System integration 7.2 Encoders

WARNING

Incorrect commutation can result in uncontrolled motor movements.

When the encoder is replaced, make sure that the commutation setting is correct. The procedures involved here must only be carried out by trained personnel.

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

Note

The encoder pulse numbers must be able to be divided by 10 or 16 in order to be able to use the zero mark monitoring function of the drive system.
