Recifier fault code
Fault type
Possible cause
Solution
EEPROM is damaged.
board.
OL
Rectifier unit overload
fault
The rectifier unit releases
overload pre-alarm based on
the set value.
Check the load and overload
pre-alarm threshold.
bCE
Braking unit direct
connection fault
Fault occurred to the brake
circuit or the braking pipe is
damaged;
Check the braking unit, and
replace with new braking pipe.
Increase the brake resistance.
bOL
Braking pipe overload
Fault occurred to the brake
circuit or the braking pipe is
damaged;
Resistance of the external
braking resistor is small.
Check the braking unit, and
replace with new braking pipe.
Increase the brake resistance.
bOC
Brake overcurrent
Fault occurred to the brake
circuit or the braking pipe is
damaged;
Resistance of the external
braking resistor is small.
Check the braking unit, and
replace with new braking pipe.
Increase the brake resistance.
E-DP
PROFIBUS
communication fault
The communication address
is incorrect;
The matching resistor is not
switched on improperly;
The GSD file of the master
station is set improperly;
The peripheral interference is
too large.
Check the related settings;
Check the surrounding
environment, and eliminate
interference effects.
E-NET
Ethernet
communication fault
The address of Ethernet is set
improperly;
Ethernet communication
mode is selected improperly;
The peripheral interference is
too large.
Check the related settings;
Check the communication
mode selection;
Check the surrounding
environment, and eliminate
interference effects.
E-CAN
CANopen
communication fault
Line contact is poor;
The matching resistor is not
switched on;
Communication baud rates do
not match;
The peripheral interference is
too large.
Check the line;
Switch on the matching
resistor;
Set the same baud rate;
Check the surrounding
environment, and eliminate
interference effects.
OFFL
Certain slave units
offline
The number of actual slave
nodes (P17.15) conflicts with
the number of set slave nodes
(P21.33);
Line contact is poor;
The matching resistor is not
switched on.
Communication baud rates do
not match;
The master/slave addresses
conflict.
Check the values of P17.15
and P21.33.
Switch on the matching
resistor;
Set the same baud rate;
Check all master/slave
addresses;
Check CANopen network
parameters.
