DC Compact

Characteristics of the DC compact servo drives
  • Analog servo drives for DC servo motors
  • Particularly suitable for applications with higher-level controllers (CNC)
  • Compact drives for control cabinet installation, complete with built-in power supply
  • Mains connection to 230 V AC
  • Design conforms to EMC requirements (CE marked), compliance with class A and B through RFI-filters (internal)
  • 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 (MOSFETs)
  • Easy installation due to adjustable feedback, speed, offset, current limit, and I×R compensation
  • 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
