PRODUCT SPECIFICATIONS TM ABOUT THIS PRODUCT - Bodine’s PACESETTER “NEMA 4” series inverter is designed to provide variable speed control of standard threephase AC induction motors. Adjustable linear acceleration and deceleration are provided, making the drive suitable for soft start applications. The output voltage is sinewave coded PWM operating at 16 kHz, which provides high motor torque, high efficiency, and low noise. The full featured drive is easy to install and operate.
IMPORTANT SAFETY PRECAUTIONS Model 2995 has been evaluated by Underwriters Laboratories for conformance to UL standards 508 and 50 and CSA standard C22.2 No. 14 and bears the UL Recognized Component mark. The AC Drive is a power electronic device. For safety reasons, please read through this operations manual in detail and observe those paragraphs with the safety alert symbol. This is the safety alert symbol. It is used to alert you to potential personal injury hazards.
INSTALLATION This control should only be installed by a qualified person familiar with its operation and associated hazards. The National Electrical Code (NEC), local electrical and safety codes, and when applicable, the Occupational Safety and Health Act (OSHA) should be observed to reduce hazards to personnel and property. Step 1. Examine before installation Check that the model number on the control matches the model number ordered.
Step 2. Choose a Suitable Location The installation site directly impacts the functionality and lifespan of the control. O Avoid areas where surrounding air temperature exceeds 40 C (direct sunlight or near heating equipment or inside a panel without a cooling fan. Avoid locations where the front panel dial and switch may be bumped and accidentally turned on/off or damaged. Avoid environments with corrosive gas. Avoid locations near radioactive matter or flammable material.
CONNECTION CAUTION The PCB inside the inverter enclosure is vulnerable to static electrical charges. Avoid contact with the PCB. Choose an appropriate power source with correct voltage settings for the specification of the AC inverter. Do not use a separate device between control and motor to switch motor ON or OFF during operation. Step 4 – Preliminary Setup Figure 4 - Inside of control, showing location of jumpers and fuses.
In this mode, the motor will produce full rated torque up to 60 Hz. Above 60 Hz, torque will linearly reduce to 50% at 120 Hz. Figure 6 - Graph showing reduction in motor torque at frequencies above 60 Hz. AC LINE VOLTAGE SELECTOR JUMPERS – There are three voltage selector jumpers that must be repositioned if the input line voltage is 230 VAC instead of 115 VAC.
Step 5 – Connect the Motor A cord should be used for the motor connection in order to properly seal the liquid tight fitting. The fitting will accept cord diameters between 0.17” and 0.47” diameter. The length of the cord should be kept short for minimum voltage drop O and only copper wire with 60 C rated insulation should be used. Loosen the nut from the liquid tight fitting and insert the cord through the fitting and into the enclosure.

OPERATION Step 9 – Check System Before Starting WARNING Recheck all connections. Do not open the cover of the inverter when the power is ON to avoid injury caused by electrical shock. Do not attempt to wire circuitry while power is on. CAUTION Do not attempt to make or break connections between motor and inverter when the power supply is turned on, or the inverter may be damaged due to a surge peak. Check that motor is securely mounted. Test motor unloaded first to verify proper setup.
Step 10 – Operate the Inverter TM The PACESETTER “NEMA 4” series inverter is operated using the switches and speed dial on the front panel of the control. See Figure 10 for panel layout. 1) 2) 3) 4) 5) 6) 7) Turn the AC power ON using the toggle switch. The power lamp will illuminate. Turn the direction switch to either the “forward” or “reverse” position. Adjust speed by turning the knob of the speed potentiometer.
MIN: Minimum Speed The MIN trim pot is used to set the minimum output frequency of the drive, which sets the minimum motor speed. The minimum speed is factory set to 10 Hz. Readjust the trim pot as follows: 1. 2. Rotate main speed potentiometer to the minimum speed position (full counterclockwise). Increase setting of MIN trim pot so that motor runs at desired minimum speed.
DEC/B: Deceleration (with 60 Hz or 120 Hz configuration) The DEC/B trim pot sets the time it will take the motor to reach zero speed from an initial full speed setting. The trim pot is factory set to approximately 1.5 seconds. Adjust the trim pot as required for the 3.0 application. SECONDS (60Hz ONLY) 10.0 17.0 1.5 18.5 Application Note: On applications with high inertial loads, the deceleration may automatically increase 0.3 20.0 in time.
2 CL: Current Limit with I t Shutdown The CL trim pot is used to set the maximum motor current that occurs in a stalled condition. The CL trim pot is factory set to approximately 160% of full control rating (3.8 amps). The CL trim pot can be readjusted as required. 2 The current limit also contains an I t trip function. The control will trip according to a predetermined current versus time function. The trip curve is directly related to the CL set point and can be changed with the CL trim 2 pot.
TROUBLESHOOTING WARNING Do not remove the cover of the inverter when the power is ON to avoid injury caused by electrical shock. This control does not require maintenance under normal conditions. If you encounter a problem, read all instructions provided with this control and doublecheck the wiring. If problems persist, contact your source of purchase or a Bodine Authorized Service Center and describe the problem in detail. Performing unauthorized repairs will void the Warranty.
Figure 13 – Location of LED Status Indicators inside the enclosure LED STATUS INDICATORS – Models 2995 contains two LED status indicators on the printed circuit board inside the enclosure. One LED is a green Power On indicator (PWR) that indicates the presence of the bus voltage and the operation of the main control logic power supply. The other LED is a tricolor lamp (ST) that indicates a fault or abnormal condition.
