[Cd.3] Positioning start No.

Set the positioning start No.
(Only 1 to 600 for the Pre-reading start function. For details, refer to Section
13.7.7 "Pre-reading start function".)
Fetch cycle: At start
Note) After the positioning start is requested, do not change the setting value before
the start complete signal ([Md.31] Status) is turned ON.
[Cd.4] Positioning starting point No.

Set a "starting point No." (1 to 50) if block start data is used for positioning.
(Handled as "1" if the value of other than 1 to 50 is set.)

[Cd.5] Axis error reset

Clears the axis error detection, axis error No., axis warning detection and axis
warning No.

When the axis operation state of Simple Motion module is "in error occurrence",
the error is cleared and the Simple Motion module is returned to the "waiting"
state.

Clears the both of Simple Motion module errors and servo amplifier errors by axis
error reset.
(Some servo amplifier alarms cannot be reset even if error reset is requested. At
the time, "0" is not stored in [Cd.5] by the Simple Motion module. It remains "1".
Set "0" in [Cd.5] and then set "1" to execute the error reset again by user side.
Refer to each servo amplifier instruction manual for details.)

The error cannot be reset during a forced stop. Execute the axis error reset after
the forced stop is released. [CiA402 mode]

"stopped"), set "1" in [Cd.6]. Positioning will be carried out again from the stopped
position to the end point of the stopped positioning data.
