Equipment configuration

The following shows the configuration of a direct drive motor. When using the direct drive motor, note the following.

Minimum oscillation angle

For a direct drive motor that performs a rotating oscillating motion within 70 ˚, rotate the motor more than 90 ˚ at least once a

day to keep the bearings lubricated.

Z-phase position

When the Z-phase mark on the rotor end of the direct drive motor is in the connector area, the Z-phase pulse is on (Z-phase

mark passing). Keep the Z-phase position visible even after the direct drive motor is installed to a machine.

Precautions for Z-phase mark passing

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 or more, install the direct drive motor in a position where the Z-phase mark

can pass over the connector area.

To make the Z-phase mark pass the connector area, the Z-phase mark needs to be rotated ±15 ˚ or more with respect to the

center of the connector mounting part.
