Encoder Interface
The PowerFlex 40P Encoder Interface can source 5 or12 volt power and
accept 5, 12 or 24 volt single ended or differential inputs.

When using 12V Encoder power, 24V I/O power, maximum output current at I/O
Terminal 11 is 50 mA.
Important: A quadrature encoder provides rotor speed and direction.
Therefore, the encoder must be wired such that the forward
direction matches the motor forward direction. If the drive
is reading encoder speed but the position regulator or other
encoder function is not working properly, remove power to
the drive and swap the A and B encoder channels or swap
any two motor leads. Drives using FRN 2.xx and greater
will fault when an encoder is incorrectly wired and E216
[Motor Fdbk Type] is set to option 5 "Quad Check".
Description
Internal power source 250 mA (isolated).
Quadrature B input.
Single channel, pulse train, or quadrature A input.
DIP switch selects 12 or 5 volt power supplied at terminals "+V"
and "Cm" for the encoder.
