22 Ref Loss
Speed reference
loss
0
The drive detected the ana-
log input was configured to
fault if the input current
went below the level speci-
fied by customer parame-
ters.
Check physical connections for ref-
erence signal. Check that pro-
gramming for 4–20 mA signal is
correct. Verify that signal to the
drive is correct.
23 Brk Wire
Broken wire de-
tection
0
The drive detected that the
potentiometer circuit wir-
ing opened and generated
a fault.
Check wiring for loss of connection
to control terminals. Check that a
proper-value potentiometer is in-
stalled.
24
Keypad
Loss
Keypad loss
0
This fault occurs because
of a problem with the key-
pad or a keypad connec-
tion. It occurs if the drive
detects that it cannot read
any key presses.
Check the connection from keypad
to control board. Note that the key-
pad is not designed for remote
mounting.
1
This fault occurs because
of a problem with the key-
pad, a keypad connection,
or the wrong keypad is be-
ing used. It occurs if the
keypad ID for an Vacon 50X
cannot be read.
2
This fault occurs because
of a problem with the key-
pad or a keypad connec-
tion. It occurs if the drive
detects that it cannot write
to the LCD.
25
Comm
Loss
Communication
loss
0
This fault occurs when the
drive is in a serial link con-
trol 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.
26
Regen
Time
Regen timeout 0
This fault occurs if the
drive takes more time to
decelerate to a stop than is
allowed. The timeout is de-
termined by the longest
deceleration ramp time
(Decel1 or Decel2) plus the
Regen Timeout parameter.
Reduce the amount of regenerative
energy or increase the Regen time-
out parameter.
27
Pwr
Bridge
Power bridge
fault
0, 1, 2
The drive detected a failure
in the output power devic-
es.
Check for failed input power device.
28 Drive TOL
Drive timed over-
load
0
The drive sensed an over-
load that exceeded the
drive rating.
Check that load conditions do not
exceed the drive’s rating (120% for
60 seconds from nameplate cur-
rent rating for normal duty and
150% or rated current for 60 sec-
onds heavy duty).
29 Stuck Key Stuck key error 0
This fault occurs if a key
press is detected upon
power-up. This would oc-
cur because of a defective
keypad or because some-
one was holding down a
key when powering-up the
drive.
Check for stuck keypad and repair
or replace. Consult VACON.
