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.
