Preface

General Precautions

Qualified Personnel

ATT EN TI ON : Only qualified personnel familiar with adjustable frequency AC
drives and associated machinery should plan or implement the installation, start-up and subsequent maintenance of the system. Failure to comply may result in personal injury and/or equipment damage.

Personal Safety

ATT EN TI ON : To avoid an electric shock hazard, verify that the voltage on the
bus capacitors has discharged completely before servicing. Check the DC bus voltage at the Power Terminal Block by measuring between the +DC and -DC terminals, between the +DC terminal and the chassis, and between the -DC terminal and the chassis. The voltage must be zero for all three measurements.
Hazard of personal injury or equipment damage exists when using bipolar input sources. Noise and drift in sensitive input circuits can cause unpredictable changes in motor speed and direction. Use speed command parameters to help reduce input source sensitivity.
Risk of injury or equipment damage exists. DPI or SCANport™ host products must not be directly connected together via 1202 cables. Unpredictable behavior can result if two or more devices are connected in this manner.
The drive start/stop/enable control circuitry includes solid state components. If hazards due to accidental contact with moving machinery or unintentional flow of liquid, gas or solids exists, an additional hardwired stop circuit may be required to remove the AC line to the drive.

Product Safety

ATT EN TI ON : An incorrectly applied or installed drive can result in component
damage or a reduction in product life. Wiring or appl ication errors such as under sizing the motor, incorrect or inadequate AC supply, or excessive surrounding air temperatures may result in malfunction of the system.
This drive contains ESD (Electrostatic Discharge) sensitive parts and assemblies. Static control precautions are required when installing, testing, servicing or repairing this assembly. Component damage may result if ESD control procedures are not followed. If you are not familiar with static control procedures, reference Guarding Against Electrostatic Damage, publication 8000-4.5.2, or any other applicable ESD protection handbook.
Configuring an analog input for 0-20 mA operation and driving it from a voltage source could cause component damage. Verify proper configuration prior to applying input signals.
A contactor or other device that routinely disconnects and reapplies the AC line to the drive to start and stop the motor can cause drive hardware damage. The drive is designed to use control input signals to start and stop the motor. If an input device is used, operation must not exceed one cycle per minute or drive damage will occur.
Preface
Drive must not be installed in an area where the ambient atmosphere contains volatile or corrosive gas, vapors or dust. If the drive is not going to be installed for a period of time, it must be stored in an area where it will not be exposed to a corrosive atmosphere.

Accel/Decel Time

You can configure the drive’s acceleration time and deceleration time.

Acceleration Time

P535[Accel Time 1] and P536 [Accel Time 2] set the acceleration rate for all speed changes.

Adjustable Voltage

As standard AC drive applications are expanding into new markets, new control methods are required to meet these market demands for electromagnetic applications. Some of these applications, listed below, use non-motor or non­standard motors that require independent control of load frequency and voltage.
Vibration welding
Induction heating
Power supplies
Vibratory feeders or conveyors
Electromagnetic stirring
Resistive loads
Standard inverter control modes consist of volts per hertz (V/Hz), with boost selections, speed feedback selection, fan, pump, and economize, flux vector (FV), with encoder and encoder less modes. The control of the output voltage/ frequency relationship of the variable frequency inverter must be maintained in the linear and nonlinear (over-modulation) regions. Voltage linearity is achieved by maintaining a constant voltage/frequency ratio over the entire operating region. The variable frequency inverter must deliver an adjustable-frequency alternating voltage whose magnitude is related to the output frequency. As the linear-to-nonlinear transition begins, the control must compensate for the lost voltage and deliver a linear output voltage profile.
In adjustable voltage control mode, the output voltage is controlled independently from the output frequency. The voltage and frequency components have independent references and acceleration/deceleration rates.
The adjustable voltage control mode operation enables separate control of the output voltage and the output frequency for use on applications that are typically non-motor types. The voltage and frequency components have independent references and independent acceleration and deceleration rates. Both the voltage and frequency can be set to any point within their respective range. The following graph illustrates these functional ranges.

Chapter 1 Drive Configuration

Overview

Adjustable voltage control is enabled by setting P35 [Motor Ctrl Mode] to option 9 “Adj VltgMode.” This feature provides either three-phase and single­phase output voltage. The default mode is three-phase output voltage and is selected by P1131 [Adj Vltg Config]. In single-phase mode the drive is not designed to operate single phase motors, but rather the output load is considered to have a lagging or unity power factor consisting of resistance and inductance for specially designed motor or non-motor application.
Input reference sources can be configured from P1133 [Adj Vltg Select]. The input source can be scaled and upper when lower limits are applied. A trim source can be selected reference from P1136 [Adj Vltg TrimSel] with the trim voltage added or subtracted from the voltage reference.
The scalar frequency selection and scalar frequency ramp are the same components as used in all other control modes. The exception being the frequency command and ramp are decoupled from the voltage generation for the adjustable voltage control mode to provide an independent frequency ramp. Acceleration and deceleration rates and S Curve are the same as used in all other modes. Upper and lower limits are applied to the value of the output command frequency.
The adjustable voltage control voltage ramp provides an independent voltage ramp decoupled from the scalar frequency ramp and controlled by user selectable acceleration and deceleration ramp times. There is also an adjustable percent S Curve feature.
The current limit function reduces the output voltage when the current limit is exceeded. Minimum and maximum voltage limits are applied so the output voltage is never operated outside that range.

Adjustable Voltage Control Setup

The following examples of setups for the Adjustable Voltage Control mode are a starting point for configuration. Applications can be unique and require specific parameter settings. These examples are base case only.

Do not autotune.

Application Considerations

Whatever the device the user wants to connect to the drive by using the adjustable voltage feature, that device has some type of rating associated with it. As a minimum it needs to have a current rating and voltage rating. Drive selection is based on those ratings.
Sizing
First, consider the voltage rating of the drive. Determine what the available line voltage is and select a drive voltage rating to match. Next, select a drive that supplies the current necessary for the device’s rating.
Single Phase Output
Consult Rockwell Automation before configuring a drive for single phase adjustable voltage output. Derating of the drive is necessary because of stress on the DC bus capacitor or the IGBT switching losses. When PWM is applied to a resistor, the current changes state following the voltage. For each PWM voltage pulse the current is pulsing the same way. This rapid change in current is not designed into the IGBT selection for the drive. Therefore, some sort of derating needs to be applied. Somewhere around 67% derating. When in this mode, actual losses must be measured to determine a derating percentage. Adding a reactor in series with the resistor can help by adding inductance and rounding off the corners of the current pulses. Depending on how much inductance is added, the waveform can look like a sine wave.

This is a plot showing output voltage, output current, and DC Bus voltage. Here you can see the current following the voltage in a typical PWM output.
This plot enlarges some of the pulses to see the current and its shape.
Notice the tops have an abrupt change to them. Any rounding of the wave form at the top is due to the type of resistor used. The resistors used for this plot are the grid type resistors where the resistor element is coiled along its length, adding a certain amount of inductance. This inductance helps round over the leading edge of the current.

Below is the same plot with a reactor added in series. These waveform look like a sine wave and that is a function of how much inductance is added. However, the increased voltage drop must be accounted for.
Another option is to have a sine wave filter in the circuit. This lets unshielded cable to be used without the worry of PWM generated noise being injected into the facility. The cost of shielded cable versus a sine wave filter, Among other factors, has to be weighed.
When using single phase operation, connect the load to the U and V phases. The W phase is energized but is not used.
Enter your maximum current into the Motor NP Amps parameter. Also use this value in the Current Limit parameter. When started the drive attempts to ramp to the commanded voltage. If current limit is hit, the drive levels off or reduce the voltage to satisfy the current limit.
Notice the DC Bus voltage ripple in two of the plots above. If this ripple is high enough in magnitude, it can cause the drive to trip on an Input Phase Loss fault. This is due to the drive monitoring the bus ripple and if a certain delta between max volts and min volts exists for a certain amount of time, the drive assumes an input phase was lost. This fault can be disabled by setting P462 [InPhase LossActn] to option 0 “Ignore.”
Three Phase Output
If you are driving as resistive load, configure it in a three phase arrangement to avoid using the single phase mode of adjustable voltage. Use a sine wave filter to keep PWM off the resistors. If the resistors are of the ceramic type, it is possible to crack the resistor using PWM.

The following is a plot of voltage and current at the reactor. The output of the drive is sent through a sine wave filter then to the reactor. The shape of the waveform is determined by the amount of capacitance in the sine wave filter.
If you wanted to know what voltage you can expect at the three phase reactor, consider an example where the user has four reactors in series. The inductance of each is 1.2mH, 5mH, 5mH and 3mH. First item to calculate is XL for each
reactor. .
Now total it. XL1 + XL2 + XL3 + XL4 = 5.35 ohm.
For a three phase reactor the current is represented by the
equation,
Isolate the voltage.
The current value can be what the least rating of the reactors are or if the rating are greater than the drive rating, use the drive rating. In this case the drive is rated for 14 amps.

So 14 amps is realized when the voltage is 129.8 on the output. A drive with a voltage rating of 240V AC could be selected.
Below is a waveform of voltage and current at a resistor. The output of the drive runs through a sine wave filter. Then this is connected to a one to one transformer. This output is then sent to a bridge rectifier giving us pure DC. With the use of a feedback board and the drives PI loop, the voltage at the resistor was steady even if the resistance changed while running.

Auto Restart

Investigate Possible Derating
Derate drive for sine wave filter.
Motor or drive overload is not affected by adjustable voltage mode.
The Auto Restart feature provides the ability for the drive to automatically perform a fault reset followed by a start attempt without user or application intervention. Provided the drive has been programmed with a 2 wire control scheme and the Run signal is maintained. This enables remote or unattended operation. Only certain faults are allowed to be reset. Faults listed as Non­Resettable in the programming manual indicate possible drive component malfunction and are not resettable.
Use caution when enabling this feature, because the drive attempts to issue its own start command based on user selected programming.

Configuration

Setting P348 [Auto Rstrt Tries] to a value greater than zero enables the Auto Restart feature. Setting the number of tries equal to zero disables the feature.
ATT EN TI ON : Equipment damage and/or personal injury may result if this parameter is used in an inappropriate application. Do not use this function without considering applicable local, national and international codes, standards, regulations or industry guidelines.
Rockwell Automation Publication 750-RM002B-EN-P - September 2013 25
Chapter 1 Drive Configuration
P349 [Auto Rstrt Delay] sets the time, in seconds, between each reset/run attempt.
The auto reset/run feature supports the following status information.
P936 [Drive Status 2] Bit 1 “AuRstrCntDwn” provides indication that an Auto Restart attempt is presently counting down and the drive attempts to start at the end of the timing event.
P936 [Drive Status 2] Bit 0 “AutoRstr Act” indicates that the auto restart has been activated.

Operation

The typical steps performed in an Auto Reset/Run cycle are as follows.
1. The drive is running and an Auto Reset Run fault occurs, thus initiating the fault action of the drive.
2. After the number of seconds in P349 [Auto Rstrt Delay], the drive automatically performs an internal Fault Reset, resetting the faulted condition.
3. The drive then issues an internal Start command to start the drive.
4. If another Auto Reset Run fault occurs, the cycle repeats itself up to the
number of attempts set in P348 [Auto Rstrt Tries].
5. If the drive faults repeatedly for more than the number of attempts set in P348 [Auto Rstrt Tries] with less than five minutes between each fault, the Auto Reset/Run is considered unsuccessful and the drive remains in the faulted state.
6. If the drive remains running for five minutes or more because the last reset/run without a fault, or is otherwise stopped or reset, the Auto Reset/ Run is considered successful. The Auto Restart status parameters are reset, and the process repeats if another auto resettable fault occurs.
See Aborting an Auto-Reset/Run Cycle for information on how the Reset/Run cycle can be aborted.

Beginning an Auto-Reset/Run Cycle

The following conditions must be met when a fault occurs for the drive to begin an Auto Reset/Run cycle:
The fault type must be Auto Reset Run.
P348 [Auto Rstrt Tries] setting must be greater than zero.
The drive must have been running, not jogging, not auto tuning, and not
stopping, when the fault occurred. (A DC Brake state is part of a stop sequence and therefore is considered stopping.)
26 Rockwell Automation Publication 750-RM002B-EN-P - September 2013
Drive Configuration Chapter 1

Aborting an Auto-Reset/Run Cycle

During an Auto Reset/Run cycle the following actions/conditions abort the reset/run attempt process.
A stop command is issued from any source. (Removal of a 2-wire run-fwd or run-rev command is considered a stop assertion.)
A fault reset command is issued from any source.
The enable input signal is removed.
P348 [Auto Rstrt Tries] is set to zero.
A Non-Resettable fault occurs.
Power to the drive is removed.
The Auto Reset/Run Cycle is exhausted.
After all [Auto Rstrt Tries] have been made and the drive has not successfully restarted and remained running for five minutes or more, the Auto Reset/Run cycle is considered exhausted and therefore unsuccessful. In this case the Auto Reset/Run cycle terminates and an F33 “AuRsts Exhaust” fault is indicated by P953 [Fault Status B] Bit 13 “AuRstExhaust.”

Auto/Manual

The purpose of the Auto/Manual function is to permit temporary override of speed control and/or exclusive ownership of logic (start, run, direction) control. A manual request can come from any port, including HIM, digital input or other input module. However, only one port can own manual control and must release the drive back to auto control before another port can be granted manual control. When in Manual mode, the drive receives its speed reference from the port that requested manual control, unless otherwise directed by the Alternate Manual Reference Select.
The HIM can request Manual control by pressing the Controls key followed by the Manual key. Manual control is released by pressing the Controls key followed by Auto. When the HIM is granted manual control, the drive uses the speed reference in the HIM. If desired, the auto speed reference can be automatically preloaded into the HIM when entering HIM manual control, so that the transition is smooth.
Manual control can also be requested through a digital input. To do this, a digital input has to be set to request Manual control through P172 [DI Manual Ctrl]. Digital Input Manual control requests can be configured to use their own alternative speed reference to control the drive. Digital inputs can also be used in conjunction with Hand-Off-Auto Start to create a three way HOA switch that incorporates Manual mode.
The Safe Speed Monitor Option Module uses Manual mode to control the speed of the drive when entering Safe Limited Speed monitoring.
Rockwell Automation Publication 750-RM002B-EN-P - September 2013 27
Chapter 1 Drive Configuration

Auto/Manual Masks

The port configuration of the Auto/Manual feature is performed through a set of masks. Together, these masks set which ports can control the speed and/or logic control of the drive as well as which ports can request Manual control. The masks are configured by setting a 1 or 0 in the bit number that corresponds to the port (Bit 1 for port 1, Bit 2 for port 2, and so forth). Digital Inputs are always configured through Bit 0, regardless of what port the module physically resides in. If both [Manual Ref Mask] and [Manual Cmd Mask] for a particular port are set to 0, that port is unable to request manual control.
P324 [Logic Mask]
Logic Mask enables and disables the ports from issuing logic commands (such as start and direction) in any mode. Stop commands from any port are not masked and still stop the drive.
P325 [Auto Mask]
Auto Mask enables and disables the ports from issuing logic commands (such as start and direction) while in Auto mode. Stop commands from any port are not masked and still stop the drive.
P326 [Manual Cmd Mask]
Manual Command Mask enables and disables the ports from exclusively controlling logic commands (such as start and direction) while in Manual mode. If a port assumes Manual control, and the corresponding bit for the port in the [Manual Cmd Mask] is set, no other port is able to issue logic commands. Stop commands from any port are not masked and still stops the drive.
P327 [Manual Ref Mask]
Manual Reference Mask enables and disables the ports from controlling the speed reference while in Manual mode. If a port assumes manual control, and the corresponding bit for the port in the [Manual Ref Mask] is set, the drive is commanded to the speed reference from that port. An alternate speed reference can be commanded using P328 [Alt Man Ref Sel]. If the respective bit for the manual control port is not set, then the drive follows its normal automatic speed reference, even in Manual mode.

Alternate Manual Reference Select

By default, the speed reference used in Manual mode comes from the port that requested manual control (For example, if a HIM in port 1 requests manual control, the speed reference in Manual mode comes from port 1). If instead it is desired to use an a different speed reference, P328 [Alt Man Ref Sel], can be used. The port selected in the parameter is used for manual reference regardless of which port requested manual control, as long as the port in manual control is allowed to set the manual reference per P327 [Manual Ref Mask]. If P328 [Alt Man Ref Sel] is an analog input, the maximum and minimum speeds can be configured through P329 [Alt Man Ref AnHi] and P330 [Alt Man Ref AnLo].

HIM Control

Manual Control can be requested through an HIM device attached to port 1, 2, or 3. The proper bits must be set in the masks (P324 [Logic Mask], P326 [Manual Cmd Mask], and P327 [Manual Ref Mask]) for the port that the HIM
is attached. To request control through the HIM, press the (Controls) key to display the Control screen.
Press the (Manual) key.
Press the (Edit) key to confirm that you want to switch to Manual mode.
If the request is accepted, the HIM displays “MAN” in the top right corner. The display does not indicate if the drive is in Manual, but rather if that particular HIM has Manual control. A HIM still displays “AUTO” if it does not have ownership of the Manual mode, even if the drive itself is in Manual mode. To see if the drive is in Manual mode, check P935 [Drive Status 1] Bit 9.
When a HIM has Manual control of the drive, the drive uses the speed reference from the HIM unless overridden by P328 [Alt Man Ref Sel]. To change the speed reference on the HIM, navigate to the Status screen and press the middle soft key labeled REF.

HIM Preload
Before taking a manual control speed reference from a HIM, the drive can preload its current speed into the HIM to provide a smooth transition. Without this feature, the drive immediately transitions to whatever speed was last used in the HIM, before the operator has a chance to make their adjustment. With this feature, the drive maintains its current speed until the operator sets the speed to the desired manual reference.
