PowerFlex DC Drive Frame B Pulse Transformer Circuit Board

Pulse Transformer Board FIR2-XX Rev. “M” and Lower

1. Refer to

Table 1 -

Table 2 -

in the

Sizing Resistor Configuration

section

below for the appropriate configuration. Once you have determined the
correct configuration for your drive size, cut and remove the appropriate
sizing resistor(s) (if necessary) from the Pulse Transformer board.

Sizing Resistor Configuration

The tables below indicate the value of the designated resistor (R1…R5) when left
in place on the Pulse Transformer board, or “Remove” when the resistor should
be cut off and removed from the board. “–” indicates that there is no resistor in
this position on the Pulse Transformer board.

IMPORTANT

This procedure requires a multimeter that measures resistance to thousandths
of an ohm.
