Special case - linear axis
For linear axes, the following parameters differ from the parameters described in chapter Configuration of the motor and the amplifier.
0x8011:13 "Motor pole pairs"
Set this parameter to the value one.
0x8011:2E "Rated speed"
Convert the nominal velocity (vrated) to an equivalent rated speed of rotation (nrated).

The pole pitch corresponds to the half pole pair distance and is therefore multiplied by two in this equation.
Example:
- nominal velocity vrated = 544 mm/s
- Pole pitch = 16 mm

0x8011:31 "Voltage constant"
Convert the voltage constant ke as follows. Note the units.
![Special case - linear axis 3:](Images/png/10051612683__en-US__Web.png)
Example:
- Pole pitch = 16 mm
- Voltage constant ke = 6.8 V/(m/s)
