Probable Causes / Corrective Actions
An unexpected situation
occurred 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 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.
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.
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.
The encoder connection
or the encoder data is
incorrect
Check the encoder connection.
The auto tune process
could not be completed
in closed loop mode.
1- Because the motor is not connected the
auto tuning 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 auto tuning is
performed load at motor shaft or with
load balanced for synchronous motors
without.
Mechanical brake
monitoring error
1- The brake release monitoring function
is activated, so check the connection of
brake switches made to PI1 input on
ENCABIT-Plus module.
2- Check the mechanical brake
connection and make sure the brakes are
opened and closed.
