Siemens Answers with External Absolute and Incremental Motor Encoder Technology — For the Most Precise Motion Control

And Now They're Field Replaceable

absolute incremental motor encoder

Siemens offers built-on absolute and incremental motor encoders to measure speeds, angles or paths when the mechanical drive train does not provide an accurate reading from the motor-integrated encoder.

For example, if a motor is driving rolls for web handling and the web slips; an encoder mounted to a surface-sensing roll could measure the real web speed, which is critical to the production process. External encoders can also help to improve the motion control quality of weak mechanicals systems with play in the drive train between motor and load, and subsequently close the position control loop.

As a result, the external motor encoder system can more accurately control the movements of weak and loose mechanical systems, improving product quality and increasing productivity. Siemens offers optoelectronic external encoders to measure speeds, angles or paths in high resolution. These encoders can be used in conjunction with motion controllers; CNCs drive systems, or PLCs offered by Siemens. This includes SIMOTION, SINUMERIK, SIMATIC, SINAMICS, SIMODRIVE and MASTERDRIVES.

New - Field Replaceable Motor Encoder Design

Siemens combines the electronics for the encoder itself with the communication parts for the electronic rating plate. Thus the encoder is vibration separated from the motor by a coupling which also allows it to be replaced in the field without signal alignment needs.

You can replace the Encoder without un- mounting the motor from the machine

  • Saves you time and money

  • Your machine is up and running faster

  • Production continues
