F041 Phase UV Short • Check the motor and drive output terminal wiring for a shorted condition.
• Replace drive if fault cannot be cleared.
F042 Phase UW Short
F043 Phase VW Short
F048 Params Defaulted • Clear the fault or cycle power to the drive.
• Program the drive parameters as needed.
F059 (1) Safety Open Check safety input signals. If not using safety, verify and tighten jumper for I/O terminals S1, S2 and S+.
F063 SW OverCurrent • Verify connections between motor and load.
• Verify level and time requirements.
F064 Drive Overload Reduce load or extend Accel Time.
F070 Power Unit • Check maximum ambient temperature has not been exceeded.

• Replace wiring, Ethernet switch, or control module.
F091
(1)
Encoder Loss • Check Wiring.
• If P047, P049, P051 [Speed Referencex] = 16 “Positioning” and A535 [Motor Fdbk Type] = 5 “Quad Check”, swap the Encoder channel inputs or
swap any two motor leads.
• Replace encoder.
F094 Function Loss Close input to the terminal and cycle power.
F100 Parameter Chksum Set P053 [Reset To Defalts] to 2 “Factory Rset”.
F101 External Storage Set P053 [Reset To Defalts] to 2 “Factory Rset”.
F105 C Connect Err Clear fault and verify all parameter settings. Do not remove or install the control module while power is applied.
F106 Incompat C-P • Change to a different power module.
• Change to a PowerFlex 523 control module.
F107 Replaced C-P • Change to a different power module.
• Replace control module if changing power module does not work.
No. Fault Action
