15. USING A DIRECT DRIVE MOTOR

15 - 4

CAUTION

When using the regenerative resistor, switch power off with the alarm signal.

Otherwise, a transistor fault or the like may overheat the regenerative resistor,

causing a fire.

Do not modify the equipment.

During power-on, do not open or close the power line of the direct drive motor.

Otherwise, it may cause a malfunction.

Connect the servo amplifier power output (U, V, and W) to the power input of the

direct drive motor (U, V, and W) directly. Do not let a magnetic contactor, etc.

intervene. Otherwise, it may cause a malfunction.

15.3 Operation and functions

POINT

When using the direct drive motor, set [Pr. PA01] to "_ _ 6 _".

For the test operation, refer to section 4.4.

The Z-phase pulse of the direct drive motor must be turned on after power-on.

When the machine configuration does not allow one or more revolution of the

direct drive motor, install the direct drive motor so that the Z-phase pulse can be

turned on.
