Step Operation
Example of Rotary Axis Operation Setting
If the rotary axis operation is specified, the shaft moves in a direction nearest from the current position to a
target position of a step parameter that the rotary axis operation (rotary) has been specified regarding
32.Pr03 (Movement per rotation in rotation coordinates) as 360 degrees.
A current position of running motor is automatically limited in a range between 0 and [travel per rotation at a
rotary coordinate –1] as shown below.

Point 1 = 1250
Point 4 = 5000
Point 7 = 8750

Point 6 = 7500Point 2 = 2500

coordinate is set to “10000”

Caution
1) Control mode
The rotary axis operation is enabled only for the position control (SV.Pr02 = 0). If the rotary axis operation
is specified for the full-closed control (SV.Pr02 = 6), an error code No. 69 (undefined data error protection)
is shown.
2) Restrictions on parameter
If the rotary axis operation is used, the restrictions below are imposed to the parameters not to exceed the
limitation of the current position.

Description
The rotary axis operation requires homing. If “0” or “2” is
set, an error code No. 69 (undefined data error protection)
is shown when the rotary shaft operation starts.
Be sure to set “1” if you use the home offset function.
The rotary axis operation requires homing.
The combined block operation cannot be used.
For 16.Pr37 = 0, set “0”. For 16.Pr37 = 0, set a value in a
range between 0 and [movement per rotation at a rotary
coordinate - 1].
For any invalid value out of specified range, an error code
No. 69 (undefined data error protection) is shown when
the positioning operation starts.
A maximum travel limitation error protection cannot be
used for the rotary axis operation.
