Hi Matthieu,

> Number of teeth
240

> AD reduction ratio (M_1 Gear)
motor kit without housings: 12 * 48 / 20 * 240 = 6912
motor kit with housings: 12 * 50 / 20 * 240 = 7200

> Motor steps per cycle (M_1 S/Rev)
100 (for P530 motor)

> PEC following speed (Rate1)

Rate 1 has nothing to do with PEC. Rate 1 is used when you select it
from the hand controller and press east/west buttons, and it is also
used for autoguiding.
