Table 25: Warnings and Alarms Code List (continued)
Number Description Warning Alarm Trip lock Cause
52 AMA low I
nom
– X – Motor current is too low. Check the settings.
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 ac-
ceptable range. AMA does not run.
56 AMA interrupt – X – The AMA is interrupted.
57 AMA timeout – X – –
58 AMA internal – X – Contact the local supplier.
59 Current limit X X – The drive is overloaded.
60 External interlock – X – –
61 Encoder loss X X – –
62 Output Freq limit X X – Refer to the chapter List of Warnings and Alarms.
63 Mechanical brake low – X – Actual motor current has not exceeded release brake
current within start delay time window.
64 Voltage limit X – – The load and speed combination demands a motor volt-
age higher than the actual DC-link voltage.
65 Control card temp X X X The cutout temperature of the control card is 80 °C (176
°F).
67 Option module configu-
ration has changed
– X – One or more options have either been added or re-
moved since the last power-down.
69 Power card temp X X X –
70 Illegal FC config – X X –
80 Drive initialized to de-
fault value
– X – All parameter settings are initialized to default settings.
87 Auto DC brake X – – Occurs in IT mains when the drive coasts and the DC
voltage is higher than 830 V. Energy on DC-link is con-
sumed by the motor. This function can be enabled/dis-
abled in parameter 0-07 Auto DC Braking.
88 Option detection – X – A change in the option layout is detected. Parameter
14-89 Option Detection is set to [0] Frozen configuration
and the option layout has been changed.
• To apply the change, enable option layout changes in
parameter 14-89 Option Detection.
• Alternatively, restore the correct option configuration.
