6FC5 597–3AA20–0BP2 (01.02)
Connectable encoder types
Incremental 5 V encoders can be connected directly.
Characteristics
The encoders must meet the following requirements:
Transmission method: Differential transmission with 5 V square–wave
signalsOutput signals:
Track A as true and negated signal (U
a1
, U
a1
)
Track B as true and negated signal (U
a2
, U
a2
)
Zero signal N as true and negated signal
(U
a0
, U
a0
)
Max. output frequency: 1.5 MHz
Phase offset between
tracks A and B: 90° "30°
Current consumption: max. 300 mA
Cable lengths
The maximum cable length depends on the specifications of the encoder power supply and on
the transmission frequency.
To provide fault–free operation, make sure that the following values are not exceeded when
using preassembled interconnecting cables from SIEMENS:
