Alarm
Code
Alarm
Level
Alarm Name Cause/Treatment
0A7
Operation
release
Command deceleration
error
Cause : Because there is not enough deceleration distance
when the deceleration is changed to a lower setting
during the operation, the actuator exceeded the soft
limit when deceleration was made from the current
position with the deceleration after the change.
Soft limit
Deceleration starting position
not resulting in soft limit overshoot If a command is issued here,
soft limit overshoot will occur.
The cause is that the timing to make the next
movement command when the speed was changed
during the operation was late.
Treatment : Make the timing earlier for the movement command
for the deceleration speed change.
0A8 Unsupported
motor/encoder types
Cause : The motor connected to the controller is not
applicable or the type of the encoder that the motor
is connected is not applicable.
Treatment : Please contact us if the alarm is issued even with
the applicable actuator and the same problem
happens again even after rebooting the power.
0A9 Loadcell data error Cause : The data acquired from loadcell at power-on or
software reset is incorrect.
Treatment : 1) Effect of noise is suspected. Check if there is a
device radiating the noise and have a treatment
to prevent receiving the noise.
2) The loadcell may be faulty. If the error keeps
occurring even with the power reboot for several
times, it is considered the loadcell is
malfunctioned. Please contact IAI.
0B3 Spurious absolute error Cause : Home-return operation was not performed properly.
1) Work is interfering with peripheral equipment in
the middle of home return.
2) Encoder Error
Treatment : 1) Remove the interference.
2) Please contact IAI.
0B4
Cold start
Electric angling
mismatching
Cause : This alarm indicates that the position deviation
counter has overflowed.
Treatment : The alarm occurs when the actuator cannot be
operated.
Confirm about the load conditions, that the work
does not interfere with any object nearby or the
brake has been released, etc.
If the error occurs even when the servo is ON, the
cable breakage or disconnection is considered.
Check the cable connection. Please contact IAI if
there is no failure in the cable and connector
connections.
0B5
Operation
release
Z-Phase position error The position where the Z-phase is detected before the home
return operation, is out of the specified range.
Cause : Encoder Error
Treatment : Please contact IAI.
