Chapter 4 Installation Introduction This chapter is a detailed procedure for the proper installation and electrical interconnection of the Digital Reference Adapter Board. Procedures you will perform in this chapter include: S Verification of proper unpacking and inspection S Verification of proper mounting S Verification of proper wiring NOTE: Normally all installation and configuration requirements have been fulfilled when the product is shipped to the user in an integrated factory controller.
Chapter 4 Installation If the board will not be installed when it is unpacked, you must store it in a clean dry place in the anti-static bag. The storage temperature must be between 0°C (32°F) and +60°C (140°F) with a maximum humidity of 95% non-condensing, to guard against damage to temperature sensitive components. Mounting On 1 – 100 HP 230V and 2 – 200 HP 460V the Digital Reference Adapter Board is mounted on the front of the the swing out panel.

The user will have to reconfigure the drive by replacing the Trim Velocity Reference (parameter 161) with the Tach Velocity (parameter 156). The analog tachometer device generates a DC voltage that is direction sensitive and proportional to speed. The tach output must be connected to an analog input channel on the Discrete Adapter Board.

Chapter 6 Start Up Introduction This chapter will provide you with basic procedures for initial adjustments and configuration of the Drive control. Procedures you will perform in this chapter include the following: S Verification of proper installation and wiring. S Configuration of the Drive Control for Digital Reference Adapter I/O. Terminology Parameter – Memory location used to store Drive set-up data, or to monitor real time input or output information.
Chapter 6 Start Up Each Set-Up parameter associated with a specific input/output is used to define the device connected to that input/output. Often there is more than one Set-Up parameter associated with the I/O. Analog inputs and outputs require two for scaling and offset of the value. Figure 6.1 shows the parameters required for each I/O device used. To use this board with the Bulletin 1395, the Configuration parameters must be linked to the proper parameter in the Drive.
Chapter 6 Start Up Figure 6.
Chapter 6 Start Up Digital Reference Adapter Board Analog Input The Analog Input requires more extensive set-up than the Digital Input. Digital Scale and Offset parameters must be adjusted for each analog input device. Additionally both analog inputs have analog offset and Analog Programmable gain parameters which are digitally adjustable. As with the Digital I/O, each Analog I/O must be linked to a Drive fast parameter in order to be used. An example for Analog Input 1 is shown in Figure 6.2. Figure 6.
Chapter 6 Start Up Analog Inputs – Each analog input has two separate sets of gain and offset adjustments. The first set adjust the gain and offset of the input signal before it reaches the analog to digital converter (A/D). This makes it possible to adjust the input signal so that it uses the full range of the A/D converter. The following steps are general guidelines for adjusting the analog input parameters: 1. The first step is to determine if an analog offset should be applied to the input signal.
Chapter 6 Start Up Figure 6.
Chapter 6 Start Up For Analog Input #2, a 0 to 10 volt potentiometer will be used to adjust the Drives torque reference from –100% to +100%. The Analog In #2 fast parameter (Par 402) , has been linked to the torque reference fast parameter (Par 157). Both the digital scale and offset parameters will need to be adjusted in order to get the entire +/– 100% in the 0 to 10 volt range. As seen in Figure 6.4, the digital offset voltage adds the corresponding value to the input.
Chapter 6 Start Up Figure 6.
Chapter 6 Start Up Analog Outputs – Analog Outputs are similar to analog inputs with the exception that there are no programmable analog gain and offset parameters. Each output has a digital scale and digital offset parameter, along with a specific fast parameter used for linking. Differences occur because of the direction of information flow. The Drive sends a digital value in Drive units which must be converted to an analog signal for use by an external device.
Chapter 6 Start Up Figure 6.5 Example: Analog Output - Speed Indication 0 to 10V range = ± 100% speed 4096 = 100% or 1 per unit Example 1: + 100 B. Speed -4096 to + 4096 SCALE P575 = 0.25 +4096 0 -4096 Scale by 0.25 Offset by 5V adding 1024 Digital Value Meter Voltage % Base Speed 6-10 D Offset P576 = 0.25 +1024 0 -1024 +2048 +1024 0 A -100% B.
Chapter 6 Start Up As was shown previously, another 0 to 10 VDC meter is connected to Digital-To-Analog (D/A) output number 2. In this example, Parameter 452 which feeds the D/A is linked to Drive Parameter 112, Armature Current Feedback. We assume in this example, that Armature Current Feedback will vary between 0% and 200% rated current. This means the Drive digital signal will vary between 0 and 8192 and the D/A signal must vary between 0 and 2048 for a 0 to 10 VDC output.

Chapter 6 Start Up System Power Requirements 6-14 Complete Start-Up Instructions for a 1395 Drive are covered in the basic 1395 Installation manual. You should refer to Chapter 6 of the Installation manual for additional start-up information on connections, power requirements (for example: a 24V DC power supply is required), and process equipment precautions that may be necessary when installing and initializing a Digital Reference Adapter Board.
Chapter 7 Troubleshooting Introduction This chapter describes the Digital Reference Adapter Board fault diagnostics and how they are processed by the 1395 Drive. All Adapters perform initial fault handling based on conditions (noise, heat, voltage etc.) within their environment, and then signal the 1395 which provides further disposition based on system requirements. Faults are divided into three categories as described below: Hard Faults Hard Faults are non-recoverable.
Chapter 7 Troubleshooting Digital Reference Faults The Digital Reference Fault Adapter Board can generate the following fault indications: S GA-01-DIG REF OK Indicates no faults are present in the Adapter. S GA-60-ILLEGAL Mode – Soft Fault Indicates an Internal Adapter error. Remove power and then reapply power. If not solved, replace Digital Reference Adapter. Reapply power, if not solved, reinstall original Adapter, replace Main Control Board, reapply power.

For 1 bit field select type data, the entire 16 bit word is stored in the parameter entry, but only the first bit (bit 0) is used. Parameter Table Storage Whenever power is applied to the drive control, the entire parameter table is copied from EEPROM to RAM (Random Access Memory).
