Aservo system consists of three main components: the controller, the power-driveunit, the feedback device, and the motor.
• Controller –continuously compares the reference value from the CNC system with the actualvalue measured by the feedback device and adjusts the control variableaccordingly.
• Power-drive unit –forms the system’s main power loop. On one hand, it applies electrical energyfrom the mains to the motor in proportion to the control variable, regulatingmotor torque; on the other hand, it converts theconstant-voltage/constant-frequency mains supply into the AC or DC powerrequired by the motor.
• Motor – converts the suppliedelectrical energy into mechanical motion, driving the load in accordance withthe power delivered.
EnvironmentalSpecifications
Operatingtemperature / humidity: 0 – 55 °C(no freezing), ≤ 90 % RH (non-condensing).
Storagetemperature / humidity: –20 – 65 °C(no freezing), ≤ 90 % RH (non-condensing).
Ambientatmosphere: inside a control cabinet free of corrosive or flammable gases, oilmist, dust, etc.
Altitude:≤1 000 m above sea level.
Vibration:≤0.5 G (4.9 m/s²), 10 – 60 Hz (non-continuousoperation).
Protection:The servo drive itself is not protected; it must be installed in a well-sealedelectrical enclosure that prevents ingress of corrosive or flammable gases,conductive objects, metallic dust, oil mist, or liquids.
