1-2 Quick Start Guide MN715
Section 2
General Information
Overview The Baldor Series 15H control is a PWM inverter motor control. The control converts AC
line power to fixed DC power. The DC power is then pulse width modulated into
synthesized three-phase AC line voltage for the motor. In this way, the control converts
the fixed input frequency to variable output frequency to cause the motor to have variable
speed operation.
The rated horsepower of the control is based on a NEMA design B four pole motor and
60Hz operation at nominal rated input voltage. If any other type of motor is used, or input
voltage other than 230, 460 or 575 VAC is applied to the input terminals, the control
should be sized to the motor using the rated current of the motor.
The Baldor Series 15H control may be used in many different applications. It may be
programmed by the user to operate in four different operating zones; standard constant
torque, standard variable torque, quiet constant torque or quiet variable torque. It can
also be configured to function in a number of operating modes for custom operation.
It is the responsibility of the user to determine the optimum operating zone and operating
mode for the application. These choices are programmed using the keypad as explained
in the programming section of this manual.
CE Compliance A custom unit may be required, contact Baldor. Compliance to Directive 89/336/EEC is
the responsibility of the system integrator. A control, motor and all system components
must have proper shielding grounding and filtering as described in MN1383. Please refer
to MN1383 for installation techniques for CE compliance.

General Information
Electrical Installation To make electrical connections, use UL 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 Grounding Baldor 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.

General Information
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 Impedance The 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 Size A, B, C, D, E B2, C2, D2, F, G, G2, G+, H
Line Impedance Required 3% 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:

Use 314 if input power is 50Hz.
Load Reactors Line 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
Power Disconnect A 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.
Protective Devices Recommended fuse sizes are based on the following:
115% of maximum continuous current for time delay.
150% of maximum continuous current for Fast or Very Fast action.
Note: These general size recommendations do not consider harmonic currents or
ambient temperatures greater than 40°C.
Be sure a suitable input power protection device is installed. Use the recommended
circuit breaker or fuses listed in tables 3-2 through 3-4 (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.

AC Line Connections
Reduced Input Voltage Derating All power ratings stated in Section 6 are for the stated nominal AC input
voltages (230, 460 or 575VAC). 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
208VAC
230VAC
+ 9.04hp
Likewise, a 10hp, 460VAC control operating at 380VAC has a reduced power rating of
8.26hp.
10HP
380VAC
460VAC
+ 8.26hp
To obtain the full output rating of 10hp in either case requires a 15hp Control.
380-400VAC Operation Be sure all power to the control is disconnected before proceeding.
Size A, B, B2, C2 and D2 controls may be used directly with a 380-400VAC power
source, control modification is not necessary.
Size C, D, E, F and G controls all require modification for operation on the reduced line
voltage.
Tap change procedure (size C, D, E and F controls)
1. Be sure drive operation is terminated and secured.
2. Remove all power sources from the control. If power has been applied, wait at
least 5 minutes for bus capacitors to discharge.
3. Remove or open the front cover and locate the control transformer (Figure 3-3).
4. Remove the wire from terminal 5.
5. Place the wire that was removed from terminal 5 onto terminal 4.
6. Install or close the front cover.

General Information
Single Phase Input Power Considerations Single 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 6 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 3 wire connections are standard in the
USA. However, single phase 2 wire connection is used in most of the world. Both
connections types are shown.
Single phase rating wire size and protection devices are listed in Tables 3-6 and 3-7.
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. 1-2 hp 230 and 460VAC controls:
No derating required.
2. 3-25 hp (Size B, B2 and C2) 230 and 460VAC controls:
Derate hp by 40% of the nameplate rating.
3. 15 hp (Size C, D2) and Larger 230 and 460VAC controls:
Derate hp by 50% of the nameplate rating.

Motor Brake Connections For motors with spring set brakes, connect the brake power leads and the motor power
leads separately. Because the inverter has variable voltage output to the motor, the
inverter may not supply enough power at low frequencies for proper brake operation. If
using a motor with an internally connected brake, the brake power leads must be
connected to a separate power source for proper brake operation.
