Danfoss VLT Midi Drive FC-280P4K0 [127/136] For diagnosis read out the alarm words warning words and extended status words
No. Description Warning Alarm Trip lock Cause
53 AMA big motor X
The power size of the motor is too large for the AMA to
operate.
54 AMA small motor X
The power size of the motor is too small for the AMA to
operate.
55 AMA parameter range X
The parameter values of the motor are outside of the
acceptable range. AMA does not run.
56 AMA interrupt X The AMA is interrupted.
57 AMA timeout X
58 AMA internal X Contact Danfoss.
59 Current limit X X Frequency converter overload.
61 Encoder loss X X
63 Mechanical brake low X
Actual motor current has not exceeded release brake
current within start delay time window.
65 Control card temp X X X
The cutout temperature of the control card has exceeded
the upper limit.
67 Option change X
A new option is detected or a mounted option is
removed.
68 Safe Torque O X X
STO is activated. If STO is in manual restart mode
(default), to resume normal operation, apply 24 V DC to
terminals 37 and 38, and initiate a reset signal (via
eldbus, digital I/O, or [Reset]/[O Reset] key). If STO is in
automatic restart mode, applying 24 V DC to terminals 37
and 38 automatically resumes the frequency converter to
normal operation.
69 Power card temp X X X
The cutout temperature of the power card has exceeded
the upper limit.
80 Drive initialized to default value X All parameter settings are initialized to default settings.
87 Auto DC braking X
Occurs in IT mains when the frequency converter coasts,
and the DC voltage is higher than 830 V for 400 V units
and 425 V for 200 V units. The motor consumes energy
on the DC link. This function can be enabled/disabled in
parameter 0-07 Auto DC Braking.
88 Option detection X X The option is removed successfully.
95 Broken belt X X
120 Position control fault X
188 STO internal fault X
24 V DC supply is connected to only 1 of the 2 STO
terminals (37 and 38), or a failure in STO channels is
detected. Ensure that both terminals are connected to
24 V DC supply, and that the discrepancy between the
signals at the 2 terminals is less than 12 ms. If the fault
still occurs, contact the local Danfoss supplier.

Not while running
Parameter can only be changed when the motor is
stopped.
Err. A wrong password was entered
Occurs when using a wrong password for changing a
password-protected parameter.
