•The temperature of the heatsink
exceeded a temperature limit.
Check that ambient
temperature does not
exceed drive’s rating.
Check for fan operation
(assuming drive has
fans installed).

20 Motor TOL
Motor timed
overload trip
0
The drive detected an overload
that exceeds the customer’s
defined overload setting.
Check load current
demand. Verify Motor
FLA is programmed to
the correct value.
Verify TOL
characteristic is
correct for the
application.
21 Low Temp
Low
temperature
0
This fault occurs if the
temperature of the heatsink
falls below -10.0 degrees C.
Verify that ambient
temperature is within
the drive’s
specifications;
increase the ambient
temperature if
necessary.
22 Ref Loss
Speed
reference loss
0
The drive detected the analog
input was configured to fault if
the input current went below
the level specified by customer
parameters.
Check physical
connections for
reference signal.
Check that
programming for 4-20
mA signal is correct.
Verify that signal to the
drive is correct.
23 Brk Wire
Broken wire
detection
0
The drive detected that the
potentiometer circuit wiring
opened and generated a fault.
Check wiring for loss of
connection to control
terminals. Check that a
proper-value
potentiometer is
installed.
24 Keypad Loss Keypad loss
0
This fault occurs because of a
problem with the keypad or a
keypad connection. It occurs if
the drive detects that it cannot
read any key presses.
Check the connection
from keypad to control
board. Note that the
keypad is not designed
for remote mounting.
1
This fault occurs because of a
problem with the keypad, a
keypad connection, or the
wrong keypad is being used. It
occurs if the keypad ID for an
Vacon 500x cannot be read.
2
This fault occurs because of a
problem with the keypad or a
keypad connection. It occurs if
the drive detects that it cannot
write to the LCD.
25 Comm Loss
Communicatio
n loss
0
This fault occurs when the drive
is in a serial link control path
and the amount of time since
the last Modbus comm.
exceeds the time set in
parameter 903 (SIO Timer).
Check connections to
the Modbus port.
Adjust value of
parameter 903 (SIO
Timer) as needed.
