PC3400A Family Hardware Reference Manual

Single axis digital servo amplifier

The PC34xxA Series is a new generation of digital servo amplifiers for controlling Brushless

DC and Brush DC servomotors in position, velocity, or torque (current) modes, feedback

dependent.  Units are available in current ratings of 3, 6, 10 and 20 amps RMS continuous

The PC34xxA Series is a new fourth-generation of digital servo amplifiers for controlling Brushless DC and Brush DC servomotors in position, velocity, or current (torque) modes, feedback dependent.  Units are available in current ratings of 3, 6, 10 and 20 amps RMS continuous. The product series includes four product families: the PC34xxAd, a Digital servo drive, the Intelligent servo drives PC34xxAi and PC34xxAi-001-xI with extended I/O, the high performance DSP model is a PC34xxAc Centennial servo drive. See section 1.2 Model Designations and Specifications for additional detail.  Depending on the model purchased, the PC34xxA product series supports Hall only (Trapezoidal Commutation), Resolver, Comcoder or Hall/Encoder for (Sinusoidal Commutation) or Tach feedback.  Each model of the PC34xxA Series utilizes a space vector control algorithm.  All modes of operation offer a PID loop-tuning feature to optimize the performance of the selected servomotor. Each PC34xxA unit is a power supply, amplifier, controller and heatsink integrated into a single standalone package. The compact size and integrated design of the PC34xxA amplifier simplifies the installation process and reduces down time should the need for replacement arise.  The unit is hardware configured for RS-232 (factory default), RS-422 or RS-485 serial communications with ToolPAC software for configuration, debugging and trouble shooting of the unit.   ToolPAC software allows complete configuration and diagnostics of all features in the unit

Fundamentally, a PC34xxA amplifier is a computer that is dedicated to motion control. Like every other computer it has its own operating system, data storage capabilities, data manipulation capabilities.  The unit also includes a serial interface for data communications.  In addition, its built-in inputs/outputs allow for hard-wired connections for motor feedback and to sensor switches to ensure motion that is in sync with a user’s environment.  All PC34xxA Series servo controllers provide the user with the same basic components, including: 

 • Serial communications port for use with ToolPAC for purposes of trouble shooting and initial drive configuration. 

 • A graphical user interface program, ToolPAC, provides the user with the tools to quickly and easily configure the PC34xxA to a specific motor and application.  ToolPAC provides Wizards for Axis Setup, I/O Configuration, Tuning and is compatible with WIN95/WIN98/NT operating systems. 

 • System software including commands and parameters that allow you to configure the servo controller to your application, to enter and manipulate data, and to tune the performance of the unit to your application. 

 • Methods of control include Position, Velocity, and Current (torque) with the ability to accept Step/Dir, Step+/step- and Encoder quadrature in Following mode whereby you are commanding the servo system in a position following mode.  Master/slave relationships can be developed from the secondary encoder inputs, providing motion output. 

 • Distributed Feedback; A mode of operation where a secondary encoder is used to close the Position loop in an application.  When using Distributed Feedback you will loose the ability to provide Step/Dir, Step+/Step- or Encoder following as the secondary encoder is wired to these HSI inputs. Thus CAM and Master/Slave relationships are likewise not available. 

 • The I/O Configuration Wizard provides the user with the tools to configure Hardware interfaces for High-Speed Encoder inputs, CW, CCW, Home inputs, Brake output that allow you to interface to your machinery/equipment.

The PC34xxAi (Intelligent) Series Controllers accept high level commands directly, eliminating the need for a motion controller and can be operated standalone or networked.  Each unit has the ability to store and execute motion programs. Additional features available are: 

 • Stored program mode refers to a method of control where you create and store motion programs on the servo controller system and execute the programs when required.  Motion programs provide the user with the ability to perform complex, repetitive functions without having to type each individual command line every time you wish to perform the same function.  In this mode you may choose to initiate a program through your communications port or establish a monitor program to allow an input to trigger or begin execution of a particular sequence of commands. 

 • Networked configuration allows for up to 31 axis from a single PC serial port or similar host device.  Multi-axis start and stop, along with on-the-fly speed change, are only a few of the networked features available on these units.  The user must request additional documentation to gain a better understanding of the network requirements.
