3 – 50 HEIDENHAIN Technical Manual TNC 426, TNC 430
3.8 Analog Output
Output: ±10 V
Maximum load of outputs: 2 mA
Maximum capacity: 2 nF
13 analog outputs are available:
n Connection X8: Analog output 1 to 6
n Connection X9: Analog output 7 to 13
PLC analog output The PLC analog outputs can be controlled through Module 9130.
(See “Overview of Modules” on page 5 – 3).
3.8.1 Nominal Value Output
Please note:
n For analog axes and analog spindle, use MP120.x and MP121.x to assign the
corresponding analog outputs on terminal X8 or X9 to the nominal speed
outputs.
n The connecting cables to the nominal value outputs must not have more
than one intermediate terminal.
n If you must branch to physically separate servo inputs, the connection must
be made in a grounded terminal box, e.g. Id. Nr. 251 249-01 from
HEIDENHAIN.
The housing of the terminal box must be electrically connected with the
frame of the machine.
n The 0 V connections of the nominal-value-difference inputs must be
connected with the signal ground. Cross section ≥ 6 mm
2
n Use only original HEIDENHAIN cables and connecting elements.
