Operation

PWRT signal detection
in incomplete home
return
Cause : The current position write signal PWRT was input
in the teaching mode of PIO pattern 1 when home
return was not yet completed.
Treatment : Input the HOME signal first to perform home
return, and then input the PWRT signal after
confirming that the home return has completed
(HEND output signal is ON).
0A1
Cold start
Parameter data error
Cause : The data input range in the parameter area is not
appropriate. This error occurs when the magnitude
relationship is apparently inappropriate such as
when 300mm was incorrectly input as the value of
the soft limit negative side while the value of the
soft limit positive side was 200.3mm.
Treatment : Change the value to the appropriate one.
0A2
Operation
release
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.
