Connection Of Rotary Encoder For Spindle Orientation; Analogue Output - HEIDENHAIN TNC 415 Technical Manual

2.3.3 Connection of rotary encoder for spindle orientation

The encoder for oriented spindle stop is connected at the input X6 (square-wave signals).
Max. input frequency: 300 kHz
HEIDENHAIN recommends using the ROD 426.xxx8 (1024 lines).

2.4 Analogue output

The TNC 425 from HEIDENHAIN permits installation of commercially standard amplifiers and motors
with AC technology. The output with the analogue nominal value voltage of the TNC's rpm controller
is connected with the torque input of the servo amplifier.
This drive concept eliminates the need for tachogenerators. The rpm actual value is measured by a
HEIDENHAIN incremental rotary encoder.
