Mitsubishi Electric cannot assume any liability if these examples are used in real applications."
The
frequency inverters of the FR-E800EPB series are mainly intended for network
control. This article describes the method of positioning the system using the
Profinet network.
The
FR-E800E inverters have two digital inputs (DI0 and DI1) to which the
required functions can be assigned.
The
frequency inverter of the FR-E800EPB series can be extended with virtual inputs
and outputs when using the user telegram 102.

In the
first step, select the homing method from among the available:
Then it is required to define the homing speed and the acceleration and deceleration ramps:
24729 (6099h) Homing speeds
24730 (609Ah) Homing acceleration
Switch on the inverter according to the diagram below
