Product Description

This instruction manual describes how to install optional Dynamic Braking (DB) kits that are used with

FlexPak™ 3000 (1.5 HP to 150 HP @ 230 VAC, 3 HP to 600 HP @ 460 VAC) and WebPak™ 3000 (1.5 HP to

75 HP @ 230 VAC, 3 HP to 150 HP @ 460 VAC) DC drives. These kits consist of separate parts that must be

mounted by the customer. See the following table to verify the kit matches your drive.

ATTENTION: Only qualified personnel familiar with the construction and operation of this

equipment and the hazards involved should install, operate, and/or service this equipment. Read

and understand this instruction manual in its entirety before proceeding. Failure to observe this

precaution could result in severe bodily injury or loss of life.

1.5 HP to 150HP @ 230 VAC, 3 HP to 300 HP @ 460 VAC Drives When the motor is running normally, the drive's normally-closed DB contactor is open and the dynamic braking resistor (dynamic braking grid) is disconnected. See figure 3. Dynamic braking slows down a rotating DC motor and its load if the motor is disconnected from the drive. It is typically initiated with a coast/DB stop command or a drive fault. When dynamic braking is initiated, the normally-closed DB contactor, shown in figure 3, closes.
PAGE 3
400 HP to 600 HP @ 460 VAC Drives The 400 HP to 600 HP @ 460 VAC drives include a DC contactor and therefore only require the resistor assembly (DB resistor). The wiring requirements are also different for these drives. When the motor is running normally, the drive's normally-open M contacts are closed and the normally-closed M contact is open. See figure 5. Note that when the drive is connected to the motor, the dynamic braking resistor (dynamic braking grid) is disconnected.

If you are using the Basic Configuration: Step 1.
PAGE 11
If you are using DB with a Motor Series Field, S1 connected to A2 with an Inverting Fault Circuit Breaker: Step 1. Follow the wiring diagram in figure 8 to connect the motor armature and the Dynamic Braking Resistor assembly to the FlexPak 3000 drive. Step 2. Remove the Removable Link (see figure 6). It is a bus section below the A2/S1 terminal and is accessed through the top of the drive as shown. At the top, the A2/S1 terminal and Removable Link are fastened with two nuts and bolts, spaced horizontally.
PAGE 12
Step 6. Connect the S2 terminal to Motor S1 terminal (see the dashed-line in figure 8). Ignore the Inverting Fault Circuit Breaker illustrated in this figure. Step 7. Route the customer-supplied wire (cable) and attach to the connections A2/S1 and Motor A2 (or Motor S1) as shown. Step 8. Connect the Series Field between the terminals Motor S1 and Motor S2. Step 9. Follow the wiring diagram in figure 5 to verify that the jumper across terminals 3 and 4 on the FIELD/ DB terminal block is installed. Step 10.
