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
dif

ferent 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 T
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.

Safety Notice

This

equipment contains voltages that may be as great as 1000
volts! Electrical shock can cause serious or fatal injury
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

personnel should attempt the start-up procedure or troubleshoot
this equipment.

PRECAUTIONS

W

ARNING:

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.

ARNING:

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.

ARNING:

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

.

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.

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.

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: T

o prevent equipment damage, be certain
that the electrical service is not capable of

Group 1 Expansion Board
The Resolver to Digital Interface expansion board provides

closed loop operation for the Baldor Series 18H, 19H, 20H and
22H controls. The Resolver to Digital Interface can also be used
for PID control.

Note:

The Resolver to Digital interface is used with a motor mounted
resolver
Baldor Control. The control can then monitor and control shaft
position. The Buf
