Adjustable Speed Drives and Drive Systems

ADDvantage-32 DC Drive

DC Drives and Drive Systems

The ADDvantage-32 DC Digital Drive has been designed for quick and easy integration into a system. The drive offers advanced communication, coordination interfaces, and regulation functions.

The drive includes all AC fusing and the motor DC contactor. This saves expensive labor and documentation required to mount and wire these items into a panel or cabinet. Furthermore, it has enough I/O and functionality to handle the most demanding applications without expensive external “master” controllers or other hardware.

Avtron has pre-engineered standard panels and cabinets for all drive sizes. Standard AC and DC power hardware options are offered in cost-effective packages.

ADDvantage-32 DC Drive

The Avtron ADDvantage-32 drive is a three-phase power converter offering advanced features made possible by a powerful 32-bit embedded controller. It provides full-wave digitally-controlled motor armature and field power conversion. Bridges are sized up to 2500 HP and can operate at voltages up to 1000 VDC. For higher horse powers, parallel designs are available.The standard drive has ten digital and ten analog I/O points, two pulse generator/tach/encoder inputs, and an RS 485 multi-drop serial link. Optional plug-in modules are available for I/O expansion, digital coordination, resolver feedback, and ethernet.
  • Pre-programmed software
  • Open architecture
  • Use any programmable logic controller
  • Use any operator interface
  • Superior diagnostics through Avtron’s ADDAPT (TM) software

Large Power Range

The smaller drives are integral, chassis mounted units and the larger drives use separate bridge and control assemblies. Standard single SCR (Silicon Controlled Rectifier) bridge designs are available from 5 to 3000 amps.

Avtron offers both 6 and 12 pulse drive designs and has developed standard modules for parallel SCR firing.

Avtron has also standardized on large drive auxiliary hardware and can offer cost-effective packages which include drives, isolation transformers, AC circuit breakers, DC contactors, and more.

Advanced Communication:

  • IEEE 802.3 (ETHERNET) LAN with Modbus TCP protocol
  • IEEE 802.3 (ETHERNET) LAN with Allen-Bradley ETHERNET/IP protocol
  • IEEE 802.3 (ETHERNET) LAN with GE EGD protocol
  • RS 485 Serial Link with Allen-Bradley DF1 protocol

Avtron System Architecture Communication Protocols

The Avtron concept of a process range drive is based on highly configurable, high performance digital drives with resident capability to perform drive control functions locally utilizing a PLC for operator interface, process I/O, and permissive logic. The PLC is not burdened with time critical and complex drive control functions. It retains the ability to communicate with the drives via a high performance Ethernet.

Based on high speed, open Ethernet communication protocols you get the most flexibility going into the future. Available Avtron Ethernet protocols compatible with popular programmable controller (PLC) hardware include:

  • Ethernet IP – Allen Bradley Control Logix, PLC-5 , SLC
  • Modbus TCP – Modicon, and many others
  • GE EGD – GE 90/70, 90/30

These protocols allow high-speed communication from PLC’s and other external devices to the ADD-32TM drives as well as drive to drive. The benefit is minimized system wiring, enhanced system reliability, while retaining maximum flexibility through the life of the system/product. All Drive related system I/O (except E-Stop) is typically communicated over the Ethernet.

Ethernet also provides the backbone for Avtron’s high performance process and drive diagnostic tool, Performance ViewTM. Large amounts of data taken at high speed usually allow process or drive problems to be diagnosed after only one occurrence. Data is retained for days.

Deterministic Ethernet performance is assured through the use of modern high speed Ethernet switch technology. Full duplex operation of a single device per port assures no data collisions can occur. The ADD-32 supports both 100 base FX fiber optic and 10/100 base TP copper Ethernet media.

The ADD-32 drive product line also supports Devicenet communications to PLC’s and other external devices.

Protection and Diagnostics

ADDvantage-32 includes multi-level protection and diagnostics that make for fast, easy troubleshooting. The front panel of each ADDvantage-32 drive includes four red FAULT LEDs. These light when the corresponding hardware and/or software sensing circuitry reaches a value which can threaten damage to the drive components. Standard protective faults are built-in and include:

  • AC line voltage, phase, and frequency variations
  • DC armature instantaneous overcurrent or open armature
  • DC field current and control loss
  • Control power loss
  • SCR open and short circuit
  • Two user configurable faults

The unit also has extensive power-up self checks including interconnection cable checks and bridge testing.

Pre-Programmed Application Software

The ADDvantage-32 provides access to function blocks, data tables, I/O points, and internal test points. Avtron provides field-proven, pre-programmed software for common applications using plain English and engineering units. Customer personnel can easily enter “configuration and calibration” to customize the standard software for a specific application. Setup is easy because the drive uses engineering units, not cryptic code numbers.

Process Diagnostics

Each drive contains a four-channel high speed Signal Analyzer to help isolate process problems from drive or tuning performance. The drive can be configured to record any 4 internal variables (speed, armature current, etc.) with a configurable trigger. The analyzer can be triggered to save data before and after the next upset. Later, this information can be played back to a personal computer or an “analog” chart recorder.
