Connecting the controller
For easy connection, Nanotec recommends the Discovery Board DK-NP5-48 . If you operate your controller using this Discovery Board, read chapter Connecting the NP5 controller via the Discovery Board.
Integrating the NP5
Note:
- EMC: Current-carrying cables – particularly around supply and motor cables – produce electromagnetic alternating fields.
- These can interfere with the motor and other devices. Nanotec recommends the following measures:
- Use shielded cables and earth the cable shielding on both ends over a short distance.
- Use cables with cores in twisted pairs.
- Keep power supply and motor cables as short as possible.
- Earth motor housing with large contact area over a short distance.
- Lay supply, motor and control cables separately.
Shown in the following figures is the circuit diagram of the NP5 Discovery Board, which can serve as a reference for the development of your own motherboard. You can find the pin assignment of the PCI connector strip in chapter Pin assignment.

Prepare your motherboard.
The minimum wiring varies depending on motor type and any present feedback (stepper or BLDC motor, Hall sensors/encoders). For commissioning, the connection of the voltage supply (POWER) of the motor and of the SPI cables (see also Connection SPI) is sufficient.
