OverviewIf 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. This 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 control. Refer to Section 3 “Physical Location” procedure.
3.Connect AC power, refer to Section 3 “Three Phase Motor and Control
Connections”.
4.Connect the motor, refer to Section 3 “Three Phase Motor and Control
Connections”.
5.Connect the resolver, refer to Section 3 “Resolver Feedback”.
6.Install dynamic brake hardware, if required. Refer to Section 3 “Optional
Dynamic Brake Hardware”.
7.Connect the keypad to the keypad connector of the main control board. Refer
to Section 3 “Keypad Installation Procedure”.
Quick Start ChecklistCheck 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 control rating.
2.Inspect all power connections for accuracy, workmanship and torque as well as
compliance to codes.
3.Verify control and motor are grounded to each other and the control is
connected 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 Motors and Couplings
1.Verify freedom of motion of the motor shaft.
2.Verify that all 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.

Section 2
General Information
OverviewThe Baldor Series 23H PWM control uses a closed loop control scheme using an
algorithm to adjust the phase of voltage and current applied to a three phase permanent
magnet synchronous motor. The servo control adjusts the motor current to produce
maximum torque from base speed down to and including zero speed. The frequency of
the voltage applied to the motor follows the electrical cycles per revolution based on the
mechanical speed of the rotor. This provides instantaneous adjustment of the voltage
and current phasing in response to speed and position feedback from a resolver mounted
to the motors’ shaft.

Receiving & Installation
Receiving & InspectionWhen you receive your control, 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 temperature and
humidity specifications. (Refer to Section 7 of this manual).
Physical LocationThe mounting location of the control is important. It should be installed in an area that is
protected from direct sunlight, corrosives, harmful gases or liquids, dust, metallic
particles, shock and vibration.
Several other factors should be carefully evaluated when selecting a location for
installation:
1.For effective cooling and maintenance, the control should be mounted vertically
on a flat, smooth, non-flammable vertical surface. Table 3-1 lists the Watts
Loss ratings for enclosure sizing.
2.At least two inches clearance must be provided on all sides for air flow.
3.Front access must be provided to allow the control cover to be opened or
removed for service and to allow viewing of the Keypad Display.
Controls packaged in a floor mounted enclosure must be positioned with
clearance to open the enclosure door. This clearance will also provide
sufficient air space for cooling.
4.Altitude derating. Up to 3300 feet (1000 meters) no derating required. Above
3300 ft, derate the continuous and peak output current by 2% for each 1000 ft.
5.Temperature derating. Up to 40°C no derating required. Above 40°C, derate
the continuous and peak output current by 2% per °C. Maximum ambient is
55°C.

Receiving & Installation 3-3MN723
Electrical InstallationInterconnection wiring is required between the motor control, AC power source, motor,
host control and any operator interface stations. Use listed closed loop connectors that
are of appropriate size for wire gauge being used. Connectors are to be installed using
crimp tool specified by the manufacturer of the connector. Only Class 1 wiring should be
used.
Baldor Series H controls feature UL approved adjustable motor overload protection
suitable for motors rated at no less than 50% of the output rating of the control. Other
governing agencies such as NEC may require separate over–current protection. The
installer of this equipment is responsible for complying with the National Electric Code
and any applicable local codes which govern such practices as wiring protection,
grounding, disconnects and other current protection.
System GroundingBaldor Controls are designed to be powered from standard three phase lines that are
electrically symmetrical with respect to ground. System grounding is an important step in
the overall installation to prevent problems. The recommended grounding method is
shown in Figure 3-1.

System Grounding Continued
Ungrounded Distribution System
With an ungrounded power distribution system it is possible to have a continuous current
path to ground through the MOV devices. To avoid equipment damage, an isolation
transformer with a grounded secondary is recommended. This provides three phase AC
power that is symmetrical with respect to ground.
Input Power Conditioning
Baldor controls are designed for direct connection to standard three phase lines that are
electrically symmetrical with respect to ground. Certain power line conditions must be
avoided. An AC line reactor or an isolation transformer may be required for some power
conditions.
If the feeder or branch circuit that provides power to the control has
permanently connected power factor correction capacitors, an input AC line
reactor or an isolation transformer must be connected between the power factor
correction capacitors and the control.
If the feeder or branch circuit that provides power to the control has power
factor correction capacitors that are switched on line and off line, the capacitors
must not be switched while the control is connected to the AC power line. If the
capacitors are switched on line while the control is still connected to the AC
power line, additional protection is required. TVSS (Transient Voltage Surge
Suppressor) of the proper rating must be installed between the AC line reactor
or an isolation transformer and the AC input to the control.
Line ImpedanceThe Baldor control requires a minimum line impedance. If the impedance of the incoming
power does not meet the requirement for the control, a 3 phase line reactor can be used
to provide the needed impedance in most cases. Line reactors are optional and are
available from Baldor.
Control SizeA, B, C, D, EB2, C2, D2, F, G
Line Impedance Required3%1%
The input impedance of the power lines can be determined as follows:
Measure the line to line voltage at no load and at full rated load.
Use these measured values to calculate impedance as follows:

Line ReactorsThree phase line reactors are available from Baldor. The line reactor to order is based on
the full load current of the motor (FLA). If providing your own line reactor, use the
following formula to calculate the minimum inductance required.

Load ReactorsLine reactors may be used at the control output to the motor. When used this way, they
are called Load Reactors. Load reactors serve several functions that include:
Protect the control from a short circuit at the motor.
Limit the rate of rise of motor surge currents.
Slowing the rate of change of power the control delivers to the motor.
Load reactors should be installed as close to the control as possible. Selection should be
based on the motor nameplate FLA value.

AC Main Circuit Considerations
Protection DevicesBe sure a suitable input power protection device is installed. Use the recommended
circuit breaker or fuses listed in Tables 3-2 through 3-3 (Wire Size and Protection
Devices). Input and output wire size is based on the use of copper conductor wire rated
at 75 °C. The table is specified for NEMA B motors.
Circuit Breaker:1 phase, thermal magnetic.
Equal to GE type THQ or TEB for 230 VAC
3 phase, thermal magnetic.

Time Delay Fuses:230 VAC, Buss FRN
460 VAC, Buss FRS to 600A (KLU 601 - 1200A)
Power DisconnectA power disconnect should be installed between the input power service and the control
for a fail safe method to disconnect power. The control will remain in a powered-up
condition until all input power is removed from the control and the internal bus voltage is
depleted.
Note: All wire sizes are based on 75°C copper wire. Higher temperature smaller gauge wire may be used per NEC
and local codes. Recommended fuses/breakers are based on 40°C ambient, maximum continuous control
output current and no harmonic current.
Receiving & Installation 3-7MN723
AC Line Connections
Reduced Input Voltage Derating All power ratings stated in Section 7 are for the stated nominal AC input
voltages (230 or 460VAC). The power rating of the control must be reduced when
operating at a reduced input voltage. The amount of reduction is the ratio of the voltage
change.
Examples:
A 10HP, 230VAC control operating at 208VAC has a reduced power rating of 9.04HP.
10HP
Likewise, a 10HP, 460VAC control operating at 380VAC has a reduced power rating of
8.26HP.
10HP
To obtain the full output rating of 10HP in either case requires a 15HP Control.
380-400 VAC Operation Size A, B, B2, C2 and D2 460VAC controls may be used directly with a 380-400 VAC
power source, control modification is not necessary.
Size C, D, E, F and G 460VAC controls all require modification for operation on the
reduced line voltage. Specifically, the control transformer must have the wire on terminal
5 (for 460V) moved to terminal 4 (for 380-400V).

Single Phase Input Power ConsiderationsSingle phase operation of G and H size controls is not possible.
Single phase AC input power can be used to power the control instead of three phase for
control sizes A, B, B2, C, C2, D, D2, E and F. The specifications and control sizes are
listed in Section 7 of this manual. If single phase power is to be used, the rated
Horsepower of the control may have to be reduced (derated). In addition, power wiring
and jumper changes are required.
Single phase rating wire size and protection devices are listed in Tables 3-4 and 3-5.
Single Phase Control Derating: Single phase power derating requires that the continuous and peak current ratings
of the control be reduced by the following percentages:
1.3–10A 230 and 2–5A 460 VAC controls:
No derating required.
2.15–28A (Size B and B2) 230 and 5–15A 460 VAC controls:
Derate HP by 40% of the nameplate rating.
3.42–55A (Size C) and Larger 230 and 460 VAC controls:
Derate HP by 50% of the nameplate rating.

The RUA Dynamic Brake assembly is designed for controls that have built in dynamic
brake hardware. Be sure to disconnect the internal resistor wires from control terminals.
These factory installed wires must be removed and the wire ends insulated with electrical
tape to prevent contact with other components. The braking capability may also need to
be disabled in software. For Baldor controls, reduce the resistor ohms to the lowest value
and increase the resistor watts to greatest value. Be sure to select the proper size kit
based on the dissipation rating of the resistor(s) to handle the average watts of the
overhauling or cyclic load.
