1379–2819 Internal fault. Contact the Danfoss supplier or Danfoss service department.
1792 Hardware reset of digital signal processor.
1793 Motor-derived parameters not transferred correctly to the digital signal processor.
1794 Power data not transferred correctly at power-up to the digital signal processor.
1795 The digital signal processor has received too many unknown SPI telegrams. The AC drive also uses this fault code if
the MCO does not power up correctly. This situation can occur due to poor EMC protection or improper grounding.
1796 RAM copy error.
2561 Replace the control card.
2820 LCP stack overflow.
2821 Serial port overflow.
2822 USB port overflow.
3072–5122 Parameter value is outside its limits.
5123 Option in slot A: Hardware incompatible with the control board hardware.
5124 Option in slot B: Hardware incompatible with the control board hardware.
5125 Option in slot C0: Hardware incompatible with the control board hardware.
5126 Option in slot C1: Hardware incompatible with the control board hardware.
