AKD-C/N Safety

AKD-C

  • Safe electrical separation, as per EN 61800-5-1, between the power input and the signal electronics
  • Soft-start, overvoltage detection, short-circuit protection, phase-failure monitoring.
  • Ready to Operate (relay contact)
  • Safe Torque Off (STO), SIL 2 according to IEC 62061 "PL d" according to ISO 13849-1

AKD-N

  • Safe electrical separation, as per EN 61800-5-1, between the DC power input / motor connections and the signal electronics.
  • Overvoltage detection, short-circuit protection.
  • Safe Torque Off (STO), SIL 2 according to IEC 62061 "PL d" according to ISO 13849-1
  • Temperature monitoring of the servo amplifier and motor.
