Motor feedback features
Motor encoder gear function
The drive provides motor encoder gear function for compensating of mechanical
gears between the motor shaft, the encoder and the load.
Motor encoder gear application example:
The motor encoder gear parameters
and
are set as follows:
Note:
If the motor gear ratio differs from 1, the motor model uses an estimated
speed instead of the speed feedback value.

Speed control uses the motor
speed. If no encoder is
mounted on the motor shaft,
the motor encoder gear
function must be applied in
order to calculate the actual
motor speed on the basis of the
measured load speed.
