications
interference.
16 SFD UART Error Internal SFD failure.
17 SFD Communication Error
•
Feedback cable not connected at the
drive or at the motor.
• Feedback cable shield not connected.
•
Defective feedback cable
• Internal SFD failure.
•
Excessive electrical noise in the drive
environment causing communications
interference.
18
Option Card Watch Dog Time out Communication error between option card
and main board.
