A.3.3 Encoder cards
Note !
The encoder power supply must be adequate considering the cable length and the absorption rates as shown in table (1) at the end of this chapter.
EXP-DE-I1R1F2-ADL
Digital Incremental Encoder. This is the default card supplied with drives to control asynchronous motors in eld-
oriented ux vector mode (FOC).
