3.5.1
Getting started
In order to use the positioning function, you must start the frequency inverter in
Configuration 240, 440 or 540. If required, perform a motor measurement. Several
functions will be readjusted as soon as you set up the configuration of the positioning operation. This includes the functions of the digital inputs.
Warning!
Ensure that your parameterization corresponds to the connected terminals.
For commissioning, you must select different configurations for the following cases:

Description
Motor encoder is position encoder at the
same time
Two different encoders for motor and
positioning
No motor encoder, external encoder for
positioning
Possible Configuration 30
240, 540
240, 540
440
Motor encoder is position encoder at the same time
In slip-free systems, the motor encoder can be used as position encoder at the same
time. By using one encoder for both functions, the overall costs can be reduced.
Configuration 30 = 240 | 540, motor encoder = position encoder

In the corresponding parameters, set up the properties of the encoders according to
the wiring of Encoder 1 or Encoder 2. The parameters of Encoder 2 are available
only if the corresponding extension module is connected.
Adjust parameter Actual Speed Source 766 to connected encoder.
Adjust parameter Actual Position Source 1141 to "0 - As P. 766 Actual Speed
Source" (corresponds to factory settings).
