Description
Communications between the drive and
the Modbus or DSI master device have
been interrupted.
Communications between the drive and
the network option card have been
interrupted.
Internal communications between the
drive and the embedded EtherNet/IP
adapter have been interrupted.
Requires differential encoder.
One of the 2 encoder channel signals is
missing.
"Freeze-Fire" (Function Loss) input is
inactive, input to the programmed
terminal is open.
Drive parameter non-volatile storage is
corrupted.
External non-volatile storage has failed. Set
Control module was disconnected while
drive was powered.
The control module could not recognize
the power module.
The control module was mounted to a
power module with a different power
rating.
The control module was mounted to a
different drive type power module.
Keypad membrane failure /
disconnected.
Safety input enable hardware
malfunction. One of the safety inputs is
not enabled.
Microprocessor failure.
Troubleshooting Chapter 4
Action
• Cycle power.
• Check communications cabling.
• Check Modbus or DSI setting.
• Check Modbus or DSI status.
• Modify using C125 [Comm Loss
Action].
• Connecting I/O terminals C1 and C2
to ground may improve noise
immunity.
• Replace wiring, Modbus master
device, or control module.
• Cycle power.
• Reinstall option card in drive.
• Modify using C125 [Comm Loss
Action].
• Replace wiring, port expander,
option card, or control module.
• Cycle power.
• Check EtherNet/IP setting.
• Check drive' s Ethernet settings and
diagnostic parameters.
• Modify using C125 [Comm Loss
Action].
• Replace wiring, Ethernet switch, or
control module.
• 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.
Close input to the terminal and cycle
power.
Set P053 [Reset To Defalts] to 2 "Factory
Rset".
P053 [Reset To Defalts] to 2 "Factory
Rset".
Clear fault and verify all parameter
settings. Do not remove or install the
control module while power is applied.
• Cycle power.
• Flash with newer firmware version.
• Replace drive if fault cannot be
cleared.
Set P053 [Reset To Defalts] to any of the
reset options.
Set P053 [Reset To Defalts] to any of the
reset options.
• Cycle power.
• Replace control module if fault
cannot be cleared.
• 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.
• Cycle power.
• Replace control module if fault
cannot be cleared.
