Rotating ratio molecule
P10.07 between motor and
encoder
Rotating ratio
P10.08 denominator between
motor and encoder
When encoder is not installed on the motor rotor axis, asynchronous motor vector control with encoder is
effective by setting motor and encoder rotating speed ratio (P10.07 and P10.08)
For example：if motor rotating speed is 1500RPM and encoder speed 1000RPM，set P10.07=1500，
P10.08=1000.

tuning for motor
We can run motor with open loop,

and observe r10.12 and r27.00 if they
are in the same direction, if not, then
