Cold start
Parameter data error Cause : The data input range in the parameter area is not
appropriate.
Example 1) 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.
Example 2) In rotary axis, when the index mode
is changed to the normal mode and
the soft limit negative side is 0, this
error is issued. Set the soft limit
negative side to a value -0.3mm is
added to the outer side of the
effective stroke. [Refer to 8.2 [2] Soft
limit +, Soft limit -]
Treatment : Change the value to the appropriate one.
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.
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).
0A3 Position command data
error
Cause : 1) The number for command is out of the range
when command was made with the direct
numerical command.
Treatment : 1) A code of a command that is out of the range
should be shown in the detail address. Input
an appropriate value by referring to these
values.

Cause : The number of input command pulses exceeded
the range of -134217728 to +134217728
(H'F8000000 to '07FFFFFF).
Treatment : Attempt to make the value of the electrical gear
ratio smaller (make the movement against the
unit bigger).
