  • Page 5 Safety Information Overview This section states important safety information that must be followed when installing, operating, and servicing the drive. Study this information carefully before working on or with the unit. Failure to follow these instructions may lead to personal injury or death or to damage to the drive, motor, or driven equipment.
  • Page 6 General Precautions Attention Only qualified personnel with the proper skills, instruction, and familiarity with the drive and its applications should install, start up, operate, troubleshoot, and maintain the drive. You must be familiar with the electrical and mechanical components of the system to perform the procedures outlined in this manual.
  • Page 7 Installation Precautions Attention An incorrectly installed or operated drive can result in damage to the equipment it controls. Make certain installation and operating specifications are followed. Attention To provide protection against electrical shock, drives must be mounted in an enclosure meeting at least the requirements of Protective Type IP20 (or NEMA equivalent) according to EN60529 and with top surfaces meeting at least the requirements of IP40 (or NEMA equivalent).
  • Page 8 Attention Drive functionality depends upon the application software installed. Some application software offers automatic restart functions that allow the unit to reset and resume operation after a fault. These functions must not be enabled when hazardous conditions might arise from such action. Certain features may present additional hazardous situations.

  • Page 9: About The Manual

    1.2 Contents The manual provides the instructions and technical information necessary to install and maintain the hardware of Unico’s 1000 family of AC drives. Specifically, the manual pertains to units listed in Table 1-1. The 1140 Variable-Voltage AC Drive is covered separately in publication 1140.40 (111-564).

  • Page 10: Intended Audience

    This manual is not intended to provide in-depth service instructions. For service beyond that described in this manual, please contact Unico or your representative. 1.2.1 Intended Audience The manual is intended for anyone who will be installing and servicing the drive.

  • Page 11: Product Overview

    Product Overview 2.1 Overview This chapter provides an overview of the 1000 family of drives. It gives instructions on unpacking, identifying, storing, and transporting a drive. It also familiarizes the user with the basic features, architecture, and specifications of the drives. 2.2 Unpacking After opening the package, you should verify delivery and inspect the drive before installing, storing, or transporting the unit.

  • Page 12: Verify Delivery

    2.2.2 Verify delivery Check that you received the drive that was ordered as well as any options or accessories. Minimally, you should have received a drive and two manuals (this installation guide and an application guide). Contact your supplier regarding any discrepancies. 2.2.3 Inspect for damage Inspect the drive for any damage that may have occurred during shipment.

  • Page 13: Family Overview

    2.3 Family Overview The 1000 family of AC drives provides digital flux vector control of ordinary three-phase AC motors. The drives combine the latest insulated-gate-bipolar-transistor (IGBT), pulse- width modulation (PWM), and digital signal processor (DSP) technologies with digital- current-regulator (DCR) or digital-space-vector (DSV) control to deliver optimum motor performance, complete programmability, and simplicity of operation.
  • Page 14 Motor-Independent Design The 1000 family drives operate any standard- or inverter-duty AC induction or synchronous motor, making it ideal for retrofits and new applications alike. A unique, proprietary digital current regulator (DCR) tunes the drive continuously in real time, eliminating the usual current-loop tuning process required by conventional drives. Digital space vector (DSV) control can be selected for reduced motor noise and low current ripple.
  • Page 15 Digital Setup, Easy Operation A keypad and liquid crystal display provide a simple interface for setting and viewing operating parameters and diagnostics. All controller settings are made digitally for precision and repeatability. Readouts and fault messages are displayed in readily understandable language.

  • Page 16: Drive Architecture

    2.3.2 Drive Architecture The general function of the drive is to convert a fixed voltage and frequency from an electrical power source into a variable voltage and frequency for controlling an AC motor. The basic architecture of the 1100, 1105, and 1110 drives is shown in Figure 2-2, that of the 1120 drive in Figure 2-3, that of the 1130 and 1230 drives in Figure 2-4, and that of the 1200 in Figure 2-5.

    Mechanical Installation 3.1 Overview Proper mechanical installation of the drive is essential for safe, reliable operation and to simplify electrical wiring and maintenance. This chapter provides information and instructions for determining the best mounting location, selecting an enclosure, planning a layout, and installing the unit. 3.2 Forms Drives are classified into twelve different forms according to their physical size and construction.

  • Page 42: Operating Environment

    3.3.2 Operating Environment The drive should be mounted in an environment that is free from corrosive and volatile vapors, dust and particles, mechanical shock, excessive vibration, water or excessive moisture, and temperature extremes. The required ambient operating conditions are specified in Table 2-3. 3.3.3 Cooling Thermal management techniques may be necessary to keep the drive operating within required temperature specifications, particularly when units are installed within confined...

  • Page 43: Layout Considerations

    3.4 Layout Considerations The following information should be considered when planning a mechanical layout. 3.4.1 Dimensions and Weights The physical dimensions of each drive are provided in Figure 3-1 through Figure 3-5. The approximate weight of each unit is given in Table 3-3 through Table 3-9. Attention Make certain that the mounting surface is strong enough to support the weight of all components to be mounted on it.

  • Page 44: Installation Procedure

    3.5 Installation Procedure Both chassis and enclosed drives can be either foot- or flange-mounted. Figure 3-1 through Figure 3-5 provide the physical dimensions and mechanical layouts of the units. Refer to these figures when planning your layout. Attention Make certain that the mounting surface is secure before mounting the drive. Equipment damage could result from an improperly mounted unit.

  • Page 45: Flush Mounting (Form 22X)

    3.5.2 Flush Mounting (Form 22X) Form 22X drives may be flush mounted to a subpanel inside an enclosure or directly to an enclosure wall. The units require a cutout in the panel or enclosure wall to allow air to vent out the back. Allow clearance behind the cutout for airflow as recommended in Table 3-1.

    Electrical Installation 4.1 Overview This chapter explains the electrical installation of the drive. It covers grounding, input power, motor output, dynamic braking, bus connections, and basic control connections. Since control signals vary from application to application, specific wiring instructions are discussed in the application documentation.

  • Page 64: Insulation Tests

    4.3 Insulation Tests Any site insulation tests must be performed before making electrical connections to the drive. These tests should conform to all applicable national and local codes. A suggested procedure for checking installation insulation is outlined below. Attention Before performing the insulation tests, make certain that the drive is disconnected from the input power (S, T or R, S, T or R1, R2, S1, S2, T1, T2).

  • Page 65: Ground The Drive

    4.4.1 Ground the drive The ground terminals (PE) of the drive should be connected to either a grounding electrode buried in the earth or a suitable plant ground with a solid connection to earth ground. The ground connector should be an electrode conductor or bonding jumper of sufficient capacity.

  • Page 66: Power Source Conditioning

    When using a single-phase input, select a line reactor based upon the input current requirements of the 1110 drive as specified in Table 4-12. You may purchase isolation transformers and line reactors directly from Unico. Contact the factory for more information.
