Answer: 1. The calculation of electronic gear has nothing to do with the transmission mode;
2, electronic gear ratio = encoder feedback pulse number / week command pulse number
= encoder feedback pulse frequency / command pulse frequency
3. Command pulse frequency = plc count rated frequency;
4, this way:
Electronic gear ratio = encoder resolution × motor speed (r / s) / PLC count rated frequency
5. The calculation of the pulse equivalent is related to the transmission;
6, pulse equivalent = weekly workpiece movement distance / week command pulse number
= workpiece moving speed / command pulse frequency
7. The moving speed of the workpiece is related to the transmission:
1) Screw:
Week workpiece moving distance = pitch / reduction ratio workpiece moving speed = pitch / reduction ratio × motor speed (r / s)
2) Rack drive:
Week workpiece moving distance = gear circumference / reduction ratio workpiece moving speed = gear circumference / reduction ratio × motor speed (r / s)
