Chapter 1 Introduction Manual Objectives This manual contains the information necessary to help you perform the following functions on the Bulletin 1395 Discrete Adapter Board option: S Install Hardware S Verify correct Adapter Board input and output wiring S Configure the Adapter control to the Drive and its application This manual is intended for use by personnel familiar with the functions of solid state Drive equipment.
Chapter 1 Introduction Adapter Specifications A listing of board specifications and features is provided in Table 1.A. Any specifications pertaining directly to procedures detailed in this manual, will be stated where necessary in the manual. Table 1.A Discrete Board Specifications 1-2 Type Digital Inputs Use 24V DC or 120V AC, 10mA. NOTE: A separate board and part number is used for each voltage rating. Discrete Outputs Dry relay contacts rated at 0.6 Amps at 125V AC or 2.0 Amps at 30V DC.
Chapter 2 Hardware Description Chapter Objective Chapter 2 contains a general description of the major hardware components of the Discrete Adapter Board. It is not intended to be an all encompassing technical description of each hardware component. This chapter provides basic information to help you: S Identify the discrete board input configuration. S Understand the hardware requirements necessary to interface the Discrete board with peripheral devices.
Chapter 2 Hardware Description Analog Inputs The Discrete card contains four programmable 12-bit analog to digital inputs. These inputs allow a ± 10V DC analog signal to be converted to a ± 2048 digital signal, thus providing 4.88 millivolts per bit resolution. Through programming of associated Scale and Offset parameters the effective range of the converted signal can be extended to ± 32767. The converted analog signal can be used to control any of the 1395 run-time parameters.
Chapter 2 Hardware Description Board Hardware Configuration There are two board configuration options available for the Discrete Adapter Board I/O, 120V AC or 24V DC. The 120V AC Adapter Board configuration has a bank of four two watt resistors located directly above J3. These resistors drop the 120V AC down, and it is then sent through a rectifier and opto-isolator. The 24V DC version also has a bank of smaller resistors.

Chapter 4 Installation Introduction This chapter is a detailed procedure for the proper installation and electrical interconnection of the Bulletin 1395 Discrete 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 Receiving It is your responsibility to thoroughly inspect the equipment before accepting shipment from the freight company.
Chapter 4 Installation If the board will not be installed when it is unpacked, it should be stored 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 Discrete Adapter Board is mounted on the front of the swing out panel (refer to system drawings.

Chapter 5 Start Up Chapter Objectives Terminology This chapter will provide basic procedures that include initial adjustments and configuration of drive control. Procedures you will perform in this chapter include the following: S Establish Configuration Links between Drive and Discrete Board. S Program Discrete Adapter Set-Up Parameters. Parameter – Memory location used to store drive set-up data, or to monitor real time input or output information.
Chapter 5 Start Up Parameter Set Up Description After hard wiring the I/O to the Discrete Adapter board terminals, you must set up parameters in the drive using the Program Terminal to allow for data flow between the Discrete board and the drive. As was shown in Figure 4.4, each terminal has parameters associated with it. Set-Up parameters are used to program the Adapter board functions, and consist of Parameters 550 through 559 for Port A, and 500 through 549 for Port B.
Chapter 5 Start Up S The example shows two analog inputs connected to Parameters 400 and 401. In addition, these parameters are linked to drive Parameters 154 and 157 respectively. When an analog input is applied to analog input # 1, the signal is converted to a digital value and directed to Parameter 401. Since Parameter 401 is linked to Parameter 154 the digital value is directly transferred to Parameter 154 (External Velocity Ref). The same applies to all other analog inputs.
Chapter 5 Start Up Figure 5.
Chapter 5 Start Up Analog Input 1 and Analog Input 2 will be used in detailing the scaling and offset parameters. At Analog Input 1, between TB3 terminals 29 and 30, a potentiometer with a range of ± 10 V DC has been connected. Parameter 401 has been linked to Parameter 154 (Velocity Reference) in the drive, which gives the potentiometer control of the external velocity reference. To calibrate the pot to control 100% base speed in both directions, the scaling parameter must be adjusted.
Chapter 5 Start Up As seen in Figure 5.3, the offset voltage adds the corresponding digital value to the range. In this case, an offset of –5 volts adds a digital value of –1024 to the range. This causes 0 volts on the potentiometer to register as –1024 digital internal to the Drive. This can then be scaled so that 0 volts sends a digital value of –4096 for –100% Torque. Figure 5.
Chapter 5 Start Up Analog Output 1 and Analog Output 2 will be used as examples in detailing the scaling and offset parameters. At Analog Output 1, a meter with a range of 0 to 10 V DC has been connected. Parameter 451 has been linked to Parameter 106, Velocity Feedback. In order for the meter to indicate speed in both directions, the scale and offset parameters must be adjusted (see Figure 5.4). Working in the opposite direction as the analog inputs, apply the scaling factor first.
Chapter 5 Start Up As shown in Figure 5.5, another 0 to 10V DC 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. In this example we assume 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 10V DC output.
Chapter 6 Troubleshooting and Maintenance Introduction This section describes the Discrete adapter board fault diagnostics and how they are processed by the 1395 Drive. All Adapters provide initial fault handling based on conditions 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 6 Troubleshooting and Maintenance Discrete Fault Messages The fault messages available on the Discrete Adapter Board are: S DS-01-DISCRETE OK Indicates no faults are present in the Adapter. S DS-31-ILLEGAL FAULT – Hard Fault Indicates an Internal Adapter error. Replace Discrete Adapter. S DS-54-DP HANDSHAKE – Soft Fault The 1395 Main Computer Board is no longer maintaining communications with the Adapter through Dual-Ported RAM. Ensure proper connection to Microbus interface.
Chapter 7 Periodic Maintenance Preventive Maintenance ATTENTION: Servicing energized industrial control equipment can be hazardous. Severe injury or death can result from electrical shock, burn, or unintended actuation of controlled equipment. Recommended practice is to disconnect and lock out control equipment from power sources, and allow stored energy in capacitors to dissipate, if present.
Chapter 7 Periodic Maintenance ATTENTION: Use of other than factory recommended test equipment for solid state controls may result in damage to the control or test equipment or unintended actuation of the controlled equipment. Static Sensitive Items – While performing maintenance on the 1395 Drive and the Discrete Adapter, special precautions must be observed in handling or touching certain static sensitive components in the cabinet.
