16. USING A DIRECT DRIVE MOTOR
16 - 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.
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.

16.3 Operation and functions
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.
