Varistor or Power Factor Improvement Capacitor on Inverter Output
Servo drive outputs PWM wave. Do not use servo drive, if a power factor improvement capacitor or a lightning varistor is on output side, which
may easily result in transient overcurrent of servo drive, or even damage servo drive.
Surge Protection
A surge protection device is installed in servo drive to prevent it from induction lightning stroke on a certain degree. Additional protection
devices are required in front of servo drive in the places where thunder and lightning occur frequently.
Altitude and Derating
When servo drive is used in an area at an altitude of over 1,000m, the cooling effect will degrade, so it must be derated. For details, please
consult SINEE.
Attentions at Servo Drive Scrapping
Burning the electrolytic capacitors of the mains and PCB may result in explosion and burning plastic parts may generate toxic gas. Please handle
them as industrial wastes when servo drive is scrapped.
