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