Important notes

DANGER
Serious risk of injury!
  • Only specialist personnel with extensive knowledge in the areas of electrical engineering / drive technology are allowed to install and commission the equipment.
  • The surface temperature of the motor can exceed 100 °C in operation. Check (measure) the temperature of the motor. Wait until the motor has cooled down below 40 °C before touching it.
  • Make sure that, even if the drive starts to move unintentionally, no danger can result for personnel or machinery.
Note
Overloading of the gear!

With motor / gear combinations can in case of failure (mechanical blockage of the power train) due to high ratio, the gear will be overloaded.

To prevent this, make sure that the motor rated torque and the motor peak torque is limited in the servo drive.

Example:

  • Motor rated torque / motor peak torque: 1 Nm / 5 Nm
  • Gear rated torque / gear peak torque: 15 Nm / 24 Nm
  • Gear ratio: i = 10
  • The motor rated torque is not limited. The motor peak torque is limited to 2,4 Nm.
