Chapter 2–1 2 1302 AC Drive Description Introduction This chapter describes the 1302 Drive and how to identify it based on its model number. This chapter also provides power and enclosure rating information.
2–2 1302 AC Drive Description Drive Description The 1302 Drive is an AC PWM (pulse–width–modulated) inverter that operates on single–or three–phase power as detailed in Figures 2.1 and 2.2. AC input power is applied to the Drive’s input terminals. Voltage transients are suppressed by three metal-oxide-varistor (MOV) suppressors. These suppressors keep any input voltage transients within the maximum voltage rating of the input diode module.

Chapter 3–1 3 1302 Preinstallation General Chapter 3 provides information that you must use when planning a 1302 AC Drive installation. Installation site, wiring and motor application requirements are included in this chapter. ! ! ATTENTION: The following information is merely a guide for proper installation. The National Electrical Code and any other governing regional or local code will overrule this information.
3–2 1302 Preinstallation Site Requirements It is important to properly plan before installing a 1302 Drive to ensure that the Drive’s environment and operating conditions are satisfactory. Note that no devices are to be mounted behind the Drive. This area must be kept clear of all control and power wiring. Read the following recommendations before continuing with the Drive installation.
1302 Preinstallation 3–3 Figure 3.1 Enclosure B Dimensions Figure 3.2 Enclosure C Dimensions Publication 1302-5.
3–4 1302 Preinstallation Cooling Airflow Be sure there is adequate clearance for air ventilation around the Drive. For best air movement, do not mount 1302 Drives directly above each other. Note that no devices are to be mounted behind the Drive. This area must be kept clear of all control and power wiring. See Table 3.A for a listing of the recommended air flow clearances. Table 3.

3–6 1302 Preinstallation Recommended Motor Lead Lengths The following motor lead lengths are recommended to reduce line disturbances and noise. See Figure 3.3. • For applications using one motor, motor lead length should not exceed 76 meters (250 feet). • For applications with multiple motors, total motor lead length should not exceed 76 meters (250 feet). When total lead length exceeds 76 meters (250 feet), nuisance trips can occur, caused by capacitive current flow to ground.

ATTENTION: The 1302 Drive control circuitry includes solid state components.
1302 Preinstallation 3–9 The required external hardwired emergency stop must be either a category 0 or 1 stop, depending on the user’s risk assessment of the associated machinery. In order to fully comply with machinery safety standard EN 60204-1:1992, part 9.2.5.4, at least one of the two stop methods must be a category 0 stop.
3–10 1302 Preinstallation The sum of the maximum full-load sine wave currents of all the motors connected continuously to the Drive must be less than the maximum output current rating under all conditions. Note that each motor requires separate thermal overload protection (for example, a motor relay or a motor thermostat). Publication 1302-5.
Chapter 4–1 4 Installation Introduction This chapter shows how to mount the 1302 Drive and its external components. Also shown are the entry areas for routing wiring in and out of the Drive. Mounting the Drive Attach the drive to the selected flat, vertical surface using the mounting holes provided. Enclosure B and C Drives have four mounting holes. In order to maintain a flat mounting surface and to ensure that bolt tightness is maintained, use washers under the bolt heads. Refer to Figures 3.
4–2 Installation Figure 4.1 Enclosure B Wire Routing Locations Publication 1302-5.
Installation 4–3 Figure 4.2 Enclosure C Wire Routing Locations Publication 1302-5.
4–4 Installation External Component Installation Install the input power and output power components that are located outside of the 1302 enclosure. See Figure 5.1. The following sections describe disconnect, transformer, and AC line branch protection installation Disconnects An input disconnect (for example, a switch or circuit breaker) must be installed in the line before the Drive input terminals in accordance with local, national, and international codes (e.g., NEC/CEC).
Installation 4–5 Input isolation transformers may be needed to help eliminate the following: • • • Damaging line voltage transients. Line noise from the Drive back to the incoming power source. Damaging currents that could develop if a point inside the Drive becomes grounded. Observe the following guidelines when installing an isolation transformer: • • A power disconnecting device must be installed between the power line and the primary of the transformer.
4–6 Installation In multiple motor applications, each motor must have its own user-supplied overload protection. Setting the Analog Input Jumper on the Regulator Board 1302 Drives have an analog speed reference input. This is a jumper-selectable 0 to 10 VDC or 0 to 20 mA input with programmable gain and offset adjustments (parameters F-11 and F-12). Jumper J6 on the Regulator board is set to match the type of incoming analog signal, either voltage or current. See Figures 2.2, 4.3, and 5.3.
Installation 4–7 Motor Preparation Follow these guidelines when preparing to install the motor: • Verify that the motor is the appropriate size to use with the Drive. • Verify that the total motor lead length does not exceed the values given in Chapter 3. • Follow the instructions in the motor instruction manual when installing the motor. • Verify that the motor is properly aligned with the application’s machine to minimize unnecessary motor loading due to shaft misalignment.

Chapter 5–1 5 Drive Wiring Introduction This chapter describes how to wire the 1302 Drive including: input wiring, control and signal wiring, output wiring, and grounding. Input Power Wiring Use the following steps to connect AC input power to the Drive: Step 1. Verify that the AC input power to the Drive corresponds to the drive’s nameplate voltage and frequency. Step 2. Wire the AC input power leads by routing them according to the type of enclosure. Sees Figures 4.1 and 4.2 and Table 3.

Note that these start/stop wiring connections are not to be used in multi-speed preset applications which are discussed in the following section. Figure 5.5 Two–Wire Start/Stop Sample Control Wiring Figure 5.
5–6 Drive Wiring Multi–Speed Preset Wiring Multi-speed preset wiring connects to terminals 6 through 8, and 11. See Figure 5.7. When control type 3 is selected through parameter F-00, remote terminal strip control is enabled with multi-speed presets. This mode of operation changes the functionality of terminals 6 through 8 and may be used in place of 2- and 3-wire start/stop wiring. See Figure 5.8.
Drive Wiring 5–7 Figure 5.
5–8 Drive Wiring ! ATTENTION: The 1302 control circuitry includes solid state components. You must provide an additional hardwired stop circuit to remove AC line power to the Drive in the case of improper operation. Failure to provide a hardwired emergency stop could result in equipment damage, bodily injury or death. When AC input power is removed, there will be a loss of inherent regenerative braking effect and the motor will coast to a stop.

Troubleshooting 9–5 = ELECTRONIC THERMAL OVERLOAD The electronic thermal overload trip level has been exceeded. This fault protects the Drive motor from overheating due to excessive current within a specified period. Note that the fault will not clear until the input line voltage is within the proper range. This may take a few seconds. Possible Cause The current limit setting in FĆ05 is incorrect. Corrective Action If the current limit level is too low relative to load, increase the current level in FĆ05.
9–6 Troubleshooting Use the following procedure to access the error log: Step 1. Enter program mode by pressing the PROGRAM LED turns on. RPM RUN %Load Program Volts Forward Remote Reverse Mode Enter Forward Reverse START STOP RESET Mode Enter key until the Step 2. Press the key until ERR is displayed. The error log precedes parameter F-00 and follows F-49. RPM RUN %Load Program Volts Forward Remote Reverse Mode Enter Forward Reverse START STOP RESET Mode Enter Step 3.
Troubleshooting 9–7 Step 5. Press the RPM RUN %Load Program Volts Forward Remote Reverse STOP RESET key to clear the log. Mode Enter Forward Reverse START STOP RESET The display will return to the active monitor display. Power Module Check If a fault occurs, the Drive displays a fault code and logs the fault code into the error log. If more than one fault occurs, the first fault flashes on the display and the subsequent faults (up to two) are logged in the error log.
