If either the Flux Vector (A1-02 = 3) or Volts Per Hertz with Encoder (A1-02 = 1) control method is
desired, an encoder feedback board for the drive is required.
The drive can accept many types of encoder feedback. Table 1-4 shows which option board is
needed for each type of encoder.

*Accepts inputs from two encoders. Primarily used with custom software.
The most common encoder used with the drive is the Quadrature, Line Driver style
encoder. When an encoder of this type is used, a PG-X2 option board must be
mounted onto the drive. The encoder then wires to the PG-X2 option board.
Table 1-5 and Figure 1-5 show connections for the PG-X2 and some typical encoders.

For PG, Dynapar H-20, pins C, G, and J are not used.
The PG-X2 card also has a connector TA2 which provides processed PG signal output for
use by an external pulse monitor. This connection can be made according to Figure 1-5.
