the instructions below.
Please refer to the Instruction Manual for other alarms.
Error Code
Error Description
Cause and Treatment
069
Real Time Clock
Operation Stop Detection
It indicates the calendar function has stopped and the current
time data has lost.
Have the clock settings again from the teaching tool.
0B8
Excitement Detection Error
The detection of excitation is conducted when the servo is turned
ON for the first time after the power is supplied. The status is that
the detection did not complete even after a certain time (set in
Parameter No.29) was passed.
1) Connection error or wire breakage of motor/encoder cables
2) Brake is not released (when equipped with a brake).
3) Load to the motor is high due to external force.
4) Power was turned on while touching to the mechanical end.
5) The slide resistance of the actuator itself is large.
Those described above can be considered.
0E5
Encoder Receive Error
This error code appears when the right signal was not received
from the encoder side to the controller command. Check if any
wire breakage on a connector and the condition of wire
connections. If no error is generated under the condition that the
power to all the peripheral equipment is shut and operate only
this controller and the actuator, noise can be considered as the
cause of the problem.
0E8
A- and B-Phases
Breakage Error
It is the condition that the encoder signal is not properly
detected.
Check if any wire breakage on a connector and the condition of
wire connections.
0EE
Absolute Encoder Error
Detection 2
This error code appears when the absolute encoder PCB cannot
detect the position information properly. The voltage for the
absolute data battery is dropped. Check the battery alarm output
on PIO, and if it is off, replace the battery. Perform Absolute
Reset after the replacement.
Check the encoder cable connection.
20A
Servo OFF While in
Operation
It shows the operation command was generated in the condition
that the servo is OFF.
Resume the operation after turning the servo ON.
