4.11 Encoder Connector

Three encoder connectors (one dedicated encoder interface and connector per axis) are available. A

standard 2.54mm pitch two row header is used for encoder connection. Incremental a/b/n encoder with

diﬀerential or single ended (push-pull TTL or open-drain) output signals are supported.

For encoder with single ended output signals the non-inverting inputs of the encoder connector should be

used (A+, B+ and N+). Please do not activate encoder line termination for single ended encoder signals

(remove jumpers). Refer to section 5 for more details.

For encoder with diﬀerential output signals the non-inverting and inverting signal pairs should be con-

nected (A+ and A-, B+ and B-, N+ and N-) and on-board line termination might be activated (setting jumpers

- refer to secton 5 for more details).

Incremental encoders with +24V push-pull output signals are not supported. Please use appropriate

interface circuits for these types of encoders.
