E.400: Power cord phase loss

Fault alarm reason

Main circuit input power line

phase loss

Fault alarm check

Check whether the main circuit

input L1,L2 and L3 are connected

disposal measures

Make sure that the wiring is correct

and that the correct voltage source

or voltage regulator is used in

series

P00-39.0 Open phase alarm can be

turned off

E.401: Undervoltage

Fault alarm reason

The input voltage of the main

circuit is lower than the rated

voltage value or there is no input

voltage

Fault alarm check

Check whether the main circuit

input L1,L2,L3 wiring is correct,

and the voltage value is how many

volts. The bus voltage can be

monitored via d23.dcp

disposal measures

Make sure that the wiring is correct

and that the correct voltage source

or series regulator is used

P00-52 Alarm threshold can be

modified

E.402: Overvoltage

Fault alarm reason

Main circuit input voltage is too

high

The regenerative resistor is not

connected or the type selection of

the regenerative resistor is

incorrect

Incorrect parameter settings

Drive hardware failure

Fault alarm check

Use voltmeter to test whether the

input voltage of main circuit is

correct

Check that the appropriate

regeneration resistor is connected

disposal measures

Use the correct voltage source or

series regulator

Properly connected matching

regenerative resistors

Confirm that the parameter settings

of P00-30~P00-34 are consistent

with the resistor connection mode

Overvoltage alarm still occurs

when the input voltage is

determined to be correct

Correct setting of parameters and

external regenerative resistance

Please send it back to the dealer or

the original factory for maintenance

E.410: Instantaneous overload

Fault alarm reason

The machine is stuck when the

Fault alarm check

Check mechanical connections for

disposal measures

Adjust the mechanical structure
