Notes for the status word:
 Bit0–Bit9 have the same meaning in different control modes. When the master station sends the control word
6040h, the drive gives certain status feedback;
 Bit10, Bit11, Bit12 and Bit13 are specific to different control modes;
 Bit14 and Bit15 are defined by the manufacturer.
4. Common conversion factor
The user units are usually different from the motor units in drive control. CiA402 device conventions provide a group
of conversion factors to make conversion between user units and motor units.
The default motor units of SPS-NE are as follows:
 Motor displacement unit: p (pulse)
 Motor speed unit: rpm (revolutions per minute)
 Motor acceleration unit: rpm/ms (10 rpm/ms means the acceleration amplitude is 10 rpm in 1 ms)
The commonly used user units are as follows:
 Load displacement unit: mm
 Load speed unit: mm/s

Load acceleration unit: mm/s

(1) Position factor (6093h)
Position factor refers to the motor displacement (unit: p) corresponding to the load displacement of one user unit.
Position factor consists of the numerator 6093-1h and the denominator 6093-2h, through which a relation between
the load displacement (user unit) and the motor displacement (motor unit) can be formulated as below:
Position factor (6093h) =
Numerator of position factor (6093 −1h)
Denominator of position factor (6093 −2h)
Motor displacement = Load displacement (user) × Position factor
