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.
Z-phase pulse is on
(Z-phase mark passing)
when the Z-phase mark
on the rotor end of the
direct drive motor is in
the connector area.
