Drive Control Systems

Drive control systems are at the very heart of what we do at Crawford Technical Services. From July 2011 to July 2012 we have successfully installed and supported over 200 drives that total over 5,000HP. These drive systems range from open loop vector pump drives to servo drives with encoder feedback and networked Ethernet communications. In addition, we have worked with many brands of drives (listed below) and have experienced drive professionals to work with our clients to both support existing infrastructure and to develop new systems.
