PS1.1.4 Rotary axis pulse equivalent computing
E.g.:pulse/rev=1600,transmission ratio =1/40
Pulse equivalent=
1600
360×1/40
=177.778 (result retains up to 3 decimal places)
PS1.2 Servo driver
The pulse equivalent factory value X, Y and Z on the handle are all 400, which can be
used as a constant or change a new value to set the electronic gear ratio on the servo
motor driver. It can be reduction of a fraction.
Electronic gear ratio molecules that represent the resolution of the encoder are
found in the servo drive specification.
