Step 7 - Wire the Control Signal Terminal Block 7.1 7-5 Wiring Function Loss For the unit to run, you must maintain a signal at the Function Loss input (the connection between control terminals 7 and 11). If the Function Loss signal is not present, the unit turns off the power devices and coasts to rest. To restart the unit, you must restore the Function Loss signal, clear any faults, and reassert the Start command.
7-6 Step 7 - Wire the Control Signal Terminal Block 7.3 Wiring the Relay Control Output A single form A relay on the terminal block can be used to indicate the unit is running (default) or has faulted (user option) based on the setup DIP switch setting. Refer to the setup DIP switch description in Chapter 8. Figure 7.6 Relay Control Output Wiring 7.4 17 18 19 20 Connect to external device such as PLC input. N.O.
Step 7 - Wire the Control Signal Terminal Block 7-7 Select the option that is the most suitable for your application. The following sections provide wiring information for each option except the local operator controls. Refer to Section 1.2 for information on the local operator controls. 7.5.1 Wiring the Preset Speed Inputs Control terminals 8, 9, and 10 select seven preset speeds as shown in Table 7.4.
7-8 Step 7 - Wire the Control Signal Terminal Block 7.5.2 Wiring the Speed Reference Signal Potentiometer Control terminal 1 provides a 10 VDC reference for use with the user-supplied 5 kΩ potentiometer. Perform the following procedure to wire the potentiometer as the speed reference (refer to Figure 7.9): 1. Mount the speed reference potentiometer at an appropriate operator-accessible location, less than 300 meters (1000 feet) from the 1329I unit. 2.
Step 7 - Wire the Control Signal Terminal Block 7-9 4 to 20 mA External Speed Reference To use an external 4 to 20 mA signal to set the speed reference, connect the signal leads as shown in Figure 7.11. 4 to 20 mA = minimum speed to maximum speed. Figure 7.11 4 to 20 mA External Speed Reference Wiring 1 2 3 4 5 Shield 4 – 20 mA Speed Reference Input Common (Drive end only) 7.6 Wiring Start / Stop Control Important: The terminal block start function is only active when in terminal block start mode.
7-10 Step 7 - Wire the Control Signal Terminal Block 7.7 Wiring Forward / Reverse Control Important: The terminal block forward/reverse functions are only active when in terminal block start mode. The Forward / Reverse input (the connection between terminals 13 and 14) defines the requested direction of motor rotation. If the input is open, the requested direction is forward. Switching the Forward / Reverse input causes the motor to ramp to rest and then accelerate in the opposite direction.
Chapter 8 Step 8 - Verify the Setup and Adjust Switches if Required The 1329I unit is set up using two rotary switches and a 10-position DIP switch mounted on the printed circuit board as shown in Figure 8.1. Figure 8.1 shows the setting selections and the factory defaults. Normally, no adjustments will be needed to the factory settings. If your application requires adjustment to these settings, refer to the following sections in this chapter.
8-2 Step 8 - Verify the Setup and Adjust Switches if Required Figure 8.1 Rotary Switches and Setup DIP Switch Locations Setup DIP Switch (SW3) OFF ON Max Speed Switch (SW2) Accel/Decel Switch (SW1) DC+ DCDBR PE T/L3 S/L2 R/L1 8.1 Adjusting the Maximum Speed ATTENTION: The user is responsible for ensuring that driven machinery and all drive-train mechanisms are capable of safe operation at maximum speed. Failure to observe this precaution could result in severe bodily injury or loss of life.
Step 8 - Verify the Setup and Adjust Switches if Required 8-3 To set the maximum speed: 1. To increase the maximum speed, turn the maximum speed rotary switch to a higher position number. -orTo decrease the maximum speed, turn the maximum speed rotary switch to a lower position number. 2. Connect the display board ribbon cable and replace the cover. Verify that all four cover screws are in place and tightened. 3. Apply AC input power. 4. Set the operator’s speed reference signal to maximum.
8-4 Step 8 - Verify the Setup and Adjust Switches if Required Note that if the operator speed reference setting is less than the maximum speed value, the acceleration / deceleration ramp time is proportionately less than the acceleration / deceleration setting.
Step 8 - Verify the Setup and Adjust Switches if Required 8.3 8-5 Modifying the Setup Using the Setup DIP Switch The switches in the 10-position setup DIP switch define the characteristics of the 1329I unit as shown in Figure 8.4. The switches are preset at the factory to suit a wide range of applications and normally do not need to be changed. The following sections describe how to modify the setup to suit your specific application, if required.
8-6 Step 8 - Verify the Setup and Adjust Switches if Required The switch at position 1 enables or disables the run on power up function. When this function is enabled, output power is applied to the Motor Section automatically at power up if all run on power up permissive conditions are met. These conditions are: • No faults are active. • The terminal strip function loss input is closed.
Step 8 - Verify the Setup and Adjust Switches if Required 8-7 8.3.4 Auto Restart (Position 4) ATTENTION: When this feature is enabled, the Drive Section will restart automatically after an auto-restartable fault occurs (see Table 8.1). This feature may only be used as outlined in NFPA79, Under Voltage Protection for specialized applications. Equipment damage and/or personal injury or loss of life may result if this feature is used in an inappropriate application.
8-8 Step 8 - Verify the Setup and Adjust Switches if Required 8.3.5 Torque Curve (Position 5) The switch at position 5 selects either a variable torque curve or a constant torque curve. The variable torque selection provides a squared V/Hz curve and 110% electronic thermal overload and 110% current limit for one minute. The constant torque selection provides a linear V/Hz curve and 150% electronic thermal overload and 150% current limit for one minute. Figure 8.
Step 8 - Verify the Setup and Adjust Switches if Required 8-9 8.3.7 Reverse Disable (Position 7) The switch at position 7 enables or disables reverse rotation of the motor. It is factory-set to enable a forward-to-reverse change of motor direction. If this switch is in the ON position, the reverse direction is disabled (locked out). In other words, the motor can run in the forward direction only.
8-10 Step 8 - Verify the Setup and Adjust Switches if Required Figure 8.6 Wiring Minimum Speed 6 7 8 9 10 11 24 Volt DC Min Speed 2 Min Speed 1 Min Speed 0 8.3.9 Start Mode Select (Position 9) Important: This applies only to the local operator control units.
