binding

Check P00-50 parameter value

Set P00-50 parameters correctly

Confirm that the mechanical part is

E.412: Sustained overload

Fault alarm reason

Continuous use beyond the drive

rated load

Improper setting of control

system parameters

Motor wiring error

Fault alarm check

Can be monitored via d13.oL. in

monitor mode

1. Whether the mechanical system

is installed

2. Acceleration setting constant is

too fast

3. Whether the gain parameters are

set correctly

Check U, V, W wiring

disposal measures

Change to a higher power motor or

reduce the load

1. Adjust the gain of control loop

2. Acceleration and deceleration

setting time slows down

correct wiring

E.420: Overspeed

Fault alarm reason

Input speed command too high

Unreasonable setting of overspeed

judgment parameters

Fault alarm check

Check whether the input signal is

normal

Check whether P04-05 (overspeed

alarm value) is set properly

disposal measures

Adjust the frequency of the input

signal

Set P04-05 correctly (overspeed

alarm value)

E.421: Out of control detection

Fault alarm reason

Motor power lines U,V,W wiring

error

Incorrect motor parameter setting

Fault alarm check

Check wiring

disposal measures

correct wiring

Check P00-05; and whether the

encoder parameters are set correctly

Set parameters correctly

Set P00-46.1 to 0 to close runaway

detection
