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.

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.
Wizards
This section contains various drive related wizards that aid in drive setup.

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
17
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
2. Parameters
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!
19
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.

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.

This parameter is only used when in the SONIC INPUT mode. Range: 0..420"
B8.10 Freq Input Bias (R/W, Preset: 0.00)
Defines the value of the target parameter when the input signal is less than or equal to the 0%
Calibration. Note that the formatting of this parameter will change to match that of the target
parameter. For example, if the target parameter is in percent, this parameter will be in percent. If
the target parameter is True/False, this parameter will be True/False.
B8.11 Freq Input Gain (R/W, Preset: 100.00)
Defines the value of the target parameter when the input signal is greater than or equal to the
100% Calibration. Note that the formatting of this parameter will change to match that of the
target parameter.
B8.12 Freq Input Polarity (R/W, Preset: Positive)
Defines the polarity of the target parameter. When set to POSITIVE, the target parameter will
have a positive value. Likewise, when set to NEGATIVE, the target parameter will be negative.
B8.13 Out of Range (RO)
Displays the status of the sonic transducer distance measurement. If B8.04 is 10% less than
B8.08 or B8.04 is 10% greater than B8.09, this parameter will be TRUE indicating the target is
out of range.
B8.20 Counter Destination (ICR, Preset: 00.00 [Not Set])
The drive has a counter associated with the frequency input. This count value can control (or
write to) any R/W parameter in the drive. The destination parameter contains the tag of the
parameter the input will control (i.e. the target parameter).
B8.21 Counter Enable (R/W, Preset: Disabled)
The counter is enabled when set to ENABLED.
B8.22 Counter Direction (R/W, Preset: Up)
Controls the direction of the counter. When set to UP, each pulse on the input will cause the
counter (B8.26/27) to increase. When set to DOWN, each pulse on the input will cause the
counter to decrease.
B8.23 Rollover Enable (R/W, Preset: Disabled)
When ENABLED, the counter is allowed to rollover from maximum to minimum when counting
up, or to rollover from minimum to maximum when counting down. If DISABLED, rollover is not
allowed and the count value will stop and hold its value at the maximum or minimum.
B8.24 Counter Reset (R/W, Preset: Off)
Resets the counter (B8.26/27) to the Reset Value (B8.24/25) when ON.
B8.25 Reset Value Lo (R/W, Preset: 0)
B8.26 Reset Value Hi (R/W, Preset: 0)
The 32 bit counter will be preset to the value in these two registers when B8.23 is ON.
B8.27 Counter Lo (RO)
B8.28 Counter Hi (RO)
The 32 bit counter is split into two 16 bit sections (B8.28:B8.27). The counter has a maximum
value of 4,294,967,295.
B8.29 Divisor (ICR, Preset: 1)

filtering) to 15 (heavily filtered). Range: 0..15
C1.05 Analog Input 1 Type (ICR, Preset: Voltage)
Configures the type of analog input signal used, either VOLTAGE or CURRENT.
C1.06 Analog Input 1 Unipolar 0% Calibration (R/W, Preset: 0)
Defines the minimum signal level in UNIPOLAR mode. An input value below this level will be
ignored. Refer to Figure 24. Range: 0..4095
C1.07 Analog Input 1 Unipolar 100% Calibration (R/W, Preset: 4095)
Defines the maximum raw signal level in UNIPOLAR mode. An input value above this level will
be ignored. Refer to Figure 24. Range: 0..4095
C1.09 Analog Input 1 Bipolar 100% Calibration (R/W, Preset: 2047)
Defines the maximum raw positive and negative signal levels in BIPOLAR mode. Any input
value exceeding this level will be ignored. Refer to Figure 24. Range: 0..2047
C1.10 Analog Input 1 Bias (R/W, Preset: 0.00)
Defines the value of the target parameter when the input signal is less than or equal to the 0%
Calibration. Refer to Figure 24. Note that the formatting of this parameter will change to match
that of the target parameter. For example, if the target parameter is percent, this parameter will
be percent. If the target parameter is Seconds, this parameter will be Seconds.
C1.11 Analog Input 1 Gain (R/W, Preset: 100.00)
Defines the value of the target parameter when the input signal is greater than or equal to the
100% Calibration. Refer to Figure 24. Note that the formatting of this parameter will change to
match that of the target parameter.
