9.1 Resolution of the system
In order to determine the resolution, the relationship between measuring wheel and motor must
be considered.
In the following, the resolution is taken into consideration:
Measuring wheel parameters:
• Encoder constant [inc/rev]
• Measuring wheel constant [units/rev]
nits/umdr] constant[u wheel measuring
nc/umdr] constant[i encoder
] [inc/units resolution encoder
=
Drive parameters:
• Feed constant [units/r]
• Gearbox factor numerator
• Gearbox factor denominator
mdr] nt[units/u feedconsta * r denominato factor gearbox
numerator factor gearbox
s] [umdr/unit resolution motor
=
Total resolution:
