UnoDrive

Characteristics of the UnoDrive servo drives
  • Analog servo drives for DC servo motors
  • Particularly suitable for applications with higher-level controllers (CNC)
  • 19" plug-in module design (3 height units, 8 width units, 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 external RFI-filters
  • Easy wiring, since all connections can be plugged in at the front (BN 6540 to BN 6548) or conventional plug-in module wiring in case of connection from behind using indirect connectors (BN 6550 to BN 6558)
  • 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 double the rated current
  • No noise with switching frequency well above audible range
  • Control supply voltage fed by bus voltage
  • 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
