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.

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.
