failure

E.621: Encoder built-in data mismatch

Fault alarm reason

Encoder read/write exception

Abnormal motor parameter setting

Fault alarm check

Check the encoder wiring.

Correctly set the motor parameters

of P00-00~ P00-19

disposal measures

correct wiring

Set parameters correctly

E.622: Encoder built-in data check error

Fault alarm reason

Encoder built-in data verification

error

Fault alarm check

Check Encoder Wiring

Verify encoder shield wire is

properly connected

disposal measures

If the connection is normal, return

the drive to the factory for repair

E.641: Encoder overheating (encoder internal)

Fault alarm reason

Encoder overheating (inside

encoder)

Fault alarm check

Check encoder temperature

disposal measures

If the temperature is normal, the

alarm can be cleared by F06.EN0

Modify parameter P00-07.2 Alarm

Off

E.643: Bus Encoder Battery Failure

Fault alarm reason

Low external battery voltage

when bus encoder is set to

multi-turn absolute value

Fault alarm check

Check the voltage of the external

battery of the encoder and confirm

that it is higher than 3.0V

disposal measures

When the battery voltage is lower

than 3.0V, replace the battery.

Alarm cleared above 3V using

auxiliary function F06.EN0

Alarm can be switched off via

parameter P00-07

E.644: Bus Encoder Multi-turn Exception

Fault alarm reason

Bus encoder turns out of range

Fault alarm check

The number of turns can be

monitored through the monitoring

mode d21.ASH, and the multi-turn

absolute motor cannot rotate in one

direction for a long time.

disposal measures

Clear the multi-turn value using the

command F07.En1
