● Transmission frequency
Table 2- 8
Note
If cable lengths longer than 25 m or 35 m are needed for incremental encoders, encoder
types with a 24 VDC supply voltage can be used instead.
CAUTION
To ensure error-free transmission of encoder data, do not exceed the maximum cable
lengths shown in these tables.
Encoder supply voltages
The encoder supply voltages must comply with the following specification:
