PowerFlex DC Drive Frame C Pulse Transformer Circuit Board
Step 4: Configure the New
Pulse Transformer
Board
The Pulse Transformer circuit board must be configured to match the drive size
(armature output current and HP rating). The steps required to complete the
configuration are different based on the revision code of the board. See either,
Pulse Transformer Board FIR3-XX Rev. “L” and Lower
below, or Pulse
Transformer Board FIR3-XX Rev. “M” and Higher on page 13.
Pulse Transformer Board FIR3-XX Rev. “L” and Lower
1. Cut and remove the appropriate sizing resistor(s) (if necessary) from the
Pulse Transformer board based on the drive size. Refer to Table 1 -
or Ta ble
2 - in the Sizing Resistor Configuration section on page 11 for the
appropriate configuration.
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 indicate “Remove” when the resistor
should be cut off and removed from the board. “–” indicates that this resistor is
not contained on the Pulse Transformer board for the designated drive size.

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