A．43
╳
Servo drive type error
The parameter setting of servo drive does not match the
servomotor.
A．45
╳
Absolute encoder multiturn
information error
Absolute encoder multiturn information is faulty.
A．46
╳
Absolute encoder multiturn
information overflow
Absolute encoder multiturn information overflow.
A．47
╳
Battery voltage below 2.5V
Absolute encoder multiturn information is lost.
A．48
╳
Battery voltage below 3.1V
Battery voltage is too low.
A．50
╳
Serial encoder communication
overtime
Encoder disconnected; encoder signal disturbed; encoder
error or encoder decoding circuit error.
A．51
╳
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 servo drive is not turned ON when
the battery voltage is normal, or the servomotor running
acceleration is too high due to external reason.
A．52
╳
Absolute state of serial encoder
error
Encoder or the encoder decoding circuit is faulty.
A．53
╳
Serial encoder calcaution error
Encoder or the encoder decoding circuit is faulty.
A．54
╳
Parity bit or end bit in serial encoder
control domain error
Encoder signal is disturbed or the encoder decoding circuit
is faulty.
A．55
╳
Serial encoder communication data
checking error
Encoder signal is disturbed or the encoder decoding circuit
is faulty.
A．56
╳
End bit in serial encoder control
domain error
Encoder signal is disturbed or the encoder decoding circuit
is faulty.
A．58
╳
Serial encoder data empty
The EEPROM data of serial encoder is empty.
A．59
╳
Serial encoder data format error
The EEPROM data format of serial encoder is incorrect.
A．66
╳
CAN communication abnormal
CAN communication is faulty because of abnormal
communication connection or disturbance.
A．67
╳
Receiving heartbeat timeout
The master station sends heartbeat time timeout.
A．68
╳
CAN Synchronization frame interval
is too short
The filling time and the cycle of the synchronous frame
does not matchor communication is faulty.
A．69
╳
CAN Synchronization frame interval
is too long
The filling time and the cycle of the synchronous frame
does not match or communication is faulty.
A．00
〇
Not an error
Normal operation status.
〇：Output transistor is ON.
╳：Output transistor is OFF.
