Problem
Problem Problem
A phase to ground fault has been
detected between the drive and
motor in this phase.
Excessive current has been
detected between these two
output terminals.
The drive was commanded to
write default values to EEPROM.
The programmed SW Current Trip
(A448) has been exceeded.
A drive rating of 150% for one
minute or 200% for three seconds
has been exceeded.
Failure has been detected in the
drive power section.
The communication network has
faulted.
The RS-485 (DSI) port stopped
communicating.
The checksum read from the board
does not match the checksum
calculated.
Failure has been detected in the
drive control and I/O section.
Solution
Solution Solution
• Check the wiring between the drive
and motor.
• Check the motor for a grounded
phase. Replace the drive if the fault
cannot be cleared.
• Check the motor and drive output
terminal wiring for a shorted condition.
• Replace the drive if the fault cannot be
cleared.
• Clear the fault or cycle power to the
drive.
• Program the drive parameters as
needed.
Check the load requirements and the
SW Current Trip setting (A448).
Reduce the load or extend accel time.
• Cycle power.
• Replace the drive if the fault cannot be
cleared.
• Cycle power.
• Check the communications cabling.
• Check the network adapter setting.
• Check the external network status.
• If the adapter was not intentionally
disconnected, check the wiring to
the port. Replace the wiring, port
expander, adapters, or the complete
drive as required.
• Check the connection.
• Determine if an adapter was
intentionally disconnected.
• Turn off using Comm Loss Action
(C304).
Set the Reset To Defaults parameter
(P112) to option 1 (reset defaults).
• Cycle power.
• Replace the drive if the fault cannot be
cleared.
