2.11 Colour and contact assignments for encoders
The incremental encoder connection is an input for a type with two tracks and TTL-compatible signals
for EIA RS 422-compliant drivers. The maximum current consumption of incremental encoders must
not exceed 150 mA.
The pulse number per rotation can be between 500 and 8192 increments. This is set with the normal scaling via parameter
P301 "Incremental encoder pulse number" in the menu group "Control parameters". For cable lengths > 20 m and motor speeds
above 1500 rpm the encoder should not have more than 2048 pulses/revolution.
