WARNING 59, Current limit:
Contact your Danfoss supplier.
WARNING 61, Encoder loss:
Contact your Danfoss supplier.
WARNING 62, Output Frequency at
Maximum Limit:
The output frequency is higher than 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 combinations demand a
motor voltage higher than the actual DC link
voltage.
WARNING/ALARM/TRIP 65, Control
Card Overtemperature:
Control card overtemperature: The cut-out
temperature of the control card is 176° F [80°
C].
WARNING 66, Heatsink Temperature
Low:
The heatsink temperature is measured at 32°
F [0° C]. This may indicate that the tempera-
ture sensor is defective, and thus the fan
speed is increased to the maximum if the pow-
er 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 nor-
mal 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 rela-
ted information and instructions in the Design
Guide
ALARM 70, Illegal FC Configuration:
Current combination of control board and
power board is illegal.
ALARM 80, Drive Initialized to Default
Value:
Parameter settings are initialized to default
setting after a manual (three-finger) reset.
ALARM 91, Analog Input 54 Wrong Set-
tings:
Switch S202 has to be set in position OFF
(voltage input) when a KTY sensor is connec-
ted to analog input terminal 54.
ALARM 250, New Spare Part:
The power or switch mode power supply has
been exchanged. The adjustable frequency
drive type code must be restored in the EE-
PROM. Select the correct type code in Par
14-23 according to the label on unit. Remem-
ber to select ‘Save to EEPROM’ to complete.
ALARM 251, New Type Code:
The adjustable frequency drive has a new
type code.
