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°...

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.
Page 26
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.
Installation Wiring Warning 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.
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.
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.
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 fast- acting fuses rated for 250 VAC or higher. See Table 1 for recommended line fuse sizes.
Installation Speed adjust potentiometer Warning Be sure that the potentiometer tabs do not make contact with the potentiometer enclosure. Grounding the input will cause damage to the drive. Mount the speed adjust potentiometer through a 0.38 in. (10 mm) hole with the hardware provided (Figure 11). Install the circular insulating disk between the panel and the 10K ohm speed adjust potentiometer.
DO NOT connect this equipment with power applied. Failure to heed this directive may result in fire or serious injury. LEESON strongly recommends the installation of a master power switch in the voltage input line. The switch contacts should be rated at a minimum of 200% of motor nameplate current and 250 volts.

Installation Motor connections (all FHP-series controls) Single-phase operation For single-phase operation, connect the motor as shown in Figure 15 (page 28). Ensure that the prewired capacitor and its associated motor coil are connected to terminals U and V as shown. This connection may be internal if using a 2-wire motor.
Installation PREWIRED MOTOR NOTE WINDINGS CAPACITOR This connection may be DO NOT use a internal to the motor (2 wire DIRECTION switch with leads). If not, you must make this set-up. See Figure 16 this connection yourself. on Page 29 for setup using a DIRECTION switch.

Installation Speed Adjust Potentiometer Connections Connect a speed adjust potentiometer to terminals S1, S2 and S3. Make sure the potentiometer is connected so that the motor speed will increase as the wiper (S2) is turned clockwise (CW). See Figure 18 below. TB501 10K OHM SPEED ADJUST...
Installation Voltage Follower Connections Instead of using a speed adjust potentiometer, the drive may be wired to follow a 0 - 5 VDC isolated voltage signal (Figure 19). Connect the signal input (+) to S2 and signal common (-) to S1. Make no connection to S3. A potentiometer can be used to scale the analog input voltage.
Installation Signal and Optional Switch Connections All signal and switch connections are made at TB501. Terminal block orientation and terminal names are identical for all FHP series drives. Use 20 - 24 AWG wire for speed adjust potentiometer and switch connections. ENABLE/DISABLE switch Connect a single-pole, single-throw ENABLE/DISABLE switch between the ENABLE (E2) and COMMON (E1)
Installation DIRECTION (D) switch Connect a single-pole, single-throw DIRECTION switch between the (D) and COMMON (E1) terminals as shown in Figure 21 below. Opening the switch will cause the motor to rotate in the forward direction; closing the switch will reverse motor rotation.
Installation Voltage or Current Follower (PCM models) PCM series drives can be configured to follow a grounded (non-isolated) voltage or current signal. To configure the drive to follow a voltage or current signal, connect the signal leads to the S1 and S2 terminals on TB501. Ensure that the following jumper terminals are properly set: JMP501 Input Range Settings Set jumper in position 1 for 0 - 5 VDC signal input.
Operation Warning Dangerous voltages exist on the drive when it is powered, and up to 60 seconds after power is removed and the motor stops. BE ALERT. High voltages can cause serious or fatal injury. Do not change jumper settings with power applied. Ensure that jumper settings are compatible with the motor being controlled.
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.
Operation 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.
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.
Operation 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.
Operation 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.
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.
Calibration 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.
Calibration 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.
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.
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.
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.
Application Notes Independent adjustable speeds with DIR switch Replace the speed adjust potentiometer with two single- pole multi-position switches, and two or more potentiometers in parallel, with a total parallel resistance of 10K ohms. Figure 25 shows the connection of two independent speed adjust potentiometers that can be mounted at two separate operating stations.
Application Notes RUN/JOG switch Using a RUN/JOG switch is recommended in applications where quick stopping is not needed and frequent jogging is required. Use a single-pole, two-position switch for the RUN/JOG switch, and a single-pole, normally open, momentary operated pushbutton for the JOG pushbutton. Connect the RUN/JOG switch and JOG pushbutton to terminal board TB501 as shown in Figure 26.
Application Notes Single speed potentiometer control of multiple motors Warning The combined current draw of all motors must not exceed the current rating of the drive. The FHP series of controls is capable of operating up to eight 3-phase motors simultaneously. All motors must be of the same type and must control similar loads.
Application Notes Quick Reversing To reverse the direction of motor shaft rotation, install a DPDT center off switch as shown below (Figure 28). The drive will brake the motor before reversing, so there is no need to wait for the motor to coast to a stop before changing direction.
Troubleshooting 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 while troubleshooting. BE ALERT. High voltages can cause serious or fatal injury.
