Only when the inverter is switched off and the
voltage supply is disconnected may the plug
be pulled out or plugged in !

Following specications apply to the encoder
interface 1 (X3A):
- Limiting frequency of input fG = 300 kHz
- internal terminating resistor Rt = 150 ohm
- 2…5 V High level at rectangular signals
Inputs
The signal and reference marking inputs can be triggered with rectangular pulses. The signal inputs must ge-
nerally be connected. The reference marking signals are only needed for the reference point approach in the
positioning operation (F5M/S).
For encoder inputs with HTL level please contact KEB!
