Encoder supply
Warning
DIP switches 3 and 4 in ON position provide a supply voltage of 24 V to the encoder.
Therefore it is not allowed to connect a TTL encoder to the inverter if both DIP switches, 3
and 4 are in ON position.

Parameterizing the Encoder Interface

Encoder parameterization
To enable the Encoder to function correctly with the inverter, the parameters in the table
below, must be modified.

Values
Indicates the speed of the rotor. Used to check that the system is
working correctly.
Indicates the current angle of the rotor. This function is not available on
single input channel encoders.
0: No encoder
