SGD-01AS Yaskawa AC Frequency 100w Output Analog Servo Driver

Electrical Shock Hazard

Do not operate equipment with covers removed. Failure to comply could result in death or serious injury. The diagrams in this section may show drives without covers or safety shields to show details. Be sure to reinstall covers or shields before operating the drives and run the drives according to the instructions described in this manual. Always ground the motor-side grounding terminal. Improper equipment grounding could result in death or serious injury by contacting the motor case.

Do not perform work on the drive while wearing loose clothing, jewelry or without eye protection. Failure to comply could result in death or serious injury. Remove all metal objects such as watches and rings, secure loose clothing, and wear eye protection before beginning work on the drive.

Do not remove covers or touch circuit boards while the power is on. Failure to comply could result in death or serious injury.

Do not allow unqualified personnel to perform work on the drive. Failure to comply could result in death or serious injury. Installation, maintenance, inspection, and servicing must be performed only by authorized personnel familiar with installation, adjustment, and maintenance of AC drives.

Do not touch any terminals before the capacitors have fully discharged. Failure to comply could result in death or serious injury. Before wiring terminals, disconnect all power to the equipment. The internal capacitor remains charged even after the power supply is turned off. The charge indicator LED will extinguish when the DC bus voltage is below 50 Vdc. To prevent electric shock, wait at least one minute after all indicators are off and measure the DC bus voltage level to confirm safe level. Fire Hazard Tighten all terminal screws to the specified tightening torque. Loose electrical connections could result in death or serious injury by fire due to overheating of electrical connections. Do not use improper combustible materials. Failure to comply could result in death or serious injury by fire. Attach the drive to metal or other noncombustible material

.Do not use an improper voltage source. Failure to comply could result in death or serious injury by fire. Verify that the rated voltage of the drive matches the voltage of the incoming power supply before applying power
