Chapter 1 - Introduction

This chapter is a brief introduction to the TX Series soft starter and describes
product operation and unit features.

1.1 - General

The TX Series is a high-end digitally programmable solid state reduced voltage soft
starter. This heavy duty starter provides reduced voltage, stepless soft starting of
3-phase AC induction motors, protecting mechanical components from excessive
torque stress and electrical systems from the effects of high motor inrush currents.
The TX Series includes advanced motor and load protection features just like those
found in expensive motor protection relays. These include retentive thermal
memory, dynamic reset capacity, true thermal modeling, separate trip curves for
start and run protection, overload alarm, etc. In the case of the TX Series, these
features are built in as standard features, providing a cost effective and reliable
motor starting and protection scheme for your critical motor applications.

The TX Series features an easy to use interface operator for programming and
status indication. It includes a large tactile feedback keypad, LED status indica­tors and a 2 line x 20 character backlit display using plain English text readout. In
addition to programming the standard parameters such as starting torque, ramp
time, current limit, dual ramp and decel control, other features like programmable
overload trip curves (NEMA/UL Classes 5 - 30), starts-per-hour, time between
starts and coast down/back spin lockout protection can also be programmed for
your specific application needs.

TX Series 48 - 1250A

1.3 - Theory of Operation

The power of the TX Series is in the CPU, a microprocessor based
protection and control system for the motor and starter assembly.
The CPU uses Phase Angle Firing of the SCRs to apply a reduced
voltage to the motor, and then slowly and gently increases torque
through control of the voltage and current until the motor accelerates
to full speed. This starting method lowers the starting current of the
motor, reducing electrical stresses on the power system and motor.
It also reduces peak starting torque stresses on both the motor and
load mechanical components, promoting longer service life and less
downtime.

Acceleration: The TX Series comes standard with several methods of
accelerating the motor so that it can be programmed to match almost
any industrial AC motor application.

The factory default setting applies a Voltage Ramp with Current Limit
as this has been proven the most reliable starting method for the vast
majority of applications. Using this starting method, the Initial Torque
setting applies just enough voltage to the motor to cause the motor shaft
to begin to turn. This voltage is then gradually increased over time (as
per the Ramp Time setting) until one of three things happen: the motor
accelerates to full speed, the Ramp Time expires or a Current Limit
setting is reached.

If the motor accelerates to full speed before the ramp time setting has
expired, an automatic Anti-Oscillation feature will override the remaining
ramp time and full voltage will be applied. This will prevent any surging
or pulsation in the motor torque, which might otherwise occur due to the
load not being fully coupled to the motor when operating at reduced
voltage and torque levels.

If the motor has not reached full speed at the end of the ramp time
setting, the current limit setting will proportionally control the maximum
output torque. Feedback sensors in the TX Series provide protection
from a stall condition, an overload condition or excessive acceleration
time.

The Current Limit feature is provided to accommodate installations
where there is limited power available (for example, on-site generator
power or utility lines with limited capacity). The torque is increased
until the motor current reaches the preset Current Limit point and it is
then held at that level. Current Limit overrides the ramp time setting
so if the motor has not accelerated to full speed under the Current
Limit setting, the current remains limited for as long as it takes the
motor to accelerate to full speed.

When the motor reaches full speed and the current drops to running
levels, the TX Series detects an At-Speed condition and will close the
Bypass Contactor (if provided). The Bypass Contactor serves to shunt
power around the SCR stack assemblies to prevent heat build-up
NEMA 12, 3R, 4 and 4X enclosed units due to the slight voltage drop
across the SCRs. At this point, the TX Series has the motor operat-
ing at full voltage, just as any other starter would.

TOSHIBA - 4

TX Series 48 - 1250A

Other starting methods available in the TX Series are:

· Current Ramp: uses a closed current feedback PID loop to provide a linear
torque increase up to a Maximum Current level.

· Constant Current: current is immediately increased to the Current Limit point
and held there until the motor reaches full speed.

· Custom Curve: gives the user the ability to plot torque and time points on a
graph. The soft starter will then accelerate the motor following these points.

· Tachometer Feedback Ramp: uses a closed loop speed follower method
monitoring a tachometer input signal from the motor or load shaft. (PENDING)

Deceleration: the TX Series provides the user with the option of having the
load coast to a stop or controlling the deceleration by slowly reducing the voltage
to the motor upon initiating a stop command. The Decel feature is the oppo-
site of DC injection braking in that the motor will actually take longer to
come to a stop than if allowed to coast to a stop. The most common applica­tion for the Decel feature is pumping applications where a controlled stop
prevents water hammer and mechanical damage to the system.

1.4 General Protection

Operation of the TX Series can be divided into 4 modes; Ready, Start, Run and
Stop. The CPU provides motor and load protection in all four modes. Additional
details on each protection feature can be found in later chapters.

Ready Mode: In this mode, control and line power are applied and the starter is
ready for a start command. Protection during this mode includes the monitor­ing of current for leakage through multiple shorted SCRs. Other protection
features in effect are:

· Starter Temperature

· Shorted SCR

· Phase Reversal (if enabled)

· Line Frequency Trip Window

· External Input Faults

Note: The “Programming Mode” can only be entered from the Ready Mode.
During programming, all protection features and start command are disabled.

Start Mode: These additional protection functions are enabled when the soft
starter receives a valid Start command:

· Phase Reversal (if enabled)

· Start Curve

· Acceleration Timer

· Phase Imbalance

· Short Circuit / Load Pre-check (Toe-in-the-Water)

· Ground Fault

· External Input Faults

· Accumulated Starting FLA Units (I2t Protection)

· Overload Protection

· Thermal Capacity

Note: Shorted SCR and Shunt Trip protection are no longer in effect once the
soft starter goes into the Start Mode.

Run Mode: The soft starter enters the Run Mode when it reaches full output
voltage

Mode these additional protection features are enabled:

· Running Overload Curve

· Phase Loss

· Under Current / Load Loss

· Over Current / Electronic Shear Pin

· External Input Faults
Stop Mode: Once a Stop command has been given, the TX Series protec-

tion features change depending on which Stop Mode is selected.

when the stop command is given include:

1.5 Thermal Overload Protection

The TX Series plays an important role in the protection of your motor in that it
monitors the motor for excessive thermal conditions due to starting, running or even
ambient conditions. The TX Series has a Dynamic Thermal Register system in
the CPU that provides a mathematical representation of the thermal state of the
motor. This thermal state information is kept in memory and is monitored for
excesses in both value and rate of change. Input is derived from current
imbalances and (optional) RTD measurements making it dynamic to all processes
involving the motor. The TX Series monitors these conditions separately during
Start and Run modes to provide proper thermal overload protection at all times.

Start Mode overload protection is selectable using one of three methods:

· Basic Protection: I2t data is accumulated and plotted based on an Overload
Curve selected in programming. This is programmed per NEMA Class 5-30
standard curves and is based on the Locked Rotor Current (from the motor
nameplate) as programmed into the soft starter.

· Measured Start Capacity: the user enters a measured amount of thermal
capacity from a pre-selected successful start as a setpoint to the Thermal
Register for the soft starter to follow.

· Learned Curve Protection: the user sets the soft starter to the “LEARN” mode
and starts the motor under normal starting conditions. The CPU then
samples and records 100 data points during the start curve, analyzes them
and creates a graphical representation in memory. The soft starter is then
switched to Curve Follow protection mode and monitors motor performance
against this curve. This feature is especially useful in initial commissioning
tests to record a base line performance sample (in this case, it is not
necessarily used for motor protection).

TOSHIBA - 6

TX Series 48 - 1250A

Run Mode overload protection is initiated when the TX Series determines
that the motor is At-Speed. Overload Protection is initiated when the motor
RMS current rises above a “pick-up point” (as determined by the motor
nameplate FLA and service factor). Run mode protection is provided by the
CPU monitoring the Dynamic Thermal Register. Data for the Dynamic
Thermal Register is accumulated from I
trip occurs when the register reaches 100% as determined by the selected
Overload Protection Curve (NEMA Class 5-30 standard curves) and is based
on the programmed Locked Rotor Current indicated on the motor nameplate.
The Dynamic Thermal Register is altered, or “biased”, by the following condi­tions:

· Current Imbalance: will bias the register higher to add protection from
additional motor heating during a current imbalance condition.

· Normal Cooling: provided when the motor current drops below the pick-up
point or the motor is off line. The cooling rate is lower for motors that are off­line (such as after a trip) since cooling fans are also inoperative.

· RTD Input: (requires the optional RTD monitor card): will bias the register in
either direction based on real-time input of the motor, bearing and even
ambient temperature conditions.

t calculations and cooling rates. A

· Dynamic Reset is another feature that adds reliability and consistency to the
performance of the TX Series soft starter. If a motor overload condition
occurs and the soft starter trips, it cannot be reset until sufficient cool down
time has elapsed. This cool down time is determined by the thermal state of
the motor when it tripped (i.e. hot motors cool more quickly due to additional
convection). The cool down time is also biased by RTD measurements when
used.

Retentive Thermal Memory provides continuous overload protection and real
time reset even if power is lost. Upon restoration of power, the TX Series will
read the Real Time Clock and restore the thermal register to what it should be
given the elapsed time.

· Learned Reset Capacity is a feature that is unique to the TX Series. By
sampling the amount of thermal capacity used in the previous three successful
starts, the TX Series will not allow a reset until a sufficient amount of
thermal capacity has been regained in the motor. This prevents nuisance
tripping and insures that unsuccessful start attempts (which would otherwise
use up the starts-per-hour capacity of the motor) are not allowed.

WARNING

Chapter 2 - Installation

2.1 Receiving and Unpacking

Upon receipt of the unit:

• Carefully unpack the unit and inspect it for any shipping damage.
Report any damage immediately and file a claim with the freight
carrier within 15 days of receipt.

• Verify that the model number on your unit matches your purchase
order.

• Confirm that the ratings label on the unit matches or is greater than
the motor’s HP and current rating.

2.2 Initial Unit Inspection

• Make a complete visual check of the unit for damage which may have
occurred during shipping and handling. Do not attempt to continue
installation or start up the unit if it is damaged.

• Check for loose mechanical assemblies or broken wires which may
have occurred during transportation or handling. Loose electrical
connections will increase resistance and cause the unit to function
improperly.

• Prior to beginning the installation, verify that the motor and TX unit
are rated for the proper amperage and voltage.

2.3 Location

The proper location of the unit is an important factor in achieving the
unit’s specified performance and normal operation lifetime. The unit
should always be installed in an area where the following conditions
exist:

• Ambient Operating Temperature: 0° C to 50° C (32° F to 122° F)
(Optional space heaters can be provided for operation in ambient
temperature to -20° C.)

• Protected from rain and moisture.

• Humidity: 5% to 95% non-condensing.

• Free from metallic particles, conductive dust and corrosive gas.

• Free from excess vibration (below 0.5G)

• Open panel units must be mounted in the appropriate type of
enclosure. Enclosure size and type must be suitable to dissipate
heat generated by the soft starter. Contact factory for assistance in
sizing the enclosure.

Do not service equipment with voltage applied!
The unit can be the source of fatal electrical
shocks! To avoid shock hazard, disconnect
main power and control power before working
on the unit. Warning labels must be attached
to terminals, enclosure and control panel to
meet local codes.

2.4 Mounting and Cleaning

When drilling or punching holes in the enclosure, cover the electrical
assembly to prevent metal filings from becoming lodged in areas which
can cause clearance reduction or actually short out electronics. After
work is completed, thoroughly clean the area and reinspect the unit for
foreign material. Make sure there is sufficient clearance (six inches)
all around the unit for cooling, wiring and maintenance purposes. To
maximize effective air flow and cooling, the unit must be installed with
its heat sink ribs oriented vertically and running parallel to the mounting
surface.

2.7 Power Connections

Connect appropriate power lines to the unit input terminals marked L1, L2, L3.
Avoid routing power wires near the control board. Connect the motor leads to the
unit terminals marked T1, T2, T3. Refer to NEC standards for wire length and sizing.
Never interchange input and output connections to the unit. This could cause
excessive voltage in the control logic circuit and may damage the unit.

TX Series Unit

Never connect power factor correction
capacitors on the load side of the unit.
The SCRs will be seriously damaged if
capacitors are located on the load side.

The unit must be tested with a motor or other test load connected
to the load side of the unit. (A load bank can be used if a motor is
not available). Note that line voltage will appear across the output terminals if
there is no motor or load connected to the unit. In areas where lightning is a
significant problem, station-type air gap lightning arrestors should be considered
and utilized on the input power source.

2.7.1 Grounding

Connect the ground cable to the ground terminal as labeled on the unit. Refer
to the National Electrical Code for the proper ground wire sizing and be sure
that the ground connector is connected to earth ground.

2.8 Control Connections

Separate 120Vac supply is required (240Vac for 380V and 415V
applications). The control voltage should be connected to pins 1 and 6 of
TB4 on the power board. This control voltage must be customer supplied,
unless an optional control power transformer (See chart) has been supplied
with the unit.

WARNING

2.8.2 Two-Wire Connection

An alternate connection for unattended operation replaces start/stop push
buttons by connecting a maintained contact closure between pins 3 and
5 on TB4. When the maintained contact is used for start/stop it is
necessary to set the overload setpoint to the manual reset position.
This will prevent the motor from restarting if the thermal overload trips
and then cools off.

Two-Wire Connection

When two-wire connection method is used, the start
circuit must be interlocked to prevent automatic
restart when either of the two protective devices
(overload or thermostat) reset. Thermostats always
automatically reset on cool down.

2.8.3 Programmable Relays/Relay Contacts

All the relay contacts are FORM C (Com, N.O., N.C.). Toshiba recommends
fusing all contacts with external fuses. The TX has four programmable relays
on TB3 on the power board. The relays are rated for 240Vac, 5 A and 1200
VA. These relays can respond to either a fault condition or an up-to-speed
condition. In the TX all tripping functions have been assigned to the TRIP
(AUX1) relay, and all alarm (warning) condition has been configured to the
ALARM (AUX2) relay. AUX 3 is factory programmed for a SHUNT TRIP
indication and can be connected to a shunt trip coil on an incoming circuit
breaker or open an input isolation contactor. AUX4 is the AT SPEED contact.
When the motor has reached the end of its acceleration ramp, the TX will
wait until the AT SPEED programmed time delay has expired. Then, the
relay will energize until a stop command has been received. The AT SPEED
contact can be used to operate a bypass contactor (used for shorting the
load current around the SCRs. To change AUX3 or AUX4 functions, see
Setpoint Page 4.

WARNING

Chapter 3 - Start-up

THE TX UNIT DEALS WITH POTENTIALLY LETHAL
VOL T AGE LEVELS. YOU MUST BE CERT AIN THA T
PERSONNEL ARE THOROUGHL Y TRAINED IN THE
APPLICABLE SAFETY PRECAUTIONS BEFORE
PROCEEDING WITH THIS SECTION!

3.1 Preliminary Start-Up Check List

Please make the following checks before applying power to the unit:

• Supply voltage matches the rated supply voltage of the unit.

• Horsepower and current ratings of the motor and unit match or the unit has a
higher rating.

• Initial ramp time and torque adjustments have been checked.

• Power lines are attached to the unit input terminals marked L1, L2 and L3.

• Motor leads are connected to the lower terminals marked T1, T2 and T3.

• Appropriate control power is applied and/or control connections have been
made.

• The motor’s FLA has been programmed.

• The thermal overload parameters are properly set.

• The motor area and equipment are clear of people and parts before start-up.

3.2 Introduction

It is best to operate the motor at its full load starting condition to achieve the
proper time, torque and ramp settings. Initial settings are set to accommo­date most motor conditions. TRY INITIAL SETTINGS FIRST. See Setpoints
Page 2 to make any adjustments.

3.3 Acceleration Adjustments

The unit is set at the factory with typical starting characteristics that perform well
in most applications. When the system is ready to start, try the initial unit
settings. If the motor does not come up to speed, increase the current limit
setting. If the motor does not start to turn as soon as desired, raise the
starting voltage adjustment. Adjustment description and procedures are
described as follows (See section 4.5.2 for additional Accel settings):

3.3.1 Starting Voltage

Factory Setting = 20% of line voltage
Range = 0% - 100% of line voltage

Starting voltage adjustment changes the initial starting voltage level to the
motor.

3.3.2 Ramp Time

Factory Setting = 10 sec.
Range = 0 - 120 sec.

Ramp time adjustment changes the amount of time it takes to reach the
current limit point or full voltage if the current limit point was not reached.

3.3.3 Current Limit

Factory Setting = 350% of unit FLA
Range = 200% - 600% of unit FLA

The current limit adjustment is factory set for 350% of the unit’s rating.
The range of adjustment is 200% to 600%. The main function of current
limit is to cap the peak current. It may also be used to extend the ramp­ing time if required. The interaction between the voltage ramp and the
current limit will allow the soft start to ramp the motor until the maximum
current is reached and the current limit will hold the current at that level.

TOSHIBA - 16

TX Series 48 - 1250A

The current limit must be set high enough to allow the motor to
reach full speed. The factory setting of 350% is a good starting
point. Do not set the current limit too low on variable starting

loads. This could cause the motor to stall and eventually
cause the overload protection to trip.

3.4 Deceleration Adjustments (Pump Control)

Decel extends the stopping time on loads that would otherwise stop
too quickly if allowed to coast to stop. Decel control provides smooth
deceleration until the load comes to a stop. Three adjustments
optimize the deceleration curve to meet the most demanding require­ments. Try factory settings before adjusting.

Deceleration Applications
The unit is shipped from the factory with the decel feature
disabled. Apply power and adjust the soft start before enabling or

modifying the deceleration adjustments. Both acceleration and deceleration
adjustments should be made under normal load conditions.

The deceleration feature provides a slow decrease in the output voltage,
accomplishing a gentle decrease in motor torque during the stopping mode.
This is the OPPOSITE OF BRAKING in that it will take longer to
come to a stop than if the starter were just turned off. The primary use
of this function is to reduce the sudden changes in pressure that are
associated with “Water Hammer” and slamming of check valves with
centrifugal pumps. Decel control in pump applications is often referred
to as Pump Control.

In a pump system, liquid is being pushed uphill. The force exerted by
gravity on the column of liquid as it goes up hill is called the “Head
Pressure” in the system. The pump is sized to provide enough Output
Pressure to overcome the Head Pressure and move the fluid up the
pipe. When the pump is turned off, the Output Pressure rapidly drops
to zero and the Head Pressure takes over to send the fluid back down
the hill. A “Check Valve” is used somewhere in the system to prevent
this (if necessary) by only allowing the liquid to flow in one direction.
The kinetic energy in that moving fluid is suddenly trapped when the
valve slams closed. Since fluids can’t compress, that energy is
transformed into a “Shock Wave” that travels through the piping
system looking for an outlet in which it dissipates. The sound of that
shock wave is referred to as “Water Hammer”. The energy in that
shock wave can be extremely damaging to pipes, fittings, flanges,
seals and mounting systems.
By using the Soft Stop/Deceleration feature of the TX, the pump output
torque is gradually and gently reduced, which slowly reduces the
pressure in the pipe. When the Output Pressure is just slightly lower
than the Head Pressure, the flow slowly reverses and closes the
Check Valve. By this time there is very little energy left in the moving
fluid and the Shock Wave is avoided. When the output voltage to the
motor is low enough to no longer be needed, the TX will end the Decel
cycle and turn itself off.

TOSHIBA- 17

TX Series 48 - 1250A

WARNING

Another common application for decel control is on material handling convey­ors as a means to prevent sudden stops that may cause products to fall over
or to bump into one another. In overhead crane applications, soft stopping of
the Bridge or Trolley can prevent loads from beginning to over swing on
sudden stops.

3.4.1 Start Deceleration Voltage

Factory Setting = 60% of line voltage
Range = 0% - 100% of line voltage

The step down voltage adjustment eliminates the dead band in the
deceleration mode that is experienced while the voltage drops to a level
where the motor deceleration is responsive to decreased voltage. This
feature allows for an instantaneous drop in voltage when deceleration is
initiated.

3.4.2 Stop Deceleration Voltage

Factory Setting = 20% of line voltage
Range = 0% - 100% of line voltage

The stop voltage level setpoint is where the deceleration voltage drops
to zero.

3.4.3 Deceleration Time

Factory Setting = 5 sec.
Range = 0 - 60 sec.

The deceleration ramp time adjusts the time it takes to reach the stop
voltage level set point. The unit should be restarted and stopped to verify
that the desired deceleration time has been achieved.

DO NOT EXCEED THE MOTOR MANUF ACTURER’S
RECOMMENDED NUMBER OF ST ARTS PER HOUR.
WHEN CALCULA TING THE NUMBER OF ST ARTS PER
HOUR, A DECEL CURVE SHOULD BE COUNTED AS A
START CUR VE. FOR EXAMPLE: RECOMMENDED
NUMBER OF ST ARTS PER HOUR = 6, ALLOW ABLE
ST ARTS WITH DECEL CYCLE PER HOUR = 3.

3.5 Sequence of Normal Operation

• Apply control power and check that the “Power” LED comes on.
(Display 1)

• Apply three phase power to the unit. The motor should run only when the
start command is applied.

• Apply the start command. (Display 2). The RUN LED will be lit. (Display 3)
The AUX3 LEDs will be lit. If the motor does not enter run mode in the set
time, a trip will occur.

• The POWER, RUN, AUX3 LEDs will be lit, indicating that the contact has
energized. IA, IB, IC will display the current setting for Phase A, Phase B,
and Phase C and the G/F indicates ground fault. (Display 4)

• When the motor reaches full speed, the “AUX4” LED (At Speed) will be lit.

• If the motor decelerates, or stops, during the acceleration period, hit the
stop button immediately and open the disconnect line. If the unit does not
follow this operational sequence, please refer to the Troubleshooting
Chapter.

It is best to operate the motor at its full load starting condition to achieve the
proper time, torque and ramp settings. Initial settings are set to accommodate
most motor conditions. TRY INITIAL SETTINGS FIRST. See Setpoint Page 2
to make any adjustments.

TX Series 48 - 1250A

SP.2 Starter Configuration (Setpoint Page 2)

Provides multiple choices for starting ramps that can be
selected for particular loads and applications.

SP2.1 Start Control Mode: Dual Ramp, Custom

Accel Curve, Tach Ramp, Jog Voltage, Start
Ramp 1, Start Ramp 2.

• Dual Ramp: The dual ramp mode works in
conjunction with External Input #3. This allows
the user to switch between the two start ramps
without having to reconfigure the start mode.
(For details on configuring External Input #3 for
DUAL RAMP see Setpoint Page 6.)

• Custom Accel Curve: Allows the user to
custom design the acceleration start curve to
the application. (See setpoint page 7 for
configuration setup.) Note: If Custom Accel
Curve has not been enabled in setpoint page 7,
the TX will ignore the start control mode and
read this setpoint as disabled.

• Tach Ramp: See setpoint page 6 for
configuration setup of tachometer input.
(Pending)

SP2.2 Jog Voltage: The voltage level necessary to

cause the motor to slowly rotate.

SP2.3 Start Ramp 1 Type: The ramp type can be

setup for either Voltage or Current. If Voltage is
selected, initial voltage, ramp time and current
limit are adjustable. If Current is selected, initial
current, ramp time and maximum current are
adjustable.

Start Ramp 1 Type: Voltage

• Voltage Ramping is the

most reliable starting
method, because the
starter will eventually
reach an output voltage
high enough to draw full
current and develop full
torque. This method is
useful for applications
where the load
conditions change
frequently and where
different levels of torque
are required. Typical applications include
material handling conveyors, positive
displacement pumps and drum mixers.
Voltage is increased from a starting point (Initial
Torque) to full voltage over an adjustable period
of time (Ramp Time). To achieve Voltage
Ramping, select VOLTAGE for the START RAMP
#1 TYPE setpoint and set CURRENT LIMIT #1
setpoint to 600% (the maximum setting). Since

this is essentially Locked Rotor Current on most
motors, there is little or no Current Limit effect on
the Ramp profile.

• Voltage Ramping with Current Limit is the most
used curve and is similar to voltage ramping.
However, it adds an adjustable maximum current
output. Voltage is increased gradually until the
setting of the Maximum Current Limit setpoint is
reached. The voltage is held at this level until
the motor accelerates to full speed. This may
be necessary in applications where the
electrical power is limited. Typical applications
include portable or emergency generator
supplies, utility power near the end of a
transmission line and utility starting power
demand restrictions. Note: Using Current Limit
will override the Ramp Time setting if necessary,
so use this feature when acceleration time is
not critical. To achieve Voltage Ramping with
Current Limit, select VOLTAGE for the START
RAMP #1 setpoint and set CURRENT LIMIT #1
setpoint to a desired lower setting, as
determined by your application requirements.

Start Ramp 1 Type: Current
Current Ramping (Closed Loop Torque

Ramping) is used for smooth linear acceleration
of output torque. Output voltage is constantly
updated to provide the linear current ramp, and
therefore the available torque is maximized at
any given speed. This is for applications where
rapid changes in torque may result in load
damage or equipment changes. Typical
applications include overland conveyors if belt
stretching occurs; fans and mixers if blade
warping is a problem; and material handling
systems if stacked products fall over or break.

This feature can be used with or without the

Maximum Current Limit setting. To achieve
Current Ramping select CURRENT for START
RAMP #1 TYPE setpoint and the MAXIMUM
CURRENT #1 setpoint to the desired level.

Current Limit Only: (Current Step) start uses
the Current Limit feature exclusively. This
method of starting eliminates the soft start
voltage/current ramp and instead, maximizes
the effective application of motor torque within
the limits of the motor. In this mode, setpoint
RAMP TIME #1 is set to zero (0), so the output
current jumps to the current limit setting
immediately. Typically used in with a limited
power supply, when starting a difficult load such
as a centrifuge or deep well pump, when the
motor capacity is barely adequate (stall
condition or overloading occurs) or if other
starting modes fail. Since ramp times are set to
zero (0). START RAMP #1 TYPE is set to

TOSHIBA- 35

TX Series 48 - 1250A

either VOLTAGE or CURRENT.

• Initial Torque (Initial Voltage #1 or Initial
Current #1): Sets the initial start point of either

the Voltage Ramp or the Current Ramp. Every
load requires some amount of torque to start from
a standstill. It is inefficient to begin ramping the
motor from zero every time, since between zero
and the WK2 break-away torque level, no work is
being performed. The initial torque level should
be set to provide enough torque to start rotating
the motor shaft, enabling a soft start and
preventing torque shock damage. Setting this
start point too high will not damage the starter,
but may reduce or eliminate the soft start effect.

• Ramp Time #1: Sets the maximum allowable
time for ramping the initial voltage or current
(torque) setting to either of the following:

1) the Current Limit setting when the motor is still
accelerating, or

2) full output voltage if the Current Limit is set to
maximum.
Increasing the ramp time softens the start
process by gradually increasing the voltage or
current. Ideally, the ramp time should be set for
the longest amount of time the application will
allow (without stalling the motor). Some
applications require a short ramp time due to the
mechanics of the system. (i.e., centrifugal
pumps, because pump problems can occur due
to insufficient torque).

SP2.4 Start Ramp 2: The same options and screen

setups as Start Ramp 1. Note: CUSTOM
ACCEL CURVE overrides the voltage or current
start in Ramps 1 and 2 when selected to be the
start control mode.

SP2.5 Kick Start: Used as an initial energy burst in

applications with high friction loads.

• Kick Start Voltage: The initial voltage (as a
percent of full voltage value) that is needed to
start the motor (i.e. Breakaway or Initial Torque).

• Kick Start Time: The time the initial torque
boost is applied.

SP2.6 Deceleration: Allows the motor to gradually

come to a soft stop.

• Start Deceleration Voltage: The first part of
the deceleration ramp. The TX initially drops to
this voltage level upon receiving a STOP
command. (Represented as a percent of
voltage value.)

• Stop Deceleration Voltage: The drop-off point
of the deceleration ramp. (Percent of voltage
value.)

• Deceleration Time: Decel ramp time.

• Current Limit: Sets the maximum motor

current the starter will allow during Ramping. As
the motor begins to ramp, the Current Limit
feature sets a ceiling at which the current draw
is held. Current Limit remains in effect until the
following occurs:

1) the motor reaches full speed (detected by the
At-Speed detection circuit) or

2) the Overload Protection trips on Motor Thermal
Overload.
Once the motor reaches full speed, the Current
Limit feature becomes inactive.

In the Voltage Ramp Profile, the voltage output is
increased until it reaches the Current Limit. Ramp
time is the maximum amount of time it takes for
the voltage to increase until the Current Limit
setting takes over. With some load conditions,
the Current Limit is reached before the Ramp
Time expires.

The Current Ramp profile varies the output
voltage to provide a linear increase in current up
to the Maximum Current setpoint value. A closed
loop feedback of motor current maintains the
Current Ramp profile.

SP2.7 Timed Output: Used with an AUX relay. When

enabled, and upon a start command, it energizes
the assigned relay for the programmed time. At
the end of the programmed time the relay de­energizes. See Setpoint Page 4.

SP2.8 Run Delay Time: Used with an AUX3 relay.

When enabled, and upon a start command, it
waits until the programmed time has expired.
The relay energizes and remains so until a stop
command is received. It de-energizes upon
receiving a stop command. See Setpoint Page

4.

SP2.9 At Speed Delay Time: Used with an AUX4 relay,

it waits until after the motor reaches the end of
ramp and the programmed delay time has
expired. The relay energizes until a stop
command has been received. See Setpoint Page

4.

SP5.1 When a relay has been configured as fail-safe

and power is applied, the relay will be
energized. The relay will then de-energize
when an event occurs or if the power fails.
NOTE: The relays in the TX will not prevent a
start sequence unless they are wired in as
interlocks. If power is lost, the motor power
is also lost.

SP5.2 A relay configured as non-latching will reset

itself when the cause of the trip event is not
continuous. The TRIP (AUX1) relay should

always be programmed for latching, because
this trip should require a visual inspection of
the motor and starter before issuing a
manual reset to release the relay after a trip
has been stored.

SP.6 User I/O Configuration (Setpoint Page 6)
(Security Level: 2)

The TX can be configured to accept a tachometer
feedback signal through the 4-20mA input and has two
options available for scaling the tachometer input. Note:
At the time of this printing, SP6.1 - SP6.4 are pending.

SP6.1 The first screen of setpoint page 6 is

TACHOMETER SCALE SELECTION. When
this is set to AUTO, the display prompts the
user to program the TX to sense when the
motor speed is zero. It will prompt again when
the motor speed is at maximum RPM. Once
these inputs are given, the TX automatically
scales the range of the tachometer feedback to
give a linear RPM ramp. When this is set to
MANUAL, the user will need to input the
tachometer scale of the 4-20mA input range.

• Press Enter if Motor Speed = 0 RPM: This
setpoint will be displayed when the user has
selected Auto Scaling Mode. The TX is
prompting the user to program when the motor
speed is at zero. This will be the lowest value
on the scale.

• Press Enter if Motor Speed = MAX RPM: The
TX is now prompting the user to program the
unit when the motor is at maximum speed. This
will be the highest value on the scale.

SP6.5 The TX provides two 4-20mA analog outputs.

Each analog output is independent of the other
and can be assigned to monitor different
functions. The available output ranges are
RPM, Hottest Non-Stator (Bearing) RTD,
Hottest Stator RTD, RMS current, or % Motor
Load.

• Analog Output #1 – Select a function from the
available five options to be transmitted from the
4-20mA output. Note: If selecting RPM, the
Tachometer feedback input signal must be
present in order for the TX to give proper
output. If selecting RTD, the RTD option must
be installed and an RTD input signal must be
present for a proper output to be given from the
analog output.

• Analog Output #1 4 mA: Enter a value that the
4mA level will represent for the selected
function; typically this value should be 0.

• Analog Output #1 20 mA: Enter a value that the
20mA level will represent for the selected
function.

SP6.6 Analog Output #2 – All of the setpoints and

setup screens for Analog Output #2 are the
same as those for Analog Output #1.

• Press Enter to Scale: This is a prompt to the
user that the unit has recorded the values of the
tachometer input based on input from the user
and is now ready to automatically scale the range
of the tachometer input.

• Manual Tach Scale 4.0 mA: The unit is looking
for an RPM value to assign to the lowest point on
the scale. This value should represent the
motor at zero speed.

• Manual Tach Scale 20.0 mA: The unit is looking
for an RPM value to assign to the highest point
on the scale. This value should represent the
motor at full speed.

SP6.2 Feedback Ramp Time: This is the duration of

the tachometer ramp time.

SP6.3 T ach Accel Trip: The maximum allowed

percentage of slip per NEMA design of the motor.

SP6.4 T ach Accel Trip Delay: The duration of time that

the Tach Accel trip condition must persist before
a trip is generated.

be set as either a normally open or normally
closed contact.

• External Input #1 Time Delay: Upon a change in
contact setting, the unit will wait the programmed
amount of time before generating an output. If
no delay is needed, then input 0 seconds. The
TX will post an event upon seeing a change in
state.

• External Input #2: The setup screens and
setpoints for External Input #2 includes the option
of programming the unit for Under Voltage Phase

• External Input #3: The setup screens and
setpoints for External Input #3 includes the option
of being configured for Dual Ramp. In Dual
Ramp mode, the initial contact setting is the
same as the START RAMP #1. Upon a change
in input contact state, the TX will switch over to
START RAMP #2 and use that setting for start
control mode. Note: The start RAMP types
should only be switched while the motor is
stopped. In Setpoint Page 4 Relay
Assignments, do not assign any output relay to
this function. The TX will ship with External
input #3 programmed for dual ramp. If it is not
needed, disable the dual ramp.

• External Input #4 – These input screens are for
the thermostat input and can be enabled or
disabled. Note: Toshiba recommends that this

function remain enabled. If the thermostat
indicates an over temperature condition, the TX
will trip the motor.

SP.7 Custom Acceleration Curve (Setpoint Page 7)
(Security Level: 3)

SP7.1 Setpoint Page 7 allows the user to custom

design the acceleration curve (start curve) to the
specific application. The user can custom
design up to three different curves in the TX.
Only one curve can be active (enabled) at a
time. Each of the three curves has eight voltage
levels, with corresponding ramp times and a
current limit setting.
Note: Each successive voltage level must be
programmed to a voltage level equal to or greater
than the previous level. All eight levels of
voltages must be programmed and the eighth
level has been preset at 100%.

• If Custom Accel Curve has been set to curve A, B
or C on this page, the TX will override the Start
Control Mode selected in Setpoint Page 2, (even
if Start Control Mode in Setpoint Page 2 has not
been set to Custom Accel Curve).

CURVE CONFIGURATION

BASIC RUN
OVERLOAD CURVE

Configures the unit’s start and run
protection mode. The unit has
independent start and run curve
protection and the settings can be
based on the OL Class or set by the
motor’s locked rotor current and time.

BASIC START
OVERLOAD CURVE

SP8.1 Basic Run Overload Curve

• Run Curve Locked Rotor

Time: Set the locked rotor

time to the OL Class default
chosen in Setpoint Page 1 or
set the time in seconds.
This is the time the locked
rotor condition exists before a
trip occurs.

• Run Locked Rotor Current:
The current the motor draws
with full voltage on the
windings and no rotor
movement (as a percent of
motor FLA). Refer to the
nameplate data or contact the
motor manufacturer.

AREA UNDER CURVE
PROTECTION: DISABLED

Range: ENABLED or DISABLED

• Coast Down Timer: If
enabled, this prevents the
motor from restarting for the
programmed amount of time,

CURRENT OVER
CURVE: DISABLED

Options: DISABLED, LEARN

or ENABLED

after a stop command is
given.

SP8.2 Basic Start Overload Curve

• Start Curve Locked Rotor Time: The locked rotor

time can be set to the OL Class default chosen in
Setpoint Page 1 or to a specific time. The
overload condition must exist for the programmed
amount of time before a trip occurs.

• Start Locked Rotor Current: The current the
motor draws with full voltage on the windings and
no motor movement (as a percent of motor FLA).
Refer to the motor nameplate data or contact the
motor manufacturer. See Appendix A.

• Acceleration Time Limit: If the motor does not
enter run mode (reach at speed) within the preset
time, the unit trips on acceleration time limit.

• Number of Starts per hour: If enabled, this limits
the maximum number of starts permitted per hour.
This setpoint allows a maximum of 6 starts per
hour. Contact motor manufacturer.

• Time Between Starts: If enabled, the TX
prevents another start attempt until the
programmed time has expired.

T allowed
during start. If the I2T to start exceeds this
number then the TX will generate a trip.

SP8.4 Current Over Curve: Learns the motor’s

starting characteristics and protects the motor
based upon the learned curve. It is useful
when commissioning a new motor.

• Learn: The unit reads the motor’s starting
characteristics. Start the motor and allow it
to come to full speed. The start feedback
enables the motor protection based on the
learned start curve.

• Learned Start Curve Basis: The maximum
allowed deviation above or below the start
curve before a trip is generated.

• Time for Sampling: The time the TX
continues to sample the start curve
characteristic during learn the mode.

TX Series 48 - 1250A

SP.9 RTD Configuration (Setpoint Page 9)
(Security Level: 3)

The TX is available with an optional RTD card that
provides 12 programmable RTDs which are individually
programmable for type. The available types are 100 ohm
platinum, 100 ohm nickel, 120 ohm nickel and 10 ohm
copper. Each RTD can be identified with a description
name of up to 15 characters (including spacing). Also,
each individual RTD has it own alarm and trip level.

SP9.1 Use NEMA Temp for RTD Value: When this

setpoint is enabled, the TX will use the NEMA
design insulation class to limit the maximum
allowed range of the alarm and trip level. The
maximum allowed temperature range is 240° C or
(464°F).

SP9.2 # Of RTD’S Used for Stator: Up to six RTDs can

be assigned to monitor the stator of the motor.

SP9.3 RTD Voting: When this is enabled, the TX will

not post a trip until 2 RTD’s have exceeded the
trip level. This prevents nuisance RTD tripping.

SP9.4 All 12 RTDs are configured in the following

manner. The first column is the RTD type, the
second column is the RTD description, the third
column is the alarm level, and the fourth column
is the trip level.
The first six RTDs have been pre-programmed
with a description name for the STATOR, with two
RTDs per phase. RTDs #1 & #2 have been
named STATOR PHASE A1 and A2 respectively.
RTDs #3&4 are named STATOR PHASE B1 and
B2, RTDs #5&6 are named STATOR PHASE C1
and C2. If other description names are required,
press the right arrow button from the RTD Type
screen to go the RTD description screen. If no
alarm or trip level is required these setpoints can
be turned off.

screens. Level one setpoints do not require a password
because the data contained in level one is basic
nameplate data and starter control. Level two setpoint
screens require a three-digit password to configure the
protection schemes. Level three setpoint screens require
a four-digit password to access the full range of protection
and starter schemes.

SP10.1 Set Level 2 Password: This level uses a 3-digit

• Thermal Register Alarm: Sets a level in the
thermal register to generate an alarm when the
Thermal Register Capacity Used has exceeded
this level.

• Thermal Alarm Delay: The amount of time
that the Thermal Register Used must exceed
the setpoint before an alarm condition will occur.

SP12.3 Thermal Register Setup Information: This

setpoint group will configure the thermal register
and indicate to the TX which inputs to use when
thermal modeling.

• Cold Stall Time: Enter the time from the motor
manufacturer’s specification sheet or use the
time defined by the OL Class. This setpoint is
used to define the thermal capacity of the motor.

• Hot Stall Time: Enter the amount of time
specified by the motor manufacturer or use half
of the time defined by the OL Class.

• Stopped Cool Down Time: The time the
motor requires to cool down after it has stopped.
Use only the data provided by the motor
manufacturer. This setpoint is used to configure
the cooling rate of the thermal register.

• Running Cool Down Time: The amount of
time the motor requires for cooling down while
running. Use only the data provided by the motor
manufacturer.

• Relay Measured Cool Rates: When the RTD
option is supplied, the TX can be configured to
use the measured cool rates from the RTDs
instead of the programmed settings. This
setpoint should only be enabled when the RTD
option is present.

• Thermal Register Minimum: Sets the value in
the thermal register which represents a motor
running at the nameplate current (with no
overheating or negative sequence currents
present).

• Motor Design Ambient Temperature: Use

WARNING

7.2 SCR Testing Procedure

Failure to remove both line and control power
before starting this procedure may cause
personal injury or death.

Remove both line power and control power from the unit and lock out.
Disconnect any two motor load leads and any two line leads. Disconnect
the SCR connections to main control board J5, J6 and J7. Refer the
Chapter 6 for the main control board layout. Note the type of color coding
of the wires connected to J5, J6 and J7. Toshiba uses two possible
configurations. Both configurations have 4 wires going to each plug. The
first configuration consists of 4 wires color coded black, yellow, grey and
white. The second configuration consists of 4 wires color coded red, white,
red, white.

The testing procedure for SCRs is comprised of two separate tests. The
first one tests the anode to cathode integrity of the SCR by performing the
following ohm checks:

The second tests the gate to cathode integrity of the SCR. The chart below
indicates good versus bad readings.

Note: If any of the above readings are out of specifications, replace
the faulty SCR.

Note: The best way to test an SCR is with an SCR Tester and look for
leakage current less than the manufacturer specified values.

TOSHIBA - 70

TX Series 48 - 1250A

WARNING

7.3 Replacing SCR Devices

Two types of SCRs are used in the TX Series depending on the horsepower/
amperage rating of the unit. Isolated SCRs are used in smaller units and
“hockey puck” type SCRs are used in larger units. (Refer to Chapter 9 for
the main control board layout.)

7.3.1 Changing an Isolated SCR

• Remove both line and control power from unit, tag and lock out.
Failure to remove both line and control power

before starting this procedure may cause personal
injury or death.

• Label the location of wires connected to the SCR.

• Remove the mounting screws, lugs and associated wiring from the

existing SCR.

• Make sure the surface to which the power module mounts is clean

and free from dirt, nicks and scratches.

• Apply thermal grease uniformly along the mounting surface of the

SCR. Spread the grease thinly (3 mil thick) to completely cover
the base of the power module and minimize air pockets. The
grease must be free of contamination.

• Replace the screws and tighten down firmly. All mounting screws

should be 44 lb/in. Units with a maximum amperage rating of up to

48A, should use 26 lbs/in busbar and power lugs. Units with a
maximum amperage of 78A - 120A should use 44 lbs/in busbar
and power lugs.

• Reconnect all busbars, lugs and wires. Check to make sure the
gate and cathode are wired correctly . Use the following chart to
verify the wiring of J5, J6 and J7:

• After verifying that all wiring is correctly connected, test the SCR.

TOSHIBA- 71

TX Series 48 - 1250A

WARNING

7.3.2 Changing a Hockey Puck T ype SCR

• Remove both line and control power from unit, tag and lock out.

Failure to remove both line and control power
before starting this procedure may cause personal
injury or death.

• Toshiba uses two types of clamps with gauges for reading the
amount of force on the device. The first type of force gauge uses a
spin washer. When the proper force is applied, the washer will be
free to spin. The second type of gauge uses a step indicator on the
end of the lever. Before proceeding, note the type of clamp used
and, if the clamp has a step indicator, document the position of the
indicator before removing the clamp to facilitate proper mounting of
the new SCR device.

• Label the location of the wires connected to the SCR.

• Remove any lugs, snubbers, printed circuit boards (refer to section
X) and associated wiring that may get in the way of reaching the
faulty SCR. Document the location and wiring of all parts before
removing them to facilitate the reinstallation of the devices later .

• Document the position of the indicator on the SCR clamp. Then
remove the top clamp holding the SCR stack together. Remove the
top heatsink. Use extreme caution when handling the heat sink so it
does not become dented or damaged.

• Remove the faulty SCR device, noting the direction in which the
SCR is oriented. The new SCR puck must be inserted in the same
direction.

• Make sure the SCR mounting surface, tools, and hands are clean
and free from dirt, nicks, and scratches. Do not sand or scrape SCR
mounting surface. If necessary, super fine Scotch Brite p ads can be
used to clean the heatsink before installing the new SCR.

• Apply a thin (3 mil thick) layer of thermal grease uniformly along
both sides of the SCR. Spread the grease to cover the entire surface

of both sides of the SCR in a manner that minimizes air pockets.

The grease must be free of contamination.

• Locate the centering pin in the bottom and top of the heatsink and
center it in the SCR hole (making sure that the SCR is pointed in the

same direction as the SCR that was removed in step 6). Locate the

centering pin in the top heatsink and center it in the SCR hole.

Caution: If center pin is not placed correctly it will damage
the SCR and the heat sink. Hand tighten the clamps evenly so

that the same number of threads appear at both ends of the U­clamp. Tighten the clamp 1/4 turn at a time alternating sides of the
U-clamp until the correct force is reached. Check the gauge or spin
washer every time the clamp nuts are tightened 1/4 turn to ensure
that the SCR is not over torqued. The gauge reading should be similar

to the initial reading taken in step 2. If the clamp uses the spin

washer gauge, verify that the washer spins freely after clamping.

TOSHIBA - 72

TX Series 48 - 1250A

Once proper force is reached make sure that the SCR pucks are
securely held between the heatsinks and aligned evenly .

• Replace any lugs, MOVs, snubbers, power straps, printed circuit
boards and associated wiring that was removed in step 4. Use the
following chart to verify wiring of J5, J6 and J7:

• After verifying that all wiring is correctly connected, test the SCR
and then test the unit.

7.4 Replacing the Main Control Board

The printed circuit board is not intended to be field repaired. If the
board is faulty , the entire board should be replaced using the
following procedure:

(See Chapter 6 for the main control board layout.)

• Remove three phase power and control power from the unit and
lock out.

• Remove plugs and tag plugs with connector numbers.

• Remove control wires from terminals and tag wires with terminal
numbers.

• Note the settings of all jumpers.

• Remove the mounting screws.

• Remove the old printed circuit board.

• Mount the new printed circuit board.

• Install the mounting screws.

• Set the jumpers to the same position as on the old board.

• Install the control wires onto correct terminals per tag sequence.

• Install the plugs.

• Apply power to the unit and program all parameters to values in
old board.

• Test
