Cause/Treatment
0A2
Position data error
Cause
: 1) A move command was input when no target
position was set in the “Position” field of a
position No. in the position table.
2) The value of the target value in the “Position”
field exceeded the Parameter No.3 and 4 “Soft
limit set value”.
3) A target position was specified in the “Position”
field by relative coordinate in the solenoid valve
mode 2 of PIO pattern 5.
4) Pressing operation was specified while the
vibration suppress control function remained
effective.
Treatment : 1) Set the target position.
2) Change the target position value to the one
within the soft limit set value.
3) The target position cannot be set by relative
coordinate (incremental feed).
4) The vibration suppress control function and
pressing operation cannot be used concurrently.
Provide setting so that either of the functions is
effective.
0A3
Position command data
error
Cause
: 1) The speed or acceleration/deceleration value
during direct numeric specification exceeded the
maximum set value.
2) Pressing operation was specified in the field bus
specification while the vibration suppress
function remained effective.
Treatment : 1) Table to input a proper value.
2) The vibration suppress control function and
pressing operation cannot be used concurrently.
Provide setting so that either of the functions is
effective.
0A5
Operation
release
Electromagnetic brake
unreleased error
Cause
: The brake cannot be released.
Treatment : Supplied the 24V power unit for the
electromagnetic brake.
0A6
Cold start
Dynamic brake not
released
Cause
: The dynamic brake cannot be released when the
servo is ON due to noise and electrostatic, etc.
Treatment : Implement measures to eliminate noise or
electrostatic. There is a concern of circuit
breakdown. Please contact IAI.
0A7
Operation
release
Command deceleration
error
Cause
: Even though the deceleration setting was changed
lower during a movement, because there is not
enough deceleration distance for the deceleration
from the current position, the actuator exceeded
the soft limit.
Deceleration starting position
not resulting in soft limit overshoot
If a command is issued here,
soft limit overshoot will occur
Soft limit
Treatment : Make the timing earlier for the movement
command for the deceleration speed change.
