Basic Installation 3-1MN1902
3.1 Introduction
You should read all the sections in Basic Installation to ensure safe installation.
This section describes the mechanical and electrical installation of the FlexDrive
II
in the
following stages:
H Location considerations
H Mounting the FlexDrive
II
H Connecting the AC power supply
H Connecting the optional customer supplied 24VDC control supply
H Connecting the motor
H Installing a regeneration resistor (Dynamic Brake resistor)
H Connecting the feedback device
H Connecting the drive enable input.
These stages should be read and followed in sequence.
3.1.1 Power sources
An AC power source (IEC1010 over-voltage category III or less) in the installation area is
required. This will need to be single or three-phase depending upon the type of FlexDrive
II
.
An AC power filter is required to comply with the CE directive for which the FlexDrive
II
was
tested (see section 3.4.5).
If the FlexDrive
II
requires an external (customer supplied) 24VDC logic supply then this must
be a regulated power supply with a continuous current supply capability of 1.75A (4A power on
surge). A 24V filter may be required to comply with the CE directive for which the FlexDrive
II
was tested (see section 3.4.5).
3.1.2 Hardware requirements
The components you will need to complete the basic installation are:
H The motor that will be connected to the FlexDrive
II
H A motor power cable
H A resolver or encoder feedback cable (and Hall cable for linear motors)
H With some applications there may be a requirement for a regeneration resistor (Dynamic
Brake).
Note: Without the regeneration resistor, the drive may produce an overvoltage fault. All
FlexDrive
II
models have overvoltage sensing circuitry, but only 2.5A and 5A
models (catalog numbers FDHxxxxxB-xxxx and FPHxxxxxB-xxxx) have an
internal regeneration resistor. For 7.5A, 15A, 20A and 27.5A models a
regeneration resistor must be purchased separately if required. See Appendix A.

3-2 Basic Installation MN1902
H A serial cable.
Note: The serial connector on the FlexDrive
II
(connector X6) can be configured as either
RS232 or RS485 / RS422. Pin 9 is used to carry +8V for powering some Baldor
keypad peripherals. Ensure that pin 9 is not connected to earth/ground or to
equipment that could be damaged by the +8V supply. See sections 4.4.3 and
4.4.4. A suitable cable is available from Baldor, catalog number CBL001-501.
H A PC (with one free COM port) with the following specification:

Mouse A mouse or similar pointing device
Operating system Windows 95, Windows 98, Windows ME,
Windows NT, Windows XP or Windows 2000
3.1.3 RS485 / RS422 systems
If you will be using RS485 / RS422 and your PC does not have an RS485 / RS422 connector,
an RS232 to 4-wire RS485 / RS422 converter will be required. These commercially available
devices convert the signals from the RS232/RS485 port (connector X6) to the signals
necessary for RS485 / RS422 communications. Special care must be taken with the pin
assignment on all RS485 / RS422 devices, as this can differ between products. Connectors
might need to be rewired to provide the correct pin assignment. The FlexDrive
II
pin
assignment is shown in section 4.4.3.
Note: If this is the first time you are installing a FlexDriveIIthen it is strongly
recommended that you use RS232 to get started and try RS485 later. This will
avoid any potential problems involving the RS232-RS485 converter. Selection of
RS232 or RS485 is controlled using DIP switch 10 - see section 3.9.6.
3.1.4 Tools and miscellaneous hardware
H Your PC operating system user manual might be useful if you are not familiar with
Windows

Basic Installation 3-5MN1902
H For effective cooling and maintenance, the FlexDriveIIshould be mounted on a smooth,
non-flammable vertical surface. The power handling capability is affected by the
temperature of the left side of the unit.
H At least 50mm (2 in) top and bottom clearance of the FlexDriveIImust be provided for
airflow.
H If multiple FlexDrive
II
are being mounted side by side there must be 13mm (0.5 in)
between them. The FlexDrive
II
nearest the side of the cabinet / enclosure must be
separated from it by at least 13mm (0.5 in).
H To comply with CE directive 89/336/EEC an appropriate AC filter must be installed. The
external customer supplied 24VDC logic supply might also require a 24V filter. See section
3.4.7.
H The threaded holes in the top and bottom of the enclosure are for cable clamps. The holes
are threaded for M4 bolts no longer than 12mm (0.47 in) in length. Longer bolts may short
circuit the electrical components inside the FlexDrive
II
.
H Each D-type connector on the front panel of the FlexDrive
II
is secured using two
hexagonal jack screws (sometimes known as “screwlocks”). If a jack screw is removed
accidentally or lost it must be replaced with an identical jack screw with an external male
threaded section of 5mm (0.2 in). Jack screws with longer threads could damage or short
circuit internal components.
3.2.1 Mounting the FlexDrive
II
Ensure you have read and understood the Mechanical installation and location requirements in
section 3.2. Mount your FlexDrive
II
on its rear side, the side opposite to the front panel.
The FlexDrive
II
must be mounted upright to ensure adequate cooling (you can check this by
ensuring that the Hazardous Voltages warning information is clearly readable to you).
M5 bolts or screws should be used to mount the FlexDrive
II
.

3.4 Power connections
This section provides instructions for connecting the AC power supply. It is important that you
refer to the correct front panel for your FlexDrive
II
package.
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.
WARNING: 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.
The power supply module within all FlexDrive
II
models provides rectification, smoothing and
current surge protection. On 2.5A and 5A models a regeneration resistor (Dynamic Brake
resistor) is also built-in. The power stage is internally fused and therefore self protected, but
fuses or circuit breakers are required in the input lines for cable protection (depending on local
codes and regulations).
A power disconnect should be installed between the AC supply and the input of the FlexDrive
II
for a fail safe method to disconnect power. On models with the internally generated 24VDC
logic supply (catalog numbers FDHxxxxx-xxx0 and FPHxxxxx -xxx0), the FlexDrive
II
will
remain operational until the internal bus voltage is depleted. Position and I/O information will
then be lost. On models with an external customer supplied 24VDC logic supply (catalog
numbers FDHxxxxx -xxx3 and FPHxxxxx-xxx3), position and I/O information will be retained
while the 24V supply is present.
Note: A Residual Current Device (RCD) must not be used for fusing the drive. A circuit
breaker or fuse must be used.
All interconnection wires should be in metal conduits between the FlexDrive
II
, AC power
source, motor, host controller and any operator interface stations. Use UL listed closed loop
connectors that are of appropriate size for the wire gauge being used. Connectors are to be
installed using only the crimp tool specified by the manufacturer of the connector. Only class 1
wiring should be used.
Baldor drives are designed to be powered from standard single and three-phase lines
(depending on model) that are electrically symmetrical with respect to earth/ground. Due to
the importance of system earthing/grounding for increased reliability, earthing/grounding
methods are shown in sections 3.4.1 and 3.4.2.
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.

The threaded hole in the top of the enclosure is for protective earth/ground connections.
The threaded hole in the bottom of the enclosure may be used as an additional functional
earth/ground connection for signals on connector X3. It may also be used to attach strain relief
clamps. The holes are threaded for M4 bolts no longer than 12mm (0.47 in) in length. Longer
bolts may short circuit the electrical components inside the FlexDrive

3.4.3 Input power conditioning
Baldor drives are designed for direct connection to standard single and three-phase lines
(depending on model) that are electrically symmetrical with respect to earth/ground. Certain
power line conditions must be avoided; an AC line reactor, an isolation transformer or a step
up/step down transformer may be required for some power conditions:
H If the feeder or branch circuit that provides power to the FlexDrive
II
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
FlexDrive
II
.
H If the feeder or branch circuit that provides power to the FlexDrive
II
has power factor
correction capacitors that are switched on line and off line, the capacitors must not be
switched while the drive is connected to the AC power line. If the capacitors are switched
on line while the drive is still connected to the AC power line, additional protection is
required. A Transient Voltage Surge Suppressor (TVSS) of the proper rating must be
installed between the AC line reactor (or isolation transformer) and the AC input to the
FlexDrive
II
.
3.4.3.1 Input power-cycling
If AC power has been removed from the FlexDrive
II
, it should not be reapplied for at least one
minute. This delay allows the input surge protection circuit to perform correctly. Power-cycling
the drive more frequently could cause nuisance trips when power is reapplied and reduce the
lifetime of the FlexDrive
II
.
3.4.4 Power disconnect and protection devices
A power disconnect should be installed between the input power service and the FlexDrive
II
for a fail-safe method to disconnect power. The FlexDriveIIwill remain in a powered condition
until all input power is removed from the drive and the internal bus voltage has depleted.
The FlexDrive
II
must have a suitable input power protection device installed. Recommended
circuit breakers are thermal magnetic devices (1 or 3 phase as required) with characteristics
suitable for heavy inductive loads (D-type trip characteristic). Recommended time delay fuses
are Buss FRN on 230V AC or equivalent, following the UL 508C recommendation of a fuse
size of four times the continuous output current of the drive. Dual element, time delay fuses
should be used to avoid nuisance trips due to inrush current when power is first applied.

Note: Power to single phase models may be derived by connecting two phases of an
appropriate three-phase supply (L1 and L2 for example). When supplying
AC
power in this way, the voltage between the two phases must not exceed the
rated
input voltage of the FlexDrive
II
. A two pole breaker must be used to isolate both
lines. Fuses must be fitted in both lines. Circuit breaker or fuse are not supplied.

3.4.5 Power supply filters
To comply with EEC directive 89/336/EEC, an AC power filter of the appropriate type must be

3.4.7 External customer supplied 24V control supply
Depending on model (catalog numbers FDHxxxxx-xxx3 and FPHxxxxx -xxx3) a 24VDC
control supply must be provided to power the control electronics. This is useful for safety
reasons where AC power needs to be removed from the power stage but the control
electronics must remain powered to retain position and I/O information. It is recommended
that a separate fused 24V supply is provided for the FlexDrive
II
. If other devices are likely to
be powered from the same 24V supply then a filter (Baldor catalog number FI0014A00) should
be installed to isolate the FlexDrive
II
from the rest of the system.

motor movement.
The motor power cable must be shielded for CE compliance. The connector or gland used at
the motor must provide 360 degree shielding. The maximum recommended cable length is
30.5m (100ft).
Note: For CE compliance the motor earth/ground should be connected to the drive
earth/ground.
3-16 Basic Installation MN1902
3.5.1 Motor circuit contactors
If required by local codes or for safety reasons, an M-Contactor (motor circuit contactor) may
be installed to provide a physical disconnection of the motor windings from the FlexDrive
II
(see section 3.5). Opening the M-Contactor ensures that the FlexDriveIIcannot drive the
motor, which may be necessary during equipment maintenance or similar operations. Under
certain circumstances, it may also be necessary to fit a brake to a rotary motor. This is
important with hanging loads where disconnecting the motor windings could result in the load
falling. Contact your local supplier for details of appropriate brakes.
CAUTION: If an M-Contactor is installed, the FlexDriveIImust be disabled at least
20ms before the M-Contactor is opened. If the M-Contactor is opened
while the FlexDrive
II
is supplying voltage and current to the motor, the
FlexDrive
II
may be damaged. Incorrect installation or failure of the
M-Contactor or its wiring may result in damage to the FlexDrive
II
.
Ensure that shielding of the motor cable is continued on both sides of the contactor.
