Quick Start Guide
Overview
If you are an experienced user of Baldor controls, you are probably already familiar with
the keypad programming and keypad operation methods. If so, this quick start guide has
been prepared for you. This procedure will help get your system up and running in the
keypad mode quickly and will allow motor and control operation to be verified. This
procedure assumes that the Control, Motor and Dynamic Brake hardware are correctly
installed (see Section 3 for procedures) and that you have an understanding of the
keypad programming & operation procedures. It is not necessary to wire the terminal
strip to operate in the Keypad mode (Section 3 describes terminal strip wiring
procedures). The quick start procedure is as follows:
1.
Read the Safety Notice and Precautions in section 2 of this manual.
2.
Mount the drive.
3.
Connect AC power. Refer to Section 3 “AC Power Connections”.
4.
Plug in the keypad. Refer to Section 3, “Optional Remote Keypad Mounting”
procedure.
Check of Electrical Items
CAUTION: After completing the installation but before you apply power, be
sure to check the following items.
1.
Verify AC line voltage at source matches the SmartMotor rating.
2.
Inspect all power connections for accuracy, workmanship, tightness and
compliance to codes.
3.
Verify SmartMotor is grounded to earth ground.
4.
Check all signal wiring for accuracy.
5.
Be certain all brake coils, contactors and relay coils have noise suppression.
This should be an R-C filter for AC coils and reverse polarity diodes for DC
coils. MOV type transient suppression is not adequate.
WARNING: Make sure that unexpected operation of the motor shaft during start
up will not cause injury to personnel or damage to equipment.
Check of Motor and Coupling
1.
Verify freedom of motion of the motor shaft.
2.
Verify that motor couplings are tight without backlash.
3.
Verify the holding brakes, if any, are properly adjusted to fully release and set to
the desired torque value.
Temporary Application of Power
MN750
1.
Check all electrical and mechanical connections before applying power to the
SmartMotor.
2.
Verify that control logic inputs at the J1 connector are proper.
3.
Temporarily apply power and observe that the bus power indicator is on or that
the optional keypad display is on (if Keypad is connected). If this indication
does not occur, check all connections and verify input voltage. If fault indication
occurs, refer to the troubleshooting section of this manual.
4.
Disconnect all power from the SmartMotor.

Minimum Required Parameter Settings and Control Set-up Checklist
If you are familiar with programming Baldor controls continue with the following steps. If
not, proceed to the programming section of this manual before applying power to the
drive.
Note: This list is the minimum program parameters required for operation of the
control for initial start-up.
1.
Be sure drive operation is terminated and secured.
2.
Remove all power sources from the motor. Wait at least 5 minutes before
proceeding to step 3.
3.
Remove cover. Remove the four (4) screws that secure the control cover and
remove cover.
4.
Connect the optional Keypad to the Keypad Connector (Figure 3-1). Run the
keypad wires through the conduit to motor case.
5.
Install the control cover. Place the cover on the control and install & tighten the
four (4) screws that secure the control cover.
6.
Apply power to the SmartMotor.
7.
Set the operating mode at the Level 1 Input block Operating Mode parameter.
8.
Set the desired minimum output frequency by setting the Min Output Freq
parameter in the Level 2 Output Limits block.
9.
Set the desired maximum output frequency by setting the Max Output Freq
parameter in the Level 2 Output Limits block.
10. If the desired peak current limit is different than presently set the PK Current
Limit parameter in the Level 2 Output Limits block.
11. If using an external analog command, check ANA CMD Select parameter to
verify the SmartMotor is ready to accept your analog command signal.
12. Set the desired Volts/Hertz ratio by setting the V/HZ Profile Parameter in the
Level 2 V/HZ and Boost Block.
13. If the load is a high initial starting torque type, the Torque Boost parameter in
the Level 1 V/HZ and Boost Block may need to be increased. Also, the ACCEL
TIME #1 parameter in the Level 1 ACCEL/DECEL Rate block may need to be
increased.
14. Set the date and time parameter in the Diagnostic Info screens.
15. Select and program additional parameters to suit your application.

General Information
Overview
The Baldor SmartMotor is an integrated industrial motor and inverter control that is
simple and fast to install. Using Baldor SmartMotor will give you:
Designed Motor and Control Compatibility - By integrating the control electronics and
the motor during the design and manufacturing process, we achieve better performance
and compatibility. Just size the drive to the load characteristics. We even make sizing to
the load characteristics easy by providing a Matched Performance curve.
Fewer Wiring Mistakes - Let Baldor pre-wire the motor to the control and eliminate one
major wiring mistake potential. Just connect power and control wiring (if necessary) and
you’re ready to run. In addition, you save the cost of the wire and conduit between the
motor and control. That is just another way Baldor adds value to our products. Baldor
saves you money and eliminates expensive errors.
Fewer Programming Errors - How many hours have been spent trying to program the
motor control to the motor characteristics? The Baldor SmartMotor is a factory
assembled motor drive. Baldor pre-programs all the required motor setup adjustments.
If you prefer, you can still access all the normal inverter adjustments through the optional
keypad or standard RS-485 port to custom tailor your particular application.
Eliminate Reflected Wave Voltage - You may know this phenomenon by other names
such as standing wave or voltage ring-up. If the distance between the motor and control
is long and the switching frequency is just right, a standing wave can form between the
motor and control. These standing waves can increase the voltage at the motor terminals
causing the motor to fail prematurely. Locating the control near the motor can keep this
problem from occurring. Until now it was not always possible to prevent long motor to
control distances. The distance between the Baldor SmartMotor control and motor is
measured in inches not feet.
Eliminate Panel Space - Trying to retrofit an existing fixed speed application to
incorporate variable speed control and don’t have the panel space to mount a motor
control? Not a problem with the Baldor SmartMotor. Since the control electronics are
integrated into the motor design you only need to supply a power disconnect. In many
cases you can probably use the existing wiring and conduit running to the motor location.
Power Module - The Baldor SmartMotor uses a definite purpose integrated power
module specifically designed for Baldor SmartMotor use. Environmental heating is the
most damaging element for motor and control design. By using a definite purpose power
module Baldor reduces the potential for damaging heat generated from the motor or
control. Simply taking a micro inverter and mounting it to a motor will not allow for cost
effective integration. Premature failure has not been eliminated because the motor
control electronics were not designed for high ambient temperature operations.
Patented TEFC Control Electronics Cooling - By using the motor shaft mounted
cooling fan we can offer smaller package sizes and cost effective cooling for the motor
and control. This patented design has been refined over several generations of products
and the result can be seen on the Baldor SmartMotor.
High Efficiency Inverter Duty Motor Designs - Building on Baldor’s many years of
experience in designing and manufacturing inverter duty motors, the Baldor
SmartMotor incorporates the same design features as offered in our industry standard
inverter duty motor product line. Some of the many features include Class H insulation
system, 200oC Inverter Spike Resistant (ISR) magnet wire, low loss motor lamination,
and precision rotor balance.
DC Bus Powered Logic Supply - The control circuitry is powered from the control’s
internal DC Bus for greater noise immunity and increased reliability. Additionally the
power-loss-ride-through capability is increased when compared to designs using AC
powered logic. The Baldor SmartMotor can be operated directly from a DC source
such as found in automotive air conditioners and other battery powered devices.

Description
PRESET
SPEEDS
7 preset speeds allow selection of 7 predefined motor operating frequencies.
Each speed may be selected using external switches connected to J1-7, J1-8 and J1-9.
For motor operation, a motor direction command must be given along with a preset speed command.
ACCEL/DECEL
RATE
Accel time is the number of seconds required for the motor to increase at a linear rate from 0Hz to the
frequency specified in the “Maximum Output Frequency” parameter in the Output Limits Level 2 blocks.
Decel time is the number of seconds required for the motor to decrease at a linear rate from the frequency
specified in the “Maximum Output Frequency” parameter to 0Hz.
S-Curve is a percentage of the total Accel or Decel time and provides smooth starts and stops.
Figure 4
2 illustrates how motor acceleration is changed using a 40% S
Curve.
4-2
S-Curve.
S and 100% represents ffull “S”
S with no linear segment.
0% represents no “S”
Example: Maximum Output Frequency=100 Hz; Preset Speed = 50Hz, Accel Time=10 Sec.
In this example, motor will be at speed 5 seconds after commanded because preset is half the max speed.
Note: Accel Time #1, Decel Time #1 and S-Curve #1 are related. Likewise, Accel Time #2, Decel Time
#2 and S-Curve #2 are related. These relations can be used to control any Preset Speed or
External S
eed Command (Pot).
Speed
Note: Since the motor uses rotor slip to produce motor torque, the motor speed may not change in a
linear manner with the applied frequency. Accel, Decel and S-Curve values may be adjusted for
your application.
application
Note: If faults (motor trips) occur during rapid Accel or Decel, selecting an S-curve may eliminate the
faults without affecting the overall ramp time.
Jog Speed changes motor speed to the preset value for jog mode. To cause motor to operate at Jog Speed
the FWD or REV key must be pressed
ressed or external command Forward (J1-5) or Reverse (J1-6). The motor
will run at jog speed until FWD or REV key is released or external command signal is removed.

KEYPAD SETUP
Stop Key -
Allows keypad “STOP” key to initiate motor stop during remote or serial operation (if Stop key is
set to Remote ON). If active, pressing “STOP” automatically selects Local mode and initiates
the stop command.
Stop Mode - Selects if the Stop command causes the motor to “COAST” to a stop or “REGEN” to a stop. In
g and frequency
q
y to the motor is reduced at a rate set by
y “Decel Time”.

Run FWD -
Makes the keypad “FWD” key active in Local mode.
Run REV -
Makes the keypad “REV” key active in Local mode.
Jog FWD -
Makes the keypad “FWD” key active in Local Jog mode.
Jog REV -
Makes the keypad “REV” key active in Local Jog mode.
Ten “Operating Modes” are available:
(Wiring diagrams are shown in Section 3 “Operating Mode & Connection Diagram Examples”).
Keypad; Allows keypad commands to control motor operation.
#1 2WIRE/7 SPD; Allows 2 wire control and 7 preset speed settings (plus Analog Command Input).
#2 2WIRE/TRIP; Allows 2 wire control and External Trip input.
#3 2WIRE/3 SPD; Allows 2 wire control, Ramp selection, and 3 preset speed settings (plus Analog
Command Input). (Ramp selects Accel/Decel/S-Curve associated group #1 or 2 preset values. Open
selects group #1 and closed selects group #2).
#4 3WIRE/3SPD; Allows 3 wire control and 3 preset speed settings (plus Analog Command Input).
#5 3WIRE/TRIP; Allows 3 wire control and External Trip input.
#6 2WIRE/EPOT; Allows 2 wire control and “EPOT” (electronic digital pot that allows selection of Analog
input or Preset Speed #1).
#7 3WIRE/EPOT; Allows 3 wire control and “EPOT” (electronic digital pot that allows selection of Analog
input or Preset Speed #1).
PROF RUN-REM; Profile Run; Operating in the Remote mode.
PROF RUN-LOC; Profile Run; Operating in the Local mode.
ANA CMD Select - Selects the external speed reference to be used. The most simple method of speed control
is to select POTENTIOMETER and connect a 5kW pot to J1-1, J1-2, and J1-3. If long distance is required
between the external speed control and the SmartMotor, the 0-20mA or 4-20mA selections should be
considered. Current loop allows long cable lengths without attenuation of the command signal.
ANA CMD Inverse - “Off” will cause a low input voltage (e.g. 0VDC) to be a low motor speed command and a
maximum input voltage (e.g. 10VDC) to be a maximum motor speed command. “ON” will cause a low
input voltage (e.g. 0VDC) to be a maximum motor speed command and a maximum input voltage (e.g.
10VDC) to be a low motor speed command.
ANA CMD Offset - Provides an offset to the Analog Input to minimize signal drift. For example, if the minimum
speed signal is 1VDC (instead of 0VDC) the ANA CMD Offset can be set to -10% so the minimum voltage
input is seen by SmartMotor as 0VDC.
ANA CMD Gain - Provides an adjustment value to scale the speed reference signal. For example, if the
maximum speed signal is 9VDC (instead of 10VDC) the ANA CMD Gain can be set to 111% so the
maximum voltage input is seen by SmartMotor as 10VDC.
ANA CMD Filter - Adjusts the amount of filtering of the speed reference signal. A value of 0 provides no noise
rejection but fastest response to follow the Speed Reference. A value of 6 provides maximum filtering for
best noise rejection but less response to speed reference signal changes.

Description
V/HZ AND BOOST
CTRL BASE FREQ - Sets the point on the V/Hz profile where the output voltage becomes constant regardless
of further increases in output frequency. This is the output frequency that the motor
changes from constant torque (or variable torque) to constant horsepower operation.
TORQUE BOOST - This value can be changed to increase or decrease the motor starting torque, This boost
adjustment changes the output voltage from the normal value (defined by the V/Hz profile)
by increasing or decreasing the starting output voltage by fixed values. Increasing the
boost value may cause the motor to overheat. If adjustment is required, apply maximum
load to the motor shaft. Increase the Torque Boost value until the shaft just starts to
rotate.
DYNAMIC BOOST - This value can be changed to increase or decrease the motor running torque, This
boost adjustment changes the output voltage from the normal value (defined by the V/Hz
profile) by increasing or decreasing the output voltage per output frequency ratio.
SLIP COMP ADJ - This parameter allows adjustment for varying load conditions during normal operation.
The Slip Comp Adjustment sets the maximum variation of output frequency under varying
load conditions. As the motor current increases toward 100% of Motor Rated Amps, the
control will increase the output frequency to compensate for motor slip.
V/HZ Profile -
Option
This parameter defines how much voltage will be applied to the motor in various segments
of the output frequency range. The V/Hz values can adjust the amount of available torque
from the motor at various speed points. 5 options are available: (See Figure 4-3)
Description
Linear -
Used for constant torque applications such as conveyor systems.
9 Points -
Factory set for optimum motor performance.
33% Square Law- Variable torque application preset profile.
67% Square Law- Variable torque application preset profile.
100% Square Law- Variable torque application preset profile.
MAX Output Volts - Sets the maximum output voltage available to the motor. In some cases, this value along
with the CTRL Base Frequency can be adjusted to provide a wider constant torque range
or wider constant horsepower speed range than is normally available from the motor.

OUTPUT LIMITS
MIN Output Frequency - Minimum value in Hz of the frequency to be applied to the motor.
MAX Output Frequency - The maximum output frequency to the motor. This value may be exceeded slightly if
Slip Compensation is active.
PK Current Limit - The maximum output current to the motor. Values less than 100% are useful to limit motor
torque that may damage driven equipment. Values of 101 to 150% can be sustained for 60 seconds and
values between 151% and 200% can be sustained for 3 seconds.
PWM Frequency - The frequency that the output transistors are switched. PWM should be as low as possible
to minimize stress on the output transistors and motor windings. PWM frequency is also referred to as
“Carrier” frequency.
CUSTOM UNITS
Decimal Places - The number of decimal places of the Output Rate display on the Keypad display. This value
will be automatically reduced for large values.
Value at Speed - The desired Output Rate value per motor RPM. The Output Rate is the number to the left of
the “/” and the motor RPM is the number to the right of the “/”. See also, Units of Measure.
Units of Measure - The customized units of measure that are displayed with the Output Rate. To set the units
text, first select the character by using the SHIFT key and use the and
keys to scroll through the
available character choices. If the desired character is not shown on the first line of the display, use the
SHIFT key to move the cursor to the and
arrow on the far left of the display. Once the cursor is on the
Up/Down arrow special character, the arrow keys are used to select the character on the top line of the
display. Then select the next character. See also, Value at Speed.
PROTECTION
External Trip OFF - External Trip is Disabled.
ON - If Operating Mode (Level 1 INPUT block parameter) is set to 2 Wire/Trip or 3 Wire/Trip and a normally
closed contact at J1-9 is opened, an External Trip fault is generated and the SmartMotor will shut down.
PWM vs TEMP OFF - PWM vs TEMP disabled.
ON - If temperature of the control is too great, PWM frequency will automatically be reduced.
FOLDBACK PREVENT OFF - FOLDBACK PREVENTION disabled.
ON - Accel/Decel rate will automatically be extended to prevent overcurrent trips during rapid acceleration
or overvoltage trips during rapid deceleration.
MISCELLANEOUS
Restart Auto/Man Manual - If a fault occurs, the SmartMotor must be manually reset to resume operation.
Automatic - If a fault occurs, the SmartMotor will automatically reset to resume operation.
Restart Fault/Hr - The maximum number of automatic restart attempts before requiring a manual restart. After
one hour without reaching the maximum number of faults or if power is turned off and on again, the fault
count is reset to zero.
Restart Delay - The amount of time allowed after a fault condition for an automatic restart to occur. Useful to
allow sufficient time to clear a fault before restart is attempted.
Factory Settings - Restores factory settings for all parameter values. Select YES and press “ENTER” key to
restore factory parameter values. The keypad Display will show “Operation Done” then return to “NO”
when completed.

SECURITY
CONTROL
Security State Off - No security Access Code required to change parameter values.
Local - Requires security Access Code to be entered before changes can be entered using the Keypad.
Serial - Requires security Access Code to be entered before changes can be entered using the RS 485
link.
Access Timeout - The time in seconds the security access remains enabled after leaving the programming
mode. If you exit and go back into the program Mode within this time limit, the security Access Code does
not have to be re-entered. This timer starts when leaving the Program Mode (by pressing Display etc.).
Access Code - This code allows only those knowing the code to change secured parameter data.
Note: Please record your access code and store it in a safe place. If you cannot gain entry into parameter
values to change a protected parameter, please contact Baldor. Be prepared to give the 5 digit code
located on the lower right side of the Keypad Display at the Security Control Access Code parameter
prompt.
MOTOR DATA
Motor Voltage - The rated voltage of the motor (listed on the rating plate). This is a view only parameter and
cannot be changed.
Motor Rated Amps - The rated current of the motor (listed on the rating plate). If the motor current exceeds
this value for a period of time, an Overcurrent fault will occur. This value can only be decreased from the
Rated Amps value.
Motor Rated SPD - The rated speed of the motor (listed on the rating plate). If Motor Rated SPD = 1750 RPM
and Motor Rated Freq = 60 Hz, the Keypad Display will show 1750 RPM at 60 Hz but 850 RPM at 30Hz.
This is a view only parameter and cannot be changed.
Motor Rated Freq - The rated frequency of the motor (listed on the rating plate). This is a view only parameter
and cannot be changed.
Motor Mag Amps - The motor magnetizing current value (listed on the rating plate). Also called no load
current. This is a view only parameter and cannot be changed.
BRAKE ADJUST
Resistor Ohms - The resistance value of the external dynamic braking resistor in ohms. Preset to 0 (no
braking). Refer to dynamic braking manual or call Baldor for additional information.
Resistor Watts - The power rating of the external dynamic braking resistor in watts. Preset to 0 (no braking).
Refer to dynamic braking manual or call Baldor for additional information.
DC Brake Voltage - The voltage level that will be applied to the motor windings during DC injection braking.
Higher percentage braking levels will cause the motor to have more braking torque available for stopping.
For applications that require frequent Stops and Starts DC injection braking will cause additional motor
heating. The maximum DC voltage available =1.414(Max Output Volts*).
* Max Output Volts is a Level 1 V/Hz Block parameter.
DC Brake Freq - The output frequency at which DC injection braking begins. If this is less than the motor
operating frequency, after a stop or reverse command the motor speed will decrease by the Decel Time
parameter. When motor speed is reduced to a frequency equal to the DC Brake Freq DC voltage will be
supplied to the motor for the amount of time specified by Stop Brake Time. If immediate DC injection
braking is desired, this parameter should be set to a value greater than the motor operating frequency.
Brake on Stop - Turns on DC injection braking after a stop command.
Brake on Reverse - Turns on DC injection braking after a command to change motor rotation direction.
Stop Brake Time - The amount of time the DC injection braking is applied after a stop command if Brake on
Stop parameter = ON. If braking starts at a frequency less than set by the DC Brake Freq parameter,
braking time is determined by the following formula:
Output Freq at Braking
Brake Time + Stop Brake Time
DC Brake Freq
ǒ
Ǔ
Brake on Start - Allows DC Injection Braking at the beginning of a run command to ensure the motor shaft is
not rotating. DC Injection Braking will automatically turn off and the motor will be commanded to accelerate
to speed after the time specified by the Start Brake Time parameter.
Start Brake Time - The amount of time the DC injection braking is applied if Brake on Start parameter = ON.
Start Brake Time should be just long enough to ensure the motor is not rotating at start up. Additional
motor heating will occur in applications that require frequent starts and stops.

PROCESS
CONTROL
Follow IN/OUT - Set the ratio of the Master to the Follower. Fractional ratios such as 0.5:1 are entered as 1:2.
SKIP FREQUENCY
Skip Frequency #1, #2, and #3 - Three frequency bands can be specified. Each value is the mid point of the
frequency band to skip. This feature is useful to eliminate critical machine speeds that cause unwanted
vibrations.
Encoder Lines - Enter the number of pulses per revolution of the master encoder for follower operation. Is also
used to set the master pulse rate for downstream follower controls.
Skip Band #1, #2, and #3 - The Skip Band value is the bandwidth of the skip frequencies. Used with the Skip
Frequency parameter to completely specify the 3 bands. Example, Skip Freq = 20 Hz, Skip Band = 5 Hz.;
the actual frequencies to skip are 15 Hz to 25Hz. Two additional bands may be specified.
SYNCHRO STARTS
Synchro–Starts - Select if the motor speed synchronization is disabled “OFF”, on for automatic starts after a
fault condition “Restarts Only”; or on for “All Starts” (after a fault, after loss of input power, or a run
command is issued). The Synchro Start feature is desirable for applications in which the motor shaft is
turning when the motor is commanded to start.
Sync Start Freq - Set Synchro Start to begin scanning at a specified frequency or at the Max motor frequency.
Scanning will start at this frequency and end at 0 Hz.
Sync Scan V/F - Set the Synchro Start Volts/Hz ratio as a percentage of the Max Output Volts/CTRL Base
Freq parameters of the Level 1 V/Hz and Boost block. The factory setting provides enough power to just
magnetize the rotor and should be adequate. If too high, SmartMotor may fault on Overcurrent.
Sync Setup Time - Sets the time allowed to ramp the output voltage from 0 volts to the voltage that
corresponds to the Sync Start Freq. Only applies if Synchro Start is active. If the Synchro Start feature is
not operating quickly enough, this time may be decreased. Otherwise the factory setting should be
adequate.
Sync Scan Time - Used to eliminate false Synchro Starts and is the time allowed for frequency scanning. Sets
the time allowed to scan from the Sync Start Freq to 0 Hz. Should be set as great as possible to eliminate
false Synchro Starts.
Sync V/F Recover - Sets the ramp time to increase the output voltage from the voltage that corresponds to the
Sync Start Freq to the normal motor output voltage. Should be low enough to minimize Synchro Start time
without causing a fault on Overcurrent.
Sync Direction - Selects if the Synchro Start will begin scanning for motor rotational frequency in forward only,
reverse only, or both forward and reverse. If the application requires only one direction of motor rotation,
then setting Sync Direction to that direction only will reduce detection/sync time.
PROFILE RUN
NUMBER OF CYCLES - A profile consists of 0 to 7 predefined run conditions and each extends for a defined
number of seconds.
RP RESTART MODE - If the profile is interrupted (lost power or stopped), Restart from beginning of profile
after interrupt or Continue from point of interrupt.
SPD#1-7 CURVE/DIR - Seven (7) conditions can be defined using ACCEL/DECEL curve 1 or 2 and FWD or
REV motor shaft travel.
PROFILE TIME #1-7 - The duration of each condition in seconds.

Section 3
Receiving & Installation
Receiving & Inspection
Overview
Location and Mounting
The SmartMotor is thoroughly tested at the factory and carefully packaged for
shipment. When you receive your drive, there are several things you should do
immediately.
1.
Observe the condition of the shipping container and report any damage
immediately to the commercial carrier that delivered your control.
2.
Verify that the part number of the control you received is the same as the part
number listed on your purchase order.
3.
If the control is to be stored for several weeks before use, be sure that it is
stored in a location that conforms to published storage specifications. (Refer to
Section 6 of this manual).
This section describes the proper mounting and wiring procedure of the Baldor
SmartMotor. If problems arise after installation, please refer to the Diagnostics and
Troubleshooting section of this manual.
Select a mounting surface for the SmartMotor that allows installation using the mounting
holes provided. The area selected should allow for free air circulation around the control.
Provide at least two inches of clearance on all sides for maximum cooling efficiency.
Caution:
Do not mount the SmartMotor with the control cover in the down
position. The cover must face up or to one side to keep liquids and
contaminants away from the heatsink.
Caution:
Avoid locating the SmartMotor immediately above or beside heat
generating equipment, or directly below water or steam pipes.
Vibration Considerations
Excessive vibration can cause failure of the control. If control is subjected to vibration
levels greater than 1G at 10 to 60 Hz, the control must be shock mounted.
Altitude Derating
Ratings apply to 3300 feet (1000 meters) altitude with no derating required. For
installations at higher altitudes derate the continuous and peak output currents of the
control by 2% for each 1000 feet above 3300 feet.
Temperature Derating
Control ratings apply to 40°C. Derate output by 2% per °C above 40°C. Maximum
ambient is 55°C.
Wiring Consideration
All logic and control connections are made at the 15 pin J1 connector shown in Figure
3-1. All external wires for the SmartMotor should be run in a conduit that is separate from
all other wiring. Be sure to use Class 1 wiring. The use of shielded wire is recommended
for all control wiring.
MN750
Receiving & Installation 3-1
AC Power Considerations Interconnection wiring is required between components such as the AC power source,
SmartMotor, optional operator control stations, etc. Wire connectors that are used must
be the correct size and installed using the crimp tool specified by the connector
manufacturer.
Caution:
AC Line Impedance
Do not use power factor correction capacitors on the input power
lines to the SmartMotor. Damage to the control may result if they
are used.
The Baldor SmartMotor requires a minimum line impedance of 1% (voltage drop at the
input is 1% minimum at rated input current). If the incoming power line does not have a
minimum of 1% impedance, a line reactor can be used to provide the needed impedance
in most cases. Use the following formula to calculate the size of the line reactor you must
provide. Line reactors are available from Baldor.
Note: Continuous input current requirement is provided in Table 3-1.

Line reactors serve several purposes which include:
3-2 Receiving & Installation
1.
Minimize voltage spikes from the power line that may otherwise cause the
control to trip on over voltage spikes.
2.
Minimize voltage harmonics from the control to the power line.
3.
Provide additional short circuit capability at the control.

Note: All wire sizes are based on 75° C copper wire. Smaller gauge wire that has a
greater temperature rating may be used per NEC and local codes.
Recommended breakers/fuses are based on 25° C ambient, MAX continuous
output current and no harmonic current.
Be sure a suitable input power protection device is installed. Use the recommended
circuit breaker or fuses listed in Table 3-1. Input and output wire size is based on the use
of copper conductor wire rated at 75 °C. The table is specified for SmartMotors that use a
NEMA B motor design.

1.
Be sure drive operation is terminated and secured.
2.
Remove all power sources from the motor.
3.
Remove cover. Remove the four (4) screws that secure the control cover and
remove cover.
4.
Connect the incoming AC power wires from the protection devices to L1, L2
and L3 at the Main Circuit Terminals (torque to 11 lb-in). The phase rotation is
not important as the control is not phase sensitive.
5.
Connect earth ground to the “Power Ground”. Be sure to comply with local
codes (torque to 50 lb-in).
6.
Install the control cover. Place the cover on the control and install & tighten the
four (4) screws that secure the control cover.
Operation of the SmartMotor using a DC power source is possible. The DC power leads
should be connected to L1 and L2 using disconnect and protection devices. The DC
voltage level must be equivalent to the full wave rectified value of the nominal rated AC
input voltage. For example, 280 to 340 VDC (for a 230 VAC rating) and 535 to 680 VDC
(for a 460 VAC rating). Protective devices should be sized using the equivalent AC
ratings.

Pre-Operation Checklist
Check of Electrical Items
CAUTION: After completing the installation but before you apply power, be
sure to check the following items.
1.
Verify AC line voltage at source matches the SmartMotor rating.
2.
Inspect all power connections for accuracy, workmanship, tightness and
compliance to codes.
3.
Verify SmartMotor is grounded to earth ground.
4.
Check all signal wiring for accuracy.
5.
Be certain all brake coils, contactors and relay coils have noise suppression.
This should be an R-C filter for AC coils and reverse polarity diodes for DC
coils. MOV type transient suppression is not adequate.
Check of Motor and Coupling
1.
Verify freedom of motion of the motor shaft.
2.
Verify that motor couplings are tight without backlash.
3.
Verify the holding brakes, if any, are properly adjusted to fully release and set to
the desired torque value.
Temporary Application of Power
MN750
1.
Check all electrical and mechanical connections before applying power to the
SmartMotor.
2.
Verify that control logic inputs at the J1 connector are proper.
3.
Temporarily apply power and observe that the bus power indicator is on or that
the optional keypad display is on (if Keypad is connected). If this indication
does not occur, check all connections and verify input voltage. If fault indication
occurs, refer to the troubleshooting section of this manual.
4.
Disconnect all power from the SmartMotor.

Set the desired maximum output frequency by setting the Max Output Freq
parameter in the Level 2 Output Limits block.
10. If the desired peak current limit is different than presently set the PK Current
Limit parameter in the Level 2 Output Limits block.
11. If using an external analog command, check ANA CMD Select parameter to
verify the SmartMotor is ready to accept your analog command signal.
12. Set the desired Volts/Hertz ratio by setting the V/HZ Profile Parameter in the
Level 2 V/HZ and Boost Block.
13. If the load is a high initial starting torque type, the Torque Boost parameter in
the Level 1 V/HZ and Boost Block may need to be increased. Also, the ACCEL
TIME #1 parameter in the Level 1 ACCEL/DECEL Rate block may need to be
increased.

Troubleshooting
Overview
The Baldor SmartMotor requires very little maintenance, if any, and should provide
years of trouble free operation when installed and applied correctly. Occasional visual
inspection should be considered to insure tight wiring connections and to avoid
accumulation of any dust, dirt, or foreign debris. The SmartMotor should be physically
located in such a manner as to protect the internal circuits and associated external wiring
from any accumulation of moisture or other types of liquid contaminants.
Troubleshooting
Before attempting to service this equipment, all input power should be removed from the
SmartMotor to avoid the possibility of electrical shock. The servicing of this equipment
should be handled by a qualified electrical service technician experienced in high power
electronics.
Most troubleshooting can be performed using only a digital voltmeter having an input
impedance exceeding 1 megohm. In some cases, an oscilloscope with 5 MHZ minimum
bandwidth may be useful. Before consulting the factory, check that all power and control
wiring is correct and installed per the recommendations given in this manual.
