Installation
3.1 Control Installation
Elite Pro motor controls require mounting in an upright position in an area that will permit adequate airflow for cooling and ready access for making connections and for servicing. Because cooler air is drawn in from the bottom and exhausted from the top, these areas should be kept clear for about a six inch distance. Stacking of controls with one mounted above the other should be minimized so that the upper control is not ventilated with hot exhaust air from the lower control.
Enclosures should be sized to provide adequate surface area for dissipating heat or provided with forced ventilation with outside air from a duct system or enclosure fan. They should be mounted to a cool surface not exposed to heat generated by nearby equipment.
Excess ambient temperatures within enclosures can reduce the life expectancy of electronic components and can cause a heatsink over temperature fault on the Elite Pro control. Contact Carotron for assistance in sizing enclosures for particular horsepower ratings.
3.2 Wiring Guidelines
To prevent electrical interference and to minimize start-up problems, adhere to the following guidelines.
Make no connections to ground other than the designated terminal strip location.
Use fully insulated and shielded cable for all signal wiring. The shield should be connected at one end only to circuit common. The other end of the shield should be clipped and insulated to prevent the possibility of accidental grounding.
Signal level wiring such as listed above should be routed separately from high level wiring such as armature, field, and relay control wiring. When these two types of wire must cross, they should cross at right angles to each other.
Any relays, contactors, starters, solenoids or electro-mechanical devices located in close proximity to or on the same line supply as the motor control should have a transient suppression device such as an MOV or R-C snubber connected in parallel with its coil (for AC coils). Diode suppression should be used for DC coils. The suppressor should have short leads and should be connected as close to the coil as possible.

Terminal Connections & Functions
4.1 AC Power Connections & Fusing
Terminals L1, L2, and L3 are the AC line inputs for the armature power bridge. High speed semiconductor fuses must be provided externally. Refer to Figure 1 and Figure 2 on the next page and Table 21 in the Spare Parts Section on page 116 for common manufacturers and part numbers.
In most cases, the drive will use the internal field supply wiring scheme (Figure 1). The field bridge is powered from the auxiliary L1 and L2 output terminals via factory installed jumpers. However, in some cases, the field voltage required by a motor exceeds the maximum obtainable field voltage that can be produced using the required AC line voltage for the motor armature. In these cases, an external single phase AC supply for the field bridge must be used. The factory supplied terminal jumpers should be removed and the external supply connects to FL1 and FL2 (Figure 2). Note the external supply must be in phase with the L1 and L2 armature supply terminals.
7
Figure 1: Internal Field Supply Wiring
For example, consider the motor that has a rated armature voltage of 240VDC and a rated field of 240VDC. The rated armature voltage requires that an input supply of 230VAC be connected to L1, L2, and L3. However, the maximum field voltage attainable from the field bridge using the internal supply would be 200VDC. In order to obtain the required 240VDC field, an external single phase 460VAC supply (obtained via a transformer) can be connected to FL1 and FL2.
The drive also requires a fused single phase 115VAC control power on terminals L and N.
Carotron recommends the use of three phase DIT, drive isolation type transformers. While Elite Pro controls do not require these transformers for proper operation, they can be helpful in reducing the effects of line transients on this control and generated by this control on other products and can provide fault current limiting in the event of severe motor or control failure. Refer to Table 1 as a general guide in sizing line supply transformers and wiring.

4.2 Motor Connections
Field
Most motor fields consist of two windings that are connected in parallel for low voltage operation and in series for high voltage operation. Refer to Figure 3. The winding leads are individually marked and have a polarity that must be observed for proper and safe operation. Since direction of rotation is controlled by field polarity as well as armature polarity, it is sometimes more convenient to swap the smaller field leads when making corrections to the direction of rotation during initial installation. An energized field should never be switched by relay, contactor, switch or any other manual or electro­mechanical device.
In most cases, when the Elite Pro is supplied with 230VAC, the field should be wired for low voltage operation. When supplied with 460VAC, the motor field is typically wired for high voltage operation. The F1 and F3 leads should always have the same polarity regardless of the mode used.
9
Figure 3
Armature
The armature leads are usually the highest current wires associated with the drive and warrant special attention to sizing based on current rating as well as length of run. Extra care should be used where terminations and splices are made. Refer to Table 1 for typical armature voltage, current, contactor and dynamic braking resistor ratings. Figure 4 shows a typical armature wiring scheme using a contactor. An optional dynamic breaking resistor is also shown.
Figure 4
Series Field
When present, the S1 and S2 for the SERIES field winding is placed in series with the armature leads on non-regenerative models only! They should NOT be used with the EP4 Series regenerative models. On regenerative models, the leads should not be connected and should be individually insulated. On non-regenerative models the series field winding polarity must be kept at the same polarity as the shunt field winding, i.e. F1 and S1 the same, F2 (or F4) and S2 the same. If during startup the field windings are reversed to change direction of the motor, the series windings should also be reversed to maintain the proper polarity. Figure 5 shows a typical wiring scheme using the series field with a non-regenerative drive. Note the polarity of the shunt field and series field windings (S1 is positive with respect to S2, F1 is positive with respect to F2).
10
Figure 5
Motor Thermostat
Most motors include "J" or "P" leads that connect to an internal normally closed thermostat. Connecting the thermostat to TB1-38 & 39 as shown in Figure 6 will allow a motor over-temperature condition to shut down the control as in an Emergency Stop condition. If the motor does not provide a thermostat or the thermostat wiring is not used, a jumper must be placed across terminals 38 & 39.
4.3 Signal Connections
Figure 6 shows the typical signal connections to an Elite Pro drive. When operated, the Emergency Stop contacts at terminals 6 and 7 will immediately clamp all control signals. The armature contactor will also de-energize to disconnect the armature from the bridge output. Motor stopping time is determined by inertia and friction characteristics of the load and can be decreased by use of a brake resistor. Refer to Table 1 for recommended resistor values. If a maintained Emergency Stop push­button is used, the E-Stop Reset contacts at TB1-8 & 9 can be jumpered. Otherwise, a momentary push-button can be used to reset the E-Stop condition.
11
12
Figure 6: Signal Connections
The Elite Pro V3 supports three different start/stop logic schemes (four including the local mode). Refer to Figure 7 below. The momentary scheme (often called 3 wire) uses momentary pushbuttons to control the starting and stopping of the drive. A selector switch or a contact controls the direction. The other two schemes use maintained contacts (often called 2 wire mode). In the Run/Direction scheme, a single contact starts and stops the drive. Another contact selects direction. In the final scheme, each contact starts the drive and selects the direction. Parameter H1.01 needs to be set appropriately.
Figure 7
The drive also has the capability to interface with either sinking or sourcing logic controls. Sourcing (PNP) logic is selected by jumpering TB1 terminals 2 & 3. This places an internal pull down resistor on each input. The external switch or sensor must then drive the input high to activate the input. Sinking (NPN) logic is selected by jumpering TB1 terminals 1 & 2. This places an internal pull up resistor on each input. The external switch or sensor must then sink (pull down) the input to common to activate the input.

Human Machine Interface (HMI)
5.1 Description of Interface
The Human Machine Interface (HMI) is the primary method for accessing the drive's parameters. It allows for custom user configuration, monitoring, and troubleshooting. As seen in Figure 9, the HMI consists of a 4 line by 20 characters display, 11 button keypad, and 4 LEDs.

Table 3: Drive Monitor Descriptions
Programming The drive parameters are located under the Programming section. Each drive parameter has a unique identifier tag that consists of an alpha group code, and numeric block code, and a two digit numeric index. For example, parameter C2.04 is in Group C, Block 2, and Index 4. When the programming section is first displayed, the first parameter (A1.01) is displayed with the Group Code flashing (i.e. the 'A'). The Up/Down keys are then used to change the Group Code to the desired value. Pressing the Reset/Right key will move the cursor to the right and cause the Block Code to begin flashing. The Up/Down keys are then used to change the Block Code. Pressing the Reset/Right key will move the cursor to the right and cause the Index Code to begin flashing. Again, the Up/Down keys are used to change the Index to display the desired parameter. Pressing Escape will move the cursor left.
In order to simplify the menu, some parameters are hidden when they are not applicable. However, in some cases it may be desired to view these hidden parameters. There are two ways to view these hidden parameters. The first method is to change parameter A1.01 from STANDARD to ADVANCED. This makes all parameters visible. The second method is to use a certain keystroke while scrolling through the parameters. Pressing the F2 key before pressing the Up or Down keys will force the display to show the next/previous parameter (whether it is hidden or not).
Once a parameter is displayed, pressing the Enter key will allow its value to be modified. The current value of the parameter (or a digit in its value) will begin flashing. The Up/Down keys are used to adjust the value. If the parameter is a numeric value, the Reset/Right key can be used to shift the cursor to the right to allow other digits to be adjusted. Pressing the Reset/Right key when the cursor is on the last digit will cause the cursor to be placed on the first digit. Once the desired value is displayed, the value can be entered by pressing the Enter key. The Escape key will exit the parameter adjustment screen without changing the parameter value.
Note: When parameters are altered via the keypad, the changes are saved automatically.
Modified Parameters This section contains a list of parameters that have been modified from the default factory preset value. The Up/Down keys are used to scroll through the list.

Start Up Procedure
6.1 Pretest
1. Verify each phase of the 3 phase power supply. Input voltage should be checked ahead of the supplying circuit breaker, disconnect switch, etc. before it is switched on.
2. Connections should be visually inspected and checked for tightness. An ohmmeter can be used to check for ground faults. Ground faults in un-isolated circuits of the armature and field can cause fuse blowing and damage to the motor and control. To check for grounds with an ohmmeter, select a high resistance scale such as R x 100K ohms or greater. Test from each connection terminal (including shields) to chassis ground and be suspicious of any resistance reading less than 500K ohms. NOTE: An exception to this test would be made where the drive's 3 phase input is connected to a grounded "Y" type transformer secondary.
3. Adjust external reference (Analog Input 1) at terminal 10 to 0 volts.
4. Apply single phase control power and three phase bridge power. On initial power up, the drive should display an Invalid Motor Data fault. Press CLOSE to exit. When asked to run the Basic Setup Wizard, select YES. If the wizard was cancelled, it can be re-started
6.2 Adjustment Procedure: Velocity (Speed) Regulator
from the Wizards section in the menu.
1. Presets
Use the Basic Setup Wizard to set the required parameters. The wizard will step you through various drive parameters. When a parameter is displayed, press the ENT key to edit its value. There are a number of required parameters. The wizard will not allow you to proceed until a valid value has been entered. It is recommended that the drive initially be setup using armature feedback even if a tachometer or encoder will be used. This allows the proper feedback signal to be verified before using it for control. After the motor data is entered in the wizard, the drive should begin producing field output. Depending upon the wizard data entered, you may have the option to operate the field in either open or closed loop mode. After the field mode is selected, the wizard will display a field status screen showing the field voltage and field current. Verify the displayed values correspond to the motor nameplate. In many cases, when a motor is cold and the nameplate field voltage is applied, the field current will be much higher than its rated nameplate value. As the motor warms up, the field winding resistance should increase, which will cause the field current to decrease. If open loop was selected and the field output requires additional adjustment, press the ENT key while the status screen is displayed. This allows adjustment of Open Loop Reference (G3.03). Regardless of the mode, please ensure the field levels are correct before proceeding.
2. Clear any Faults
When the wizard is completed, the drive will try to clear any faults that are present. If a fault is still present (i.e. the Fault LED is on or flashing), navigate to the DM04 screen to display the current fault. Once the fault condition is removed, the fault can be cleared by pressing the RESET key while on any DM screen.
3. Validate E-STOP
When an E-STOP is activated, the status display on the DM01 screen should display E-STOP. When the E-STOP is cleared, the status should display STOP or FAULT. If E-STOP is always displayed, not all interlocks have been made. Please refer to the wiring diagram in Figure 6 on page 12. The 24V from terminal 38 should flow through all the interlocks to terminal 9. Do not proceed until the E-STOP functions properly.
4. Safety Check
During the following steps the motor will be rotated. If excessive speed or wrong direction of rotation could damage the load, it may be wise to de-couple the load until

5. Check Motor Rotation
6. Validate External Start/Stop
7. Validate Reverse Direction (optional, EP4 regenerative unit required)
8. Validate Tachometer Feedback (required only if a motor mounted tachometer is used)
9. Validate Encoder Feedback (required only if a motor mounted encoder is used)
proper control is verified.
While displaying the DM01 screen, place the drive in local mode by pressing the LOCAL/REMOTE key. The Local LED should be on. Press and hold the F1 key to jog the drive. The armature contactor should close and the motor should rotate slowly. Observe the direction of rotation. Release F1 to stop the drive. If the motor rotation is reversed, remove all power and reverse the motor armature or field wires. If used, observe proper polarization of the series field winding per the instructions in Section
4.2. After re-applying power, repeat this step to verify motor direction.
Press the LOCAL/REMOTE key to return the drive to Remote mode. The Local mode LED should be off. Adjust the external reference signal connected to terminal 10 to its minimum. Typically, the reference value on DM01 should be approximately zero. Place the drive in Run mode via the external contacts. Slowly increase the external reference until the motor is rotating. Issue a stop command using the external contacts and verify the motor stops and the contactor de-energizes.
With reference at minimum, run the drive in the reverse direction. Slowly increase the reference and verify motor runs in reverse direction. Stop drive.
Proper tachometer operation should be checked while the drive is running in Armature Feedback. Place the drive in run mode and run at a low speed (approximately 20%). On the display, navigate to DM10. Compare Armature feedback to Tachometer feedback. The values should be approximately equal (within 5%). If the values have approximately the same value but the wrong polarity, press the Stop button and invert the tachometer feedback by setting parameter F2.02 to On. Place the drive back in the run mode and re-check. If the values are not equal, verify the tachometer data is entered properly in section F2 (or the wizard) and jumpers J1-J3 are set properly. Once corrected and the values are equal at low speeds, increase speed and check at higher speeds. If the values are approximately equal throughout the speed range, the drive can be placed in the tachometer feedback. With the drive in the stop mode, set parameter G2.15 to Tachometer. Run drive and verify proper operation.
Proper encoder operation should be checked while the drive is running in Armature Feedback. Place the drive in run mode and run at a low speed (approximately 20%). On the display, navigate to DM10. Compare Armature feedback to Encoder feedback. The values should be approximately equal (within 5%). If the values have approximately the same value but the wrong polarity, press the Stop button and invert the encoder feedback by setting parameter F3.03 to On. Place the drive back in the run mode and re-check. If the values are not equal, verify the encoder data is entered properly in section F2 (or the wizard). Once corrected and the values are equal at low speeds, increase speed and check at higher speeds. If the values are approximately equal throughout the speed range, the drive can be placed in the encoder feedback. With the drive in the stop mode, set parameter G2.15 to Encoder. Run drive and verify proper operation.

6.3 Adjustment Procedure: Constant Horsepower
1. Presets
Set up the Elite Pro V3 drive as a normal velocity regulator to run at the motor's base speed using tachometer or encoder feedback with closed loop field control. Refer to Section 6.2 above. Once correct operation in this mode has been achieved, proceed
2. Parameters
3. Test
with the following steps.
Re-run the Basic Setup Wizard and set the Operating Mode to CONST HP (CROSSOVER). Continue through the wizard and enter additional motor data (specifically the extended speed field amps, and extended speed value). If tachometer is used, re-scale Jumpers J1-J3 as instructed by the wizard.
With reference at minimum, place drive in run mode. Navigate to DM03 and verify the motor field current is at the base speed level. Navigate to DM02 to display the armature voltage. Slowly increase reference until armature voltage is approximately 85% of the nameplate value (204V for 240V armatures, or 425V for 500V armatures). Return to DM03 and monitor the motor field current, while increasing the speed reference. The field current should begin decreasing as the speed reference is increased. When the maximum reference is applied, the field current should be approximately at the extended speed field current level. Return to DM02 and verify armature voltage is at the motor's rated armature voltage level.
6.4 Adjustment Procedure: Torque (Current) Regulator
1. Presets
Set up the Elite Pro V3 drive as a normal velocity regulator to run at the motor's base speed using armature feedback. Refer to Section 6.2. Once correct operation in this

3. Test
mode has been achieved, proceed with the following steps.
Re-run the Basic Setup Wizard and set the Operating Mode to TORQUE. Continue through the wizard and enter any required data.
With reference at minimum, place drive in run mode. Navigate to DM02 to display the armature current. Slowly increase reference and verify control of armature current.
6.5 Calibration & Fine Tuning
1. If the drive is using armature feedback (i.e. G2.15 is set to ARMATURE), then IR Compensation (G2.09) can be adjusted to improve the speed regulation with load changes. Adjustment is best done when the motor or machine can be loaded normally. If the motor is normally operated at a particular speed, adjust IR Compensation (G2.09) while running at that speed. If the motor operates under load over a wide speed range, pick a speed near mid-range to make the adjustment. Adjust as follows:
Operate the unloaded motor at the normal or mid-range speed and note the exact speed using a hand tachometer or other speed measuring device. While still monitoring speed, apply normal load. The reduction in speed of a fully loaded motor will usually fall between 2 and 13% of rated or "base" speed. Slowly increase IR Compensation (G2.09) until the loaded speed equals the unloaded speed measured in the previous step. Making this adjustment may now cause the unloaded speed to be slightly higher. Repeat this procedure until there is no difference between loaded and unloaded speed levels. Use care not to set the adjustment too high or speed increase with load and instability may result. NOTE: For this adjustment, do not use armature voltage feedback (AFB) to measure speed. Armature voltage is not an exact indication of loaded motor speed!

2. The Current Proportional Gain (G1.16), Current Integral Time (G1.17), Velocity Proportional Gain (G2.21), and Velocity Integral Time (G2.22) parameters are preset by Carotron to provide stable and responsive performance under most load conditions. When required, the drive performance can be optimized for a particular application or to correct undesirable operation by use of these adjustments. The adjustments are complex though and can adversely affect operation if not properly set. In general, the settings that give the most stable operation do not always give the fastest response.
Current Loop
The current loop can be manually tuned by directly applying a stepped reference and monitoring the current feedback. In order to adjust properly, connect an oscilloscope between common and the A.IFB testpoint on the control board. The rotor shaft must not rotate during this procedure. Therefore, set Field Enable (G3.01) to DISABLE to remove voltage from the shunt field. Set Reference Select (G1.01) to STEP. Set the Step Reference (G1.22) initially to a low value (around 20%). Set the Step Duration (G1.23) to 500ms. Place the drive in the run mode. Set Step Enable (G1.24) to ENABLE to apply a step change to the PI loop. The current feedback signal should respond quickly with minimum overshoot. Adjust the Current Proportional Gain (G1.16) and Current Integral Time (G1.17) parameters and re-apply the Step Enable until a critically damped waveform as seen in Figure 11. Increasing the proportional gain improves the response but increases the overshoot. Reducing the integral time improves the response but can cause instability if set too low. Once a critically damped waveform is obtained, increase the Step Reference to 40% and repeat above. Continue until a Step Reference of 100% is achieved. Return Field Enable (G3.01) to ENABLE and Reference Select (G1.01) to NORMAL when complete.
Velocity Loop
In order to adjust properly, connect an oscilloscope to Analog Output 1 Terminal 21 (Velocity Feedback). Using the HMI, temporarily set the Reference Select (G2.29) to STEP. Set Step Reference (G2.30) to 20% and Step Duration (G2.31) initially to 2 seconds. Place the drive in the run mode and apply a step change by setting Step Enable (G2.32) to ENABLE. Observe the response of the drive on the oscilloscope. The motor speed should respond quickly with minimum overshoot. Adjust the Velocity Proportional Gain (201) and Velocity Integral Time (202) parameters to obtain a critically damped waveform as seen in Figure 12. Increasing the proportional gain improves the response but increases the overshoot. Reducing the integral time improves the response but can cause instability if set too low. Repeat above in steps gradually increasing the Step Reference to 100% (or the max required speed is obtained). Once complete, return Reference Select (G2.29) to NORMAL.

6.4 Password Protection
If password protection is required, set the appropriate password under A1.04. Please note that this is a special hidden parameter. You must first display A1.03. Then press F2 key and then the Up key to display A1.04. Once A1.04 has a value other than zero, parameters can be viewed but cannot be changed. Changes can only be made by first entering the password into parameter A1.05. Once all changes have been made, A1.05 can be manually returned to 0 to logout. The drive also has a timeout feature, that automatically clears the entered password in A1.05 after 5 minutes.

Programming & Adjustments
Programming and adjustment of the Elite Pro is accomplished by changing parameter settings. Each parameter has a Tag identifier and a descriptive name. Parameters are separated into groups and blocks according to their function. The following sections contain each software block diagram and descriptions of each parameter function. Refer to Figure 13 for key conventions that are used in the block diagrams. Each parameter is one of three types: Read-Write (RW), Inhibit Change while Running (ICR), or Read­Only (RO). ICR parameters can be changed only when the drive is not running.
7.1 A: Options
These parameters set the drive's basic operating mode.
A1: Options
A1.01 Parameter Visibility (R/W, Preset: Standard)
When set to Standard, parameters that are typically not relevant to the current operating mode are hidden. When set to Advanced, all parameters are visible.
A1.02 Operating Mode (ICR, Preset: Velocity)
Sets the drive's operating mode.
VELOCITY
A1.03 Initialize (ICR, Preset: 0)
9999: Re-initializes the drive and returns all parameters to the factory default setting. Range: 0..65535
A1.04 Define Password (R/W, Preset: 0)
A numeric password may be set to prevent unauthorized parameter changes. After a numeric password has been entered, the drive allows all parameters to be viewed, but prevents changes from being made. Only after a valid password has been entered into A1.05 can changes be made. This parameter requires a special keystroke to display. With A1.03 displayed, press F2 and then UP. Range: 0..65535
A1.05 Enter Password (R/W, Preset: 0)
If a numeric password has been defined in parameter A1.04, the same password must be entered into parameter A1.05 before any parameter changes can be made. As a security feature, the drive automatically clears the entered password after 5 minutes. Parameter A1.05 is typically only visible after a password is defined in parameter A1.04. Range: 0..65535
Drive regulates motor speed.
CONST HP (CROSOVER)
Drives regulates speed utilizing the motor's extended speed range. Also known as field weakening or field crossover.
