224 Parameters
90
90 Enc module sel Activation of encoder/resolver interfaces. See also section
Encoder support on page 62 .
90.01 Encoder 1 sel Activates the communication to optional encoder/resolver
interface 1.
Note: It is recommended that encoder interface 1 is used
whenever possible since the data received through that
interface is fresher than the data received through interface 2.
On the other hand, when position values used in emulation
are determined by the drive software, the use of encoder
interface 2 is recommended as the values are transmitted
earlier through interface 2 than through interface 1.
