    9.4 Electrical Installation All work should be carried out with power off. DANGER Electric servo actuators and motors have dangerous live and rotating parts. All work during connection, operation, repair and disposal must be carried out only by qualified personnel as described in the standards EN 50110-1 and IEC 60364! Before star- ting any work, and especially before opening covers, the actuator must be properly isolated.

    10. Decommissioning and Disposal The gears, servo actuators and motors from Harmonic Drive AG contain lubricants for bearings and gears as well as electronic components and printed circuit boards. Since lubricants (greases and oils) are considered hazardous substances in accordance with health and safety regulations, it is necessary to dispose of the products correctly.

Glossary 11.1 Technical Data AC Voltage constant k / 1000 rpm] Effective value of the induced motor voltage measured at the motor terminals at a speed of 1000 rpm and an operating tempera- ture of 20 °C. Ambient operating temperature [°C] The intended operating temperature for the operation of the drive.

  • Page 88 [Nm] In the event of an emergency stop or collision, the Harmonic Drive® Gear may be subjected to a brief momentary peak torque. The magnitude and frequency of this peak torque should be kept to a minimum and under no circumstances should the momentary peak torque occur during the normal operating cycle.
  • Page 89 The ratio is the reduction of input speed to the output speed. Note for Harmonic Drive® Gears: In the standard drive arrangement, the Wave Generator is the drive element while the Flex- spline is the driven element and the Circular Spline is fixed to the housing. Since the direction of rotation of the input (Wave Generator) is opposite to the output (Flexspline), a negative ratio must be considered.
