13.3.7.1.2 Conversion factors
The calculation of FactorPosition is only valid if servo parameter Refer-
ence Pulse Multiplier (Pn218) = 1.
FactorPosition - Factor for converting the position of user units into drive units (incre-
ments) and back.
Resolution - Number of increments per user unit
Numerator - Numerator: Electronic Gear Ratio (Pn20E) of the servo parameter
Denominator - Denominator: Electronic Gear Ratio (Pn210) of the servo parameter
Example User unit for position = 1 revolution
FactorPosition - Factor for converting the position of user units into drive units (incre-
ments) and back.
Resolution - Number of increments per user unit
Resolution = 2
20
= 1048576
Numerator - Numerator: Electronic Gear Ratio (Pn20E) of the servo parameter
Numerator = 1024
Denominator - Denominator: Electronic Gear Ratio (Pn210) of the servo parameter
Denominator = 1
Example minimum distance
MinPos - Minimum distance in rotations
Resolution - Number of increments per user unit
Resolution = 2
20
= 1048576
Numerator - Numerator: Electronic Gear Ratio (Pn20E) of the servo parameter
Numerator = 1024
Period - Minimum period
Period = 1
