6.4.2 Conversion of speed- and acceleration units
Speed values P201 and acceleration values P202 are specified in percent. Here data
type N2 is used (cf. Table 25).
A N2 value of x corresponds to 100*x/16384 %. Here the reference value (100 %) is
given by the maximum speed (Parameter 514) or the maximum acceleration
(Parameter 515). These are specified in rev/min (Parameter 514) and inc/sec²
(Parameter 515). System-dependently the parameters are protected over a password.
Interpretation of N2-value in physical units, see following example:

Fixed values:
Encoder resolution P505 = 1024 Inc
Maximum speed P514 = 4350 rev/min = 74240 Inc/sec
Maximum acceleration P515 = 10000 (rev/min) / sec = 170667 Inc/sec

Example:
Given:
P001 (Gearbox factor) = 50000 C4 data type
P002 (Pitch) = 40000 C4 data type
Conversion to mm/sec or mm/sec² respectively is carried out using the position factor:
