2.32 Transducers for TNC 150 BR / TNC 150 OR
For cable lengths between transducers and control which exceed 20 m or for transducers which exceed
3040 mm, the control versions TNC 150 BR / TNC 150 OR al-e used.
2.3.2.1 Transducers and EXE-units for the X, Y, Z-axes
Transducers for the main axes X, Y, Z are connected to the control via 3-axis EXE-units with separate voltage
supply.
The following combinations are available:
Signal subdivision Gratiing pitch of NC-Linear transducer
transducer
25-fold 100 urn LB 326
5-fold 20 Urn LS 107, LS 703, LS 903
1 25;fold 1 IOO~m
1 LB 326
Rotary encoders may also be used instead of linear transducers. '
The max. cable length between EXE 8 . . and TNC 150.R is 50 m and 20 m between the transducer and the
EXE. The total cable length is therefore 70 m.
2.3.2.2 Transducers and EXE-units for axis IV
Subdivision within the pulse shaping electronics is always 5-fo:d.

When using a rotary encoder with integral pulse shaping electronics or the pulse shaping electronic unit
EXE 602, the voltage supply is provided by the TNC 150 R.
In order to maintain the correct supply voltage, the total lengtl of the connecting cable between EXE 602
and the control is limited to 10 m.
When using an ROD 800 in conjunction with an EXE 602, an extension cable between EXE 602 and the control
should not be used.
