Control Techniques’ Unidrive HS70 series high-speed variable frequency AC/Servo drives deliver enhanced control of high speed motors. Additionally, machine throughput is maximized through enhanced single axis control and multi-axis network synchronization. Onboard real-time Ethernet (IEEE 1588 V2), onboard Advanced Motion Controller, and high speed I/O for position capture enables machine builders to create more sophisticated and flexible machines.

The onboard Ethernet is also compatible with EtherNet/IP, Modbus TCP, and Real-Time Motion over Ethernet (RTMoE) for network flexibility.

To meet the needs of any application Unidrive M700 series is available in three variants:

Unidrive HS70: Onboard Ethernet and single STO input
Unidrive HS71: Onboard RS485 to upgrade from Unidrive SP, single STO input
Unidrive HS72: Onboard Ethernet, dual STO inputs

Maximize throughput with superior motor control
- High bandwidth motor control algorithm for open and closed loop induction, synchronous permanent magnet, and servo motors with up to 3,000 Hz current-loop bandwidth and 250 Hz speed loop bandwidth for smooth, efficient motor control
- Flexible speed and position feedback interface supports a wide range of feedback technologies from robust resolvers to high resolution encoders
Optimize system performance with onboard Advanced Motor Controller
- Unidrive HS70 series incorporates an Advanced Motion Controller capable of controlling 1.5 axes. The motion functions are carried out 'on the drive' so that system performance is maximized
Design flexible centralized and decentralized control systems
- MCi modules can be added to execute larger programs for advanced system control capability and can operate as network control masters
- Onboard PLC for logic programs reduce or eliminate the need for external controllers
- Machine Control Studiois an industry standard IEC61131-3 programming environment for efficient system design and configuration used to program the onboard PLC and the co-processor MCi module
  - 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)
- Three System Integration module slots are available to fit additional fieldbus, Ethernet, position feedback, machine control, and expanded I/O options.
Unidrive HS70 and Unidrive HS72 onboard communications
- Integrated dual port Ethernet switch provides simple connectivity using standard connections
- Onboard real-time Ethernet (IEEE 1588 V2) uses RTMoE (Real Time Motion over Ethernet) to provide fast communication and accurate axis synchronization
- Onboard Ethernet supports EtherNet/IP and Modbus TCP communications
Unidrive HS71 onboard communications
- Integrated dual port RS485 provides Modbus RTU connectivity using standard connections
Conform to safety standards, maximize uptime and reduce costs by integrating directly with safety systems
- Unidrive HS70 and Unidrive HS71 has an integrated Safe Torque Off (STO) input and can accommodate an SI-Safety module for safe motion functions; Unidrive HS72 variant has dual Safe Torque Off (2x STO)
