2–2 General Information MN735

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.

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.

WARNING: Be sure all wiring complies with the National Electrical Code and

all regional and local codes or CE Compliance. Improper wiring
may cause a hazardous condition.

WARNING: Be sure the system is properly grounded before applying power.

Do not apply AC power before you ensure that grounds are
connected. 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. Electrical shock
can cause serious or fatal injury.

WARNING: Improper operation may cause violent motion of the motor and

driven equipment. Be certain that unexpected movement will not
cause injury to personnel or damage to equipment.

WARNING: Motor circuit may have high voltage present whenever AC power

is applied, even when motor is not moving. Electrical shock can
cause serious or fatal injury.

WARNING: If a motor is driven mechanically, it may generate hazardous

voltages that are conducted to its power input terminals. The
enclosure must be grounded to prevent a possible shock hazard.

WARNING: The user must provide an external hard-wired emergency stop

circuit to disable the control in the event of an emergency.

Continued on next page.

General Information 2–3MN735

Caution: To prevent equipment damage, be certain that the input power

has correctly sized protective devices installed as well as a power
disconnect.

Caution: Avoid locating the control immediately above or beside heat

generating equipment, or directly below water or steam pipes.

Caution: Avoid locating the control in the vicinity of corrosive substances

or vapors, metal particles and dust.

Caution: Suitable for use on a circuit capable of delivering not more than

the RMS symmetrical short circuit amperes listed here at rated
voltage.

201–400 18,000
401–600 30,000
601–900 42,000

Caution: Baldor recommends not using “Grounded Leg Delta” transformer

power leads that may create ground loops and degrade system
performance. Instead, we recommend using a four wire Wye.

Caution: Logic signals are interruptible signals; these signals are removed

when power is removed from the drive.

Caution: The safe integration of the driver into a machine system is the

responsibility of the machine designer. Be sure to comply with
the local safety requirements at the place where the machine is to
be used. In Europe this is the Machinery Directive, the
ElectroMagnetic Compatibility Directive and the Low Voltage
Directive. In the United States this is the National Electrical code
and local codes.

Caution: Controls must be installed inside an electrical cabinet that

provides environmental control and protection. Installation
information for the drive is provided in this manual. Motors and
controlling devices that connect to the driver should have
specifications compatible to the drive.

Caution: Do not tin (solder) exposed wires. Solder contracts over time and

may cause loose connections.

Caution: Electrical components can be damaged by static electricity. Use

ESD (electro-static discharge) procedures when handling this
control.

Section 3
Receiving & Installation

Receiving & Inspection

Baldor Controls are thoroughly tested at the factory and carefully packaged
for shipment. When 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. Remove the control from the shipping container and remove all
packing materials. The container and packing materials may be
retained for future shipment.

3. Verify that the part number of the control you received is the same as
the part number listed on your purchase order.

4. Inspect the control for external physical damage that may have been
sustained during shipment and report any damage immediately to the
commercial carrier that delivered your control.

5. 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 humidity
and temperature specifications stated in this manual.

Location and Mounting

The location of the control is important. Installation should be in an area
that is protected from direct sunlight, corrosives, harmful gases or liquids,
dust, metallic particles, and vibration. Exposure to these can reduce the
operating life and degrade performance of the control.

Several other factors should be carefully evaluated when selecting a
location for installation:

To maintain compliance with European Electrical Safety Standard
VDE0160(1994)/EN50178 (1998) the control must be mounted inside an
enclosure that requires a tool for opening. The enclosure should provide
15dB attenuation to radiated emissions between 30–100MHz.
Mount the drive vertically on a solid, flat, non–flammable, vertical surface.
It can be panel–mounted, or rail–mounted on a rail complying with
EN50022 (35mm DIN). For DIN mount, hang the unit on the top DIN rail
and push the unit onto the bottom DIN rail until it snaps in to position.
Secure with a screw in the lower hole. See mounting drawing in Section 6
of this manual.

System Grounding Baldor Controls are designed to be powered from standard

three phase power lines that are electrically symmetrical with respect to
ground. System grounding is an important step in the overall installation to
prevent problems.

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.

S 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.

S 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.

Receiving & Installation 3–3MN735

Line Impedance The Baldor control requires a 1% line impedance minimum . 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.

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 Reactors Three 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.

377 Constant used with 60Hz power.

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:

S Protect the control from a short circuit at the motor.
S Limit the rate of rise of motor surge currents.
S 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.

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 fuses and wire sizes shown in Table 3-2 is based on the use
of copper conductor wire rated at 75 °C. The table is specified for NEMA B
motors.

Reduced Input Voltage Derating All power ratings stated in Section 6 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.

3–4 Receiving & Installation MN735

Examples:

A 5hp, 230VAC control operating at 208VAC has a reduced power rating of

4.5hp.

5HP

Likewise, a 3hp, 460VAC control operating at 380VAC has a reduced
power rating of 2.47hp.

3HP

Electrical Installation All interconnection wires between the control, AC power source,

motor, host control and any operator interface stations should be in metal
conduits or shielded cable must be used. 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.

Rubber

Grommet

Holes are required in the enclosure assembly to allow connections to be
made. Use the correct size rubber grommet, conduit coupling or 360
degree coupling.

Clamp Terminals To install a wire into a clamp terminal, first strip wire insulation

to 0.20–0.24 in. (5–6mm). Insert a flat–blade screwdriver, maximum blade
size 0.138 in. (3.5mm) into the adjacent hole. Do not twist or rotate the
screwdriver as this action may damage the terminal. A very slight
downward pressure on the screwdriver should open the terminals and allow
the wire to be inserted. Insert the wire into the clamp opening (Figure 3-4).
Remove the screwdriver. The terminal provides the correct force for a
secure connection.

Thermistor Connections (connections are shown in Figure 3-5).

This input is provided for over–temperature detection for motors that have
an internal thermistor. There is no polarity to the thermistor connections.

This provides “Basic” insulation only to the SELV control circuits and
assumes the motor has “Basic” insulation to the windings/mains circuits.
The thermistor type supported is PTC ‘Type A’ as defined in IEC 34–11 Part

2. The resistance thresholds are:
Rising temperature trip resistance: 1650 to 4000 ohms
Falling temperature trip reset resistance 750 to 1650 ohms

If the motor does not have an internal thermistor, you should disable the
thermistor trip function by:

Parameter Definitions You can program the Inverter for specific applications. The

Inverter is supplied with pre–programmed applications that can be used as
starting points for application–specific programming. Programming is simply
selecting an application, changing some of the parameter values and finally
saving the changes. Each application configures the terminal wiring for a
differently. The Inverter retains the new settings during power–down. The
next time the inverter is powered up, the new settings will be used.

PI Terms PI is used to control the response of any closed loop system. It is

used specifically in system applications involving the control of drives to
provide zero steady state error between Setpoint and Feedback, together
with good transient performance.

P

Proportional Gain (

501)

This is used to adjust the basic response of the closed loop control system.
The PI error is multiplied by the Proportional Gain to produce an output.

Integral (

P

502)

The Integral term is used to reduce steady state error between the setpoint
and feedback values of the PI. If the integral is set to zero, then there will
always be a steady state error.

Overdamped

The gains should be set–up so that a critically damped response is
achieved for a step change in setpoint. An underdamped or oscillatory
system can be thought of as having too much gain, and an overdamped
system has too little.

To set up the P gain, set the I gain to zero. Apply a step change in setpoint
that is typical for the System, and observe the response. Increase the gain
and repeat the test until the system becomes oscillatory. At this point,
reduce the P gain until the oscillations disappear. This is the maximum
value of P gain achievable.

If a steady state error is present, i.e. the feedback never reaches the
setpoint value, the I gain needs to be increased. As before, increase the I
gain and apply the step change. Monitor the output. If the output becomes
oscillatory, reduce the P gain slightly. This should reduce the steady state
error. Increasing the I gain further may reduce the time to achieve zero
steady state error.

These values of P and I can now be adjusted to provide the exact response
required for this step change.

Troubleshooting

Trips The trip display message is briefly displayed repeatedly (flashing) on the

screen to warn of an imminent trip. Some trip conditions need time to take
effect. The warning can allow you time to resolve the situation. The
message will clear when you use the keypad, but after a short time will
reappear until the problem is resolved, or the drive trips.

When a trip occurs, the control’s power stage is immediately disabled
causing the motor and load to coast to a stop. The trip is latched until action
is taken to reset it. This ensures that trips due to transient conditions are
captured and the Inverter is disabled, even when the original cause of the
trip is no longer present. At this time, the activated alarm is displayed on
the keypad display.

Reset a Trip

All trips must be reset before the Inverter can be re–enabled. A trip can
only be reset once the trip condition is no longer active, i.e. a trip due to a
heatsink over–temperature will not reset until the temperature is below the
trip level. You can reset the trip as follows:

1. Press the

(STOP) key to reset the trip and clear the alarm from

the display.

2. Remove and then re–apply the RUN command and the drive will run

normally.

Success is indicated by either

Dynamic Brake

230VAC 1 & 3 Phase Controls All controls are supplied without braking resistors.

Size 1 and 2 – 230VAC 1 Phase

Size 1 and 2 230VAC controls have no external dynamic brake capability.
Size 3 – 230VAC 3 Phase

Size 3 230VAC controls have internal brake circuit and can accept external
brake resistor.

460VAC 3 Phase Controls

Size 2 and 3 – 460VAC

Size 2 and 3 460VAC controls have internal brake circuit and can accept
external brake resistor. The dynamic brake circuit is designed for short term
stopping or braking only. It is not rated for a continuously overhauling load.

All controls are supplied without braking resistors. The dynamic brake
switch terminals allow easy connection of an external resistor. These
resistors should be mounted on a heatsink (enclosure panel) and covered
to prevent severe buring.

Brake Calculations

Brake assemblies must be rated to absorb the peak brake power during
deceleration and the average power over the complete cycle.

“EMC Law” or “Machine directive”.

The final mode of operation is defined only after installation into the user’s
equipment. It is the responsibility of the user to verify compliance.

The product conforms with the following standards:

EMC – Conformity and CE – Marking

The information contained herein is for your guidance only and does not
guarantee that the installation will meet the requirements of the council
directive 89/336/EEC.

The purpose of the EEC directives is to state a minimum technical
requirement common to all the member states within the European Union.
In turn, these minimum technical requirements are intended to enhance the
levels of safety both directly and indirectly.

Council directive 89/336/EEC relating to Electro Magnetic Compliance
(EMC) indicates that it is the responsibility of the system integrator to
ensure that the entire system complies with all relative directives at the time
of installing into service.

Motors and controls are used as components of a system, per the EMC
directive. Hence all components, installation of the components,
interconnection between components, and shielding and grounding of the
system as a whole determines EMC compliance.

The CE mark does not inform the purchaser which directive the product
complies with. It rests upon the manufacturer or his authorized
representative to ensure the item in question complies fully with all the
relative directives in force at the time of installing into service, in the same
way as the system integrator previously mentioned. Remember, it is the
instructions of installation and use, coupled with the product, that comply
with the directive.

CE Guidelines B–1MN735

Using CE approved components will not guarantee a CE compliant system!

1. The components used in the drive, installation methods used,
materials selected for interconnection of components are important.

2. The installation methods, interconnection materials, shielding, filtering
and grounding of the system as a whole will determine CE
compliance.

3. The responsibility of CE mark compliance rests entirely with the party
who offers the end system for sale (such as an OEM or system
integrator).

Baldor products which meet EMC directive requirements are indicated by a
“CE” mark. A duly signed CE declaration of conformity is available from Baldor.

EMC Wiring Technique

1 CABINET

The drawing shows an electroplated zinc
coated enclosure, connected to ground.
This enclosure has the following advantages:

- All parts mounted on the back plane are

Capacitor

Y

connected to ground.

- All shield (screen) connections are
connected to ground.
Within the cabinet there should be a spatial
separation between power wiring (motor and
AC power cables) and control wiring.

2 SCREEN CONNECTIONS

All connections between components must
use shielded cables. The cable shields must
be connected to the enclosure. Use
conductive clamps to ensure good ground
connection. With this technique, a good
ground shield can be achieved.

3 EMC - FILTER

The EMI or main filter should be mounted next
to the power supply (here BPS). For the
connection to and from the main filter
screened cables should be used. The cable
screens should be connected to screen
clamps on both sides. (Exception: Analog
Command Signal).

4 Grounding (Earth)

For safety reasons (VDE0160), all BALDOR
components must be connected to ground
with a separate wire. The diameter of the wire
must be at minimum AWG#6 (10mm@).
Ground connections (dashed lines) must be
made from the central ground to the regen
resistor enclosure and from the central ground
to the Shared Power Supply.

5 Y-CAPACITOR

The connection of the regeneration resistor
can cause RFI (radio frequency interference)
to be very high. To minimize RFI, a
Y-capacitor is used. The capacitor should
only be connected between the dynamic
brake resistor housing and terminal pin R1
(lead from Lin).
Recommendation:
0,1µF / 250VAC Type: PME265
BALDOR-Ordering-No.: ASR27104

B–2 CE Guidelines MN735

EMC Installation Instructions

To ensure electromagnetic compatibility (EMC), the following installation
instructions should be completed. These steps help to reduce interference.
Consider the following:

• Grounding of all system elements to a central ground point

• Shielding of all cables and signal wires

• Filtering of power lines

A proper enclosure should have the following characteristics:
A) All metal conducting parts of the enclosure must be electrically

connected to the back plane. These connections should be made with
a grounding strap from each element to a central grounding point . 

B) Keep the power wiring (motor and power cable) and control wiring

separated. If these wires must cross, be sure they cross at 90
degrees to minimize noise due to induction.

C) The shield connections of the signal and power cables should be

connected to the screen rails or clamps. The screen rails or clamps
should be conductive clamps fastened to the cabinet. 

D) The cable to the regeneration resistor must be shielded. The shield

must be connected to ground at both ends.

E) The location of the AC mains filter has to be situated close to the drive

so the AC power wires are as short as possible.

F) Wires inside the enclosure should be placed as close as possible to

conducting metal, cabinet walls and plates. It is advised to terminate
unused wires to chassis ground. 

G) To reduce ground current, use at least a 10mm

2

(6 AWG) solid wire

for ground connections.

 Grounding in general describes all metal parts which can be connected to a

protective conductor, e.g. housing of cabinet, motor housing, etc. to a
central ground point. This central ground point is then connected to the
main plant (or building) ground.

 Or run as twisted pair at minimum.
