Before You Start

3.1 Before You Start

3.1.1 Installation Precautions

Inspection

Before storing or installing the RediStart MVRMX 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.

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

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 19).

•

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.

•

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 21.

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

3.2.3 R-Rated Motor Starter Fuses

R-rated fuses are current-limiting, high interrupting rating fuses intended for the short-circuit protection of medium voltage motors and motor controllers. R-rated fuses are back up fuses that have a minimum interrupting rating, and must be coordinated with overload relays in combination motor starters.

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.

should be connected from each input line to ground at the point where the line enters the cabinet.

3 - INSTALLATION

3.2.6 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.

Figure 4: Separate Power Factor Correction Disconnect

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

Figure 5: Integral Power Factor Correction Disconnect

3.3 Mounting Considerations

3.3.1 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.

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 degree 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 - INSTALLATION

Mounting Considerations

Wiring Considerations

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 2200VAC to 7200VAC respectively. Select power wiring as follows:

Use only UL or CSA recognized wire.

•

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.

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

If the starter needs to be high pot tested, perform a DC high pot test. The maximum high pot voltage must not exceed 2.0 times rated RMS voltage + 2000VAC (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 maximum high pot voltage is (2.0 * rated RMS voltage + 2000) * 0.75.

3.6 Power Wiring

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).

3.6.1 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.

3.6.2 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).

•

3.6.3 Motor Lead Length

The standard starter can operate a motor with a maximum of 600 feet of properly sized cable between the “T” leads of the starter and that of the motor. For wire runs greater than 600 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

If the CTs are shipped loose they need to be mounted on the power wiring. Thread the power wire through the CT and supplied sleeving, ensuring the polarity mark is 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 using two tie-wraps.

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 9: 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 10 below for proper installation.

z NOTE: Power cable must be covered with voltage rated sleeving/tubing extending a minimum of 3" past both sides of the CT. See Figure 8 for sleeve installation.

5 Parameter Groups

5 - PARAMETER GROUPS

Introduction

5.1 Introduction

The MVRMX3incorporates 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.

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 Indep S/R OL (PFN 28) parameter is set to "Off". If separate starting versus running overload classes are desired, set the Indep S/R OL (PFN 28) 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.

6 - PARAMETER DESCRIPTION

Description The Initial Current 1 parameter is set as a percentage of the Motor FLA (QST 01) parameter setting. This

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 (QST 07) parameter setting.

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.

(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.

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 (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 (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.

Voltage Ramp Open Loop Voltage acceleration ramp. Current Ramp Current control acceleration ramp. (Default) TT Ramp TruTorque control acceleration ramp. Power Ramp Power (kW) control acceleration ramp. Tach Ramp Tachometer control acceleration ramp.

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 minimum of torque transients during starting or for consistently loaded applications that require a reduction of torque surges during starting. Ex: centrifugal pumps, fans, and belt driven equipment.

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:

•

Connect a tachometer with appropriate DC output voltage and correct polarity to the MX3power card input (TB5-2(+input), TB5-3(-input)).

Initial Voltage/Torque/Power CFN 08

LCD Display

CFN: Init V/T/P 08 25 %

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

Description Start Mode (CFN 01) 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 (CFN 01) set to Current Control Acceleration: Not used when the Start Mode parameter is set to Current control acceleration. Refer to the Initial Current 1 (QST 06/CFN 03) parameter to set the initial current level.

Start Mode (CFN 01) 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 Rated Power Factor (FUN 06) parameter is set properly so that the actual initial torque level is the value desired.

Start Mode (CFN 01) 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 (CFN 01) set to Open Loop Voltage Acceleration:

See Also Start Mode (CFN 01) on page 63.

Not used when the Start Mode (CFN 01) 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 (CFN 01) set to Current Control Acceleration: Not used when the Start Mode (CFN 01) parameter is set to current control acceleration mode. Refer to the Maximum Current 1 (CFN 04) parameter to set the maximum current level.

Start Mode (CFN 01) 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 Rated Power Factor (FUN 06) parameter is set properly so that the desired maximum torque level is achieved.

Start Mode (CFN 01) 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 Rated Power Factor (FUN 06) parameter is set properly so that the actual maximum power level is achieved.

Acceleration Ramp Profile CFN 10

LCD Display

CFN: Accel Prof 10 Linear

Range Linear, Square, S-Curve (Default: Linear)

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

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

6 - PARAMETER DESCRIPTION

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.

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.

See Also Start Mode on (CFN 01) on page 63.

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 sec)

Description The Kick Time 1 parameter sets the length of time that the kick current level 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.

Decel Begin Level CFN 16

LCD Display

CFN: Decel Begin 16 40 %

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

Description Stop Mode (CFN 15) 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 (CFN 15) 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.

LCD Display

CFN: Decel End 17 20 %

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

Description Stop Mode (CFN 15) 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 (CFN 15) 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.

CFN: Decel Time 18 15 sec

Range 1 – 180 seconds (Default: 15 sec)

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. 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.

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.

6 - PARAMETER DESCRIPTION

If the motor stops rotating before the decel time expires, decrease the Decel Time (CFN 18) parameter. If the motor is still rotating when the decel time expires, increase the Decel Time (CFN 18) 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.

DC Brake Level CFN 20

LCD Display

CFN: Brake Level 20 25 %

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

Description When the Stop Mode (CFN 15) 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 inertias. A PTC Thermistor 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 (CFN 15) parameter to "DC Brake".

2. Once this function is enabled, a relay output configuration (I/O 10 - 15) must be used to control the DC brake contactor or 7th SCR gate drive card during braking. It is recommended to use Relay R3 - (I/O12) because it is a higher rated relay.

z NOTE: Standard duty braking

- For load inertias less than 6 x motor inertia

Heavy duty braking

- For NEMA MG1 parts 12 and 20 maximum load inertias

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.

6 - PARAMETER DESCRIPTION

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

that DC current is applied to the motor. The required brake time is determined by the combination of the system inertia, system friction, and the desired braking level. If the motor is still rotating faster than desired at the end of the brake time increase the brake time if possible. If the motor stops before the desired brake time has expired decrease the brake time to minimize unnecessary motor heating.

when a stop is commanded and the DC braking current is applied to the motor. This delay allows the residual magnetic field and motor counter EMF to decay before applying the DC braking current. If a large surge of current is detected when DC braking is first engaged increase the delay time. If the delay before the braking action begins is too long then decrease the delay time. In general, low horsepower motors can utilize shorter delays while large horsepower motor may require longer delays.

Slow speed operation is commanded by programming one of the digital inputs to either "Slow Speed Forward" or "Slow Speed Reverse". Energizing the Slow Speed Input when the starter is idle will initiate slow speed operation.

z NOTE: When the motor is operating at slow speeds its cooling capacity can be greatly reduced. Therefore, the running time of the motor at a given current level is dependant on the motor’s thermal capacity. Although the Motor OL is active (if not set to "Off") during slow speed operation, it is recommended that the motor temperature be monitored when slow speed is used for long periods of time.

z NOTE: The Slow Speed Time Limit includes the time used for the Slow Speed Kick Time (CFN27) parameter if kick is enabled.

z NOTE: The Slow Speed Time Limit resets when the motor is stopped. Therefore, this timer does not prevent the operator from stopping slow speed operation and re-starting the motor, which can result in the operation time of the motor being exceeded.

z NOTE: When the motor is operating at slow speeds, its cooling capacity can be greatly reduced. Therefore, the running time of the motor at a given current level is dependant on the motor’s thermal capacity.

This parameter should be set to a midrange value and then the Slow Speed Kick Time (CFN 27) parameter should be increased in 0.1 second intervals until the kick is applied long enough to start the motor rotating. If the motor does not start rotating then increase the Slow Speed Kick Level and begin adjusting the kick time from 1.0 seconds again.

LCD Display

PFN: Ph Loss Time 13 0.2 sec

Range 0.1 – 5.0 seconds (Default: 0.2)

Description The Phase Detect Delay parameter sets the delay time on Fault #27: "Phase Loss." This fault detects a loss of

proper phase timing even when the phasing remains valid; example: loss of line when the motor back generates a voltage. This allows a much faster detection than low line or no current at run faults.

Over Frequency Trip Level PFN 14

LCD Display

PFN: Over Frq Lvl 14 72 Hz

Range 24–72Hz(Default: 72)

Description The Over Frequency Trip Level parameter sets the highest line frequency that the starter will operate on.

When operating on line power, the default setting will usually suffice. If the application is speed sensitive, or the line power is suspect, the Over Frequency Trip Level parameter can be set to the highest acceptable frequency. When operating on generator power, the Over Frequency Trip Level parameter should be set to the highest acceptable frequency. This will ensure that a generator problem will not cause unnecessarily large fluctuations in the speed of the motor.

The frequency must be above the over frequency trip level setting for the Frequency Trip Time (PFN 16) parameter before the starter will recognize a high frequency condition. Once a high frequency condition exists, the starter will shut down and display a Fault #13, "High Freq Trip."

Description The Under Frequency Trip Level parameter sets the lowest line frequency that the starter will operate on.

When operating on line power, the default setting will usually suffice. If the application is speed sensitive, or the line power is suspect, the Under Frequency parameter can be set to the lowest acceptable frequency. When operating on generator power, the Under Frequency parameter should be set to the lowest acceptable frequency. This will ensure that a generator problem will not cause unnecessarily large fluctuations in the speed of the motor.

The frequency must be below the under frequency setting for the Frequency Trip Time (PFN 16) parameter before the starter will recognize an under frequency condition. Once an under frequency condition exists, the starter will shut down and display a Fault #12, "Low Freq Trip."

the motor. The thermistors will provide a second level of thermal protection for the motor. There is no PTC input required when set to "Off".

z NOTE: A motor PTC Fault #F05 occurs if resistance exceeds 3.5K ohm (+/- 300 ohms). The starter is locked out until the resistance drops below 1.65K ohm (+/- 150 ohms).

z NOTE: Open terminals will give an F05 fault immediately if this parameter is not set to "Off". The input is designed for DIN44081 and DIN44082 standard thermistors.

Independent Starting/Running Overload PFN 28

LCD Display

PFN: Indep S/R OL 28 Off

Range Off/On (Default: Off)

Description If “Off”

When this parameter is “Off” the overload defined by the Motor Running Overload Class parameter (QST 03) is active in all states.

If “On” When this parameter is “On”, the starting and running overloads are separate with each having their own settings. The starting overload class is used during motor acceleration and acceleration kick. The running overload class is used during all other modes of operation.

If both the running overload and the starting overload classes are set to "Off", then the existing accumulated motor OL% is erased and no motor overload is calculated in any state.

If the starting overload class is set to "Off" and the running overload class is set to "On", then the I overload does NOT accumulate during acceleration kick and acceleration ramping states. However, the existing accumulated OL% remains during starting and the hot/cold motor compensation is still active. The OL% is capped at 99% during starting.

Although there is really no reason to do so, the starting overload class could be set to "On" and the running overload class set to "Off".

Range LCD Description

Description The analog input is the reference input for a starter configured as a Phase Controller or Current Follower. In

Off Off, Disabled. (Default) Low Level Low, Fault if input signal below preset trip level. High Level High, Fault if input signal above preset trip level.

addition, the Analog Input Trip parameter allows the user to set a "High" or "Low" comparator based on the analog input. If the type is set to "Low", then a fault occurs if the analog input level is below the trip level for longer than the trip delay time. If the type is set to "High", then a fault occurs if the analog input level is above the trip level for longer than the trip delay time. This function is only active when the motor is running.

This feature can be used in conjunction with using the analog input as a reference for a control mode in order to detect an open 4-20mA loop providing the reference. Set the Analog Input Trip Type parameter to"Low" and set the Analog Trip Level parameter to a value less than (<) 20%.
