5.1.1. Wiring diagram 

NB!

Please note that input 29 is not available in FC 301. This means that only 16 positions
can be selected via digital inputs in FC 301.

5.1.2. Basic Setup 

First, check the motor connection. Please be aware that the mechanical brake control cannot be
trusted during this basic setup, therefore control brake externally from the option until setup is
finished. Also ensure that the motor can rotate freely without causing damage or injury to per-
sonal.

1.

Remove all signals to inputs . Only Input 27(coast), I8 (q-stop), I3 (HW limit) and I2 (HW
limit) must be connected and high.

2.

Select “Off” Mode

3.

Input the motor name plate data in P120-125 and activate the “Automatic Motor Adap-
tation” function in P129.

4.

Press the [Hand On] button on the FC control panel and wait for the AMA to be comple-
ted.

5.

Goto “Hand on” mode and set the frequency for a low positive value, for e3 Hz
in the reference value, please note that motor should now rotate.

6.

If the motor rotates in the wrong (negative) direction then exchange the motor phases.
