Motor Parameter Descriptions
Note
These parameters are valid and active only when a user defined motor is selected. When
an Control Techniques motor is selected, the data in these registers remain at the last value
set and do not update to reflect the data of the Control Techniques motor selected.
Motor Poles
Specifies the number of magnetic pole pairs (N-S) on the motor. The supported values are 2,
4, 6, 8, 10, 12, 14 and 16 poles.
Motor Encoder Lines Per Revolution
Specifies a coefficient for determining the number of encoder lines per mechanical
revolution. The supported values are 1 to 16383. The equation for determining the total
number of encoder lines per revolution is:
nLines = n*10
where
nLines = Total number of Encoder Lines
n = Motor Encoder Lines per Rev Coefficient
x = Motor Encoder Exponent
