The NP5 is used to control stepper and BLDC motors and is designed for use under the approved Environmental conditions.
The controller must be connected to motors via a PCI-format connector strip and a suitable motherboard. The system boundary of the controller ends at the PCI connector strip.
Any other use is considered unintended use.

EU directives for product safety
The following EU directives were observed:
- RoHS directive (2011/65/EU, 2015/863/EU)
Other applicable regulations
In addition to this technical manual, the following regulations are to be observed:
- Accident-prevention regulations
- Local regulations on occupational safety
All notices are in the same format. The degree of the hazard is divided into the following classes.
Emphasis in the text
The following conventions are used in the document:
Text set in bold indicates cross references and hyperlinks:
- The following bits in object 6041h (statusword) have a special function:
- A list of available system calls can be found in chapter System calls in a NanoJ program.
Text set in italics marks named objects:
- Read the installation manual.
- Use the Plug & Drive Studio software to perform the auto setup.
- For software: You can find the corresponding information in the Operation tab.
- For hardware: Use the ON/OFF switch to switch the device on.
A text set in
Courier marks a code section or programming command:
- The line with the
od_write(0x6040, 0x00, 5 );command has no effect.
- The NMT message is structured as follows:
000 | 81 2A
A text in "quotation marks" marks user input:
- Start the NanoJ program by writing object 2300h, bit 0 = "1".
- If a holding torque is already needed in this state, the value "1" must be written in 3212h:01h.
Numerical values are generally specified in decimal notation. The use of hexadecimal notation is indicated by a subscript h at the end of the number.
The objects in the object dictionary are written with index and subindex as follows:
Both the index as well as the subindex are specified in hexadecimal notation. If no subindex is listed, the subindex is 00h.
Example: Subindex 5 of object 1003h is addressed with
1003h:05h, subindex 00 of object 6040h with
The numbering of individual bits in an object always begins with the LSB (bit number 0). See the following figure, which uses data type UNSIGNED8 as an example.
Counting direction (arrows)
In figures, the counting direction is always in the direction of an arrow. Objects
60C6h depicted as examples in the following figure are both specified as positive.
