Trip Meaning
Probable Causes / Corrective Actions
17 UP/DOWN
TOGETHER
The up and down direction
signals are activated at the
same time.
Check the connection of direction signals of
ADrive and controller. UP terminal must be used
for up direction signal and DWN terminal must be
used for down direction signal.
18 PAR_2.2 IS WRONG
Parameter 2.2. motor rpm at
nominal speed may be too low
or too high.
For synchronous motors, parameter 2.2 should be
<= 400. For asynchronous motors, parameter 2.2
should be >= 400.
19 LOW SPEED
Motor cannot reach to the
desired speed.
1- Make sure that the mechanical brakes are
released.
2- Check encoder connection
3- In induction motors, rotor-slip may be entered
too low. Check this value.
4- In synchronous motors, motor offset angle may
be wrong or it may be that the auto-tuning was
performed while the encoder direction parameter
setting was wrong. Reverse the encoder direction
setting (2.18) and perform auto-tune again
5- In synchronous motors, number of motor poles
may be set incorrectly (2.19)
20 INTERNAL ERROR 2
The reference speed is higher
than V3 speed.
1- Ensure that V0, V1 and V2 speeds are not
higher than V3.
2- The Acceleration end soften S2 may be too
high.
21 INTERNAL ERROR 3
An unexpected situation
occured at motor outputs
1- Ensure that the main contactors are not picked
up and dropped out during the drive.
2- Check the connection of ENABLE signal.
3- Check whether there is a looseness in motor
and contactor connection.
4- Ensure that the components such as brake coil,
contactor coil that may create electrical noise
have appropriate filtering.
22 Fout > Flim
Drive output frequency is
higher than the limit value set
in parameter 11.5 in an
disallowed area (at lower or
upper shaft limit)
1- Ensure that the parameter 11.4 PIN input
function on ADrive is not assigned to “Shaft limit
control” unnecessarily.
2- PIN input function is assigned to “Shaft limit
control” and shaft lower/upper additional limit
switch has interrupted the drive.
3- Check that the parameter 11.5 is not set too
low.
23 ENCABIT TIME OUT
The communication between
ADrive and ENCABIT-Plus
module cannot established
1- Ensure that the ENCABIT-Plus module is
mounted on ADrive.
2- Check the connection between ADrive and
ENCABIT-Plus module.
24 ENCODER ERROR
The encoder connection or the
encoder data is incorrect
Check the encoder connection.
25 AUTO TUNE
ERROR
The autotune process could
not be completed in closed
loop mode.
1- Because the motor is not connected the
autotuning may not have been completed.
2- Check the encoder connection
3- The motor contactors may not pick up. Ensure
that the motor contactors are picked up when the
inverter starts running.
4- Ensure that the autotuning is performed load at
motor shaft or with load balanced for
synchronous motors without.
