EEP
EEPROM fault
Error of controlling the write
and read of the parameters
Damage to EEPROM
Press STOP/RST to reset
Change the main control

PIDE
PID feedback fault
PID feedback offline
PID feedback source
disappear
Check the PID feedback
signal
Check the PID feedback

bCE
Braking unit fault
Braking circuit fault or
damage to the braking
pipes
The external braking
resistor is not sufficient
Check the braking unit and
change new braking pipe
Increase the braking
resistor
ETH1

Check if the connection of
the motor is normal or not
Change the hall
Change the main control
panel
Set motor parameters
correctly.
ETH2

fault 2
dEu
Velocity deviation
fault
The load is too heavy or
stalled
Check the load and ensure
it is normal
Increase the detection time
Check whether the control
parameters are normal
STo
Maladjustment fault
The control parameters of
the synchronous motors not
set properly
The autotune parameter is
not right
to the motor
Check the load and ensure
it is normal
Check whether the control
parameter is set properly or
not
Increase the maladjustment
detection time

fault
The connection of the
keypad wires is not good or
broken
The keypad wire is too long
and affected by strong
Check the keypad wires
and ensure whether there is
mistake
Check the environment and
avoid the interference
