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 field-
oriented flux vector mode (FOC).

Management of loss of encoder signals
See table (1)
INCREMENTAL DIGITAL ENCODER (DE) PUSH-PULL/LINE DRIVER
Loss of encoder cannot be managed with single-ended versions. In this case disable the
Speed Fbk Loss.
TTL = 7V max
See table(1)
