Precautions ● When a voltage-dependent device or power factor-improving capacitor is present on output side The servo driver outputs PWM waves. Installation of a power factor-improving capacitor or a voltage-dependent resistor for lightning protection on the output side may cause instantaneous overcurrent or even damage to the servo driver; therefore, such installation shall not be used. ● Lightning impulse protection The servo driver of this series is equipped with a lightning overcurrent protector for protection against induced lightning.
Yet if the product is installed in a place subject to frequent lightning, installation of an additional lightning protection device before the servo driver is required. ● Altitude and derating At places with the altitude exceeding 1,000 m where heat dissipation and safety insulation reduce due to thin air, the servo driver shall be subject to derated use. For specific details, please contact us for technical advice. ● Precautions for scraping of the servo driver Burning of the electrolytic capacitors of the main circuit and printed circuit board may result in explosion, and burning of plastic parts may generate toxic gases. Please dispose of the controller as a kind of industrial waste.
