Bipolai outputs (PL 110 B: A25 to A30 and A57 to A62)
Nominal voltage: 15 V
(measured between two bipolar outputs, with one output is switched to signal "1" and the other to signal "0")
Nominal current: 300 mA
Voltage range with nominal current: 14.6 V to 15.5 V
Max. output current 1.2 A for 1 minute
Current limitation range: 1.35 A to 1.6 A
Permissible load: Resistance load;
inductive load only with quenching diode parallel to inductivity
max. switching frequency: 50 Hz
Please note:
Bipolar PLC-outputs may not be switched in parallel.
When using the bipolar outputs as binary output signals:
Voltage for signal "1": ,~14.2 V
Voltage for signal "0": d 3.0 V
Nominal current: 300 mA
Max. output current 1.2 A for 1 minute
Output current supervision
Supervision of output currents of all bipolar outputs. Outpui J3/11 provides signal "1" if the sum of the out-
put currents of all bipolar outputs is 70.8 A to 0.9 A
Nominal voltage: 24 V, -
Max. output current: 55 mA to 65 mA
Max. difference to supply voltage: ~1.5 V
2.3 Transducers for TNC 150
23.1
Transducers for TNC 150 B / TNC 150 Q
The TNC 150 controls the actual position with a digital step of 0.001 mm and subdivides the grating period
of the transducers by 20 x or 10 x. Incremental linear transducers with a 20 urn or 10 urn grating pitch such as
.LS 107 (measuring lengths 240 mm to 3040 mm)
.LS 703 (measuring lengths 170 mm to 3040 mm)
.LS 903 (measuring lengths 70 mm to 1240 mm)
.LID 300,310
should therefore be used.
If accuracy requirements are permitting, indirect measuring :;ystems e.g. rotary encoders type ROD 450 or
ROD 456 may be connected to the drive spindles. The requj-ed number of lines for the encoder is calculated
as follows:
Line number / rev. = 50 x lead screw pitch (in mm) with 20 x evaluation (MP 12 - 15)
Line number / rev. = 100 x lead screw pitch (in mm) with 10 x evaluation (MP 12 - 15)
For angle measurement (with axis IV) rotary encoder types ?OD 250 and ROD 700 with 18.000 or
36.000 lines are available.
The cable length between transducer and TNC 150 must no1 exceed 20 m.
