TrioDrive

Characteristics of the TrioDrive servo drives
  • Analog servo drives for AC servo motors
  • Particularly suitable for applications with higher-level controllers (CNC)
  • Two designs: Compact drives for control cabinet installation, complete with built-in power supply, or 19" plug-in module (chassis available as required)
  • Mains connection to 230 V AC, 3 × 400 V, or 3 × 480 V three-phase mains (each via isolating transformer)
  • Design conforms to EMC requirements (CE marked), compliance with class A and B through RFI-filters (internal with compact drive, external with 19" plug-in module)
  • Easy wiring, since all connections can be plugged in at the front (connection from behind using indirect connectors on request)
  • High performance with compact dimensions thanks to use of surface mounting devices (SMT) and latest power transistors (MOSFETs)
  • Easy installation due to adjustable feedback, speed, offset, and current limit
  • No re-adjustment necessary when the drive is replaced thanks to plug-in customer module with all setting components
  • Easily adapted to non-standard applications with plug-in option modules
  • Rapid acceleration, deceleration and reversing of servo motor by momentary current increase to more than double the rated current
  • No noise with switching frequency well above audible range
  • Control supply voltage fed either by bus voltage or by 24 V DC
  • Safe operation thanks to various protection and monitoring circuits
  • Drive and motor protected by adjustable It current limiter
  • Easy error diagnosis with LEDs for fault, standby, and overload
  • Load and speed monitoring with current and speed monitor outputs
  • Available also adapted to motors of other manufacturers
