Control Techniques’ Unidrive HS30 high frequency AC drives are designed for applications that require cost effective integration into safety systems and incorporates dual Safe Torque Off and advanced Rotor Flux Control (RFC-A) of open loop induction motors.

Additionally, a single SI interface port for optional industry standard fieldbus, Ethernet, or extended I/O ensures flexible integration with any system.



Conform to safety standards, maximize uptime and reduce costs by integrating directly with safety systems

  • Unidrive HS30 has integrated dual STO inputs for SIL3, PLe conformity, eliminating the need for external safety components

Enhance up-time and system flexibility

  • Flexible system integration and remote diagnostics through optional industrial Ethernet and fieldbus communications SI option modules
  • Flexible I/O that is expandable with SI-I/O option module
  • Unidrive HS30 incorporates an onboard PLC which can execute Machine Control Studio programs for logic and sequencing with real-time tasks - removing the need for additional PLC's Complete IEC 61131-3 programming environment
    • Structured text (ST), function block (FBD), sequential function chart (SFC), ladder diagram (LD), instruction list (IL), and continuous function chart (CFC)

Improve throughput with advanced open-loop motor control algorithms

  • Rotor Flux Control (RFC-A) gives maximum stability and control of induction motors at all powers.
  • S-ramp accel / decel profiling provides smooth speed transitions to minimize “jerk”
  • 180% motor overload suitable for heavy industrial machinery applications

Install and configure quickly and easily

  • Simple fixed LED keypad
  • Useful parameter guide located on the front of the drive
  • Use Unidrive M Connect or an SD card with the AI-Backup Adaptor or AI-Smart-Adaptor to clone and transfer parameter sets
  • DIN rail mounting is supported below 2 hp (1.5 kW)
