• Possible mechanical problem.
• Acceleration and/or Deceleration times may be too small.
FL 2 DC overvoltage:
• Input voltage too high.
• Deceleration time may be too small.
FL 3 ACS 100 overtemperature:
• Ambient temperature too high.
• Severe overload.
FL 4 Fault current: output earth fault or short circuit
FL 5 Output overload.
