warning. Please read these instructions carefully
before performing any of the procedures contained in
this manual.
•
DO NOT INSTALL, REMOVE, OR REWIRE THIS
EQUIPMENT WITH POWER APPLIED. Have a qualified
electrical technician install, adjust and service this
equipment. Follow the National Electrical Code and all
other applicable electrical and safety codes, including the
provisions of the Occupational Safety and Health Act
(OSHA), when installing equipment.
•
Reduce the chance of an electrical fire, shock, or
explosion by using proper grounding, over-current
protection, thermal protection, and enclosure. Follow
sound maintenance procedures.

It is possible for a drive to run at full speed as a result of
a component failure. LEESON strongly recommends the
installation of a master switch in the main power input to stop
the drive in an emergency.
Circuit potentials are at 115 VAC or 230 VAC above earth
ground. Avoid direct contact with the printed circuit board or
with circuit elements to prevent the risk of serious injury or
fatality. Use a non-metallic screwdiver for adjusting the
calibration trimpots. Use approved personal protective
equipment and insulated tools if working on this drive with
power applied.

General Information
The LEESON FHP Series are solid-state, variablefrequency AC motor drives. The FHP utilizes a 115 or 230
VAC, 50/60 Hz, single-phase input, and is factory calibrated
for an output of 0 to 60 Hz. They will operate any 1 HP or
smaller, 115 or 208/230-volt, three-phase-AC-induction,
single-phase permanent split capacitor motor (see page v)
and can be user calibrated for 0 through 120 Hz output.
Although FHP inverters can operate over their full speed
range, most motors will operate with constant torque over a
10:1 speed range, 6 Hz to 60 Hz, and constant horsepower
above 60 Hz. (Inverter-duty motors may operate
satisfactorily over a 20:1 speed range.) Some motors can
be satisfactorily operated at speeds as low as 50 rpm
(speed range 50:1). Below 50 rpm, some motors may
show signs of “stepping” or “cogging”, and may run warmer.
*Although the FHP will allow a minimum of 0 Hz, the actual minimum
frequency is dependent on motor type and load. The motor may need to be
derated for low-frequency (30 Hz and lower) operation. Please consult the
motor manufacturer.
General Information
Many 3-phase inverter manufacturers claim that they can
run single-phase motors effectively. This is normally
accomplished by wiring only 2 phases; however, this
method may cause instabilities due to the lack of feedback
from one of the motor connections. Furthermore, motor
torque will be reduced considerably because the phases
are 120° apart. Although the FHP uses this method of
connection, its fundamental design enables it to operate
efficiently under these conditions.
The FHP series features solid-state reversing with
adjustable acceleration and deceleration. The FHP may
also interface with motor thermal protection through the
enable circuit.

Important Information
 Warning
Caution should be taken when operating fan-cooled
motors at low speeds because their fans may not
move sufficient air to properly cool the motor.
LEESON recommends “inverter-duty” motors when
the speed range is beyond 10:1.
In addition to standard 3-phase induction motors, the
following motor types may be used with FHP Series drives:
• Permanent split capacitor (PSC)
• Shaded pole
• AC synchronous

The following motor types MAY NOT be used:
•
•
•
•
•
Split phase
Capacitor start
Repulsion induction
Series Universal AC/DC
Any motor with starting switch (centrifugal or relay)
and/or separate starting winding.

Installation
175324 Process Control Module (PCM) Mounting
The FHP Series PCM Adder Board accepts a 0 - 5 VDC,
0 - 10 VDC, or 4-20 mA signal and outputs an isolated 0-5
VDC signal without requiring additional panel space. It
mounts directly over the main AC board (bottom board) thus
maintaining the same footprint. Step-by-step information for
mounting the PCM Adder Board to a FHP Series drive is
shown on pages 12 - 14.
Figure 10 (page 11) shows a FHP Series drive with the PCM
adder board installed on the unit and the parts supplied in the
PCM adder kit.

Mounting
 Warning
DO NOT install, rewire, or remove this control with
input power applied. Doing so may cause fire or
serious injury. Make sure that you read and
understand the Safety Warnings before attempting
installation.
NOTE: Horizontal mouting may require derating the
drive. See your LEESON representative for more
information
• It is recommended that the drive be oriented with the
chassis vertical for best heat dissipation. Horizontal
mounting, while acceptable, may require some thermal
derating.
• Six 0.19-inch (5 mm) wide slots accept #8 pan head
screws. Fasten either the large base or narrow flange of
the chassis to the subplate.
• Drive components are sensitive to electrostatic fields.
Avoid direct contact with the circuit board. Hold the drive
by the chassis only.
16
Installation
• Protect the drive from dirt, moisture, and accidental
contact. Provide sufficient room for access to the
terminal block and calibration trimpots.
• Mount the drive away from heat sources. Operate the
drive within the specified ambient operating temperature
range.
• Prevent loose connections by avoiding excessive
vibration of the drive.
• The chassis must be earth grounded. Use a star washer
beneath the head of at least one of the mounting screws
to penetrate the anodized chassis surface and to reach
bare metal.
Installation
Wiring
 Warning
쇵
DO NOT install, rewire, or remove this control with
input power applied. Failure to heed this warning
may result in fire, explosion, or serious injury.
Circuit potentials are at 115 or 230 VAC above ground.
To prevent the risk of injury or fatality, avoid direct
contact with the printed circuit board or with circuit
elements.
Do not disconnect any of the motor leads from the
drive unless power is removed. Opening any one
motor lead may destroy the drive.
• Use 20 – 24 AWG wire for speed adjust potentiometer
wiring. Use 14 – 16 AWG wire for AC line (L1, L2) and
motor (U,V and W) wiring.

18
Installation
Shielding guidelines
 Warning
Under no circumstances should power and logic leads
be bundled together. Induced voltage can cause
unpredictable behavior in any electronic device,
including motor controls.
As a general rule, LEESON recommends shielding of all
conductors.
If it is not practical to shield power conductors, LEESON
recommends shielding all logic-level leads. If shielding the
logic leads is not practical, the user should twist all logic
leads with themselves to minimize induced noise.
It may be necessary to earth ground the shielded cable. If
noise is produced by devices other than the drive, ground
the shield at the drive end. If noise is generated by a device
on the drive, ground the shield at the end away from the
drive. Do not ground both ends of the shield.
Installation
19
If the drive continues to pick up noise after grounding the
shield, it may be necessary to add AC line filtering devices,
or to mount the drive in a less noisy environment.
Logic wires from other input devices, such as motion
controllers and PLL velocity controllers, must be separated
from power lines in the same manner as the logic I/O on
this drive.
Heat sinking
LEESON 1-HP FHP drives (175322, 175323, & 175311)
drives are delivered with a factory-installed heat sink. All
other FHP-series drives have sufficient heat sinking in their
basic configurations. No additional heat sinking is
necessary.
20
Installation
Fusing
FHP series drives require external AC power line fuses.
Connect the external line fuse(s) in series with the AC
voltage input. See Connections on page 22. Use fastacting fuses rated for 250 VAC or higher. See Table 1 for
recommended line fuse sizes.

Ꮨ

Do not connect 230 VAC line input when the drive is
set for 115 VAC input. This will result in severe
damage to the motor and drive, and can lead to
explosion and/or injury. Check jumper settings before
connecting AC power input.
Connect AC power input to L1 and L2 as shown in Figure 13
and 14 (pages 25 & 26), depending on your power needs.
NOTE: Doubler drives are equipped with a voltagedoubling feature, which converts a 115 VAC input to a 230
VAC output, for use with 230V motors. The drive output
current rating remains the same. Use caution when
connecting this output.
• If the input voltage is 115 VAC and the desired output voltage is
230 VAC (voltage doubler mode), set 115V/230V jumper as
shown in Figure 13 (page 25). A line fuse may be added to L2.
• If the input voltage is 230 VAC and the desired output voltage is
230 VAC (no voltage doubler), set 115V/230V jumper as shown
in Figure 14 (page 26). Add a line fuse to L1 and L2. Do not

Operation
Voltage Doubler
 Warning
DO NOT connect 230 VAC line input when drive is set
for 115 VAC input. This will result in severe damage
to the motor and drive, and possible explosion or
severe injury.
Doubler drives are equipped with a unique voltage-doubling
feature, for use when 230 VAC input voltage is not
available. This feature converts a 115 VAC input to a 230
VAC output, for use with 230V motors. The drive output
current rating remains the same.
Refer to Page 24 for connection information. Use extreme
caution when connecting this feature. Incorrect use of this
feature may result in fire and serious injury.
Operation
39
Startup
 Warning
DO NOT change jumper settings with power applied.
Ensure that jumper settings are compatible with the
motor being controlled.
Before applying power, verify that no conductive
material is present on the printed circuit board.
1. Verify that no conductive material is present on the PCB.
2. Verify that the correct voltage is connected to the inputs
before applying power. DO NOT CONNECT 230 VAC
line voltage to a 115 VAC drive. Applying power in this
manner will damage the motor and drive.
3. Set the speed adjust potentiometer to zero (full CCW).
4. Set the DIRECTION switch (if installed) to the desired
direction. If no switch is installed, add or remove a
jumper across the (D) and (E1) terminals, as required.
5. Set the ENABLE/DISABLE switch (if installed) to
ENABLE, or short the ENABLE (E2) and (E1) terminals
on TB501.
6. Apply 115 or 230 VAC, 50/60 Hz, single-phase power to
the drive. The green POWER LED will come on after an
initial delay of 1 - 2 seconds. If the POWER LED does
not light, check the external line fuses to ensure that
they are properly installed and not blown.
40
Operation
7. If you attempt to startup and the yellow TQ LED comes
on, the control has entered torque limit mode. To avoid
this occurrence, you may:
a. increase the torque limit setting*, or
b. lengthen the acceleration time enough to
accomodate the needed starting torque by adjusting
the ACCEL trimpot.
* Do not set the torque limit setting above 150% of the motor’s
nameplate current rating.
To reverse motor direction:
To reverse the direction of motor shaft rotation while the
motor is running, set the DIRECTION switch to the opposite
position. If no DIRECTION switch is installed, open or short
the (D) and (E1) terminals on TB501, as required.
When a new direction is selected, there is no need to open
the enable input. The control will automatically decelerate
the motor to zero speed, reverse direction, and then
accelerate the motor back to the set speed. Acceleration
and deceleration rates are controlled by the ACCEL/DECEL
trimpot settings. If quicker reversing is needed refer to
applications notes section (page 51) for further detail.
Operation
41
Starting and stopping methods
To coast the motor to a stop
Open the ENABLE/DISABLE switch, or remove the jumper
between the ENABLE (E2) and COMMON (E1) terminals of
TB501. Refer to the Application Notes section (page 51) for
instructions on switch installation.
Thermal protection of the motor
The enable input can also act as a motor thermal protection
circuit for motors having a built-in thermal protector. These
thermal protectors are operated only by motor heat and
open the enable circuit when the motor reaches a
temperature capable of causing damage to the motor
winding.
Normally, these thermal protectors automatically close the
circuit when the motor has cooled to a safe temperature. In
operation, when the drive is disabled, or when the motor
overheats, the thermal protector opens the circuit. See
Figure 23 (page 42).

Line starting and line stopping
 Warning
LEESON strongly recommends the installation of a
master power switch in the voltage input line (see
Power and Fuse connections, page 22). The switch
contacts should be rated at a minimum of 200% of
motor nameplate current and 250 volts.
Line starting and line stopping (applying and removing
AC voltage input) is not recommended and should be
used for emergency stopping only. When AC voltage
input is applied to the drive, the motor accelerates to the
speed set by the speed adjust potentiometer. When AC
voltage input is removed, the motor coasts to a stop. To
“jog” a motor, install a normally-open pushbutton switch on
the ENABLE input.
44
Calibration
 Warning
Dangerous voltages exist on the drive when it is
powered, and up to 60 seconds after power is
removed and the motor stops. When possible,
disconnect the voltage input from the drive before
adjusting the trimpots. If the trimpots must be
adjusted with power applied, use insulated tools and
the appropriate personal protection equipment. BE
ALERT. High voltages can cause serious or fatal
injury.
The FHP series has five user-adjustable trimpots. Each
drive is factory calibrated to its maximum current rating.
Re-adjust the calibration trimpot settings to accommodate
lower current motors. See Figure 24 (page 45) for FHP
series trimpot location.
All adjustments increase with clockwise (CW) rotation and
decrease with counter-clockwise (CCW) rotation. Use a
non-metallic screwdriver for calibration. Each trimpot is
identified on the printed circuit board.

Calibration Procedure Setup for 60 Hz Motors:
1. Set the ENABLE switch to the DISABLE (open) position.
If no switch is installed, remove the jumper between the
(E2) and (E1) terminals of TB501.
2. Set the DIRECTION switch to the FWD (open) position.
If no switch is installed, remove the jumper between the
(D) and (E1) terminals of TB501.
3. Set all trimpots except TQ LIMIT and MAX fully
counterclockwise (CCW).
4. Set the TQ LIMIT trimpot to maximum (full CW).
5. Set the speed adjust potentiometer to zero (full CCW).
6. Calibrate the trimmer pots as follows:
MAXIMUM SPEED (MAX SPD)
Rotate the speed adjust potentiometer full CW. Using a
hand-held tachometer or analog frequency meter as a
reference, adjust the MAX trimpot until the desired speed or
frequency is reached.
Calibration
47
TORQUE LIMIT (TQ LIMIT)
 Warning
Although the TQ LIMIT trimpot can be set up to 150%
of the drive nameplate rating, continuous operation
beyond the drive nameplate rating may cause
damage to the motor and/or drive.
1. With no power applied to the drive, connect a (true
RMS) ammeter in series with one of the motor leads.
2. Set the TQ LIMIT trimpot to full CCW.
3. Carefully lock the motor shaft. Ensure that the motor is
firmly mounted.
4. Apply line power. The motor should be stopped.
5. Set the speed adjust potentiometer or reference signal
to maximum speed. The motor should remain stopped.
6. Slowly rotate the TQ LIMIT trimpot clockwise (CW) until
the ammeter reads 120% of maximum motor current.
7. Set the speed adjust potentiometer or reference signal
to zero speed.
8. Remove power from the drive.
9. Remove the lock from the motor shaft.
10. Remove the ammeter in series with the motor lead.
48
Calibration
ACCELERATION (ACCEL)
1. Set the speed adjust potentiometer to zero (full CCW)
and wait for the motor to come to a stop (or minimum
speed).
2. Set the speed adjust potentiometer or reference signal
to maximum speed (full CW) and note the time the
motor takes to accelerate to maximum speed.
3. If the acceleration time differs from the desired time,
adjust the ACCEL trimpot until the desired time is
reached. Rotating the ACCEL trimpot CW increases the
acceleration time.
DECELERATION (DECEL)
1. Set the speed adjust potentiometer to maximum (full
CW) and wait for the motor to come to maximum speed.
2. Set the speed adjust potentiometer to minimum speed
(full CCW) and note the time the motor takes to
decelerate to minimum speed.
3. If the deceleration time differs from the desired time,
adjust the DECEL trimpot until the desired time is
reached. Rotating the DECEL pot CW increases the
deceleration time.
Calibration
49
BOOST
The boost trimpot is used to increase motor torque at low
speeds. The minimum setting is sufficient for most
applications and does not need to be adjusted. If the motor
stalls or runs erratically at very low speeds (below 10 Hz),
the boost trimpot may need adjustment.
1. Run the motor at the lowest continuous frequency/speed
required.
2. Monitor the motor phase current (with a true RMS
meter) while very slowly turning the BOOST trimpot CW
until the motor operates properly, or 100% of the motor
nameplate current is reached.
NOTE: Use the absolute minimum amount of BOOST
necessary to achieve proper motor operation. Improper
use of the BOOST feature may cause motor and/or
drive overheating and failure. If proper motion operation
cannot be achieved with the above procedure, please
contact your LEESON representative for assistance.
50
Calibration
Calibration Procedure Conclusion
1. Set the speed adjust potentiometer to zero (full CCW).
2. Disable the drive by opening the ENABLE/DISABLE
switch or removing the jumper from TB501 (E2) and
(E1) terminals.
3. Remove power to the motor and drive. Calibration is
now complete.

Troubleshooting
Diagnostic LEDs
LEESON FHP Series drives are equipped with diagnostic
LED’s to assist the user in troubleshooting and monitoring
equipment status while in use. Refer to Figure 29 (page
58) for diagnostic LED locations.
POWER LED
The green POWER LED is on when AC line voltage is
applied and the control’s low-voltage power supply is
operational.
FAULT LED
The red FAULT LED turns on when the drive output is
locked out or not ENABLED and any one of the following
fault conditions occur:
1. Overvoltage
• FHP 230AC controls: DC bus exceeds 400 VDC
• FHP 115AC controls: DC bus exceeds 200 VDC
2. Undervoltage
• FHP 230AC controls: DC bus drops below 200 VDC
• FHP 115AC controls: DC bus drops below 100 VDC
3. Instantaneous Overcurrent Trip - Inverter output current has
exceeded safe levels.
Note: The FAULT condition must be reset using the
ENABLE function of the FHP (opening and closing
the ENABLE input).
57
58
Troubleshooting
TQ LIMIT LED
The yellow TQ LIMIT LED is on when the drive output
current exceeds the threshold set by the TQ LIMIT trimpot.
When the TQ LIMIT LED turns on, shut down the motor and
drive by disabling or removing power. Check the motor to
make sure it is not jammed or overloaded. The TQ LIMIT
trimpot may need to be recalibrated. See the Calibration

Optional C510 Capacitor Kit (p/n: 175325)
In some applications, lowering carrier frequency reduces
switching losses and increases bearing life in some motors.
LEESON provides an optional capacitor kit for lowering the
carrier frequency.
The default carrier frequency on FHP controls is 16kHz.
Using one of the capacitors supplied in the kit, the carrier
frequency can be lowered to a range of 12kHz to 4kHz.
Note: Audible noise will increase when the carrier
frequency is lowered.
To lower the carrier freqency on all FHP controls, install one
of the following 2-pin capacitors (C510) on the bottom
board:
