WARNING 66, Heatsink Temperature Low:
The heatsink temperature is measured at 32°F [0°C]. This may indicate
that the temperature sensor is defective, and thus the fan speed is in-
creased to the maximum if the power part or control card is very hot.
ALARM 67, Option Configuration has Changed:
One or more options has either been added or removed 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 69, Pwr.card temp:
Power card overtemperature.
ALARM 70, Illegal FC Configuration:
Current combination of control board and power board is illegal.
Warning 73, Safe Stop Auto Restart:
Safe Stopped, the drive may autostart when safe stop is removed
WARNING 77, Reduced power mode:
This warning indicates that the drive is operating in reduced power mode
(i.e., less than the allowed number of inverter sections). This warning will
be generated on power cycle when the drive is set to run with fewer
inverters and will remain on.
ALARM 79, Illegal PS config:
Current sensor connector at power card not installed or the scaling card
is the incorrect part number or is not installed
ALARM 80, Drive Initialized to Default Value:
Parameter settings are initialized to default setting after a manual (three-
finger) reset.
WARNING 81, CSIV corrupt:
CSIV file has syntax errors.
WARNING 82, CSIV parameter error:
CSIV parameter error
WARNING 85, Dang fail PB:
Profibus/Profisafe Error
ALARM 91, Analog Input 54 Wrong Settings:
Switch S202 has to be set in position OFF (voltage input) when a KTY
sensor is connected to analog input terminal 54.
ALARM 243, Brake IGBT:
F enclosure equivalent to fault 27 in D and E enclosures. Report value
indicates source of the alarm (from left):
0-3 Inverter
4-7 Rectifier
ALARM 244, Heatsink temp:
F enclosure equivalent to fault 29 in D and E enclosures. Report value
indicates source of the alarm (from left):
0-3 Inverter
4-7 Rectifier
ALARM 245, Heatsink sensor:
F enclosure equivalent to fault 39 in D and E enclosures. Report value
indicates source of the alarm (from left):
0-3 Inverter
4-7 Rectifier
ALARM 246, Pwr. card supply:
F enclosure equivalent to fault 46 in D and E enclosures. Report value
indicates source of the alarm (from left):
0-3 Inverter
4-7 Rectifier
ALARM 247, Pwr. card temp:
F enclosure equivalent to fault 69 in D and E enclosures. Report value
indicates source of the alarm (from left):
0-3 Inverter
4-7 Rectifier
ALARM 248, Illegal PS config:
F enclosure equivalent to fault 79 in D and E enclosures. Report value
indicates source of the alarm (from left):
0-3 Inverter
4-7 Rectifier
ALARM 250, New Spare Part:
The power or switch mode power supply has been exchanged. The ad-
justable frequency drive type code must be restored in the EEPROM.
Select the correct 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 adjustable frequency drive has a new type code.
