Precautions

Do not touch any circuit board, power device or electrical connection before you first
ensure that no high voltage is present at this equipment or other equipment to which it is
connected. Electrical shock can cause serious or fatal injury. Only qualified personnel
should attempt to start-up, program or troubleshoot this equipment.

The motor circuit might have high voltages present whenever AC power is applied, even
when the motor is not moving. Electrical shock can cause serious or fatal injury.

After AC power has been removed from the MotiFlex e100, high voltages (greater than

50 VDC) can remain on power connections for up to 5 minutes, while the DC bus circuitry
discharges. Do not touch the DC bus, regeneration resistor, or other power connections
during this period.

If a motor is driven mechanically, it might generate hazardous voltages that are conducted
to its power terminals. The enclosure must be earthed/grounded to prevent possible shock
hazard.

Be sure the system is properly earthed/grounded before applying power. Do not apply AC
power before you ensure that earths/grounds are connected. Electrical shock can cause
serious or fatal injury.

General Information 1-3MN1943

MEDICAL DEVICE / PACEMAKER DANGER: Magnetic and electromagnetic fields in the
vicinity of current carrying conductors and industrial motors can result in a serious health
hazard to persons with cardiac pacemakers, internal cardiac defibrillators, neurostimulators,
metal implants, cochlear implants, hearing aids, and other medical devices. To avoid risk,
stay away from the area surrounding a motor and its current carrying conductors.

Be sure all wiring complies with the National Electrical Code and all regional and local
codes. Improper wiring may result in unsafe conditions.

The stop input to this equipment should not be used as the single means of achieving a
safety critical stop. Drive disable, motor disconnect, motor brake and other means should
be used as appropriate.

Improper operation or programming of the drive may cause violent motion of the motor and
driven equipment. Be certain that unexpected motor 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.

If the drive enable signal is already present when power is applied to the MotiFlex e100, the

motor could begin to move immediately.

The metal heatsink on the left side of the MotiFlex e100 can become very hot during

normal operation.

The metal part of the MotiFlex e100 case incorporates prominent edges and corners that

may cause minor injury if the drive is handled without proper care and attention.

Take care when lifting. The 48 A and 65 A models weigh 12.45 kg (27.4 lb). Seek
assistance if necessary. When carrying, do not suspend the unit from the removable front
panels as they could detach and cause the unit to be dropped.

When operating a rotary motor with no load coupled to its shaft, remove the shaft key to
prevent it flying out when the shaft rotates.

A regeneration resistor may generate enough heat to ignite combustible materials.
To avoid fire hazard, keep all combustible materials and flammable vapors away from the
brake resistors.

To prevent equipment damage, be certain that the input power has correctly sized protective
devices installed.

To prevent equipment damage, be certain that input and output signals are powered and
referenced correctly.

To ensure reliable performance of this equipment be certain that all signals to/from the drive
are shielded correctly.

Suitable for use on a circuit capable of delivering not more than the RMS symmetrical short
circuit amperes listed here, at the rated maximum voltage (480 VAC):

1-4 General Information MN1943

Avoid locating the drive immediately above or beside heat generating equipment, or directly
below water or steam pipes.

Avoid locating the drive in the vicinity of corrosive substances or vapors, metal particles and
dust.

Do not connect AC power to the drive terminals U, V and W. Connecting AC power to these
terminals may result in damage to the drive.

Baldor does not recommend using “Grounded Leg Delta” transformer power leads that may
create earth/ground loops and degrade system performance. Instead, we recommend using
a four wire Wye.

Drives are intended to be connected to a permanent main power source, not a portable
power source. Suitable fusing and circuit protection devices are required.

The safe integration of the drive 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 these are 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.

Drives 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 drive should have specifications compatible to the
drive. If not installed in an electrical cabinet, barriers around the equipment are required.

Failure to meet cooling air flow requirements will result in reduced product lifetime and/or
drive overtemperature trips.

Violent jamming (stopping) of the motor during operation may damage the motor and drive.

Operating the MotiFlex e100 in Torque mode with no load attached to the motor can cause

the motor to accelerate rapidly to excessive speed.

Do not tin (solder) exposed wires. Solder contracts over time and may cause loose
connections. Use crimp connections where possible.

Electrical components can be damaged by static electricity. Use ESD (electrostatic
discharge) procedures when handling this drive.

If the drive is subjected to high potential (‘hipot’) testing, only DC voltages may be applied.
AC voltage hipot tests could damage the drive. For further information please contact your
local Baldor representative.

Ensure that encoder wires are properly connected. Incorrect installation may result in
improper movement.

Removing the cover will invalidate UL certification.

3.2 Mech an ical installation

It is essential that you read and understand this section before beginning the
installation

.

Take care when lifting. The 48 A and 65 A models weigh 12.45 kg (27.4 lb). Seek
assistance if necessary. When carrying, do not suspend the unit from the
removable front panels as they could detach and cause the unit to be dropped.

Avoid locating the MotiFlex e100 immediately above or beside heat generating

equipment, or directly below water steam pipes.

Avoid locating the MotiFlex e100 in the vicinity of corrosive substances or vapors,

metal particles and dust.

Failure to meet cooling air flow requirements will result in reduced product lifetime
and/or drive overtemperature trips.

The safe operation of this equipment depends upon its use in the appropriate environment.
The following points must be considered:

H The MotiFlex e100 must be installed indoors, permanently fixed and located so that it can

only be accessed by service personnel using tools. When installed in a cabinet, the cabinet
must have a volume of at least 0.19 m

3

(6.84 cu.ft). If not installed in a cabinet, barriers

around the equipment are required.

H The maximum suggested operating altitude is 1000 m (3300 ft).

H The MotiFlex e100 must be installed where the pollution degree according to EN61800-5-1

shall not exceed 2.

H The optional 24 VDC control circuit backup supply must be installed so that the 24 VDC

supplied to the unit is isolated from the AC supply either by using double or reinforced
insulation, or by using basic insulation with a protective earth.

H The input of the control circuit must be limited to Extra Low Voltage circuits.

H Both the AC supply and the optional 24 VDC control circuit backup supply must be fused.

H The atmosphere must not contain flammable gases or vapors.

H There must not be abnormal levels of nuclear radiation or X-rays.

H To comply with CE directive 2004/108/EC an appropriate AC filter must be installed.

H The MotiFlex e100 must be secured by the slots in the metal mounting flanges. The

protective earth/ground (the threaded studs on the top and bottom mounting flanges) must
be bonded to a safety earth/ground using either a 25 A conductor or a conductor of three
times the peak current rating - whichever is the greater.

H The metal tab at the bottom of the case is used for attaching a cable clamp (section A.1.6).

H The D-type connectors on the top and bottom panels of the MotiFlex e100 are secured using

two hexagonal jack screws (sometimes known as “screwlocks”). If a jack screw is removed
accidentally or lost it must be replaced with a #4-40 UNC jack screw with an external male
threaded section no longer than 10 mm (0.4 in).

H The 48 A and 65 A MotiFlex e100 have a recess at the rear of the product which is filled

with a block of packaging foam. Remove this foam before mounting the drive.

3.2.4 Mounting the MotiFlex e100

Ensure you have read and understood the Mechanical installation and location requirements in
section 3.2. Mount the MotiFlex e100 vertically on its rear side, the side opposite the front panel.
M5 bolts or screws should be used to mount the MotiFlex e100. Detailed dimensions are shown

in section 3.2.1.

Note: The 48 A and 65 A MotiFlex e100 have a recess at the rear of the product which is

filled with a block of packaging foam. Remove this foam before mounting the drive.

For effective cooling, the MotiFlex e100 must be mounted upright on a smooth vertical metal
surface. The MotiFlex e100 is designed to operate in an ambient temperature of 0 °C to 45 °C

(32 °F to 1 13 °F). Output current must be derated between 45 °C (1 13 °F) and the absolute
maximum ambient temperature of 55 °C (131 °F). All models incorporate cooling fans and are
designed to operate without any additional cooling methods.

Temperature derating characteristics are shown in sections 8.3.5 to 8.3.14.

3.2.4.1 Mounting multiple drives for DC bus sharing

The MotiFlex e100 is designed to be mounted in close contact with other MotiFlex e100s, to allow

the optional DC busbar kits (Baldor parts OPT-MF-DC-A, -B, -C or -D) to be connected across
the top of the drives. Each busbar kit contains two busbars and the necessary screws. When
mounting drives for DC bus sharing it is essential that they are accurately positioned in contact
with the neighboring drive, otherwise the busbars will not fit.

Mount the rightmost drive first, but do not fully tighten the top left screw. Take the next drive and
hold it against the left side of the first drive. Slide it downwards until the alignment tab (see Figure

4) on the side of the mounting flange fits behind the matching cutout on the first drive’s mounting
flange. Tighten the first drive’s top left screw. Holding the second drive in place, mark its mounting
holes. Remove the second drive, finish the mounting holes and then remount the drive. Use the
same procedure to mount further drives to the left of the second drive.

Alignment tab

1. Mount rightmost
drive first, leaving
top left screw
slightly loose.

2. Press second drive
against the first drive...

3. ...and slide down until alignment

tab engages behind fi rst drive.

3.2.4.2 Attaching the busbars for DC bus sharing

Busbars are supplied in kits, comprising a pair of busbars and all screws and washers required
for fitting. There are 4 different busbar sizes, allowing any combination of narrow bodied

MotiFlex e100 (1.5 A ~ 16 A models), wide bodied MotiFlex e100 (21 A ~ 33.5 A models) or
extended bodied MotiFlex e100 (48 A ~ 65 A models) to be connected, as shown in Figure 6. Size

3 and size 4 busbars have an insulating sleeve, since parts of them are exposed when fitted. See
also section 3.5 for details about sharing the DC bus.

Hazardous voltages exist underneath the drive’s hinged top cover! Before
lifting the cover ensure that AC power has been removed from the source
drive and at least 5 minutes have elapsed to allow the DC bus output
capacitors to discharge. Use only original Baldor busbar kits, parts

OPT-MF-DC-x.

Always observe the correct polarity. The busbar nearest the front of the

MotiFlex e100 is positive. The busbar at the rear is negative, as shown in Figure 5.

1. Loosen the busbar c over retaining screw to reveal the busbar
mounting pads.

2. Attach the busbars using the supplied screws and washers.
Tighten screws to approximately 2 N·m (17.7 lb-in).

3. Close the busbar cover and tighten the retaining screw to
approximately 1 N·m (8.9 lb-in). Do not exceed 2 N·m (17.7 lb-in).

Ta ble 1 - Maximum internal trip temperatures

The MotiFlex e100 can detect problems with its cooling fan, such as disconnection (fan loss) or

overcurrent caused by stalling. The 10.5 A and 16 A models incorporate two cooling fans; one
fan operates continuously, but to increase overall lifetime and efficiency the second fan operates
only when necessary. Also, if a fault is detected on the first fan, the other one will turn on. The
48 A and 65 A models incorporate four cooling fans; none of the fans are required in normal
conditions, but all four will operate when necessary.

3.2.5.1 Effects of mounting surface and proximity

If the MotiFlex e100 is mounted above or below another MotiFlex e100 (or other obstruction),

there should be a minimum space of 90 mm to maintain effective cooling. Remember that when

a MotiFlex e100 is mounted above another MotiFlex e100 or heat source, it will be receiving air

that has been already heated by the device(s) below it.

3.4 AC power connections

This section provides instructions for connecting the AC power supply. For full specifications,
see section 8.

The installer of this equipment is responsible for complying with NEC (National Electric Code)
guidelines or CE (Conformite Europeene) directives and application codes that govern wiring
protection, earthing/grounding, disconnects and other current protection.

Electrical shock can cause serious or fatal injury. Do not touch any 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.

To prevent equipment damage, be certain that the input power has correctly rated
protective devices installed.

To prevent equipment damage, be certain that input and output signals are powered
and referenced correctly.

To ensure reliable performance of this equipment be certain that all signals to/from

the MotiFlex e100 are shielded correctly.

MotiFlex e100 drives are designed to be powered from standard three-phase lines that are

electrically symmetrical with respect to earth/ground. The power supply module within all

MotiFlex e100 models provides rectification, smoothing and current surge protection. Fuses or

circuit breakers are required in the input lines for cable protection.

Note: A Residual Current Device (RCD) must not be used for fusing the drive.

An appropriate type of circuit breaker or fuse must be used.

All interconnection wires should be in metal conduits between the MotiFlex e100, AC power

source, motor, host controller and any operator interface stations.

3.4.1 Earthing / grounding

Permanent earth/ground bonding points are provided on the mounting flanges, which must be
used as the protective earth. They are labeled with the protective earth symbol and do not form
any other mechanical function. Earthing methods are shown in section 3.4.4.

These protective earth/ground points prevent exposed metal parts of the MicroFlex e100 from

becoming live in the event of a wiring error or other failure. Connecting these points to earth does
not provide protection against electromagnetic contamination received or emitted by the drive
and its associated wiring. For example, the motor power output cable supplies a high frequency
high current waveform to the motor, so the cable’s shielding must be separately bonded to a
functional earth point to prevent the cable radiating electromagnetic contamination into the
surrounding area. Such contamination can cause spurious errors in apparently unrelated parts
of the installation, such as low voltage communication cables. See sections 3.4.2 and 3.7.1 for
detailed installation instructions that will help reduce electromagnetic contamination.

Note: When using unearthed/ungrounded distribution systems, an isolation transformer

with an earthed/grounded secondary is recommended. This provides three-phase
AC power that is symmetrical with respect to earth/ground and can prevent
equipment damage.
