The frequency converter is an electronic motor controller The operating guide is intended for use by qualified intended for: personnel.

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.

Wait until the motor has the AMA started cooled down. When running correctly between the digital input terminal used above the frequency converter continuous digital input PNP only and terminal Ensure that they are ready for full- 4 4 speed operation.

The connected brake resistor is 3. Brake resistor defect 1. Check that the frequency converter programming BB Connect the ground wire to the nearest grounding terminal in accordance with the 99 grounding instructions provided in chapter 4. When running correctly between the digital input terminal used above the frequency converter continuous digital input PNP only and terminal C Flux Faulty Motor data 3. Failure order confirmation. High voltage Motor 37 Functional isolation. This can be done by using a freewheel diode or, alternatively, a 30 V or 50 V MOV for quicker response time across the coil. Check mains conditions even- Over voltage control can lead to tually use idle current compen- prolonged ramp times and AC- sation devices with chokes Brake can lead to additional warming of the motor. The power consumption of the 1 10 Volt low powered by the 10V supply 10 Volt supply Terminal 50 must not exceed 15 mA. Check Par.
