Description of Functions
The table below gives you an overview of the data used in this calculation
and their meaning. You will find the machine data (MD) assignments under
"Function parameters".
Sym-
If unusual numbers of pulses or steps result, the encoder with the next-higher
number of pulses or steps should be selected.
Encoder and
It is only permissible to mount rotary encoders onto stepper motors in the
Stepper Motor
ratio 1:1. It is not appropriate to have an encoder resolution which is higher
than the pulse resolution of the motor.
