The 'Min position accuracy' field is located on the Main form as
shown. It is an angle for rotary mechanism, and a length for linear
mechanisms.
The 'Min position accuracy' field is used for:
- Checks that if the combined backlash of all compenents in the
drive chain is larger than the load minimum position accuracy
value, a message appears in System Check. Products with backlash
include gearboxes, rack & pinion, etc.
- When selecting a gearbox in the Gearboxes database, use either
the standard or reduced backlash filter ('jt2std' or jt2red'), and
the 'Req_jt2' variable. 'Req_jt2' is the min position accuracy at
the load translated to the gearbox output. Therefore 'jt2std <=
'Req_jt2' means the gearbox backlash must be <= the minimum
required application backlash at the gearbox output.
- On the Main form at the motor stage, display the minimum
encoder resolution required to achieve the min position accuracy at
the load.
