High power AC motors are typically inductive in design. An inductive rotor is constructed by laminating iron disks together to form the central core of the rotor. Slots around the circumference of the core receive conductors, termed ‘rotor bars’ which are shorted together at either end of the rotor. This is accomplished by ‘end rings’ which may be welded to the ends of the rotor bars, or the end rings and rotor bars may be injection molded around the core, effectively forming a single, homogenous structure.

When the rotor is assembled inside of the stator, current flow through the stator windings generates corresponding ‘induced’ current flow through nearly aligned, adjacent rotor bars. This current path is completed by the end rings, creating a closed circuit. The induced current flow generates magnetic force in the rotor, compelling it to rotate to keep the stator and rotor fields aligned. The greater the misalignment, the greater the induced current and therefore the higher the electromotive force (emf)
and torque generated.

Always follow the specified installation method.

The Servopack generates heat. Install the Servopack so that it can radiate heat freely. Note also that the Servopack must be in an environment free from condensation, vibration and shock.

Perform noise reduction and grounding properly.

If the signal line is noisy, vibration or malfunction will result.

• Separate high-voltage cables from low-voltage cables.
• Use cables as short as possible.
• Use at least class 3 grounding (ground resistance 100Ω or below) for the Servomotor and Servopack.
• Never use a line filter for the power supply in the motor circuit.

Conduct a voltage resistance test under the following conditions.

• Voltage: 1,500 Vrms AC, one minute
• Braking current: 20 mA
• Frequency: 50/60 Hz
• Voltage applied point: Between R, T terminals and frame ground (connect terminals R and T securely.)

Use a fast-response type ground-fault interrupter.

For a ground-fault interrupter, always use a fastresponse type or one designed for PWM inverters. Do not use a time-delay type.

Do not perform continuous operation under overhanging load.

Continuous operation cannot be performed by rotating the motor from the load and applying regenerative braking. Regenerative braking by the Servopack can be applied only for a short period, such as the motor deceleration time.

The Servomotor cannot be operated by turning the power ON and OFF.

Frequently turning the power ON and OFF causes the internal circuit elements to deteriorate. Always start or stop the servomotor by using reference pulses.
