Servo Drive Technology

TrioDrive A

Characteristics of the TrioDrive A servo drives
  • Analog servo drives for AC servo motors
  • Particularly suitable for applications with higher-level controllers (CNC)
  • Compact drives for control cabinet installation, very compact design
  • Complete with built-in power supply for direct connection to 230 V AC
  • Design conforms to EMC requirements due to integrated line filters (CE marked), usable in First and Second Environment according to IEC 61800-3
  • Easy wiring, since all connections can be plugged in at the front
  • High performance with compact dimensions thanks to use of surface mounting devices (SMT) and latest power transistors (IGBTs)
  • Easy installation due to adjustable gain, speed, and offset
  • 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 double the rated current
  • No noise with switching frequency well above audible range or low power dissipation with reduced switching frequency (selectable)
  • 24 V control supply voltage fed externally to retain position information in an emergency stop
  • Safe operation thanks to various protection and monitoring circuits
  • Drive and motor protected by adjustable It current limiter
  • Frequent switching off and on possible thanks to rapid discharge of the DC-bus voltage in case of mains switch off (function can be deactivated)
  • Easy error diagnosis with LEDs for ready, overload, fault, standby, and shunt
  • Load and speed monitoring with current and speed monitor outputs
  • Available also adapted to motors of other manufacturers
