Position actual value of the encoder

G1_XIST1 and G2_XIST1
In the factory setting, the inverter transfers the encoder position actual value with a fine
resolution of 11 bits to the higher-level control system.

The transferred encoder signal has the following properties:
● After the inverter power supply has been switched on, the encoder signal = 0.
● The higher-level control must be able to handle a counter overflow of the encoder signal.
G1_XIST2 and G2_XIST2
In G1_XIST2 or G2_XIST2, the inverter transfers different values to the higher-level control
system:
Encoder x parked
Encoder fault x
Referencing encoder x
