Introduction

The Baldor controls represent the latest technology in microprocessor
based motor controls. In addition to the user programmable parameters
available in every control, many different expansion boards are available
from Baldor to further customize the control to most any application.

Expansion boards are categorized by compatibility into two groups:
Group 1 and Group 2, see Table 1-1. A board from either group may be
used alone in a control. If two boards are to be used, one board must
be from Group 1 and the other from Group 2.

Note: Using two Group 1 or two Group 2 boards in the same control is

not allowed.

Limited Warranty

For a period of two (2) years from the date of original purchase,
BALDOR will repair or replace without charge controls and
accessories which our examination proves to be defective in
material or workmanship. This warranty is valid if the unit has not
been tampered with by unauthorized persons, misused, abused, or
improperly installed and has been used in accordance with the
instructions and/or ratings supplied. This warranty is in lieu of any
other warranty or guarantee expressed or implied. BALDOR shall
not be held responsible for any expense (including installation and
removal), inconvenience, or consequential damage, including
injury to any person or property caused by items of our manufacture
or sale. (Some states do not allow exclusion or limitation of
incidental or consequential damages, so the above exclusion may
not apply.) In any event, BALDOR’s total liability, under all
circumstances, shall not exceed the full purchase price of the
control. Claims for purchase price refunds, repairs, or
replacements must be referred to BALDOR with all pertinent data
as to the defect, the date purchased, the task performed by the
control, and the problem encountered. No liability is assumed for
expendable items such as fuses.

Goods may be returned only with written notification including a
BALDOR Return Authorization Number and any return shipments
must be prepaid.

General Information 1-3

Safety Notice

This equipment contains voltages that may be as great as 1000 volts!
Electrical shock can cause serious or fatal injury. Only qualified
personnel should attempt the start-up procedure or troubleshoot this
equipment.

This equipment may be connected to other machines that have rotating
parts or parts that are driven by this equipment. Improper use can
cause serious or fatal injury. Only qualified personnel should attempt
the start-up procedure or troubleshoot this equipment.

PRECAUTIONS

WARNING: Do not touch any circuit board, power device or

electrical connection before you first ensure that power has
been disconnected and there is no high voltage present
from this equipment or other equipment to which it is
connected. Electrical shock can cause serious or fatal
injury. Only qualified personnel should attempt the start-up
procedure or troubleshoot this equipment.

WARNING: Be sure that you are completely familiar with the

safe operation of this equipment. This equipment may be
connected to other machines that have rotating parts or
parts that are controlled by this equipment. Improper use
can cause serious or fatal injury. Only qualified personnel
should attempt the start-up procedure or troubleshoot this
equipment.

1-4 General Information

WARNING: Be sure the system is properly grounded before

applying power. Do not apply AC power before you ensure
that all grounding instructions have been followed.
Electrical shock can cause serious or fatal injury.

WARNING: Do not remove cover for at least five (5) minutes

after AC power is disconnected to allow capacitors to
discharge. Dangerous voltages are present inside the
equipment. Electrical shock can cause serious or fatal
injury.

WARNING: Improper operation of control may cause violent

motion of the motor shaft and driven equipment. Be certain
that unexpected motor shaft movement will not cause injury
to personnel or damage to equipment. Peak torque of
several times the rated motor torque can occur during
control failure.

WARNING: Motor circuit may have high voltage present

whenever AC power is applied, even when motor is not
rotating. Electrical shock can cause serious or fatal injury.

Caution: To prevent equipment damage, be certain that the

electrical service is not capable of delivering more than the
maximum line short circuit current amperes listed in the
appropriate control manual, 230 VAC, 460 VAC or 575 VAC
maximum per control rating.

Board Installation

This section describes the Expansion Board installation procedure.

Caution: Before you proceed, be sure to read and become

familiar with the safety precautions at the beginning of this
manual. Do not proceed if you are unsure of the safety
precautions described. If you have any questions, contact
BALDOR before you proceed.

1. Remove the expansion board from the shipping container.

2. Remove all packing material from the board.

Caution: Be sure all packing materials are removed from the

board. Conductive foam may be present on the connectors
to prevent static build up during shipping. This can prevent
proper circuit operation.

If you are installing only one board, refer to the “Single Expansion Board
Installation” procedure. If you are installing two expansion boards (or a
second board) refer to the “Dual Expansion Board Installation”
procedure.

AC Controls

(For all 15H Inverter, 21H Line Regen Inverter, 18H Vector, 22H Line
Regen Vector and 23H Servo).

Single Expansion Board Installation

Procedure:

1. Be sure drive operation is terminated and secured.

2. Remove all power sources from the control.

3. Wait at least 5 minutes for internal capacitors to discharge.

4. Remove the four (4) Phillips head screws (

1

/4 turn) that secure the
control cover. (For A & B size, remove four screws that secure the
cover. On floor mounted G size enclosures, open the enclosure
door).

5. Remove the control cover.

6. Slide the expansion board male connector into the female
connector of the control board. See Figure

3-1.

7. Securely mount the expansion board to the sheet metal mounting
plate using the #6 screws provided in the installation hardware.
See Figure 3-2.

8. The mechanical installation of the expansion board is now
complete. Refer to Section 4 of this manual and configure the
jumpers as desired. Also complete the wiring before you proceed
to step 9.

9. When complete, install the control cover using the four (4) Phillips
head screws (

1

/4 turn). (For A & B size, install four screws that
secure the cover. On floor mounted G size enclosures, close the
enclosure door).

10. Restore all power sources to the control.

11. Restore drive operation.
