Description
Action Required
≡
Watchdog Fault
Generally occurs due to an
unforeseen circumstance. The drive
is inoperable until power is cycled.
Contact technical support.
-1
Not Configured
Drive configuration required.
Set drive parameters and execute
CONFIG.
A4
CAN Supply Fault
A problem with the internal voltage
supply for the CANbus.
The drive probably needs repair.
Contact technical support.
b
Drive Locked
Security code and key do not match.
Fatal fault; drive cannot be
operated.
Contact technical support.
e
Parameter Memory
Checksum Failure
The non-volatile memory used to
store drive parameters is empty or
the data is corrupted.
Reconfigure the drive, or download the
parameter set, and save the
parameters.
E
Failure Writing to
Flash Memory
An internal problem accessing the
flash memory. Fatal fault; drive
cannot be operated.
Contact technical support.
e101
FPGA Config Fail
The code for the FPGA did not load.
Fatal fault; drive cannot be
operated.
Contact technical support.
e105
Self Test Fail
The power-up self test failed. Fatal
fault; drive cannot be operated.
Contact technical support.
e106
Digital EEPROM
Fault
A problem accessing the EEPROM on
the digital board. Fatal fault; drive
cannot be operated.
Contact technical support.
e107
Power EEPROM
Fault
A problem accessing the EEPROM on
the power board. Fatal fault; drive
cannot be operated.
Contact technical support.
e108
Vbus Measure
Circuit Fail
A failure occurred in the circuit that
measures bus voltage.
Reset faults. If the fault persists, the
drive probably needs repair. Contact
technical support.
e109
Current-Sensors
Offset Out-of-
Range
The calculated offsets for the current
sensors are out of range.
Reset faults. If the fault persists, the
drive probably needs repair. Contact
technical support.
F
Foldback
(Note: F is lit steadily. This is a
warning, not a fault.)
Drive average current exceeds rated
drive continuous current.
Check the drive-motor sizing. This
warning can occur if the drive is
under-sized (under-powered) for the
application.
F1
Drive Foldback
Drive average current exceeds rated
drive continuous current. This is a
fault; it occurs after the Foldback
warning has occurred.
Check motor-drive sizing.
F2
Motor Foldback
Motor average current exceeds rate
motor continuous current. This is a
fault.
Check the drive-motor sizing. This
warning can occur if the motor is
under-sized (under-powered) for the
application.
H
Motor Over-
Temperature
Either the motor has overheated, or
the drive is not set up correctly for
the motor temperature sensor.
Check that the drive is configured
properly (using THERMODE,
THERMTYPE, THERMTHRESH and
THERMTIME), and that the motor
temperature sensor is properly
connected to the drive if needed.
If the drive is configured and wired
properly, check whether the motor is
under-sized for the application.
