DC 5 V encoder supply type DWI11A
Part number
822 759 4
Description
If you are using an incremental encoder with a DC 5 V encoder power supply, install the
DC 5 V encoder power supply option type DWI11A between the inverter and the incre-
mental encoder. This option provides a regulated DC 5 V power supply for the encoder.
For this purpose, the DC 12 V power supply for the encoder inputs is converted to
DC 5 V by means of a voltage controller. A sensor line is used to measure the supply
voltage at the encoder and compensate the voltage drop along the encoder cable.
Incremental encoders with DC 5 V encoder power supply may not be connected directly
to the encoder inputs X14: and X15:. This would cause irreparable damage to the en-
coder.
Recommendation
Use prefabricated cables from SEW for the encoder connection.

The DWI11A option is mounted on a support rail (EN 50022-35
×
7.5) in the control cab-
inet.
Technical data
NOTE
If a short circuit occurs in the sensor cable, the connected encoder may be exposed to
a voltage higher than permitted.
