O: Output transistor is ON. X: Output transistor is OFF.
A.45, A.46, A.47, A.51 only can be reset when the absolute encoder related alarm is cleared.
The multiturn data should be cleared because of the multiturn information is incorrect.
Alarm
Display
Alarm
Output
Alarm Name Meaning
A.47 X Battery voltage below 2.5 V Absolute encoder multiturn information is loss.
A.48 X Battery voltage below 3.1 V Battery voltage is too low.
A.50 X
Serial encoder communication
overtime
Encoder disconnected; encoder signal disturbed; encoder
error or encoder decoding circuit error.
A.51 X
Absolute encoder overspeed
alarm detected
Absolute encoder multiturn information may be faulty.
Error reasons:
1.The battery is not connected or the battery voltage is
insufficient.
2.The power supply to servodrive is not turned ON when the
battery voltage is normal, or the servomotor running
acceleration is too high due to external reason.
A.52 X
Absolute state of serial
encoder error
Encoder or the encoder decoding circuit is faulty.
A.53 X
Serial encoder calculation
error
Encoder or the encoder decoding circuit is faulty.
A.54 X
Parity bit or end bit in serial
encoder control domain error
Encoder signal is disturbed or the encoder decoding circuit
is faulty.
A.55 X
Serial encoder communication
data checking error
Encoder signal is disturbed or the encoder decoding circuit
is faulty.
A.56 X
End bit in serial encoder control
domain error
Encoder signal is disturbed or the encoder decoding circuit
is faulty.
A.58 X Serial encoder data empty The EEPROM data of serial encoder is empty.
A.59 X
Serial encoder data format
error
The EEPROM data format of serial encoder is incorrect.
A.60 X
Communication module not
detected
Communication module is not plugged or the communication
module is faulty.
A.61 X Communication unsuccessful CPU of communication module operated abnormally.
A.62 X
Servodrive can not receive the
period data of communication
module.
Receive channel of servodrive data or send channel of
communication module is faulty.
A.63 X
Communication module can
not receive the servodrive
response data.
Communication module is faulty.
A.64 X
Communication module and
bus connectionless
Bus communication is faulty.
A.66 X CAN communication abnormal
CAN communication is faulty because of abnormal
communication connection or disturbance.
A.67 X Receiving heartbeat timeout The master station sends heartbeat time timeout.
A.69 X
Synchronization signal monitor-
ing cycle is longer than setting.
The filling time and the cycle of the synchronous signal does
not match.
A.00 O Not an error Normal operation status.
