Encoder Option Card Usage Appendix D
In the Motor Feedback configuration, enter the resolution of the encoder used.
Encoder Interface
The incremental encoder option card can source 5 or 12 volt power and accept 5,
12 or 24 volt single ended or differential inputs. See
Appendix B for ordering
information.
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 A (NOT) encoder channels or swap any two motor
leads.

Output DIP switch selects 12 or 5 volt power supplied at terminals “+V” and “Cm”
for the encoder.
(1) When using 12V Encoder power, 24V I/O power, maximum output current at I/O Terminal 11 is 50 mA.
(2) If Encoder requires 24V power, it must be supplied by an external power source.
