Troubleshooting
Chapter 4
F081
DSI Comm Loss
2
Communications between the drive and
the Modbus or DSI master device have
been interrupted.
• Cycle power.
• Check communications cabling.
• Check Modbus or DSI setting.
• Check Modbus or DSI status.
• Modify using
[Comm Loss
Action].
• Connecting I/O terminals C1 and C2
to ground may improve noise
immunity.
• Replace wiring, Modbus master
device, or control module.
F082
Opt Comm Loss
2
Communications between the drive and
the network option card have been
interrupted.
• Cycle power.
• Reinstall option card in drive.
• Modify using
[Comm Loss
Action].
• Replace wiring, port expander,
option card, or control module.
F083
(1)
EN Comm Loss
2
Internal communications between the
drive and the embedded EtherNet/IP
adapter have been interrupted.
• Cycle power.
• Check EtherNet/IP setting.
• Check drive’s Ethernet settings and
diagnostic parameters.
• Modify using
[Comm Loss
Action].
• Replace wiring, Ethernet switch, or
control module.
F091
(1)
Encoder Loss
2
Requires differential encoder.
One of the 2 encoder channel signals is
missing.
• Check Wiring.
• If
[Speed
Referencex] = 16 “Positioning” and
[Motor Fdbk Type] = 5 “Quad
Check”, swap the Encoder channel
inputs or swap any two motor leads.
• Replace encoder.
F094
Function Loss
2
“Freeze-Fire” (Function Loss) input is
inactive, input to the programmed
terminal is open.
Close input to the terminal and cycle
power.
F100
Parameter Chksum 2
Drive parameter non-volatile storage is
corrupted.
Set
[Reset To Defalts] to 2 “Factory
Rset”.
F101
External Storage
2
External non-volatile storage has failed. Set
[Reset To Defalts] to 2 “Factory
Rset”.
F105
C Connect Err
2
Control module was disconnected while
drive was powered.
Clear fault and verify all parameter
settings. Do not remove or install the
control module while power is applied.
F106
Incompat C-P
2
The PowerFlex 525 control module does
not support power modules with 0.25
HP power rating.
• Change to a different power module.
• Change to a PowerFlex 523 control
module.
F107
Replaced C-P
2
The control module could not recognize
the power module. Hardware failure.
• Change to a different power module.
• Replace control module if changing
power module does not work.
F109
Mismatch C-P
2
The control module was mounted to a
different drive type power module.
Set
[Reset To Defalts] to 3 “Power
Reset”.
F110
Keypad Membrane 2
Keypad membrane failure /
disconnected.
• Cycle power.
• Replace control module if fault
cannot be cleared.
F111
(1)
Safety Hardware
2
Safety input enable hardware
malfunction. One of the safety inputs is
not enabled.
• Check safety input signals. If not
using safety, verify and tighten
jumper for I/O terminals S1, S2 and
S+.
• Replace control module if fault
cannot be cleared.
F114
uC Failure
2
Microprocessor failure.
• Cycle power.
• Replace control module if fault
cannot be cleared.
