POINT
When using the direct drive motor, set [Pr. PA01] to "_ _ 6 _".
For the test operation, refer to section 4.2.3, 4.3.3, 4.4.3, and 4.5.9.
After power on, the Z-phase mark of the direct drive motor must pass the
connector area once. In a system which prevents the direct drive motor from
making a full rotation, install the direct drive motor in a position where the Z-
phase mark can pass over the connector area.
