ASDs produce high-frequency noise steps must be taken during installation to avoid the negative effects of noise. Listed below are some examples of measures that will help to combat noise problems. Separate the input and output power conductors of the main circuit. Do not install the input and output wires in the same duct or in parallel with each other, and do not bind them together. Do not install the input or output power conductors of the main circuit 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.

Connecting the ASD

Refer to the section titled Installation Precautions on pg. 4 and the section titled Lead Length Specifications on pg. 21 before attempting to connect the ASD and the motor to electrical power.

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 2002 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 OneTable 6 of the CEC. Note: 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.
L1/R, L2/S, and L3/T are the 3-phase input supply terminals for the ASD. The ASD may be operated from a single-phase supply. When operating using a single-phase supply, use the L1 and L3 terminals. T1/U, T2/V, and T3/W are the output terminals of the ASD that connect to the motor.
G7 ASD Operation Manual 19
An inductor may be connected across terminals PA and PO to provide additional filtering. When not used, a jumper is connected across these terminals (see Figure 18 on pg. 30). Connect the input and output power lines of the ASD as shown in Figure 4. 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 connected to the motor.
Figure 4. ASD/Motor connection diagram.
Connect the 3-phase input power to the input terminals of the ASD at L1/R, L2/S, and L3/T. Connect the output of the ASD to the motor from terminals T1/U, T2/V, and T3/W. The input and output conductors and terminal lugs used shall be in accordance with the requirements listed in the section titled Cable/Terminal Specifications on pg. 195. 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, and W1 in one conduit and U2, V2, and W2 in another) (refer to 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 2002 NEC Article 310 adjustment factors). Note: National and local codes should be referenced when running more than three conductors in the same conduit.

Command and Frequency-Control Override Hierarchy
Table 5 lists the input conditions and the resulting output control source selections for Command and Frequency control Override operation. The G7 ASD reads the command registers of the listed control items from the left to the right. In the table the number 1 indicates that the Override feature is turned on for that control input source; X = Dont are; and 0 = Override Off. The first item to be read that has the Override feature turned on will be used for Command or Frequency control. Table 5. Command and Frequency control hierarchy. 1 Communication Card

See PG Speed Reference Setpoint on pg. 103 for further information on this feature.

Electronic Operator Interface
The G7 Electronic Operator Interface (EOI) is comprised of an LCD display, two LEDs, a rotary encoder, and eight keys. These items are described below and their locations are provided in Figure 19 on pg. 37. The EOI can be mounted remotely from the ASD as described in the section titled EOI Remote Mounting on pg. 190. The dimensional requirements for remote mounting may also be found in this section. Using a screw length that exceeds the specified dimensions may cause deformation of the outer surface of the bezel as shown in Figure 31 on pg. 192 and should be avoided. The interface can operate up to distances of 15 feet from the ASD via the Common Serial (TTL) Port. For distances beyond 15 feet, the RS232/RS485 port is recommended.

EOI Features

LCD Display Displays configuration information, performance data (e.g., motor frequency, bus voltage, torque, etc.), and diagnostic information. Local|Remote Key Toggles the system to and from the Local and Remote modes. The LED is on when the system is in the Local Command mode. The Local mode allows the Command and Frequency control functions to be carried out via the EOI. The Remote mode enables the Command and Frequency control functions to be carried out via the Control Terminal Strip, LED Keypad, RS232/RS485, Communication Card, or Pulse Input. The selection may be made via Program Fundamental Parameters Standard Mode Settings Command Mode. Note: The LED Keypad is under development and is unavailable at the time of the release of this manual.
The availability of the Local mode of operation (Command and Frequency control) may be disabled via Program EOI Option Setups Local/Remote Key. The availability of the Local mode of operation may be reinstated by changing this setting or performing a Reset (see F007). Enter Key Selects a menu item to be changed or accepts and records the changed data of the selected field (same as pressing the Rotary Encoder). Esc Key Returns to the previous level of the menu tree, toggles between the Panel and the Frequency Command screens, or cancels changes made to a field if pressed while still in the reverse video mode (dark background/light text). The 3 functions are menu-specific. Run Key Issues the Run command while in the Local mode. Run Key Status LED Illuminates green while stopped or red while running. Stop Key Issues the Off command (decelerates to Stop at the programmed rate) if pressed once while in the Local mode or initiates an Emergency Off (terminates the ASD output and applies the brake if so configured) if pressed twice quickly from the Local or Remote modes. Up Key Increases the value of the selected parameter or scrolls up the menu listing (continues during press-and-hold). Down Key Decreases the value of the selected parameter or scrolls down the menu listing (continues during press-and-hold).

Program Protection Parameters DC Braking During deceleration this is the frequency at which DC Injection braking will start.

DC Injection Braking

DC Injection Braking is a braking system used with three-phase motors. Unlike conventional brakes, there is no physical contact between the rotating shaft and a stationary brake pad or drum. When braking is required, the drive outputs a DC current that is applied to the windings of the motor to quickly brake the motor. The braking current stops when the time entered in F252 times out. The intensity of the DC current used while braking determines how fast the motor will come to a stop and may be set at F251. The intensity setting is entered as a percentage of the full load current of the ASD. DC Injection Braking is also used to preheat the motor or to keep the rotor from spinning freely when the motor is off by providing a pulsating DC current into the motor at the Carrier Frequency. This feature may be enabled at F254.
