FC 300 Design Guide
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
defect 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 68
Safe Stop Activated:
Safe Stop has been activated. To resume normal
operation, apply 24 V DC to terminal 37, then
send a reset signal (via Bus, Digital I/O, or by
pressing [RESET]). For correct and safe use of the
Safe Stop function follow the related information
and instructions in the Design Guide
ALARM 70
Illegal FC Configuration:
Actual combination of control board and power
board is illegal.
ALARM 80
Drive Initialised to Default Value:
Parameter settings are initialised to default set-
ting after a manual (three-finger) reset.
ALARM 91
Analogue Input 54 Wrong Settings:
Switch S202 has to be set in position OFF (voltage
input) when a KTY sensor is connected to ana-
logue input terminal 54.
ALARM 250
New Spare Part:
The power or Switch Mode Power Supply has been
exchanged. The frequency converter type code
Troubleshooting
must be restored in the EEPROM. Select the cor-
rect type code in Par 14-23 according to the label
on unit. Remember to select 'Save to EEPROM' to
complete.
ALARM 251
New Type Code:
The Frequency Converter has got a new type
code.
