System integration 7.2 Encoders

Note

To ensure a high control loop dynamic response (high kV factor), rapid, overshoot-free positioning, and smooth running, measuring systems that emit a minimum of approx. 10,000 pulses/revolution are recommended.

Note

To protect against contamination, the housing for the encoder on the axes construction of the built-in torque motor must fulfill degree of protection IP54 to EN 60529.

The permissible mechanical speed and limit frequency of the encoder and Control Unit must be taken into account. Refer to the appropriate documentation issued by the manufacturer when configuring, installing, and adjusting the encoder
