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

16.3 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 direct drive motor power
input (U/V/W) directly. Do not let a magnetic contactor, etc. intervene. Otherwise,
it may cause a malfunction.

Connecting a servo motor of the wrong axis to U, V, W, or CN2 of the servo
amplifier 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 4.2.3, 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.
