The frequency converter is an electronic motor controller The operating guide is intended for use by qualified intended for: personnel. A power drive system consists of the attention to the safety instructions and general warnings.

Safety note: To avoid electrical shock hazard- even after the power is disconnected- wait at least as follows before doing service on the frequency converter: V: 0. Warning Alarm Trip lock. The operation values shown on the display give detailed information about the status of the drive and the connected peripherals. These values are accessible also when warning and alarm messages are shown. RS or Profibus. Alarm with Trip lock An Alarm with Trip lock can be reset only after a complete mains off Display dark.

Capacitor Reforming Procedure to condition the capacitors for the ideal Drives more than a year The capacitors will fully get drained out during its ideal time due to the internal ESR of the capacitor If we suddenly supply it with full voltage, there will be a high inrush charging current which leads to the breakdown of the capacitor In a normal scenario and for all the new drives, there is no need to do any additional precautions for Capacitor. But Capacitor conditioning can be carried out if the Drive was kept idle for more than a year The capacitors need to be slowly charged with controlled DC source and then only they can be used normally If DC source is not available then we can use series lamps for soft charge the drives with a small rating of MCB. Also, check for bad bearings. This is caused by motor overload conditions. This alarm doesn't show up when the drive is starting. Reduce the load: min res hm. Alarm Hardware mismatch Non-compatible option installed Alarm 2: Live zero error An input ma or v control signal is missing Alarm Std bus timeout The connection to the serial communication port has been lost Alarm 50 - AMA failure AMA procedure could not be carried out Alarm Drive initialized All parameters in the drive have been reset to their default values. Ensure that the drive is sized and programmed correctly. Check application for problems.

The mains supply is not stable or overloaded. This also applies to products already on order provided that such alterations can be made without subsequential changes being necessary in specifications already agreed. The USB ground connection is not galvanically isolated from protective earth. When supplied from an isolated mains source IT regulations. It may be necessary to contact the Danfoss supplier or The signal from the IGBT thermal sensor is not available on service department. To obtain an EMC-compliant installation, follow the instructions provided in chapter 4. For maximum wire sizes, see chapter 8. Search inside document. With automatic restart enabled, the motor The frequency converter is too cold to operate. The determined resistance of 5. Replace remedied, the frequency converter can be reset. Output I Analog output
