input
The plug connection X5 of the CDD3000-HF drive controller is designed
alternatively to provide the
• incremental encoder simulation or
• incremental master encoder input
function. The signals are isolated from the control electronics.
3.8.1 Encoder
simulation
Encoder simulation forms incremental encoder-compatible pulses from
the position of the rotary encoder connected to the motor. Accordingly,
pulses are delivered in two 90° offset signals A and B as well as a zero
pulse R.

Step Action Comment
1
Define the function of the connection:
• Encoder simulation 3.8.1
• Master encoder input 3.8.2
2
Specify the wire according to the
application. A wire cross-section of less than
0.14 mm² should not be chosen. The
differential signals (A, B and R) must be
connected to twisted pair wires.
