Servo Drive Technology

TrioDrive D/xS
Characteristics of the TrioDrive D/xS servo drives
  • Digital servo drives for AC servo motors and direct drives (torque motors, linear motors)
  • Compact drives for control cabinet installation, complete with built-in power supply for direct connection to 230 V~ AC (wide-range input)
  • Integrated safety system, wear-free, two-channel (category 1 to 4 according to EN 954-1); PL e according to ISO 13849-1 and SIL 3 according to IEC 61800-2 in preparation
  • Design conforms to EMC requirements (CE marked; class A standard, class B through accessories)
  • Switching frequency 8 or 16 kHz selectable for optimum dynamic characteristics and small motor power loss
  • High dynamics and control quality through signal processor for digital control of current and speed (controller cycle time 62.5 µs)
  • Position control loop (16-bit microcontroller, cycle time 1 ms) integrated, setting the target positions via communication interfaces (standard) or positioning control with 500 blocks (option)
  • Rapid acceleration, deceleration, and reversing of the motor by momentary current increase to three times the rated current
  • High processor power for fast axis control and communication
  • Extensive technology functions, positioning control as an option
  • 8 digital inputs, 4 digital outputs, additionally 2 analog inputs and 2 analog outputs (partly optional)
  • Communication via fieldbus interface according to DRIVECOM profile 22 or serial port, RS 232C (standard)
  • Easy wiring, since all connections can be plugged in at the front and at the top
  • Certification according to UL (CSA on request)
  • Comfortable commissioning and diagnosis using a personal computer
  • Function blocks for the development of customized application programs and easy integration in automation systems available
Varianten:
