2.2.4 Solid State Motor Overload

The MX2 control has an advanced I2t electronic motor overload (OL) protection function. For optimal motor protection the MX2 control 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 MX2 motor overload function also implements a NEMA based current imbalance overload compensation, user adjustable hot and cold motor compensation and user adjustable exponential motor cooling.

Figure 2: Commonly Used Overload Curves

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, section 7.1 on page 132 for more motor overload details and a larger graph.

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

2.3 Starter Power Ratings

Each RB2 model starter is rated for three different starting duties. For example, a starter can operate a:

300HP motor for a standard duty start (350% for 30 seconds)

200HP for a heavy duty start (500% for 30 seconds)

150HP motor for a severe duty start (600% for 30 seconds)

450HP motor when connected to the inside delta of a motor for a standard duty start (350% for 30 seconds)

Before You Start

3.1 Before You Start

3.1.1 Inspection

Before storing or installing the RediStart MX2 Series Starter, thoroughly inspect the device for possible shipping damage. Upon receipt:

• 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.

3.1.2 Installation Precautions

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.

3.1.3 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 18-20.

• 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

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 not 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 12: 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 208VAC - 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.

3 - INSTALLATION

Wiring Considerations

3.4.3 Considerations for Signal Wiring

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

Perform a DC high pot test if it is necessary to verify the insulation of the soft starter. The factory test voltage used is two and a half times the RMS voltage plus 1000VDC. It is recommended to test equipment that has been in service to 75% of the factory test voltage. The SCR gate leads must be removed from the control board to perform the high pot test. Remove the twisted red and white wire pairs labeled from 1 to 6 that connect on the right side of the control card. Failure to comply with the test voltage or removing the gate wiring may damage the control board which will not be replaced under warranty..

3.6 Power Wiring

3.6.1 Recommended Incoming Line Protection

Fuses or Circuit Breaker, refer to pages 18 - 20.

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).

3.6.2 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.

3.6.3 Power Wire Connections

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).

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 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 16: 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.

Introduction

4.1 Introduction

The MX2 provides a comprehensive set of parameters to allow the use of the reduced voltage solid state starter in nearly any industrial application. While the starter can meet the requirements of many applications right out of the box, customization of parameter values to better suit your particular application is easily accomplished with the standard, on-board, 4-digit, 7-segment LED display/keypad.

The MX2 has an optional 2x16 character, back-lit LCD display/keypad that may be mounted remotely from the MX2 control card. The remote LCD keypad has the same keys as the standard display with several additional keys including start and stop keys for operation of the starter from the keypad. When the remote LCD keypad is connected, the local display is disabled.

Standard Keypad and Display

4.2 Standard Keypad and Display

The LED display provides information on starter operation and programming. The 4-digit, 7-segment display shows starter meter outputs and programming data. Special symbols provide further information about the starter operation (see the following section).

Introduction

5.1 Introduction

The MX2 incorporates a number of parameters that allow you to configure the starter to meet the special requirements of your particular application. The parameters are organized two ways, depending on the display being used. When the standard, on-board LED display is used, the parameters are in a single group and numbered P1, P2, P3… etc.

When the remote LCD display is used, the parameters are divided into groups of related functionality, and within the groups the parameters are identified by a short, descriptive name. The parameters are subdivided into six groups. The groups are QST (Quick Start), CFN (Control Functions), PFN (Protection Functions), I/O (Input/Output Functions), FUN (Function) and FL1 (Faults) .

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 parameters in the other groups.

This chapter lists all of the parameters and their possible values. Section 5.3 lists the parameters in the order in which they appear on the LED display. Section 5.4 lists them in the order in which they appear on the LCD display. Section 5.2 is a cross-reference between the two.

LCD Display Parameters

5.4 LCD Display Parameters

The 2x16 display has the same parameters available as the LED display, with the exception of two meter parameters instead of one since two meters may be displayed on the main screen. The parameters are subdivided into five groups. The groups are QST (Quick Start), CFN (Control Functions), I/O (Input/Output Functions), PFN (Protection Functions) and FUN (Function).

The MX2 incorporates 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.

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

6.1 Parameter Descriptions

The detailed parameter descriptions in this chapter are organized in the same order as they appear on the LED display. If the remote LCD display is being used, the table in chapter 5 beginning on page 62 can be used to find the page number of the parameter in this chapter.

Each parameter has a detailed description that is displayed with the following format.

P__ Parameter Name MMM__

LED Display LCD Display

MMM: Parameter

MI Value

Range Parameter Value (Default: Constant)

LED LCD

EEE Keypad

Description The description of the function.

See Also Cross references to related parameters or other chapters.

In the above format, the header box for the parameter contains the P number (as it appears in the menu on the LED display), the parameter name and the parameter group number (as it appears in the menu on the LCD display).

The LCD Display section shows an example of what actually appears on the remote mounted keypad. The LED display shows an example of what actually appears on the built in display. The parameter group (represented above by “MMM”) and the (possibly abbreviated) parameter name are shown on the first line. The parameter group number (represented above by “MI” for “menu index”) and the parameter’s value and units are shown on the second line.

Some parameters appear in two different menus of the LCD display. This is the case for those parameters that are in the Quick Start Group. In this case, both LCD menu groups are listed in the header box and two example LCD displays are shown.

For some parameters, the Range section is enough to describe the parameter. For others, there may be an additional Options section to describe each of the options that a parameter may be set to. The form that the options take may be different for the LED and LCD displays, so this section shows how the options appear on both displays.

The See Also section lists cross-references to other parameters that may be related as well as references to further detail in other chapters.

Range Model Dependent, 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.

P2 Motor Service Factor QST 02

LED Display LCD Display

QST: Motor SF

02 1.15

Range 1.00 – 1.99 (Default 1.15)

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

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.

running. If separate starting versus running overload classes are desired, set the independent S\R O/L (P44 / PFN13) 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. See section 7.1, for the overload trip time versus current curves.

When the parameter is set to "Off", the electronic overload is disabled when up to speed and 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 to a high value.

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

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 (P7 / QST

07) parameter setting.

setting. This parameter performs two functions. It sets the current level for the end of the ramp profile. It also sets 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 or higher maximum current.

(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.

P9 Up To Speed Time QST 09

LED Display LCD Display

QST: UTS Time

09 20 sec

Range 1– 900 Seconds (Default 20)

Description The Up To Speed Time parameter sets the maximum time the motor can take to accelerate to full speed. 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 (P10 / CFN 01) parameter 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 (P74 / FUN 07) parameter 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.

Description The Start Mode parameter allows the selection of the optimal starting ramp profile based on the application.

The closed loop current control acceleration ramp is ideal for starting most general-purpose motor applications. Ex: crushers, ball mills, reciprocating compressors, saws, centrifuges, and most other applications.

The closed loop TruTorque control acceleration ramp is suitable for applications that require a smooth torque output from the motor during starting. Ex: centrifugal pumps, fans. The Tru Torque is also suitable for belt driven applications to eliminate belt sequel that commonly occurs near full speed.

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

CFN: Init V/T/P

08 25 %

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

Description Start Mode (P10/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 (P10/CFN01) set to Current Control Acceleration: Not used when the Start Mode parameter is set to Current control acceleration. Refer to the P6 - Initial Current 1 (CFN03) parameter to set the initial current level.

Start Mode (P10/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 (P75 / FUN06) - Rated Power Factor parameter is set properly so that the actual initial torque level is the value desired.

Start Mode (P10/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 (P10/CFN01) set to Open Loop Voltage Acceleration:

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 (P10/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 (P7 / CFN04) parameter to set the maximum current level.

Start Mode (P10/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 (P75 / FUN06) - Rated Power Factor parameter is set properly so that the desired maximum torque level is achieved.

Start Mode (P10/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.

z NOTE: It is important that the (P75 / FUN06) - Rated Power Factor parameter is set properly so that the actual maximum power level is achieved.

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.

See Also Start Mode (P10 / CFN 01) parameter on page 83.

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.

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 (P13 / CFN 10) 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.

z NOTE: The kick time adds to the total start time and must be accounted for when setting the UTS time.

CoS Coast Coast to stop. (Default) SdcL Volt Decel Open loop voltage deceleration. tdcL TT Decel TruTorque deceleration. dcb DC Brake DC Braking.

Description Coast:

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 MX2 stops the motor when any fault occurs. Depending on the application, it may be 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 Enable (P43 / PFN12) parameter to "On". Be aware, however, that not all fault conditions allow for a controlled fault stop.

CFN: Decel Begin

15 40 %

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

Description Stop Mode (P15/CFN14) 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 (P15/CFN14) 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 (P75 / FUN06) - Rated Power Factor parameter is set properly so that the actual deceleration torque levels are the levels desired.

LED Display LCD Display

CFN: Decel End

16 20 %

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

Description Stop Mode (P15/CFN14) 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 (P15/CFN14) 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.

P18 Decel Time CFN 17

LED Display LCD Display

CFN: Decel Time

17 15 sec

Range 1 – 180 seconds (Default 15)

Description The Decel Time parameter sets the time that the deceleration profile is applied to the motor and sets the slope

of the deceleration ramp profile. When in voltage decel mode, this time sets the time between applying 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.

P19 DC Brake Level CFN 18

LED Display LCD Display

CFN: Brake Level

18 25 %

Range 10 – 100 % of available brake torque (Default 25%)

Description When the Stop Mode (P15 / CFN 14) is set to DC brake, the DC Brake Level parameter sets the level of DC

current applied to the motor during braking. The desired brake level is determined by the combination of the system inertia, system friction, and the desired braking time. If the motor is braking too fast the level should be reduced. If the motor is not braking fast enough the level should be increased. Refer to Nema MG1, Parts 12 and 20 for maximum load inertia. A Thermistor, Thermostat or RTD MUST be installed to protect the motor.

DC Brake Function Programming Steps:

1. The DC Brake function may be enabled by setting the stop mode (P15 / CFN 14) to DC Brake.

2. Once this function is enabled, a relay output configuration (P52,53,54 / I/O 05,06,07) must be used to control the DC brake contactor or 7th SCR gate drive card during braking. It is recommended to use Relay K3 - (P54 / I/O 07).

z NOTE: Standard braking

z NOTE: Heavy duty braking

z NOTE: When DC injection braking is utilized, discretion must be used when setting up the DC Brake

Level. Motor heating during DC braking is similar to motor heating during starting. Even though the Motor OL is active (if not set to "Off") during DC injection braking, excessive motor heating could still result if the load inertia is large or the brake level is set too high. Caution must be used to assure that the motor has the thermal capacity to handle braking the desired load in the desired period of time without excessive heating.

z NOTE: Consult motor manufacturer for high inertia applications.

z NOTE: Not to be used as an emergency stop. When motor braking is required even during a power outage

an Electro mechanical brake must be used.

- For load inertia less than 6 x motor inertia

- For NEMA MG1 parts 12 and 20 maximum load inertia
