ALARM 15, Hardware mismatchA fitted option is not operational with the present controlboard hardware or software.Record the value of the following parameters and contactDanfoss:• Parameter 15-40 FC Type• Parameter 15-41 Power Section• Parameter 15-42 Voltage• Parameter 15-43 Software Version• Parameter 15-45 Actual Typecode String• Parameter 15-49 SW ID Control Card• Parameter 15-50 SW ID Power Card• Parameter 15-60 Option Mounted• Parameter 15-61 Option SW Version (for eachoption slot)ALARM 16, Short circuitThere is short-circuiting in the motor or motor wiring.Troubleshooting• Remove the power to the adjustable frequencydrive and repair the short circuit.WARNING/ALARM 17, Control word timeoutThere is no communication to the adjustable frequencydrive.The warning is only active when parameter 8-04 ControlTimeout Function is not set to [0] Off.If parameter 8-04 Control Timeout Function is set to [2] Stopand [26] Trip, a warning appears and the adjustablefrequency drive ramps down until it trips then displays analarm.Troubleshooting:• Check connections on the serial communicationcable.• Increase parameter 8-03 Control Timeout Time• Check the operation of the communicationequipment.• Verify a proper installation based on EMCrequirements.WARNING/ALARM 22, Hoist mechanical brakeReport value shows what kind it is.0 = The torque reference was not reached before timeout(parameter 2-27 Torque Ramp Up Time).1 = Expected brake feedback not received before timeout(parameter 2-23 Activate Brake Delay, parameter 2-25 BrakeRelease Time).WARNING 23, Internal fan faultThe fan warning function is an extra protective functionthat checks if the fan is running/mounted. The fan warningcan be disabled in parameter 14-53 Fan Monitor ([0]Disabled).Troubleshooting• Check fan resistance.• Check soft charge fuses.WARNING 24, External fan faultThe fan warning function is an extra protective functionthat checks if the fan is running/mounted. The fan warningcan be disabled in parameter 14-53 Fan Monitor ([0]Disabled).Troubleshooting• Check fan resistance.• Check soft charge fuses.WARNING 25, Brake resistor short circuitThe brake resistor is monitored during operation. If a shortcircuit occurs, the brake function is disabled and thewarning appears. The adjustable frequency drive is stilloperational but without the brake function.Troubleshooting• Remove the power to the adjustable frequencydrive and replace the brake resistor (seeparameter 2-15 Brake Check).WARNING/ALARM 26, Brake resistor power limitThe power transmitted to the brake resistor is calculated asa mean value over the last 120 s of run time. Thecalculation is based on the intermediate circuit voltage andthe brake resistance value set in parameter 2-16 AC BrakeMax. Current. The warning is active when the dissipatedbraking energy is higher than 90% of the brake resistancepower. If [2] Trip is selected in parameter 2-13 Brake PowerMonitoring, the adjustable frequency drive trips when thedissipated braking energy reaches 100%.WARNINGIf the brake transistor is short-circuited, there is a risk ofsubstantial power being transmitted to the brakeresistor.WARNING/ALARM 27, Brake chopper faultThis alarm/warning could occur if the brake resistoroverheats. Terminals 104 and 106 are available as brakeresistors Klixon inputs.NOTICE!This signal feedback is used by LHD to monitor thetemperature of the HI inductor. This fault indicates thatKlixon opened on the HI inductor at the active filter side.Status Messages Installation ManualMG37A322 Danfoss A/S © Rev. 04/2015 All rights reserved. 717 7
