Troubleshooting
A.bF0
System Alarm 0
(Internal program processing
error)
A SERVOPACK program error (internal program error 0) occurred.
A.bF1
System Alarm 1
(Internal program operating
error)
A SERVOPACK program error (internal program error 1) occurred.
A.bF2
System Alarm 2
(Program error in current control
processor)
A SERVOPACK program error (internal program error 2) occurred.
A.bF3
System Alarm 3
(Error in Encoder interface
processor)
A SERVOPACK program error (internal program error 3) occurred.
A.bF4
System Alarm 4
(CPU WDT error)
A SERVOPACK program error (internal program error 4) occurred.
A.C10 Servo Run-away The Servomotor was overrunning.
A.C80
Encoder Clear Error Multiturn Limit
Setting Error The absolute encoder's multiturn count was cleared or it could not be set
properly.
A.C90 Encoder Communication Error
Communications could not be established between the Encoder and SER-
VOPACK.
A.C91
Encoder Communication
Position Data Acceleration Error
An error occurred in the encoder's position data calculation.
A.C92
Encoder Communication
Timer Error An error occurred in the timer used for communications between the
Encoder and SERVOPACK.
A.CA0 Encoder Parameter Error The Encoder's parameters are corrupted.
A.Cb0 Encoder Echoback Error The contents of communications with the encoder are incorrect.
A.CC0 Multiturn Limit Mismatch The Encoder and SERVOPACK Multiturn Limit Values do not agree.
A.d00 Excessive Position Error The position error pulses exceeded the setting in parameter Pn520.
A.d01
Excessive Position Error Alarm at
Servo ON When the Servo went ON, the position error pulse count exceeded the
value set in parameter Pn 526.
A.d02
Excessive Position Error Alarm for
Speed Limit at Servo ON
The speed limit in parameter Pn529 is applied if the Servo goes ON and the
position error pulse count was excessive. Reference pulses were input in
that condition and the value set in parameter Pn520 was exceeded without
clearing the speed limit.
A.F10 Broken Phase in Power Line One phase of the three-phase main power supply is not connected.
CPF00 Digital Operator
Communications Error Communications could not be established between the JUSP-OP05A Digi-
tal Operator and SERVOPACK due to a CPU Error or other problem.
CPF01
A. − − No error display Indicates normal operating status.
