6.7.1 Incremental encoder with TTL level at X8
On X8, only incremental encoders with TTL level can be operated. Wiring
diagram and pin assignment of X8 are described in chapter ”Wiring of the
basic device” → ”Wiring of the feedback system”.
ƒ C0025 = 100. In addition, you have to set the number of increments in
C0420.
ƒ C0025 = 110, 111, 112 or 113. The number of increments (512, 1024,
2048 or 4096) is automatically set.
The incremental encoder obtains its supply voltage from the drive controller.
 Stop!
If the supply voltage is too high, it may destroy the incremental
encoder.
Use C0421 to set the supply voltage V
CC
(5 V) for the incremental encoder to
compensate, if required, a voltage drop on the incremental encoder cable.

6.7.2 Incremental encoder with HTL level at X9
On X9, incremental encoders withHTL level can be operated. Wiring diagram
and pin assignment of X9 are described in chapter ”Wiring of the basic
device” → ”Wiring of the feedback system”.
ƒ C0025 = 101. In addition, you have to set the number of increments in
C0420.
The incremental encoder must be operated with an external supply voltage.
C0421 has no influence.
ƒ Incremental encoders with HTL level require DC 8 ... 30 V supply
voltage. Please observe the information of the manufacturer.
