WARNING 62
Output Frequency at Maximum Limit:
The output frequency is limited by the value set in
par. 4-19
ALARM 63
Mechanical Brake Low:
The actual motor current has not exceeded the
"release brake" current within the "Start delay"
time window.
WARNING 64
Voltage Limit:
The load and speed combination demands a motor
voltage higher than the actual DC link voltage.
WARNING/ALARM/TRIP 65
Control Card Over Temperature:
Control card over temperature: The cut-out tem-
perature of the control card is 80° C.
WARNING 66
Heatsink Temperature Low:
The heat sink temperature is measured as 0° C.
This could indicate that the temperature sensor is
defective and thus the fan speed is increased to
the maximum in case the power part or control
card is very hot.
ALARM 67
Option Configuration has Changed:
One or more options has either been added or re-
moved since the last power-down.
ALARM 70
Illegal Frequency Configuration:
Actual combination of control board and power
board is illegal.
