Electrical Installation
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Turn off all power (main and remote) before installing the equipment.
Refer to “Before You Begin” starting on page 8 for important information
and precautions.
Failure to follow these instructions will result in death or serious
injury.
General Wiring PracticesBefore wiring the drive, perform the DC Bus Voltage Measurement
Procedure on page 40. Good wiring practice requires the separation of
control circuit wiring from all power wiring. Power wiring to the motor must
have the maximum possible separation from all other power wiring, whether
from the same drive or other drives.
Do not run power and/or control or multiple power wiring in the same
conduit. This separation reduces the possibility of coupling electrical
transients from power circuits into control circuits or from motor power wiring
into other power circuits.
CAUTION
IMPROPER WIRING HAZARD
Follow the wiring practices described in this document in addition to those
already required by the National Electrical Code
Failure to follow these instructions can result in injury or equipment
damage.
Follow the practices below when wiring the S-Flex enclosed drive:
®
and local codes.
•Use the supplied knockouts to feed control wiring into the cabinet. Do
not run control wires through the drive vents or rear air intake.
•Use metallic conduit for all drive wiring. Do not run control and power
wiring in the same conduit.
•Separate metallic conduits carrying power wiring or low-level control
wiring by at least 3 inches (76 mm).
•Separate existing, non-metallic conduits or cable trays used to carry
power wiring from metallic conduit carrying low-level control wiring by at
least 12 inches (305 mm).
•Whenever power and control wiring cross, the metallic conduits and
non-metallic conduits or trays must cross at right angles.
•Equip all inductive circuits near the controller (relays, contactors,
solenoid valves) with noise suppressors.
Input PowerThe S-Flex enclosed drive operates from a three-phase supply connected to
the input of the controller. The disconnect is coordinated and tested with the
controller power circuit for a short circuit current rating of 100,000 A.
Rev. 02, 12/2012Section 3—Installation and Start-up
Branch Circuit ConnectionsSize all branch circuit components and equipment such as feeder cables,
disconnect devices, and protective devices according to the National
Electrical Code and applicable local codes based on the drive input current
or motor full load current (whichever is greater).
The input current and drive controller rated FLA are printed on the
nameplate (see Figure 1 on page 12). Refer to Table 3 on page 13 for drive
controller input currents. Refer to Tables 10 and 11 (page 47) for lug data
and wire range of drive controller input terminals L1, L2, and L3.

edition), “Safety Standards for Construction and Guide for Selection, Installation and Operation
of Adjustable-Speed Drive Systems.”
WARNING
.
The high frequency equipotential grounding connection between the drive,
motor, and cable shielding does not eliminate the need to connect the
grounding (PE) conductors (green-yellow) to the appropriate terminals on
each unit. To help accomplish this, follow these guidelines:
•To avoid communication interference, grounds between the drive, motor
and cable shields must have high frequency equipotentiality.
•When using shielded cable for the motor, use a 4-conductor cable so
that one wire will be the grounding connection between the motor and
the drive. Size the grounding conductor in compliance with local and
national codes. The shield can then be grounded at both ends. Metal
ducting or conduit can be used for part or all of the shielding length,
provided there is no break in continuity.
•When using shielded cable for control signals, if the cable is connecting
equipment that is close together and the grounds are bonded together,
then both ends of the shield can be grounded. If the cable is connected
to equipment that may have a different ground potential, then ground the
shield at one end only to prevent large currents from flowing in the
shield. The shield on the ungrounded end may be tied to ground with a
capacitor (for example: 10 nF, 100V or higher) in order to provide a path
for the higher frequency noise.
•Ensure maximum separation between the power supply cable (line
supply) and the motor cable and also ensure maximum separation
between the control cables and any power cables.
Connecting the motor ground wire directly to the power converter chassis as
shown in Figure 15 (page 38) is the preferred grounding method. This
method reduces the amount of high frequency noise generated by the
power converter PWM that may be coupled into communication or control
wiring. The drive has two or more marked terminals for making grounding
connections.
Output WiringSize theampacity of motor power conductors according to the motor full
load current, National Electrical Code, and applicable local codes.
Connect motor conductors to the lugs provided and connect the motor
ground to the power converter chassis. Connect motor conductors to T1,
T2, and T3 on the overload relay when the controller is supplied with a
bypass circuit. Connect motor conductors to T1/U, T2/V, and T3/W on the
power converter, or T1, T2, and T3 on the distribution block (if supplied),
when the controller is supplied without a bypass circuit. See Figure 16 on
page 44.
The drive is sensitive to the amount of capacitance (either phase-to-phase
or phase-to-ground) present on the output power conductors. If excessive
capacitance is present, the drive may trip on overcurrent.
Output CableFollow these guidelines when selecting output cable:
•Cable type: select cable with a low capacitance phase-to-phase and to
ground. Do not use mineral-impregnated cable because it has a very
high capacitance. Immersion of cables in water increases capacitance.
•Cable length: the longer the cable, the greater the capacitance. Cable
lengths greater than 164 ft (50 m) may appear as a ground fault
condition to the drive. For installations where cable capacitances may be
a problem, a reactor or motor protection filter can be installed between
the drive and the motor.
The following guidelines are designed to address maximum cable length for
typical drive/motor applications.
These limits are based on the maximum recommended peak voltage that
can be allowed at the motor terminals, which is due to the reflected wave
phenomenon. This increase in voltage is primarily determined by the degree
of impedance mismatch between the power conductor and the motor in
combination of the dV/dt of the specific semiconductors used in the inverter
section of the drive feeding the motor, both of which vary depending on the
horsepower involved.
•Many variables can affect the performance of the drive, the motor, and
the cables in long lead applications. Motor protection filters can provide
substantial benefits when you are using:
— 460 V or higher rated AC drives
— Existing general purpose motors subject to retrofit to an AC drive
— Shielded cables
•NEMA MG-1 Part 31 compliant motors are recommended but not
required. However, consult the motor manufacturer or vendor literature
to address any specific limitations governing the application.
— Proximity to other output cables: because of high frequency
switching and increased capacitance, the drive may trip under some
conditions.
— Do not use lightning arrestors or power factor correction
capacitors on the output of the drive.
For proper drive short circuit protection, certain values of inductance may be
required in the output power wiring. Inductance can be supplied by the
power wiring or auxiliary inductors.
Section 3—Installation and Start-upRev. 02, 12/2012
CAUTION
INSUFFICIENT OUTPUT INDUCTANCE
Provide at least 500 mm (20 in.) of cable at the drive output (U/T1, V/T2,
W/T3) to help protect the drive output when short circuits occur.
Failure to follow these instructions can result in injury or equipment
damage.
The S-Flex enclosed drive is not intended to be used where extremely long
output cable runs are required. Maximum output cable length for standard
duty motors should be limited to 100 m (328 ft). For applications exceeding
this cable length, consult the factory.
DC Bus Voltage Measurement Procedure
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Read and understand the DC Bus Voltage Measurement Procedure
before performing the procedure.
• Measurement of bus capacitor voltage must be performed by qualified
personnel.
• Apply appropriate personal protective equipment (PPE) and follow safe
electrical work practices. See NFPA 70E.
• DO NOT short across terminals PA/+ and PC/– or across the DC bus
capacitors.
• DO NOT touch unshielded components or terminal strip screw
connections with voltage present.
• Use only electrically insulated tools.
• Before servicing the drive:
— Disconnect all power including external control power that may be
present.
— Always use a properly rated voltage sensing device to confirm
power is off.
— Place a “DO NOT TURN ON” label on all power disconnects.
— Lock all power disconnects in the open position.
— WAIT 15 MINUTES to allow the DC bus capacitors to discharge.
Then follow the “DC Bus Voltage Measurement Procedure” below to
verify that the DC voltage is less than 42 V. The drive LED is not an
indicator of the absence of DC bus voltage.
• Replace all devices, doors and covers before turning on power to this
equipment or starting and stopping the drive.
Failure to follow these instructions will result in death or serious
injury.
The DC bus voltage level is determined by monitoring the PA/+ and PC/–
terminals. The location of these terminals varies by power converter model
number. Read the model number of the power converter from the
nameplate, and identify the corresponding PA/+ and PC/– terminals. See
Figure 1 on page 12.
1. Remove all power from the drive. Use a properly rated voltage sensing
device to confirm power is off. Also, be sure to remove all external
control power that may be present such as on the control board and the
option board terminals.
2. Open the disconnect between the input line and the drive. Lock the
disconnect in the open position and install a “Do Not Turn On” sign.
Open the circuit breaker disconnect located on the front of the drive. Be
sure to remove all external control power that may be present, such as
on the control board and the option board terminals.
3. Wait fifteen minutes for the DC bus capacitors to discharge.
4. Open the door of the drive.
5. Set the voltmeter to the 1000 Vdc scale. Measure the voltage between
the PA/+ and PC/– terminals.
6. Verify that the DC bus voltage has discharged below 42 V before
servicing the drive. If the DC bus capacitors will not discharge below
42 V, contact your local Schneider Electric representative. Do not
operate the drive.
7. After servicing the drive, close and secure door.

Wire Routing and Interconnection
Wire ClassThe Wire Class describes the compatibility of the field wiring terminal with
the conductor material and insulation system. When used in conjunction
with the required conductor current rating and the controller ambient
temperature rating, the Wire Class forms the basis for selecting a conductor
size that limits the temperature on the conductor insulation at the field wiring
terminal to acceptable limits. Conductors with operating temperatures
exceeding those given by the Wire Class can be used, but the conductor
size must be selected based on the Wire Class limits.
Noise ClassThe Noise Class categorizes the electromagnetic properties of the voltages
and currents present. The six Noise Class categories determine proper
wiring methods and physical segregation.
Quiet Wiring 1 (QW1)High-susceptibility analog and digital control signals. Signals falling under
the classification of QW1 include digital communication/network circuits,
controller analog I/O and analog process signals.
Quiet Wiring 2 (QW2)Medium-susceptibility analog and digital control signals. Signals falling
under the classification of QW2 include 24 Vdc and 24 Vac control circuits.
Standard Wiring 1 (SW1)Low-Susceptibility control or power circuits rated less than
600 Vac (250 Vdc) and less than 15 A (voltage and current spectra are
generally contained within 0.05–9 kHz). Signals falling under the
classification of SW1 include 120 Vac control circuits.
Standard Wiring 2 (SW2)Power circuits rated greater than 15 A (voltage and current spectra are
generally contained with 0.05–9 kHz). Signals falling under the classification
of SW2 include line power to controllers.
Standard Wiring 3 (SW3)Reserved.
Pulse Wiring 1 (PW1)Control or power circuits whose voltage or current spectra significantly
exceed 9 kHz. Signals falling under the classification of PW1 include motor
and dynamic braking circuits fed from PWM (pulse width modulation) power
converters.
Voltage ClassThe Voltage Class groups the voltages present into recognized conductor
insulation categories (30,150, 300, and 600 V) for selection of conductor
insulation voltage rating and physical segregation.
Wiring Methods
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Route and secure all conductors to prevent damage to insulation when
installing them under or near sharp edges.
• When possible, use jacketed conductors.
Failure to follow these instructions will result in death or serious
injury.
Based on the Noise Class and Voltage Class of the conductors, apply the
wiring methods in Table 8 to the drive.
1. Bundle all conductors of 1- or 3-phase AC power circuits to minimize stray magnetic fields.XXX
2. Bundle all conductors of a DC power circuit to minimize stray magnetic fields.XXX
3. When parallel conductors must be run in separate wireways or conduit, bundle the conductors into groups to minimize stray
magnetic fields.
4. Maintain conductor runs that are as short and direct as possible.XXXXX
Separation of Circuits
1. Do not run different Noise Class conductors in the same conduit.XXXXX
2. Do not run different Voltage Class conductors in the same conduit unless all conductors are insulated for the maximum
Voltage Class present.
3. Separate all conductors by Noise Class.
Use the following circuit separation when conductors run parallel for more than 12 inches.
• Metallic conduit: 3 in. from QW to SW or PWXXXXX
• Metallic tray: 3 in. from SW to PWXXX
• Metallic tray: 6 in. from QW to SW or PWXXXXX
• Against continuous metal surface: 3 in. from SW to PWXXX
• Against continuous metal surface: 6 in. from QW to SW or PWXXXXX
• Metallic conduit housing QW: 12 in. to non-metallic conduit SW or PWXXXXX
• Non-metallic conduit: 3 in. from SW to PWXXX
• Non-metallic conduit: 23 in. from QW to SW or PWXXXXX
4. All PW conductor groups must be individually separated using metallic conduit.X
5. If QW and SW1 wiring must cross SW2 or PW1 wiring, cross the bundles at right angles.XXXXX
Common Mode Noise Issues
1. Provide adjacent signal returns using twisted pair cable.XX
2. Galvanically isolate the signal and the associated signal return path when possible.XX
Shielding
1. Use metallic conduit for all power and control circuits external to the controller enclosure.XXXXX
2. Use shields that are continuous and equipped with a drain wire.XXX
3. Do not group different Noise Class conductors within the same shield.XXXXX
4. Minimize the non-shielded portion of the conductor at the end of the shielded cable.XXXXX
5. When shielding AC or DC power conductors, group the conductors to minimize the magnetic field in the shield.XXX
Grounding
1. Ground shields only at the controller end.XXXXX
2. Use a separate ground wire for each shield ground.XXXXX
3. Provide a ground wire with all conductor groups, whether in tray or conduit.XXX
4. When multiple grounds must be made to a shielded power cable, the shield must have the same short circuit withstand
capability as the grounding conductor in the power cable.
5. Terminate all power grounds and power shield grounds to the controller grounding point or power converter chassis.XXX
6. Terminate all signal shield grounds to the terminals provided.XX
7. Always supply a separate equipment grounding conductor with the controller power feed. Do not depend on metallic conduit
for the grounding connection.

WARNING
LOSS OF CONTROL
Changes to factory set parameters must be completed in the sequence of
appearance in Table 16 on page 60.
Failure to follow these instructions will result in death, serious
injury, or equipment damage.
For power circuit Y with full voltage bypass, the S-Flex enclosed drives
operate either by the power controller or at full-speed, full-voltage bypass.
You can run the motor in bypass mode in the unlikely event that the power
converter becomes inoperative.
The S-Flex enclosed drives consist of:
•An IEC-rated drive output and bypass contactor with electrical interlock
and Class 10 overload relay
•A 120 Vac control power transformer (CPT)
•A Square D™ brand circuit breaker disconnect or fusible disconnect with
the ability to lock in the open position
•An AFC-Off-Bypass switch
•A power converter
Always verify that the overload relay is set to the motor full load current.
Power Circuit W Without BypassFor power circuit W without bypass, the S-Flex enclosed drives operate by
the power controller only. This power circuit consists of a circuit breaker
disconnect with means for locking in the open position, power convertor,
and optional equipment as specified.
Operator Controls – General
Arrangement and Operation
Operator controls are located on the front of the power converter and the
control rail for Bypass Power Circuit Y. AFC-Off-Bypass switch and
indicators are not supplied with Non-Bypass Power Circuit W.
The AFC-Off-Bypass switch allows selection of power converter operation
of the motor (AFC position) or line power operation of the motor (Bypass
position).
UNINTENDED EQUIPMENT OPERATION
Before turning on the drive or upon exiting the configuration menus,
ensure that the inputs assigned to the Run command are in a state that
will not cause the drive to run. Otherwise, the motor can start immediately.
Failure to follow these instructions will result in death, or serious
injury.
AFC OperationAFC operation allows control of the motor with the power converter. To set
the S-Flex drive to AFC operation, close the controller disconnect switch
located on the front of the drive and place the AFC-Off-Bypass switch (if
used) in the AFC position.
The power converter can be operated either locally or remotely depending
on the Loc/Rem key setting (integrated keypad) or F4 key setting (graphic
keypad). When using the integrated keypad, if the green LED above the
Loc/Rem key is illuminated, the power converter is operating in local mode.
When the green LED is not illuminated, the power converter is operating in
remote mode. When using the graphic keypad, LOCAL or REMOTE is
displayed above the F4 key.
•In local mode, the keypad Run and Stop keys can be used to start and
stop the drive. Speed can be adjusted by pressing the UP and DOWN
arrows on the integrated keypad, or by turning the Jog dial on the
graphic keypad. The speed displays as output frequency in hertz.
•In remote mode, a run command and the speed reference signals can
be sent to the power converter using either the logic input terminals or a
serial communication network.
— Control through the logic input terminals is the default factory
setting when no communication options are selected. Start/stop
functionality is available through the user-supplied auto start contact
between TB1–P24 and TB1–F. Adjustable speed reference signals
are sent through the analog input terminals VIA or VIB. The speed
displays as output frequency in hertz.
The RJ-45 Modbus port is configured for monitoring only as a factory
default. See Table 16 on page 60 for Modbus control information.
— Control through serial communication is the default factory
setting when a communication option is selected. The power
converter responds to the run command and speed reference
signals over the serial communications network. See Table 16 on
page 60 for information about monitoring only through serial
communications.
The RJ-45 Modbus port is occupied when graphic keypad (D07) is
selected.
Bypass OperationBypass operation allows control of the motor with line power. To set the
S-Flex drive to bypass operation, close the controller disconnect switch
located on the front of the drive and place the AFC-Off-Bypass switch in the
Bypass position. This transfers motor operation to line power, full speed
operation. Moving the selector switch to the Off position opens the bypass
contactor and stops the motor.
Freeze/Firestat Interlocks (If Used)Terminals TB1-2 and TB1-4 accept a user-supplied, normally-closed (N.C.),
freeze/firestat interlock. Remove the factory-installed jumper from the
terminals before installing the interlock. If the connection between terminals
TB1-2 and TB1-4 is open, the drive output contactor and the drive bypass
contactor will open and cause the motor to coast. This feature can be used
in conjunction with freeze sensors or in a firestat control system in
accordance with NFPA (National Fire Protection Association) and local
codes.
Pilot LightsPilot lights visually indicate protective functions and circuit status. The LED
ratings for the pilot lights is 120 Vac.
The functions of the two pilot lights are:
•Power On (red): illuminates when the drive disconnect is turned on.
When pilot lights are not supplied, Power On is indicated by illumination
the of power convertor display.
•Bypass Run (green): illuminates while the drive is operating in bypass
mode.
Pilot Lights are not available with Non-Bypass Power Circuit W.
Auxiliary Drive Run ContactProvides a normally-open (N.O.) contact between terminals TB1–11 and
TB1–12 that closes when the motor is running in drive mode.
Not available with communications options.
Auxiliary Bypass Run ContactProvides an N.O.contact between terminals TB1–13 and TB1–14 that
closes when the bypass contactor is closed and the motor is running in
bypass mode.
Auxiliary Detected Fault ContactProvides an N.C. contact between TB1–15 and TB1–16. Upon successful
converter start-up, the contact will open and remain open until the drive
detects a fault or is powered down.
Damper ControlAvailable only for S-Flex drives with the integral full voltage bypass circuit.
To enable damper control, remove the jumper between terminals 3 and 4,
and make appropriate connections to terminals 3, 4, 5, 6, 19, and 20.
AFC ModeIn AFC mode, if the drive is powered and in remote mode of operation,
before starting the motor a customer-supplied auto start command contact
closure between terminals 5 and 6 is required. When the auto start signal is
provided, a dry relay contact closure occurs between terminals 19 and 20
that can be used by the customer to energize a damper actuator motor to
open louvers that are closed when the controller is off.
NOTE: The power for the damper motor must be supplied separately by the
user.
When the damper reaches an Open position, the damper end switch must
close to provide feedback to the drive. The drive will then run the motor. The
drive will continue to run until the auto start signal is removed or the damper
end switch is no longer engaged. When damper control is enabled, the fan
motor will freewheel stop when the auto start signal, damper end switch or
other installed interlocks are removed.
Bypass ModeWhen the S-Flex drive is set to BYP mode, the signal to power open the
damper louvers is immediately made. When the damper end switch
feedback is made, the bypass contactor will close. The motor will accelerate
and run at line frequency speed until the Bypass is turned to off, the damper
end switch made signal is lost, or any other installed interlocks are removed.
Smoke Purge Function (Fireman’s
Override)
Provides a smoke purge function which is controlled by a user-supplied,
120 Vac signal between terminals TB1–17 and TB1–18. Supplying 120 Vac
to TB1–17 and TB1–18 transfers the motor operation to line power (if not
operating in this mode already). This feature can be used in powered,
smoke extract systems designed in accordance with NFPA and local codes.
The Smoke Purge Function is not available with Non-Bypass Power Circuit W.
To disable the smoke purge function, remove the jumper between terminals
TB1–9 and TB1–10 and install the jumper on terminals TB1–1 and TB1–2.
In the event that the smoke purge function is also enabled, the conditions
described in “Damper Control” are not active. The controller full voltage
bypass will close immediately, accelerating to line frequency speed
regardless of the damper end switch position. Any required interlocks to
prohibit operation once smoke purge has been activated must be connected
to terminals 9 and 10. This may include damper end switch, high static
pressure switch, freeze/firestats or any other device which, when opened,
disables the motor operation even during a smoke purge event. Control
wiring can be used to wire these signals in series so that the interlocks are
active in normal and purge modes of operation. See details on Smoke
Purge Function (Fireman's Override) and Figure 23 (page 65) for
information on wiring external signals to the S-Flex drive with Bypass.

IntroductionThis section provides programming instructions for using Proportional-
Integral-Derivative (PID) control on the S-Flex adjustable speed drive.
PID control provides a method for controlling a process variable using a
closed loop feedback system. The error between the desired setpoint and
feedback process variable provides continuous corrective action to control
the process output. From an application standpoint, the drive output adjusts
the speed of the motor to reduce the error to zero. Closed loop control
eliminates the cycling normally associated with open loop on-off control
methods. PID control aims to regulate the process consistently under
changing conditions at a maximum rate with minimum waste and minimum
cost of operation.
Process variables such as temperature, pressure, and level can be
monitored by the drive as a current or voltage analog feedback signal. The
PID regulator calculates the error between the setpoint and feedback for a
closed loop, then applies an appropriate frequency reference to adjust the
motor speed.
There are three control functions:
1. Proportional (P): The Proportional function determines the
responsiveness of control or how quickly the output reacts to the error.
2. Integral (I): The Integral function determines the reaction based on the
sum of recent errors and its absence may prevent the system from
reaching its target value.
3. Derivative (D): The Derivative function determines the reaction to the
rate at which the error has been changing and is very sensitive to
measurement noise.
The weighted sum of P, I, and D functions is used to correct the process
variable.
By tuning these three functions, the system performance including
responsiveness (time to correct the error), overshoot (overage from the
reference setpoint) and oscillations (cycling between the highest and lowest
point until signal stabilization) can be controlled.

Scaling of PID ParametersScaling of PID parameters is required to suit a customer’s application or
range of the sensor input device providing the feedback signal (or both).
Some examples of PID parameters and their ranges are pressure
(0 to 20 psi), flow (0 to 500 gpm), and temperature (–100 °F to 300 °F).
SPEED REFERENCE LEVEL 1 and 2 parameters must be entered as a
percentage of the analog input range (VIA or VIB) used as the feedback
input signal. The OUTPUT FREQUENCY LEVEL 1 and 2 parameters are
entered in Hz and set as a function of the speed reference (see Figure 31).
Figure 31:Examples of Terminal Setting
SPEED REFERENCE LEVEL parameter:
For a 4–6 V signal, set Speed Reference Level 1 to 40 and Speed
Reference Level 2 to 60. Figure 31 illustrates scaling for a voltage signal of
0-10 V and a current signal of 4–20 mA.
OUTPUT FREQUENCY LEVEL parameter:
For an Output Frequency of 0–60 Hz, set Output Frequency Level 1 to 0
and Output Frequency Level 2 to 60.
PID TuningTuning of the P, I, and D control functions is required to optimize the
process performance based on application needs. There are several
methods for tuning including manual, Ziegler-Nichols, and by using several
software tools available in the market. The PID proportional gain (F362),
Integral gain (F363) and derivative gain (F366) parameters can be adjusted
to allow the PID regulator to be tuned for a specific application.
NOTE: Follow the instructions in Drive Configuration via Integrated or
Graphic Keypad on page 76 to set-up the P, I, and D control functions and
access the parameters for gains adjustment.
In many cases the factory settings for these parameters will be sufficient.
However, if necessary, adjustments should be gradual and independent. If
the system is unstable with the factory settings or the PID reference
(setpoint) is not achieved, use the manual method described below:
•Set the integral gain (F363) to minimum.
•Leave the derivative gain (F366) at 0.
•Vary the load or PID reference setpoint a number of times and observe
the PID regulator response.
•Set the proportional gain (F362) in order to obtain the best compromise
between response time and stability.
•Once stable, if the steady state response varies from the preset value
(setpoint), gradually increase the integral gain (F363), reduce the
proportional gain (F362) in the event of instability (pump applications),
and find a compromise between response time and precision.
•Typically, the derivative gain (F366) is not required, but may permit the
reduction of overshoot and the improvement of response time. This can
make it more difficult to obtain a compromise in terms of stability since
this depends on 3 gains. If F366 is adjusted then the F362 and F363
may require re-adjustment.
Figure 32 on page 75 illustrates the system performance with adjustments
in P, I, and D gains.
Setting PID ControlThe procedure for setting PID control for analog inputs with 0–10 Vdc or
4–20 mA signal is described in this section.
For SFD21, PID control with 4–20 mA current feedback is only possible on
drives without A06, B06, C06, D06 communication options selected.
For SFD212, PID control with 4–20 mA current feedback is only possible on
drives without B06 communication options selected.
Ensure that the factory settings for the enclosed drive and motor parameters
are set. For more information, refer to the Altivar 212 Programming and Operation Guide, S1A53838.
Drive Configuration via Integrated or
Graphic Keypad
With the AFC-OFF-BYP selector switch in the Off position and prior to
applying a run command to the drive, use the keypad to do the following:
Programming by Integrated Keypad:
1. Press the MODE key until AUF displays; then press ENT.
2. Scroll using the UP and DOWN arrow keys until FMOd displays; then
press ENT.
3. Use the UP and DOWN arrow keys to adjust the desired control source.
Procedure is continued on page 77.
Programming by Graphic Keypad:
1. Press the ESC key to display the PROGRAMMING MENU and turn the
Jog dial until FREQUENCY MODE SEL. (FMOd) is highlighted; then
press the Jog dial.
2. Turn the Jog dial to adjust the desired control source, then press the Jog
dial when the desired control source is highlighted.
NOTE: VIA accepts a 0–10 Vdc voltage signal or a 4–20 mA current signal,
VIB accepts a 0–10 Vdc voltage input signal. Refer to the Altivar 212 Installation Guide, S1A53832, for instructions on accessing SW3.
When operating with internal setpoint, the adjusted range is taken as a
percentage value reference and not an actual speed value and may only be
set between the lower speed limit (LL) and upper speed limit (UL). For
example, if the intended reference output frequency is 30 Hz and UL is set
for 60 Hz, the drive requires a reference signal corresponding to 50%. If LL
is set to 30 Hz, the setpoint cannot be set below 50% using this method.
Additional signal manipulation may be required to convert the fundamental
output frequency to rotational speed, pressure, or flow.
4. Press the ENT key to save the selection and to exit the FMOd
parameter.
5. Use the UP and DOWN arrow keys until F--- (extended parameters)
displays; then press the ENT key.
6. Use the UP and DOWN arrows to select the appropriate parameter and
press ENT to modify the parameter.

Description
To enable the run command
signal relay (RA–RC and
RYC–RYA) to include attain
speed signal functionality, set
parameter F137 to 60. The relay
will only energize when the drive
speed reference equals the VIB
signal and a run command is
received.
Parameter F167 determines the
bandwidth around the VIB speed
reference driving the relay output
function.
Control WiringFor analog PID control, wire terminals VIA, VIB, and CC as shown in
Figure 34 (for two-wire loop powered) and in Figure 35 (for separately
powered transducer).
•If the feedback is a 4–20 mA signal, set switch SW3 to the I (current)
position.
•If the feedback is a 0–10 Vdc signal, set switch SW3 to the V (voltage)
position.
Refer to the Altivar 212 Installation Guide, S1A53832, for instructions on
accessing SW3.
Ensure adequate current for the transducer. The 24 Vdc power supply is
current-limitedto 200 mA. A load greater than the limit will cause the
control voltage to dip and may result in erroneous readings from the
transducer.
Failure to follow these instructions can result in injury or equipment
damage.
Figure 35:Separately Powered Transducer
Ground the shield only at one end to prevent large currents from flowing in
the shield. The shield on the ungrounded end may be tied to ground with a
capacitor (for example,10 nF, 100 V or higher) to provide a path for the
higher frequency noise.
Application NotesTo set up the drive for a potentiometer using the drive supplied 10 Vdc
supply or keypad speed reference, refer to the Altivar 212 Installation
Guide, S1A53832, for additional details on power converter terminal block
characteristics. Actual terminal arrangement and termination availability
may vary depending on the communications option selected.
Programming the PID Internal Setpoint
with the Keypad
Set the following parameter: = FNOd to 3. This allows you to program the
internal setpoint with the keypad.
When a run command is issued the default display for the drive will be the is
output frequency.
Press the Up or Down arrow button while watching the gauge that shows
the actual value. Once the actual value reaches the point you want to
maintain, press enter. The setpoint will be shown on the display in a
percentage between Low Speed (LL) and High Speed (UL). For example,
30 is 50%. See “Graphic Keypad Option (D07)” on page 51.
Figure 36:Control Terminals
One internal 10 Vdc supply is accessible through terminal PP, integral to the
power converter. Refer to Figure 36. The power supply is short-circuit and
overload protected and capable of supplying up to 10 mA supply current.
Size the reference potentiometer accordingly within a 1 to10 k range.
Connect the potentiometer as shown in Figure 36.
Set parameters CMOd and FMOd to the values shown in Table 21 to accept
reference from the VIB terminal using the reference potentiometer.
To control the PID reference setpoint from the keypad, press the Loc/Rem
key at any time and provide a speed reference command from the keypad
display using the UP/DOWN arrows.
NOTE: Parameter F732 must be set to 0 to enable Loc/Rem.
Refer to the Altivar 212 Programming and Operation Guide, S1A53838, for
more information.

30072-451-83 S-Flex™ Adjustable Speed Enclosed Drive
Rev. 02, 12/2012Section 6—Maintenance and Support
InspectionPeriodic inspection of the equipment is recommended to maintain the
functionality over the course of its lifetime.
•Inspect the heatsink fans of the controller for blockage and impeded
rotation. To prevent overheating and to allow proper air flow, maintain
the clearances described on page 31.
•Examine the interior and exterior of the controller for moisture, oil, or
other foreign material. Remove all foreign material and clean the
controller.
•Clean the interior and exterior of the controller with a vacuum, do not
use compressed air; it may distribute foreign contaminants to other
surfaces.
•Check the enclosure for damage that might reduce electrical clearances.
•Examine the finish of the enclosure. Touch up the paint if necessary.
Replace any badly oxidized, corroded or damaged enclosure parts.
Maintenance after a Downstream Fault
Has Occurred
Excessive currents during a downstream fault may result in component or
conductor damage. This damage is caused by mechanical distortion,
thermal damage, metal deposits, or smoke from downstream short circuit or
thermal overload currents.
After a downstream fault, locate and correct the cause of the fault. Inspect
all equipment and make any necessary repairs or replacements before
putting the equipment back into service. Make sure all replacement parts
are rated properly and are suitable for the application. If in doubt, consult
your Schneider Electric field sales representative.
After any downstream fault, perform the following maintenance procedures:
1. Examine the enclosure. External evidence of enclosure damage usually
indicates damage within. Extensive damage requires replacement of the
enclosure parts or the equipment entirely.
2. Replace any parts that are damaged or deformed. Pay particular
attention to door hinges and door closing hardware. Inspect the area
around any damaged units (both inside and out) for displaced parts from
the damaged unit.
3. Examine all conductors and tighten all electrical connections to their
proper torque values. Replace any damaged conductors, as well as any
showing signs of arcing damage. Inspect all insulators for cracks or burn
marks and replace any displaying these characteristics.
Circuit Breaker MaintenanceSome S-Flex drives are supplied with circuit breakers. Before performing
any test or maintenance on the circuit breaker, locate the upstream
disconnecting device and lock-out the power feeding the circuit breaker.
Press the push-to-trip button once a year to exercise the circuit breaker. Do
not perform this test under load.
NOTE: The push-to-trip button will not function when the circuit breaker
handle is in the Off (O) position.
Technical SupportWhen troubleshooting the S-Flex enclosed drive, discuss the symptoms of
the reported problems with operating personnel. Ask them to describe the
problem, identify when they first observed the problem, and where the
problem was seen.
Observe the drive system and process. Record the drive motor and
peripheral equipment nameplate data on the Troubleshooting Sheet
provided on page 89. Copy this form as needed.
