Conductor Routing and Grounding

WARNING

• Use separate metal conduits for routing the input power, output power, and control circuits.

• A separate ground cable should be run inside the conduit with the input power, output power, and
control circuits.

• DO NOT connect CC to earth ground.

•Use IICC terminal as the return for the V/I input.

• Always ground the unit to prevent electrical shock and to help reduce electrical noise.

• It is the responsibility of the ASD installer/maintenance personnel to provide proper grounding and
branch circuit protection in accordance with the NEC and any applicable local codes.

— The Metal Of Conduit Is Not An Acceptable Ground —

Grounding Capacitor Switch

The ASD is equipped with noise reduction capacitors which are used to reduce the EMI leakage via the
3-phase power-input circuit and for compliance with the Electromagnetic Compatibility Directive
(EMC).

The effective value of the capacitor may be increased, reduced, or removed entirely via the Selector
Switch, Switching Bar, or the Switching Screw — the type used is typeform-specific.

The Grounding Capacitor Switch allows the user to quickly change the value of the capacitance of the
3-phase input circuit without the use of tools.

See the section titled System Grounding on pg. 18 for more on the Grounding Capacitor.

DANGER

Contact With Energized Wiring Will Cause Severe

Injury Or Loss Of Life.

• Turn off, lock out, and tag out all power sources before proceeding to connect the power wiring to
the equipment.

• After ensuring that all power sources are turned off and isolated in accordance with established
lock out/tag out procedures, connect the 3-phase power source wiring of the correct voltage to the
correct input terminals and connect the output terminals to a motor of the correct voltage and type
for the application (refer to the NEC Article 300 – Wiring Methods and Article 310 – Conductors
For General Wiring). Size the branch circuit conductors in accordance with the NEC Table 310.16.

• Ensure that the 3-phase input power is NOT connected to the output of the ASD. This will damage
the ASD and may cause injury to personnel.

• DO NOT connect resistors across terminals PA – PC or PO – PC. This may cause a fire.

• Ensure the correct phase sequence and the desired direction of motor rotation in the Bypass mode
(if applicable).

Protection

• Ensure that primary protection exists for the input wiring to the equipment. This protection must be
able to interrupt the available fault current from the power line. The equipment may or may not be
equipped with an input disconnect (option).

• All cable entry openings must be sealed to reduce the risk of entry by vermin and to allow for
maximum cooling efficiency.

• External dynamic braking resistors must be thermally protected.

• It is the responsibility of the ASD installer/maintenance personnel to setup the Emergency Off
braking system of the ASD. The function of the Emergency Off braking function is to remove
output power from the drive in the event of an emergency. A supplemental braking system may also
be engaged in the event of an emergency. For further information on braking systems, see
parameters F250 and F304.

Note: A supplemental emergency stopping system should be used with the ASD. Emergency

stopping should not be a task of the ASD alone.

• Follow all warnings and precautions and do not exceed equipment ratings.

6 H9 ASD Installation and Operation Manual

System Integration Precautions

WARNING

The following precautions are provided as general guidelines for the setup of the ASD within the

system.

• The TIC ASD is a general-purpose product. It is a system component only and the system design

should take this into consideration. Please contact your TIC Sales Representative for application-

specific information or for training support.

• The TIC ASD is part of a larger system and the safe operation of the ASD will depend upon

observing certain precautions and performing proper system integration.

• Improperly designed or improperly installed system interlocks may render the motor unable to start

or stop on command.

• The failure of external or ancillary components may cause intermittent system operation (i.e., the

system may start the motor without warning).

• A detailed system analysis and job safety analysis should be performed by the systems designer

and/or systems integrator before the installation of the ASD component. Contact your TIC Sales

Representative for options availability and for application-specific system integration information

if required.

Personnel Protection

• Installation, operation, and maintenance shall be performed by Qualified Personnel Only.

• A thorough understanding of the ASD will be required before the installation, operation, or

maintenance of the ASD.

• Rotating machinery and live conductors can be hazardous and shall not come into contact with

personnel. Personnel should be protected from all rotating machinery and electrical hazards at all

times.

• Insulators, machine guards, and electrical safeguards may fail or be defeated by the purposeful or

inadvertent actions of workers. Insulators, machine guards, and electrical safeguards are to be

inspected (and tested where possible) at installation and periodically after installation for potential

hazardous conditions.

• DO NOT allow personnel near rotating machinery. Warning signs to this effect shall be posted at or

near the machinery.

• DO NOT allow personnel near electrical conductors. Contact with electrical conductors can be

fatal. Warning signs to this effect shall be posted at or near the hazard.

• Personal protection equipment shall be provided and used to protect employees from any hazards

inherent to system operation.

H9 ASD Installation and Operation Manual 7

System Setup Requirements

CAUTION

• When using the ASD as an integral part of a larger system, it is the responsibility of the ASD
installer/maintenance personnel to ensure that there is a fail-safe in place (i.e., an arrangement
designed to switch the system to a safe condition if there is a fault or failure).

• Power factor improvement capacitors or surge absorbers MUST NOT be installed on the output of
the ASD.

• Use of the built-in system protective features is highly recommended (i.e., E-Off, Overload
Protection, etc.).

• The operating controls and system status indicators should be clearly readable and positioned
where the operator can see them without obstruction.

• Additional warnings and notifications shall be posted at the equipment installation location as
deemed required by Qualified Personnel.

• System safety features should be employed and designed into the integrated system in a manner
such that system operation, even in the event of system failure, will not cause harm or result in
system damage or injury to personnel (i.e., E-Off, Auto-Restart settings, System Interlocks, etc.).

• The programming setup and system configuration of the ASD may allow it to start the motor
unexpectedly. A familiarity with the Auto-Restart (F301) settings are a requirement to use this
product.

• There may be thermal or physical properties, or ancillary devices integrated into the overall system
that may allow for the ASD to start the motor without warning. Signs to this effect must be posted
at the equipment installation location.

• If a secondary magnetic contactor (MC) or an ASD output disconnect is used between the ASD and
the load, it should be interlocked to halt the ASD before the secondary contact opens. If the output
contactor is used for bypass operation, it must be interlocked such that commercial power is never
applied to the ASD output terminals (U, V, or W).

• When using an ASD output disconnect, the ASD and the motor must be stopped before the
disconnect is either opened or closed. Closing the output disconnect while the 3-phase output of the
ASD is active may result in equipment damage or injury to personnel.

8 H9 ASD Installation and Operation Manual

WARNING

Precautions

• Turn off, lock out, and tag out the main power, the control power, and instrumentation connections
before inspecting or servicing the drive, opening the door of the enclosure, or connecting/
disconnecting the power wiring to the equipment.

• The capacitors of the ASD maintain a residual charge for a period of time after turning the ASD off.
The required time for each ASD typeform is indicated with a cabinet label and a Charge LED
(shown for smaller ASDs in Figure 2 on pg. 16; LED is located on the front panel of larger ASDs).
Wait at least the minimum time indicated on the enclosure-mounted label and ensure that the
Charge LED has gone out before opening the door of the ASD once the ASD power has been
turned off.

• Turn the power on only after attaching (or closing) the front cover and DO NOT remove or open
the front cover of the ASD when the power is on.

• DO NOT attempt to disassemble, modify, or repair the ASD. Call your TIC Sales Representative
for repair information.

• DO NOT place any objects inside of the ASD.

• If the ASD should emit smoke, or an unusual odor or sound, turn the power off immediately.

• The heat sink and other components may become extremely hot to the touch. Allow the unit to cool
before coming in contact with these items.

•The Auto-Restart (F301) programmable functions of the ASD may allow for the system to start or
stop unexpectedly. Signs to this effect are to be clearly posted at the installation location.

• Remove power from the ASD during extended periods of non-use.

• The system should be inspected periodically for damaged or improperly functioning parts,
cleanliness, and to ensure that the connectors are tightened securely.

H9 ASD Installation and Operation Manual 9

Motor Characteristics

Listed below are some variable speed AC motor control concepts with which the user of the
ASD should become familiar.

Motor Autotuning

Motor production methods may cause minor differences in the motor operation. The negative effects of
these differences may be minimized by using the Autotune feature of the ASD. Autotuning is a function
of the ASD that measures several parameters of the connected motor and places these readings in a stored
table. The software uses the information in the table to help optimize the response of the ASD to
application-specific load and operational requirements. The Autotuning function may be enabled for
automatic tuning, configured manually at F400, or disabled.

The measured parameters include the rotor resistance, the stator resistance, the required excitation
inductance, rotational inertia values, and leakage inductance values.

Pulse Width Modulation Operation

The ASD uses sinusoidal Pulse Width Modulation (PWM) control. The output current waveform
generated by the ASD approaches that of a perfect sine wave; however, the output waveform is slightly
distorted. For this reason, the motor may produce more heat, noise, and vibration when operated by an
ASD, rather than directly from commercial power.

Low-Speed Operation

Operating a general-purpose motor at lower speeds may cause a decrease in the cooling ability of the
motor. Reducing the torque requirement of the motor at lower speeds will decrease the generated heat at
lower speeds.

When the motor is to be operated at low speed (less than 50% of full speed) and at the rated torque
continuously, a TIC VF motor (designed for use in conjunction with an ASD) is recommended.

Overload Protection Adjustment

The ASD software monitors the output current of the system and determines when an overload condition
occurs. The overload current level is a percentage of the rating of the motor. This function protects the
motor from overload.

The default setting for the overload detection circuit is set to the maximum rated current of the ASD at the
factory. This setting will have to be adjusted to match the rating of the motor with which the ASD is to be
used. To change the overload reference level, see Motor Overload Protection Level 1 on pg. 182.

Operation Above 60 Hz

A motor produces more noise and vibration when it is operated at frequencies above 60 Hz. Also, when
operating a motor above 60 Hz, the rated limit of the motor or its bearings may be exceeded; this may void
the motor warranty.

Contact the motor manufacturer for additional information before operating the motor above 60 Hz.

10 H9 ASD Installation and Operation Manual

Power Factor Correction

DO NOT connect a power factor correction capacitor or surge absorber to the output of the ASD.

If the ASD is used with a motor that is equipped with a capacitor for power factor correction, remove the
capacitor from the motor.

Connecting either of these devices to the output of the ASD may cause the ASD to malfunction and trip,
or the output device may cause an over-current condition resulting in damage to the device or the ASD.

Light Load Conditions

When a motor is operated under a continuous light load (i.e., at a load of less than 50% of its rated
capacity) or it drives a load which produces a very small amount of inertia, it may become unstable and
produce abnormal vibration or trips because of an over-current condition. In such a case, the carrier
frequency may be lowered to compensate for this undesirable condition (see Program Special 
Carrier Frequency PWM Carrier Frequency).

Note: When operating in the Vector Control mode the carrier frequency should be set to

2.2 kHz or above.

Motor/Load Combinations

When the ASD is used in combination with one of the following motors or loads, it may result in unstable
operation.

• A motor with a rated capacity that exceeds the motor capacity recommended for the ASD.

• An explosion-proof motor.

When using the ASD with an explosion-proof motor or other special motor types, lower the carrier
frequency to stabilize the operation. DO NOT set the carrier frequency below 2.2 kHz if operating the
system in the vector control mode.

Note: When operating in the Vector Control mode the carrier frequency should be set to

2.2 kHz or above.

If the motor being used is coupled to a load that has a large backlash or if coupled to a reciprocating load,
use one of the following procedures to stabilize motor operation.

• Adjust the S-pattern acceleration/deceleration setting,

• If operating in the Vector control mode, adjust the response time, or

•Switch to the Constant Torque control mode.

H9 ASD Installation and Operation Manual 11

Load-Produced Negative Torque

CAUTION

When the ASD is used with a load that produces negative torque (an overhauling load), the over-voltage
or over-current protective functions of the ASD may cause nuisance tripping.

To minimize the undesirable effects of negative torque the dynamic braking system may be used. The
dynamic braking system converts the regenerated energy into heat that is dissipated using a braking
resistor. The braking resistor must be suitably matched to the load. Dynamic braking is very effective in
reducing the DC bus voltage during a momentary over-voltage condition.

If under extreme conditions the dynamic braking system or a component of this system were to fail, the
dynamic braking resistor may experience an extended over-current condition. The DBR circuit was
designed to dissipate excessive amounts of heat and if the extended over-current condition were allowed
to exceed the circuit parameters, this condition could result in a fire hazard.

To combat this condition, the 3-phase input may be connected using contactors that are configured to open
in the event of an extended DBR over-current condition or an internal circuit failure. Using a thermal
sensor and/or overload protection as the 3-phase input contactor drive signal, the contactors will open and
remove the 3-phase input power in the event of an extended DBR over-current or system over-voltage
condition. See Dynamic Braking System Specifications on pg. 266 for more information on using
Dynamic Braking with the H9 ASD.

Motor Braking

The motor may continue to rotate and coast to a stop after being shut off due to the inertia of the load. If an
immediate stop is required, a braking system should be used. The two most common types of motor
braking systems used with the ASD are DC Injection Braking and Dynamic Braking.

For further information on braking systems, see DC Injection Braking on pg. 124 and Dynamic Braking

on pg. 136.

Over-Current Protection

Each ASD model is designed for a specified operating power range. The ASD will incur a trip if the
design specifications are exceeded.

However, the ASD may be operated at 100% of the specified output-current range continuously or at
120% for a limited amount of time as indicated in the section titled Current/Voltage Specifications on pg.

262. Also, the Stall Prevention Level may be adjusted to help with nuisance over-current trips (see F601).

When using the ASD for an application to control a motor that is rated significantly less than the
maximum current rating of the ASD, the over-current limit (Thermal Overload Protection) setting will
have to be changed to match the FLA of the motor. For further information on this parameter, see Motor

Overload Protection Level 1 on pg. 182.

ASD Capacity

The ASD must not be used with a motor that has a larger capacity than the ASD, even if the motor is
operated under a small load. An ASD being used in this way will be susceptible to a high-output peak
current which may result in nuisance tripping.

Do not apply a level of input voltage to an ASD that is beyond that which the ASD is rated. The input
voltage may be stepped down when required with the use of a step-down transformer or some other type
of voltage-reduction system.

Using Vector Control

Using Vector Control enables the system to produce very high torque over the entire operating range
even at extremely low speeds. Vector Control may be used with or without feedback. However, using
feedback increases the speed accuracy for applications requiring precise speed control.

See F015 on pg. 81 for further information on using Vector Control.

H9 ASD Installation and Operation Manual 13

Installation and Connections

CAUTION

The H9 Adjustable Speed Drive may be set up initially by performing a few simple configuration
settings. To operate properly, the ASD must be securely mounted and connected to a power source
(3-phase AC input at the R/L1, S/L2, and T/L3 terminals). The control terminals of the ASD may be
used by connecting the terminals of the Terminal Board to the proper sensors or signal input sources
(see the section titled I/O and Control on pg. 21

System performance may be further enhanced by assigning a function to the output terminals of the
Terminal Board and connecting the terminals to the proper indicators or actuators (LEDs, relays,
contactors, etc.).

Note: The optional ASD interface boards may be used to expand the I/O functionality of the

ASD.

Installation Notes

When a brake-equipped motor is connected to the ASD, it is possible that the brake may not release at
startup because of insufficient voltage. To avoid this, DO NOT connect the brake or the brake contactor
to the output of the ASD.

If an output contactor is used for bypass operation, it must be interlocked such that commercial power is
never applied to the output terminals of the ASD (U/T1, V/T2, and W/T3).

and

Figure 9 on pg. 24).

DO NOT apply commercial power to the ASD output terminals U/T1, V/T2, and W/T3.

If a secondary magnetic contactor (MC) is used between the output of the ASD and the motor, it should
be interlocked such that the ST – CC connection is disconnected before the output contactor is opened.

DO NOT open and then close a secondary magnetic contactor between the ASD and the motor unless
the ASD is off and the motor is not rotating.

Note: Re-application of power via a secondary contact while the ASD is on or while the

motor is still turning may cause ASD damage.

The ASD input voltage should remain within 10% of the specified input voltage range. Input voltages
approaching the upper or lower-limit settings may require that the over-voltage and under-voltage stall
protection level parameters be adjusted. Voltages outside of the permissible tolerance should be
avoided.

The frequency of the input power should be ±2 Hz of the specified input frequency.

DO NOT use an ASD with a motor that has a current rating higher than the rated current of the ASD.

The H9 ASD is designed to operate NEMA B motors. Consult with your TIC Sales Representative
before using the ASD for special applications such as with an explosion-proof motor or applications
with a piston load.

Disconnect the ASD from the motor before megging or applying a bypass voltage to the motor.

Interface problems may occur when an ASD is used in conjunction with some types of process
controllers. Signal isolation may be required to prevent controller and/or ASD malfunction (contact
your TIC Sales Representative or the process controller manufacturer for additional information about
compatibility and signal isolation).

Use caution when setting the output frequency. Over speeding a motor decreases its ability to deliver
torque and may result in damage to the motor and/or the driven equipment.

14 H9 ASD Installation and Operation Manual

Not all H9 ASDs are equipped with internal primary power input fuses (HP dependent). When

Figure 1. Typical Circuit Breaker Configuration.

CAUTION

connecting two or more drives that have no internal fuse to the same power line as shown in Figure 1,
select a circuit-breaking configuration that will ensure that if a short circuit occurs in ASD 1, only
MCCB2 trips, not MCCB1. If it is not feasible to use this configuration, insert a fuse between MCCB2
and ASD 1.

Mounting the ASD

— The following thermal specifications apply to the 230-volt and 460-volt ASDs ONLY —

Install the unit securely in a well ventilated area that is out of direct sunlight.

The process of converting AC to DC, and then back to AC produces heat. During normal ASD
operation, up to 5% of the input energy to the ASD may be dissipated as heat. If installing the ASD in a
cabinet, ensure that there is adequate ventilation.

DO NOT operate the ASD with the enclosure door open.

The ambient operating temperature rating of the 3.0 to 20 HP H9 ASD is 14° to 104° F (-10° to 40° C).

When installing adjacent ASDs horizontally TIC recommends at least 5 cm of space between adjacent
units. However, horizontally mounted ASDs may be installed side-by-side with no space in between the
adjacent units — side-by-side installations require that the top cover be removed from each ASD.

For 150 HP and above ASDs, a minimum of 50 cm of space is required above and below adjacent units
and any obstruction.This space is the recommended minimum space requirement for the ASD and
ensures that adequate ventilation is provided for each unit. More space will provide a better
environment for cooling (see the section titled Enclosure and Conduit Plate Dimensions on pg. 254 for
additional information on mounting space requirements).

Note: Ensure that the ventilation openings are not obstructed.

Power Connection Requirements

Connect the 3-phase input power to the input terminals of the ASD at R/L1, S/L2, and T/L3 (see Figure

3 for the typical electrical connection scheme). Connect the output of the ASD to the motor from the

ASD terminals U/T1, V/T2, and W/T3. The input and output conductors and terminal lugs used shall be
in accordance with the requirements listed in the section titled Current/Voltage Specifications on pg.

262.

If multiple conductors are used in parallel for the input or output power and it is necessary to use
separate conduits, each parallel set shall have its own conduit and not share its conduit with other
parallel sets (i.e., place U1, V1, W1, and a ground wire in one conduit and U2, V2, W2 and a ground
wire in another; refer to the NEC Article 300.20 and Article 310.4). National and local electrical codes
should be referenced if three or more power conductors are run in the same conduit (refer to the NEC
Article 310 adjustment factors).

Note: National and local codes should be referenced when running more than three

conductors in the same conduit.

Install a molded case circuit breaker (MCCB) or fuse between the 3-phase power source and the ASD in
accordance with the fault current setting of the ASD and the NEC Article 430.

The ASD is designed and tested to comply with UL Standard 508C. Modifications to the ASD system
or failure to comply with the short circuit protection requirements outlined in this manual may
disqualify the UL rating. See Table 22 on pg. 268 for typeform-specific short circuit protection
recommendations.

As a minimum, the installation of the ASD shall conform to the NEC Article 110, the Occupational
Safety and Health Administration requirements, and to any other local and regional industry codes
and standards.

Note: In the event that the motor rotates in the wrong direction when powered up, reverse

any two of the three ASD output power leads (U, V, or W) connected to the motor.

Figure 3. H9 ASD/Motor Typical Connection Diagram.

H9 ASD Installation and Operation Manual 17

System Grounding

Proper grounding helps to prevent electrical shock and to reduce electrical noise. The ASD is designed
to be grounded in accordance with Article 250 of the NEC or Section 10/Part One of the Canadian
Electrical Code (CEC).

The grounding conductor shall be sized in accordance with Article 250-122 of the NEC or Part One-
Tab le 6 of the CEC.

— The Metal Of Conduit Is Not An Acceptable Ground —

The input, output, and control lines of the system shall be run in separate metal conduits and each shall
have its own ground conductor.

ASDs produce high-frequency noise — take steps to avoid the negative effects of noise. Listed below
are some examples of measures that will help to combat noise problems.

• DO NOT install the input power and output power wires in the same duct or in parallel with each
other, and do not bind them together.

• DO NOT install the input/output power wires and the wires of the control circuit in the same duct
or in parallel with each other, and do not bind them together.

• Use shielded wires or twisted wires for the control circuits.

• Ensure that the grounding terminals (G/E) of the ASD are securely connected to ground.

• Connect a surge suppressor to every electromagnetic contactor and every relay installed near the
ASD.

• Install noise filters as required.

Grounding Capacitor

The Grounding Capacitor plays a role in minimizing the effects of leakage current through the ASD
system and through ground paths to other systems. Leakage current may cause the improper operation
of earth-leakage current breakers, leakage-current relays, ground relays, fire alarms, and other sensors
— and it may cause superimposed noise on CRT screens.

The Grounding Capacitor Switch allows the user to quickly change the value of the leakage-reduction
capacitance of the 3-phase input circuit. See figures 4, 5, 6, and 7 on pg. 19 for an electrical depiction of
the leakage-reduction functionality and the methods used to change the capacitance value. The method
used is typeform-specific.

If using a 460-volt 5 HP ASD or a 460-volt ASD that is in the range of 7.5 HP to 25 HP, and the U/T1,

V/T2, and W/T3 connections to the motor are 100 meters or more in length, the ASD Carrier
Frequency must be set to 4 kHz or less when activating or deactivating the Grounding Capacitor

Switch. ASD overheating may occur if the Carrier Frequency is set above 4 kHz when activating or

deactivating the Grounding Capacitor Switch.

See pg. 5 for more information on the Grounding Capacitor Switch and pg. 16 for the location.

this terminal may be adjusted for application-specific suitability (see F216 –

F221).

22 H9 ASD Installation and Operation Manual

V/I — The V/I terminal has the dual function of being able to receive an input voltage or current. The
function as a voltage input is to receive a 0 – 10 VDC input signal. The function as a current input is to
receive a 0 – 20 mA input signal. Using either input type, the function is to control the 0.0 – Maximum
Frequency output or the 0.0 to 250% torque output of the ASD. This is an isolated input terminal. This
terminal may be programmed to control the speed or torque of the motor and cannot process both input
types simultaneously. SW301 must be set to V or I to receive a voltage or current, respectively (see

Figure 9 on pg. 24). Terminal scaling and the selection of speed or torque control is accomplished via

parameters F201 – F206. The gain and bias of this terminal may be adjusted for application-specific
suitability (see F470 and F471).

SU+ — Control Power Supply Backup input terminal. This terminal accepts the user-supplied
24 VDC backup power to the control circuits (only). Backup power is used in the event of an open
MCCB or during a momentary loss of the 3-phase input power. Parameter settings, real-time clock
information, and trip history information are retained with the use of the SU+ backup power. See the
section titled Battery Backup on pg. 28 for more information on system backup features.

output may be programmed to provide an indication (open or closed) that any of the functions listed in

Table 8 on pg. 239 has occurred or is active. This function may be used to signal external equipment

(e.g., activate the brake) (see F130). The OUT1 terminal is rated at 2 A/120 VAC and 2 A/30 VDC.

O2A/B (OUT2A/B) — The default function assigned to this terminal is ACC/DEC Complete. This
output may be programmed to provide an indication (open or closed) that any of the functions listed in

Table 8 on pg. 239 has occurred or is active. This function may be used to signal external equipment

(e.g., activate the brake) (see F131). The OUT2 terminal is rated at 2A/120 VAC and 2A/30 VDC.

FP — The default function of this output terminal is to output a series of pulses at a rate that is a
function of the ASD output frequency (50 mA max. at 1.0 kHz to 43.3 kHz). As the output frequency of
the ASD goes up so does the FP output pulse rate. This terminal may be programmed to provide an
output pulse rate that is proportional to the magnitude of the user-selected item from Table 6 on pg. 237.
For further information on this terminal see F676 on pg. 193.

AM — This output terminal produces an output current that is proportional to the output frequency of
the ASD or of the magnitude of the function assigned to this terminal. The available assignments for
this output terminal are listed in Table 6 on pg. 237. For further information on this terminal see F670

on pg. 192.

FM — This output terminal produces an output current or voltage that is proportional to the output
frequency of the ASD or of the magnitude of the function assigned to this terminal. The available
assignments for this output terminal are listed in Table 6 on pg. 237. For further information on this
terminal see F005 on pg. 78. The Voltage/Current output selection is performed at F681.

FLA — One of two normally open contacts that, under user-defined conditions, connect to FLC.

FLB — One of two normally closed contacts that, under user-defined conditions, connect to FLC.

C

FLC — FLC is the common leg of a single-pole double-throw form C relay. The FL relay is the Fault
Relay by default, but may be programmed to any of the selections of Table 8 on pg. 239. For further
information on this terminal see F132 and Figure 8.

Note: The FLA, FLB, and FLC contacts are rated at 2A/120 VAC and 2A/30 VDC.
