BULLETIN 1305 PERFORMANCE ENHANCEMENTS
New features in Firmware Revision 6.01 include:
D Increased Low Speed Torque.
The parameter [IR Comp %] was added, allowing
adjustment of the amount of IR compensation desired. This
is used to compensate for stator resistance and allows much
higher levels of starting torque. The default levels of [Start
Boost] and operation of the [Compensation] parameter
have changed. The default setting for [Compensation] is
now “Comp” and functions from 1.1 to 120 Hertz.
D Improved Acceleration.
The acceleration current ramp regulator has been retuned
and the current feedback filter time constant was reduced,
allowing improved performance with short acceleration
times under all load conditions. The drive power-up
diagnostics were also shortened considerably, which
improves response time to a START signal. The parameter
[Adaptive I Lim] was also added for very quick
accelerations with low system inertias.
D Robust Current Limit.
A fast frequency foldback was added to operate with the
lower hardware current limit. This allows the drive to
continue operating under adverse conditions.
D Improved Speed Regulation.
The parameter [Rated Slip] was added, which compensates
for inherent slip in an induction motor. This assists in
maintaining an induction motor shaft frequency under
heavy loading conditions. The actual frequency value added
may be viewed in [Slip Comp Adder].
D Reduced Voltage Ring-up.
Voltage Ring-up Reduction Software is enabled when
[Cable Length] = “Long”. This software attempts to limit
voltage ring-up.
D Improved Drive Functionality.
The [Analog Filter] parameter was added. This allows
selection of the amount of software filtering applied to the
0-10 Volt and Potentiometer inputs in 25% increments. The
lower the percentage, the less filtering applied.
The Stop Mode “DC Brake” has been greatly improved by
incorporating a current limit function into this stopping
mode.
The parameter [DC Hold Time] is now settable up to 150
seconds in 0.1 second increments and [Maximum Voltage]
is now settable to 110% of the drive rating. Several
additional parameters now have new factory default values.

INPUT DEVICES
Starting and Stopping the Motor
ATTENTION: The drive start/stop control circuitry
includes solid-state components. If hazards due to
!
accidental contact with moving machinery or
unintentional flow of liquid, gas or solids exist, an
additional hardwired stop circuit is required to remove
AC line power to the drive. When AC input power is
removed, there will be a loss of inherent regenerative
braking effect and the motor will coast to a stop. An
auxiliary braking method may be required.
Repeated Application/Removal of Input Power
ATTENTION: The drive is intended to be controlled
by control input signals that will start and stop the motor.
!
A device that routinely disconnects then reapplies line
power to the drive (input contactor, etc.) for the purpose
of starting and stopping the motor should not be used. If it
is necessary to use this method for starting and stopping or
if frequent cycling of power is unavoidable, make sure
that it does not occur more than once

Normal Operation: After the input contactor is closed, the
enable, start, and stop signals may be applied. These control
signals must be removed before opening the input contactor.
The input contactor must not be opened and closed more than
once a minute.
Bypass Contactors
ATTENTION: An incorrectly applied or
installed system can result in component damage

or reduction in product life. The most common
causes are:
D
Wiring AC line to drive output or control terminals.
D Improper voltage placed on control terminals.
D Improper bypass or output circuits not approved by
Allen-Bradley.
D Output circuits which do not connect directly to the
motor.
D Incorrect or inadequate AC supply.
D Excessive ambient temperature.

INPUT POWER CONDITIONING
The drive is suitable for direct connection to a correct voltage,
single phase or three-phase, AC power line. However, there are
certain power line conditions which may introduce the
possibility of drive input power component malfunction. To
reduce the possibility of these malfunctions, a line reactor or
isolation type transformer with an input impedance of 3% of
the drive input VA rating may be required.
The basic rules for determining if a line reactor or isolation
type transformer is required are as follows:
1. If the AC line supplying the drive has power factor
correction capacitors that are switched in and out, installing
an AC line reactor or isolation type transformer between the
capacitor bank and the drive input may be required. Damage
to drives can occur from the extreme current spikes caused
by capacitor switching.
2. If the AC line frequently experiences transient power
interruptions or significant voltage spikes, an AC line
reactor or isolation type transformer may be required.
Damage to drives can occur from extreme current spikes.

ELECTRICAL INTERFERENCE – EMI/RFI
Immunity
The 1305 drive is designed for immunity to most externally
generated interference. Usually, no special precautions are
required beyond the installation practices provided in this
publication.
It is recommended that the coils of DC energized contactors
associated with drives be suppressed with a diode or similar
device, since they can generate severe electrical transients.
In areas subject to frequent lightening strikes, additional surge
suppression is advisable.
Emission
Careful attention must be given to the arrangement of power
and ground connections to the drive to avoid interference with
nearby sensitive equipment. The cable to the motor carries
switched voltages and should be routed well away from
sensitive equipment.
The ground conductor of the motor cable should be connected
to the drive ground (GRD) terminal directly. Connecting this
ground conductor to a cabinet ground point or ground bus bar
may cause high frequency current to circulate in the ground
system of the enclosure. The motor end of this ground
conductor must be solidly connected to the motor case ground.
Shielded or armored cable may be used to guard against
radiated emissions from the motor cable. The shield or armor
should be connected to the drive ground terminal and the
motor ground as outlined in the Grounding section of this
Installation chapter.
Common mode chokes are recommended at the drive output to
reduce the common mode noise.
An RFI filter can be used and in most situations provides an
effective reduction of RFI emissions that may be conducted
into the main supply lines.
If the installation combines a drive with sensitive devices or
circuits, it is recommended that the lowest possible drive PWM
frequency be programmed.
2-8
efesotomasyon.com - Allen Bradley,Rockwell,plc,servo,drive
Installation/Wiring
RFI FILTERING
1305 drives can be installed with an RFI filter, which controls
radio–frequency conducted emissions into the main supply
lines and ground wiring.
If the cabling and installation recommendation precautions
described in this manual are adhered to, it is unlikely that
interference problems will occur when the drive is used with
conventional industrial electronic circuits and systems.
However, a filter is recommended if there is a likelihood of
sensitive devices or circuits being installed on the same AC
supply or if the motor cable exceeds 75 meters (250 feet).
Beyond this length, capacitance to ground will increase the
supply emissions.
Where it is essential that very low emission levels must be
achieved or if conformity with standards is required the
optional RFI filter should be used. Refer to Appendix D and
instructions included with the filter for installation and
grounding information.
RFI Filter Leakage Current
The optional RFI filter may cause ground leakage currents.
Therefore a solid ground connection must be provided.
ATTENTION: To guard against possible
!
equipment damage, RFI filters can only be used
with AC supplies that are nominally balanced
with respect to ground. In some installations,
three–phase supplies are occasionally connected
in a 3-wire configuration with one phase
grounded (Grounded Delta). The filter must not
be used in Grounded Delta supplies.
CE Conformity
Refer to Appendix D.
Installation/Wiring
efesotomasyon.com - Allen Bradley,Rockwell,plc,servo,drive
2-9
GROUNDING
Refer to the grounding diagram on the following page. The
drive must be connected to system ground at the power ground
(GRD) terminal provided on the power terminal block (TB1).
Ground impedance must conform to the requirements of
national and local industrial safety regulations (NEC, VDE
0160, BSI, etc.) and should be inspected and tested at
appropriate and regular intervals. In any cabinet, a single,
low–impedance ground point or ground bus bar should be used.
All circuits should be grounded independently and directly.
The AC supply ground conductor should also be connected
directly to this ground point or bus bar.
Sensitive Currents
It is essential to define the paths through which the high
frequency ground currents flow. This will assure that sensitive
circuits do not share a path with such current, and to minimize
the area enclosed by these paths. Current carrying ground
conductors must be separated. Control and signal ground
conductors should not run near or parallel to a power ground
conductor.
Motor Cable
The ground conductor of the motor cable (drive end) must be
connected directly to the ground terminal, not to the enclosure
bus bar. Grounding directly to the drive (and filter, if installed)
provides a direct route for high frequency current returning
from the motor frame and ground conductor. At the motor end,
the ground conductor should also be connected to the motor
case ground. If shielded or armored cables are used, the same
grounding methods should be used for the shield/armor as well.
Discrete Control and Signal Wiring
DO NOT connect drive Common terminals (TB2) to ground.
DO NOT switch these inputs using non-isolated TTL type
circuits. Use dry relay contacts to switch signal inputs to
Common. Only isolated 4-20mA sources are recommended.
There must be no ground potential difference between source
and drive.
Safety Ground
This is the safety ground required by code. The ground bus can
be connected to adjacent building steel (girder, joist) or a floor
ground loop, provided grounding points comply with NEC
regulations.
RFI Filter
Important: Using an optional RFI filter may result in
relatively high ground leakage currents. The filter must be
permanently installed and solidly grounded. Grounding must
not rely on flexible cables and should not include any form of
plug or socket that would permit inadvertent disconnection.
The integrity of this connection should be periodically
checked.

Installation/Wiring
Motor Cables
A variety of cable types are acceptable for drive installations.
For many installations, unshielded cable is adequate, provided
it can be separated from sensitive circuits. As an approximate
guide, allow a spacing of 1 meter (3.3 feet) for every 10 meters
(33 feet) of length. In all cases, long parallel runs must be
avoided.
The cable should be 4-conductor with the ground lead being
connected directly to the drive ground terminal (GRD) and the
motor frame ground terminal.
Shielded Cable
Shielded cable is recommended if sensitive circuits or devices
are connected or mounted to the machinery driven by the
motor. The shield must be connected to the drive ground and
motor frame ground. The connection must be made at both
ends to minimize the external magnetic field.
If cable trays or large conduits are to be used to distribute the
motor leads for multiple drives, shielded cable is recommended
to reduce or capture the noise from the motor leads and
minimize “cross coupling” of noise between leads of different
drives. The shield should be connected to the ground
connections at both the motor and drive end.
Armored cable also provides effective shielding. Ideally, it
should be grounded only at the drive (GRD) and motor frame.
Some armored cable has a PVC coating over the armor to
prevent incidental contact with grounded structure. If, due to
the type of connector, the armor must be grounded at the
cabinet entrance, shielded cable should be used within the
cabinet to continue as far as possible to the coaxial
arrangement of power cable and ground.
In some hazardous environments it is not permissible to ground
both ends of the cable armor. This is because of the possibility
of high current circulating at the input frequency if the ground
loop is cut by a strong magnetic field. This only applies in the
proximity of powerful electrical machines. In such case, the
ground connection at one end may be made through a
capacitance, which will block the frequency current but present
a low impedance to RF. Because of the highly pulsed nature of
the circulating current, the capacitor type used must be rated
for AC-to-ground voltage. Consult factory for specific
guidelines.
Installation/Wiring
efesotomasyon.com - Allen Bradley,Rockwell,plc,servo,drive
2-13
Conduit
If metal conduit is preferred for cable distribution, the
following guidelines must be followed.
1. Drives are normally mounted in cabinets and ground
connections are made at a common ground point in the
cabinet. If the conduit is connected to the motor junction
box and at the drive end, no further conduit connections are
necessary.
2. No more than three sets of motor leads can be routed
through a single conduit. This will minimize “cross talk”
that could reduce the effectiveness of the noise reduction
methods described. If more than three drive/motor
connections per conduit are required, shielded cable as
described above must be used. If practical, each conduit
should contain only one set of motor leads.
ATTENTION: To avoid a possible shock hazard
caused by induced voltages, unused wires in the
!
conduit must be grounded at both ends. For the
same reason, if a drive sharing a conduit is being
serviced or installed, all drives using this conduit
should be disabled. This will eliminate the
possible shock hazard from “cross coupled” drive
motor leads.
Motor Lead Lengths
Installations with long cable lengths between the 1305 drive
and motor may require the use of an output reactor or
Terminator. The following guidelines allow for selection of the
appropriate drive HP rating (and output reactor or Terminator,
if required) to work with an existing motor, and provide
motor-lead length solutions for new installations.
Voltage doubling at motor terminals, known as reflected wave
phenomenon, standing wave or transmission line effect, can
occur when using long motor cables with drives. Long motor
cables can cause capacitive charging current in excess of the
rating of a smaller drive. To ensure proper installation, follow
the guidelines provided.
All cabling and distances are based on using 14 AWG,
4-conductor type cabling.
In general, motors designed and built without phase separating
insulation paper between motor windings should be classified
as 1000V

Section B: Use of Output Reactor or Terminator
For longer motor-lead length applications, an output reactor or
Terminator is required to ensure proper drive operation, and for
the motor to operate within its specified insulation rating. The
guidelines in Table 2.E are required for proper drive and motor
operation, or motor designs without phase-separating insulation
paper between motor windings.
Applications with non-inverter duty rated motors, with long
lead lengths, require an output reactor or Terminator. An output
reactor or Terminator helps reduce voltage reflection to the
motor to levels which are less than the motor insulation rating.
Table 2.E lists maximum cable lengths that can be run when
using an output reactor, or one of two available Terminators,
for motor insulation ratings of 1000V, 1200V, and 1600V.
Shielded and unshielded maximum cable lengths also are
listed.
When an output reactor is required, locate the reactor at the
drive if possible. Consult the factory for applications which
require mounting the reactor at the motor.
1000V and 1200V Motor Insulation Ratings: Cable lengths
listed in Table 2.E are for operating the 1305 drive at a
maximum carrier frequency of 2 kHz on motor insulation
ratings of 1000V and 1200V when used with an output reactor
or Terminator. Consult the factory regarding operation above 2
kHz carrier frequency. Multiply listed distances by 0.85 for
operation at high line conditions (above 480V).
1600V Motor Insulation Ratings: Cable lengths listed in
Table 2.E are based on operating the 1305 drive at a maximum
carrier frequency of 2 kHz on motor insulation ratings of
1600V. Consult the factory regarding operation above 2 kHz
carrier frequency.
The Allen-Bradley 1329-HR is representative of 1600V
P-P
insulation rating designs and is recommended in applications
where long cable lengths are required.
Example: An existing installation includes a 2 HP, 1200V
motor with a 84-meter (275-foot) cable-length requirement
between the 1305 drive and the motor. What are the possible
solutions to this installation?
1. Table 2.D indicates that either an output reactor or a
Terminator is required for this installation example. Consult
Table 2.E for output reactor, Terminator, and cable types.
2. Table 2.E suggests these possible solutions:
–
Install a 1305 2-HP drive with an output reactor installed at
the drive, and use unshielded cable.
– Install a 1305 3-HP drive with an output reactor installed at
the drive, and use shielded or unshielded cable.
– Install a 1305 2-HP drive with a 1204-TFA1 Terminator,
and use shielded or unshielded cable.
