CAUTION
This chapter does not describe the following items. For details of the items, refer to each section of the
detailed description field.

15.3 Operation and functions

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.
Connect the servo amplifier power output (U/V/W) to the power input of the direct
drive motor (U/V/W) directly. Do not let a magnetic contactor, etc. intervene.
Otherwise, it may cause a malfunction.

Connecting a servo motor for different axis to the U, V, W, or CN2 may cause a
malfunction.
Before wiring, switch operation, etc., eliminate static electricity. Otherwise, it may
cause a malfunction.

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.
