ALARM 15, Hardware mismatch
A tted option is not operational with the present control
board hardware or software.
Record the value of the following parameters and contact
Danfoss:
•
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 each
option slot)
ALARM 16, Short circuit
There is short-circuiting in the motor or motor wiring.
Troubleshooting
•
Remove the power to the adjustable frequency
drive and repair the short circuit.
WARNING/ALARM 17, Control word timeout
There is no communication to the adjustable frequency
drive.
The warning is only active when parameter 8-04 Control
Timeout Function is not set to [0] O.
If parameter 8-04 Control Timeout Function is set to [2] Stop
and [26] Trip, a warning appears and the adjustable
frequency drive ramps down until it trips then displays an
alarm.
Troubleshooting:
•
Check connections on the serial communication
cable.
•
Increase parameter 8-03 Control Timeout Time
•
Check the operation of the communication
equipment.
•
Verify a proper installation based on EMC
requirements.
WARNING/ALARM 22, Hoist mechanical brake
Report 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 Brake
Release Time).
WARNING 23, Internal fan fault
The fan warning function is an extra protective function
that checks if the fan is running/mounted. The fan warning
can be disabled in parameter 14-53 Fan Monitor ([0]
Disabled).
Troubleshooting
•
Check fan resistance.
•
Check soft charge fuses.
WARNING 24, External fan fault
The fan warning function is an extra protective function
that checks if the fan is running/mounted. The fan warning
can be disabled in parameter 14-53 Fan Monitor ([0]
Disabled).
Troubleshooting
•
Check fan resistance.
•
Check soft charge fuses.
WARNING 25, Brake resistor short circuit
The brake resistor is monitored during operation. If a short
circuit occurs, the brake function is disabled and the
warning appears. The adjustable frequency drive is still
operational but without the brake function.
Troubleshooting
•
Remove the power to the adjustable frequency
drive and replace the brake resistor (see
parameter 2-15 Brake Check).
WARNING/ALARM 26, Brake resistor power limit
The power transmitted to the brake resistor is calculated as
a mean value over the last 120 s of run time. The
calculation is based on the intermediate circuit voltage and
the brake resistance value set in parameter 2-16 AC Brake
Max. Current. The warning is active when the dissipated
braking energy is higher than 90% of the brake resistance
power. If [2] Trip is selected in parameter 2-13 Brake Power
Monitoring, the adjustable frequency drive trips when the
dissipated braking energy reaches 100%.
WARNING
If the brake transistor is short-circuited, there is a risk of
substantial power being transmitted to the brake
resistor.
WARNING/ALARM 27, Brake chopper fault
This alarm/warning could occur if the brake resistor
overheats. Terminals 104 and 106 are available as brake
resistors Klixon inputs.
NOTICE!
This signal feedback is used by LHD to monitor the
temperature of the HI inductor. This fault indicates that
Klixon opened on the HI inductor at the active lter side.
