2.2.4 Solid State Motor Overload

The MX

control has an advanced I2t electronic motor overload (OL) protection function. For optimal motor protection the MX3control has forty standard NEMA style overload curves available for use. Separate overloads can be programmed, one for acceleration and another for normal running operation. The overloads can be individual, the same or completely disabled if necessary. The MX overload function also implements a NEMA based current imbalance overload compensation, RTD Biasing, user adjustable hot and cold motor compensation and user adjustable exponential motor cooling.

Figure 2: Commonly Used Overload Curves

motor

The motor overload will NOT trip when the current is less than motor Full Load Amps (FLA) * Service Factor (SF).

The motor overload "pick up" point current is at motor Full Load Amps (FLA) * Service Factor (SF).

The motor overload trip time will be reduced when there is a current imbalance present.

z NOTE: Refer to Theory of Operation, Chapter 7 in section 7.1 for more motor overload details and a larger graph.

Refer to http://www.benshaw.com/olcurves.html for an automated overload calculator.

Before You Start

3.1 Before You Start

3.1.1 Installation Precautions

Inspection

Before storing or installing the RediStart MX

Remove the starter from its package and inspect exterior for shipping damage. If damage is apparent, notify the shipping agent and

•

your sales representative. Open the enclosure and inspect the starter for any apparent damage or foreign objects. Ensure that all of the mounting hardware and

•

terminal connection hardware is properly seated, securely fastened, and undamaged. Ensure all connections and wires are secured.

•

Read the technical data label affixed to the starter and ensure that the correct horsepower and input voltage for the application has

•

been purchased.

The numbering system for a chassis is shown below.

General Information

Installation of some models may require halting production during installation. If applicable, ensure that the starter is installed when production can be halted long enough to accommodate the installation. Before installing the starter, ensure:

The wiring diagram (supplied separately with the starter) is correct for the required application.

•

The starter is the correct current rating and voltage rating for the motor being started.

•

All of the installation safety precautions are followed.

•

The correct power source is available.

•

The starter control method has been selected.

•

The connection cables have been obtained (lugs) and associated mounting hardware.

•

The necessary installation tools and supplies are procured.

•

The installation site meets all environmental specifications for the starter NEMA/CEMA rating.

•

The motor being started has been installed and is ready to be started.

•

Any power factor correction capacitors (PFCC) are installed on the power source side of the starter and not on the motor side.

•

Failure to remove power factor correction or surge capacitors from the load side of the starter will result in serious damage to the starter that will not be covered by the starter warranty. The capacitors must be connected to the line side of the starter. The up-to-speed (UTS) contact can be used to energize the capacitors after the motor has reached full speed.

Series Starter, thoroughly inspect the device for possible shipping damage. Upon receipt:

3.1.2 Safety Precautions

To ensure the safety of the individuals installing the starter, and the safe operation of the starter, observe the following guidelines:

•

Ensure that the installation site meets all of the required environmental conditions (Refer to Site Preparation, page 29).

•

LOCK OUT ALL SOURCES OF POWER.

•

Install circuit disconnecting devices (i.e., circuit breaker, fused disconnect or non-fused disconnect) if they were not previously installed by the factory as part of the package.

•

Install short circuit protection (i.e., circuit breaker or fuses) if not previously installed by the factory as part of the package.

•

Consult Power Ratings for the fault rating on pages 19-21.

•

Follow all NEC (National Electrical Code) and/or C.S.A. (Canadian Standards Association) standards or Local Codes as applicable.

•

Remove any foreign objects from the interior of the enclosure, especially wire strands that may be left over from installation wiring.

•

Ensure that a qualified electrician installs wiring.

•

Ensure that the individuals installing the starter are wearing ALL protective eyewear and clothing.

•

Ensure the starter is protected from debris, metal shavings and any other foreign objects.

The opening of the branch circuit protective device may be an indication that a fault current has been interrupted. To reduce the risk of electrical shock, current carrying parts and other components of the starter should be inspected and replaced if damaged.

3.2 Installation Considerations

3.2.1 Site Preparation

General Information

Before the starter can be installed, the installation site must be prepared. The customer is responsible for:

Providing the correct power source

•

Providing the correct power protection

•

Selecting the control mechanism

•

Obtaining the connection cables, lugs and all other hardware

•

Ensuring the installation site meets all environmental specifications for the enclosure NEMA rating

•

Installing and connecting the motor

•

Power Cables

The power cables for the starter must have the correct NEC/CSA current rating for the unit being installed. Depending upon the model, the power cables can range from a single #14 AWG conductor to four 750 MCM cables. (Consult local and national codes for selecting wire size).

Site Requirements

The installation site must adhere to the applicable starter NEMA/CEMA rating. For optimal performance, the installation site must meet the appropriate environmental and altitude requirements.

3.2.2 EMC Installation Guidelines

General In order to help our customers comply with European electromagnetic compatibility standards, Benshaw Inc. has

developed the following guidelines.

3 - INSTALLATION

Installation Considerations

Attention This product has been designed for Class A equipment. Use of the product in domestic environments may cause radio

Enclosure Install the product in a grounded metal enclosure.

Grounding Connect a grounding conductor to the screw or terminal provided as standard on each controller. Refer to layout/power

Wiring Refer to Wiring Practices on page 31.

Filtering To comply with Conducted Emission Limits (CE requirement), a high voltage (1000V or greater) 0.1 uF capacitor

3.2.3 Use of Power Factor Capacitors

Power factor correction capacitors and surge capacitors CAN NOT be connected between the starter and the motor. These devices can damage the SCRs during ramping. These devices appear like a short circuit to the SCR when it turns on, which causes a di/dt level greater than the SCR can handle. If used, power factor correction capacitors or surge capacitors must be connected ahead of the starter and sequenced into the power circuit after the start is completed. A programmable relay can be configured as an up-to-speed (UTS) relay and then used to pull-in a contactor to connect the capacitors after the motor has reached full speed.

z NOTE: If the motor manufacturer supplies surge capacitors they must be removed before starting.

3.2.4 Use of Electro-Mechanical Brakes

If an electro-mechanical brake is used with the starter, it must be powered from the line side of the starter to ensure full voltage is applied to the brake during a start so it will properly release. A programmable relay can be configured as a run relay and then used to pull-in a contactor to power the brake whenever the starter is providing power to the motor.

3.2.5 Reversing Contactor

If the application requires a reversing contactor, it should be connected on the output side (load) of the soft starter. The contactor must be closed before starting the soft starter. The soft starter must be off before switching the direction of the reversing contactor. The reversing contactor must never be switched while the soft starter is operating.

Mounting Considerations

3.3 Mounting Considerations

3.3.1 Bypassed Starters

Provisions should be made to ensure that the average temperature inside the enclosure never rises above 50°C. If the temperature inside the enclosure is too high, the starter can be damaged or the operational life can be reduced.

3.3.2 Non-Bypassed Starters

Provisions should be made to ensure that the temperature inside the enclosure never rises above 50°C. If the temperature inside the enclosure is too high, the starter can be damaged or the operational life can be reduced. As a general rule of thumb, the following ventilation guidelines can be followed.

Current Range Bottom of Enclosure Top of Enclosure

< 200 amps Fans or grills depending on enclosure size

200 to 300 amps 2 x 4” grills (12 sq. in.) 2 x 4” grills (12 sq.in.)

601 to 700 amps 2 x 6” fan (470 cfm) 2 x 6” grills (28 sq.in.)

> 700 amps Consult factory Consult Factory

Table 13: Ventilation Requirements

The starter produces 4 watts of heat per amp of current and 26 square inches of enclosure surface is required per watt of heat generation. Contact Benshaw and ask for the enclosure sizing technical note for more information concerning starters in sealed enclosures. Benshaw supplies starters under 124 amps non-bypassed, with the heat sink protruding from the back of the enclosure. This allows a small enclosure size while still maintaining the cooling capability of the starter.

3.4 Wiring Considerations

3.4.1 Wiring Practices

When making power and control signal connections, the following should be observed:

Never connect input AC power to the motor output terminals T1/U, T2/V, or T3/W.

•

Power wiring to the motor must have the maximum possible separation from all other wiring. Do not run control wiring in the same

•

conduit; this separation reduces the possibility of coupling electrical noise between circuits. Minimum spacing between metallic conduits containing different wire groups should be three inches (8cm).

Minimum spacing between different wiring groups in the same tray should be six inches.

•

Wire runs outside an enclosure should be run in metallic conduit or have shielding/armor with equivalent attenuation.

•

Whenever power and control wiring cross it should be at a 90 degrees angle.

•

Different wire groups should be run in separate conduits.

•

With a reversing application, the starter must be installed in front of the reversing contactors.

•

z NOTE: Local electrical codes must be adhered to for all wiring practices.

3.4.2 Considerations for Control and Power Wiring

Control wiring refers to wires connected to the control terminal strip that normally carry 24V to 115V and Power wiring refers to wires connected to the line and load terminals that normally carries 200VAC - 600VAC respectively. Select power wiring as follows:

Use only UL or CSA recognized wire.

•

Wire voltage rating must be a minimum of 300V for 230VAC systems and 600V (Class 1 wire) for 460VAC and 600VAC systems.

•

Grounding must be in accordance with NEC, CEC or local codes. If multiple starters are installed near each other, each must be

•

connected to ground. Take care to not form a ground loop. The grounds should be connected in a STAR configuration. Wire must be made of copper and rated 60/75°C for units 124 Amps and below. Larger amp units may use copper or aluminum wire.

•

Refer to NEC table 310-16 or local codes for proper wire selection.

Signal wiring refers to the wires connected to the control terminal strip that are low voltage signals, below 15V.

• Shielded wire is recommended to prevent electrical noise interference from causing improper operation or nuisance tripping.

•

Signal wire rating should carry as high of a voltage rating as possible, normally at least 300V.

•

Routing of signal wire is important to keep as far away from control and power wiring as possible.

3.4.4 Meggering a Motor

If the motor needs to be meggered, remove the motor leads from the starter before conducting the test. Failure to comply may damage the SCRs and WILL damage the control board, which WILL NOT be replaced under warranty.

3.4.5 High Pot Testing

If the starter needs to be high pot tested, perform a DC high pot test. The maximum high point voltage must not exceed 2.0 times rated RMS voltage + 1000VAC (High pot to 75% of Factory). Failure to comply WILL damage the control board, which WILL NOT be replaced under warranty. An example to find the high point voltage is (2.0 * rated RMS voltage + 1000) * 0.75.

3.6 Power Wiring

3.6.1 Recommended Incoming Line Protection

Fuses or Circuit Breaker, refer to pages 19 - 21.

Input Line Requirements

The input line source needs to be an adequate source to start the motor, generally 2 times the rating of the motor FLA. (This may not apply in some cases such as being connected to a generator).

3 - INSTALLATION

Power Wiring

3.6.2

3.6.3 Power Wire Connections

3.6.4 Motor Lead Length

Recommended Wire Gauges

The wire gauge selection is based on the FLA of the motor. Refer to NEC table 310-16 or CEC Part 1, Table 2 or local code requirements for selecting the correct wire sizing. Ensure appropriate wire derating for temperature is applied. If more than three current carrying conductors are in one conduit, ensure NEC table 310.15(B)(2) or CEC Part 1 Table 5C is adhered to. In some areas local codes may take precedence over the NEC. Refer to your local requirements.

Attach the motor cables:

Use the T1, T2 and T3 terminals. Use lugs/crimps or terminals. (Lugs and Crimps are to be provided by the user)

•

Attach the power source cables:

Use the L1, L2 and L3 terminals. Use lugs/crimps or terminals (Lugs and Crimps are to be provided by the user).

•

The standard starter can operate a motor with a maximum of 2000 feet of properly sized cable between the “T” leads of the starter and that of the motor. For wire runs greater than 2000 feet contact Benshaw Inc. for application assistance. If shielded cable is used, consult factory for recommended length.

Current Transformers

3.7 Current Transformers

3.7.1 CT Mounting

For starters larger than 124 amps, the CTs are shipped loose from the power stack and need to be mounted on the power wiring. Thread the motor or incoming lead through the CT with the polarity mark towards the line side. (The polarity marks may be a white or yellow dot, an “X” on the side of the CT, or the white wire.) Each phase has its own CT. The CT must then be attached to the power wiring, at least three inches from the power wire lugs, using two tie-wraps.

Table 17: Tightening Torque for Inside Hex Screws

Socket size across flats Tightening torque

3.7.2 CT Polarity

The CT has a polarity that must be correct for the starter to correctly measure Watts, kW Hours, Power Factor, and for the Power and TruTorque motor control functions to operate properly.

Each CT has a dot on one side of the flat surfaces. This dot, normally white in color, must be facing in the direction of the line.

CT1 must be on Line L1, CT2 must be on Line L2, CT3 must be on Line L3.

3.7.3 Zero Sequence Ground Fault Current Transformer

The Zero Sequence Ground Fault CT can be installed over the three phase conductors for sensitive ground current detection or for use with high resistance grounded systems.

Figure 13: BICT 2000/1-6 Mechanical Dimensions

3 - INSTALLATION

The correct installation of the current transformer on the motor leads is important. The shield ground wire should also be passed through the CT window if the motor conductors use shielded cable. Otherwise, capacitive coupling of the phase current into the cable shield may be measured as ground fault current. See figure below for proper installation.

3.13.1 Location

The mounting location for the Remote RTD Module should be chosen to give easy access to the RTD wiring, control terminals and indicator LEDs as well as providing a location to mount the power supply. The Remote RTD Module is specifically designed to be mounted close to the equipment it is monitoring. This eliminates long RTD wire lengths which save time and money on installation and wiring. The Benshaw Remote RTD Module is designed to mount on industry standard 35mm wide by 7.5mm deep DIN rail.

Figure 29: Remote RTD Module Mechanical Layout

3.13.2 Modbus Address

Set the rotary switch on the top of the Remote RTD Module to the desired Modbus address. Up to 2 modules can be connected to the

starter. The address set by the rotary switch must match the setting in RTD 01 or RTD 02. For example, setting both the rotary switch and RTD 01 to 16 would make the connected module be module #1. The connected RTDs would then represent #1 to #8 in the RTD programming.

3.13.3 Power Connections

The 24VDC power source is connected to the following terminals.

•

24VDC-: Negative connection to 24VDC power supply

•

24VDC+: Positive connection to 24VDC power supply

•

"g": Chassis ground connection

3.13.4 RS-485 Communication

5 Parameter Groups

5 - PARAMETER GROUPS

Introduction

5.1 Introduction

The MX3incorporates a number of parameters that allow you to configure the starter to meet the special requirements of your particular application.

The parameters are divided into groups of related functionality, and within the groups the parameters are identified by a short, descriptive name. They are numbered by the group name followed by an index within the group.

This chapter lists all of the parameters and their possible values.

5.2 LCD Display Parameters

The parameters are subdivided into six groups. The groups are QST (Quick Start), CFN (Control Functions), PFN (Protection Functions), I/O (Input/Output Functions), RTD (Resistance Temperature Device), FUN (Function), FL1(Fault Log) and E01 (Event Recorder).

The Quick Start Group provides a collection of the parameters that are most commonly changed when commissioning a starter. Many of the parameters in the Quick Start group are duplicates of the same parameters in other groups.

The following shows the menu structure for the LCD display as well as the text that is displayed for the parameters on the display.

If the LCD is not connected, most parameters shown on the LED display will turn on when LCD is unplugged.

QST: Motor FLA 01 10 Amp

Range 1 – 6400 Amps RMS (Default 10A)

Description The Motor FLA parameter configures the motor full load amps, and is obtained from the nameplate on the

attached motor.

If multiple motors are connected, the FLA of each motor must be added together for this value.

z NOTE: Incorrectly setting this parameter prevents proper operation of the motor overload protection, motor over current protection, motor undercurrent protection, ground fault protection and acceleration control.

QST: Motor SF 02 1.15

Range 1.00 – 1.99 (Default 1.15)

6 - PARAMETER DESCRIPTION

Description The Motor Service Factor parameter should be set to the service factor of the motor. The service factor is

See Also Theory of Operation section 7.2, Motor Service Factor on page 147.

used for the overload calculations. If the service factor of the motor is not known, then the service factor should be set to 1.00.

z NOTE: The NEC (National Electrical Code) does not allow the service factor to be set above 1.40. Check with other local electrical codes for their requirements.

The National Electrical Code, article 430 Part C, allows for different overload multiplier factors depending on the motor and operating conditions. NEC section 430-32 outlines the allowable service factor for different motors.

Motor Running Overload Class QST 03

LCD Display:

QST: Running OL 03 10

Range Off,1–40(Default 10)

Description The Motor Running Overload Class parameter sets the class of the electronic overload for starting and

running if the Independent Starting / Running Overload parameter is set to "Off". If separate starting versus running overload classes are desired, set the Independent S/R OL (PFN28) parameter to "On".

The starter stores the thermal overload value as a percentage value between 0 and 100%, with 0% representing a “cold” overload and 100% representing a tripped overload.

When the parameter is set to "Off", the electronic overload is disabled in all states, starting and running. A separate motor overload protection device must be supplied.

z NOTE: Care must be taken not to damage the motor when turning the running overload class off or setting a high value.

z NOTE: Consult motor manufacturer data to determine the correct motor overload settings.

Initial Current 1 QST 06

LCD Display

QST: Init Cur 1 06 100 %

Range 50–600%ofFLA(Default 100%)

Description The Initial Current 1 parameter is set as a percentage of the Motor FLA (QST01) parameter setting. The

Initial Current 1 parameter sets the current that is initially supplied to the motor when a start is commanded. The initial current should be set to the level that allows the motor to begin rotating within a couple of seconds of receiving a start command.

To adjust the initial current setting, give the starter a run command. Observe the motor to see how long it takes before it begins rotating and then stop the unit. For every second that the motor doesn’t rotate, increase the initial current by 20%. Typical loads require an initial current in the range of 50% to 175%.

If the motor does not rotate within a few seconds after a start command, the initial current should be increased. If the motor accelerates too quickly after a start command, the initial current should be decreased.

The Initial Current 1 parameter must be set to a value that is lower than the Maximum Current 1 parameter setting.

Maximum Current 1 QST 07

LCD Display

QST: Max Cur 1 07 600 %

Range 100 – 800 % of FLA (Default 600%)

Description The Maximum Current 1 parameter is set as a percentage of the Motor FLA (QST01) parameter setting. This

parameter performs two functions. It sets the current level for the end of the ramp profile, as well as the maximum current that is allowed to reach the motor after the ramp is completed.

If the ramp time expires before the motor has reached full speed, the starter holds the current at the maximum current level until either the UTS timer expires; the motor reaches full speed, or the overload trips.

Typically, the maximum current is set to 600% unless the power system or load dictates the setting of a lower maximum current.

Ramp Time 1 QST 08

LCD Display

QST: Ramp Time 1 08 15 sec

Range 0 – 300 seconds (Default 15)

Description The Ramp Time 1 parameter is the time it takes for the starter to allow the current, voltage, torque or power

(depending on the start mode) to go from its initial to the maximum value. To make the motor accelerate faster, decrease the ramp time. To make the motor accelerate slower, increase the ramp time.

A typical ramp time setting is from 15 to 30 seconds.

If the ramp time expires before the motor reaches full speed, the starter maintains the maximum current level until either the motor reaches full speed, the UTS timer expires, or the motor thermal overload trips.

z NOTE: Setting the ramp time to a specific value does not necessarily mean that the motor will take this time to accelerate to full speed. The motor and load may achieve full speed before the ramp time expires if the application does not require the set ramp time and maximum current to reach full speed. Alternatively, the motor and load may take longer than the set ramp time to achieve full speed.

6 - PARAMETER DESCRIPTION

Up To Speed Time QST 09

LCD Display

QST: UTS Time 09 20 sec

Range 1 – 300 seconds (Default 20)

Description The Up To Speed Time parameter sets the maximum acceleration time to full speed that the motor can take. A

stalled motor condition is detected if the motor does not get up-to-speed before the up-to-speed timer expires. The motor is considered up-to-speed once the current stabilizes below 175 percent of the FLA value and the ramp time expires.

z NOTE: During normal acceleration ramps, the up-to-speed timer has to be greater than the sum of the highest ramp time in use and the kick time. The up-to-speed timer does not automatically change to be greater than the ramp time. If a ramp time greater than the up-to-speed timer is set, the starter will declare an up-to-speed fault every time a start is attempted.

z NOTE: When the Start Mode parameter (CFN01) is set to "Voltage Ramp", the UTS timer acts as an acceleration kick. When the UTS timer expires, full voltage is applied to the motor. This feature can be used to reduce motor oscillations if they occur near the end of an open loop voltage ramp start.

z NOTE: When the starter type parameter (FUN07) is set to "Wye-Delta", the UTS timer is used as the transition timer. When the UTS timer expires, the transition from Wye starting mode to Delta running mode takes place if it has not already occurred.

Fault Code 01 - Up to Speed Fault is declared when a stalled motor condition is detected.

The closed loop power control acceleration ramp is ideal for starting applications using a generator or other limited capacity source.

In addition to the basic motor and starter setup variables, the following needs to be done to use the tachometer feedback control ramp:

1. Connect a tachometer with appropriate DC output voltage and correct polarity to the MX power card input (TB5-2(+input), TB5-3(-input)).

2. The start mode (CFN01) is to be selected as Tach Ramp.

3. Program Tachometer Full Speed Voltage (FUN13).

4. Program Tachometer Loss Time (FUN14).

5. Program Tachometer Loss Action (FUN15).

6. Set the Initial Current Level (CFN03) to the desired current limit.

CFN: Init V/T/P 08 25%

Range 1 – 100 % of Voltage/Torque/Power (Default 25%)

Description Start Mode (CFN01) set to Open Loop Voltage Acceleration:

This parameter sets the starting point for the voltage acceleration ramp profile. A typical value is 25%. If the motor starts too quickly or the initial current is too high, reduce this parameter. If the motor does not start rotating within a few seconds after a start is commanded, increase this parameter.

Start Mode (CFN01) set to Current Control Acceleration: Not used when the Start Mode parameter is set to Current control acceleration. Refer to the Initial Current 1 parameter (CFN03) to set the initial current level.

Start Mode (CFN01) set to TruTorque Control Acceleration: This parameter sets the initial torque level that the motor produces at the beginning of the starting ramp profile. A typical value is 10% to 20%. If the motor starts too quickly or the initial torque level is too high, reduce this parameter. If the motor does not start rotating within a few seconds after a start is commanded, increase this parameter. If the value is set too low a “No Current at Run” fault may occur during acceleration.

z NOTE: It is important that the FUN06 - Rated Power Factor parameter is set properly so that the actual initial torque level is the value desired.

Start Mode (CFN01) set to (kW) Power Control Acceleration: This parameter sets the initial motor power (KW) level that will be achieved at the beginning of the starting ramp profile. A typical value is 10% to 30%. If the motor starts too quickly or the initial power level is too high, reduce this parameter. If the motor does not start rotating within a few seconds after a start is commanded, increase this parameter. If the value is set too low a “No Current at Run” fault may occur during acceleration.

Description Start Mode (CFN01) set to Open Loop Voltage Acceleration:

See Also Start Mode (CFN01) on page 78.

Not used when the Start Mode parameter is set to open-loop voltage acceleration. When in open loop voltage acceleration mode, the final voltage ramp value is always 100% or full voltage.

Start Mode (CFN01) set to Current Control Acceleration: Not used when the Start Mode parameter is set to current control acceleration mode. Refer to the Maximum Current 1 parameter (CFN04) to set the maximum current level.

Start Mode (CFN01) set to TruTorque Control Acceleration: This parameter sets the final or maximum torque level that the motor produces at the end of the acceleration ramp time. For a loaded motor, the maximum torque value initially should be set to 100% or greater. If the maximum torque value is set too low, the motor may not produce enough torque to reach full speed and may stall. On lightly loaded motors, this parameter may be reduced below 100% to produce smoother starts.

z NOTE: It is important that the FUN06 - Rated Power Factor parameter is set properly so that the desired maximum torque level is achieved.

Start Mode (CFN01) set to Power Control Acceleration: This parameter sets the final or maximum power (KW) consumption level that will be achieved at the end of the ramp time. For a loaded motor, the maximum power value initially should be set to 100% or greater. If the maximum power level is set too low, the motor may not produce enough torque to reach full speed and may stall. On lightly loaded motors, this parameter may be reduced below 100% to provide for smoother starts.

Acceleration Ramp Profile CFN 10

CFN: Accel Prof 10 Linear

Range Linear (Default)

Description Linear – The linear profile linearly increases the control reference (voltage, current, torque, power, speed)

Square S-Curve

from the initial acceleration ramp value to the final acceleration ramp value. The linear profile is the default profile and is recommended for most acceleration and deceleration situations.

Linear

Squared – The squared profile increases the control reference (voltage, current, torque, power, speed) in a

squared manner. A squared acceleration profile can be useful when using TruTorque control on a load with a squared torque characteristic (such as pumps, and fans). A squared torque profile can provide a more linear speed profile during acceleration and deceleration.

Squared

S–Curve – The S-curve profile slowly increases the control reference’s rate of change at the beginning of the

ramp profile and an slowly decreases the rate of change of the reference at the end of the ramp profile. This profile can be useful when using closed loop tach control to smooth the starting and ending of the acceleration profile. It can also be useful with other types of control methods that require extra smooth starts.

Kick Level 1 CFN 11

LCD Display

CFN: Kick Lvl 1 11 Off

Range Off, 100 – 800% of FLA (Default Off)

Description The Kick Level 1 parameter sets the current level that precedes any ramp when a start is first commanded.

The kick current is only useful on motor loads that are hard to get rotating but then are much easier to move once they are rotating. An example of a load that is hard to get rotating is a ball mill. The ball mill requires a high torque to get it to rotate the first quarter turn (90°). Once the ball mill is past 90°of rotation, the material inside begins tumbling and it is easier to turn.

The kick level is usually set to a low value and then the kick time is adjusted to get the motor rotating. If the kick time is set to more than 2.0 seconds without the motor rotating, increase the kick current by 100% and re-adjust the kick time.

Kick Time 1 CFN 12

LCD Display

CFN: Kick Time 1 12 1.0 sec

Range 0.1 – 10.0 seconds (Default 1.0)

Description The Kick Time 1 parameter sets the length of time that the kick current level (CFN11) is applied to the motor.

The kick time adjustment should begin at 0.5 seconds and be adjusted by 0.1 or 0.2 second intervals until the motor begins rotating. If the kick time is adjusted above 2.0 seconds without the motor rotating, start over with a higher kick current setting.

6 - PARAMETER DESCRIPTION

Description Coast:

See Also Decel Begin Level parameter (CFN16) on page 86.

A coast to stop should be used when no special stopping requirements are necessary; Example: crushers, balls mills, centrifuges, belts, conveyor. The bypass contactor is opened before the SCRs stop gating to reduce wear on the contactor contacts.

Voltage Decel:

In this mode, the starter linearly phases-back the SCRs based on the parameters Decel Begin Level, Decel End Level, and Decel Time.

TruTorque Decel:

In this mode, the starter linearly reduces the motor torque based on the Decel End Level and Decel Time.

DC Brake:

In this mode the starter provides D.C. injection for frictionless braking of a three phase motor.

z NOTE: The MX desirable for the motor to be stopped in a controlled manner (Voltage Decel, TT Decel or D.C. Braking) instead of being allowed to coast to a stop when this occurs. This may be achieved by setting the Controlled Fault Stop (PFN 25) parameter to On. Be aware however that not all fault conditions allow for a controlled fault stop.

Decel Begin Level CFN 16

LCD Display

CFN: Decel Begin 16 40 %

Range 1 – 100% of phase angle firing (Default 40%)

Description Stop Mode (CFN15) set to Voltage Deceleration:

The voltage deceleration profile utilizes an open loop S-curve voltage ramp profile. The Decel Begin Level parameter sets the initial or starting voltage level when transferring from running to deceleration. The deceleration beginning level is not a precise percentage of actual line voltage, but defines a point on the S-curve deceleration profile.

A typical voltage decel begin level setting is between 30% and 40%. If the motor initially surges (oscillates) when a stop is commanded, decrease this parameter value. If there is a sudden drop in motor speed when a stop is commanded, increase this parameter value.

Stop Mode (CFN15) set to TruTorque Deceleration: Not used when the Stop Mode parameter is set to TruTorque Decel. The TruTorque beginning deceleration level is automatically calculated based on the motor load at the time the stop command is given.

z NOTE: It is important that the FUN06 - Rated Power Factor parameter is set properly so that the actual deceleration torque levels are the levels desired.

Decel End Level CFN 17

LCD Display

CFN: Decel End 17 20 %

Range 1 – 99 % of phase angle firing (Default 20%)

Description Stop Mode (CFN15) set to Voltage Deceleration:

The voltage deceleration profile utilizes an open loop S-curve voltage ramp profile. The Decel End Level parameter sets the ending voltage level for the voltage deceleration ramp profile. The deceleration ending level is not a precise percentage of actual line voltage, but defines an ending point on the S-curve deceleration profile.

A typical voltage decel end level setting is between 10% and 20%. If the motor stops rotating before the deceleration time has expired, increase this parameter value. If the motor is still rotating when the deceleration time has expired, decrease this parameter value. If the value is set too low a “No Current at Run” fault may occur during deceleration.

z NOTE: The deceleration end level cannot be set greater than the decel begin level.

Stop Mode (CFN15) set to TruTorque Deceleration The decel end level parameter sets the ending torque level for the TruTorque deceleration ramp profile.

A typical TruTorque decel end level setting is between 10% and 20%. If the motor stops rotating before the deceleration time has expired, increase this parameter value. If the motor is still rotating when the deceleration time has expired, decrease this parameter value.

of the deceleration ramp profile. When in voltage decel mode, this time sets the time to ramp from the initial decel level to the final decel level.

z NOTE: If the motor is not up to speed when a stop is commanded, the voltage decel profile begins at the lower of either the decel begin level setting or at the motor voltage level when the stop is commanded. Although the profile may be adjusted, the deceleration time remains the same.

When in the TruTorque deceleration mode, the decel time sets the time between when a stop is commanded and when the decel end torque level is applied.

If the motor stops rotating before the decel time expires, decrease the decel time parameter. If the motor is still rotating when the decel time expires, increase the decel time parameter.

A typical decel time is 20 to 40 seconds.

z NOTE: Depending on the motor load and the decel parameter settings, the motor may or may not be fully stopped at the end of the deceleration time.
