Extend the ramp time WARNING 1, 10 Volts low The control card voltage is below 10V from terminal 50. Remove some of the load from terminal 50, as the 10V supply is overloaded. Max. 15mA or minimum 590Ω.
Troubleshooting VLT® HVAC Drive Programming Guide Ensure that Motor data in parameters 1-20 through 1-25 are set correctly. Troubleshooting If an external fan is in use, check in 1-91 Motor External Fan that it is selected. Remove power and check if the motor shaft can be turned. Running AMA in 1-29 Automatic Motor Adaptation (AMA) may tune the frequency converter to the motor more accurately and reduce thermal loading. Check that the motor size matches the frequency converter.
4 4 Troubleshooting VLT® HVAC Drive Programming Guide Verify a proper installation based on EMC requirements. ALARM 18, Start failed The speed has not been able to exceed 1-77 Compressor Start Max Speed [RPM] during start within the allowed time. (set in 1-79 Compressor Start Max Time to Trip). This may be caused by a blocked motor. WARNING 23, Internal fan fault The fan warning function is an extra protective function that checks if the fan is running/mounted.
VLT® HVAC Drive Programming Guide Troubleshooting ALARM 38, Internal fault When an internal fault occurs, a code number defined in the table below is displayed. Troubleshooting Cycle power Check that the option is properly installed Check for loose or missing wiring It may be necessary to contact your Danfoss supplier or service department. Note the code number for further troubleshooting directions. No. 0 Text Serial port cannot be initialised.
4 4 VLT® HVAC Drive Programming Guide Troubleshooting ALARM 50, AMA calibration failed Contact your Danfoss supplier or Danfoss Service Department. ALARM 51, AMA check Unom and Inom The settings for motor voltage, motor current, and motor power are wrong. Check the settings in parameters 1-20 to 1-25. ALARM 52, AMA low Inom The motor current is too low. Check the setting in 4-18 Current Limit. ALARM 53, AMA motor too big The motor is too big for the AMA to operate.
Troubleshooting VLT® HVAC Drive Programming Guide ALARM 80, Drive initialised to default value Parameter settings are initialised to default settings after a manual reset. Reset the unit to clear the alarm. ALARM 92, No flow A no-flow condition has been detected in the system. 22-23 No-Flow Function is set for alarm. Troubleshoot the system and reset the frequency converter after the fault has been cleared.
