Probable Causes / Corrective Actions
12
CONTACTOR
DROPPED
The main contactor(s)
dropped out while driver
is running.
Check the supply circuit of the main
contactors’ coils.
13
NO CONTACTOR
SGN
No contactor picked up
signal is detected in 5
seconds after a speed
signal and direction
signal are detected.
Check the auxiliary contacts of the main
contactors in drive enable (EN) signal
circuit.
14
LOW MOT.
CURRENT
No current can be
delivered to motor coils.
1- Motor wiring may not be connected
properly. Check broken or disconnected
wiring.
2- Check the connection of main
contactors.
15
WRONG
DIRECTION
Lift is not running in
required direction.
Running direction read
from encoder is different
from the direction
inverter commands.
1- U, V, W phases of motor reversed.
Check motor connection.
2- Phase of encoder reversed.
16
UNBALLANCED
CUR.
Unbalanced current at U,
V, W motor outputs.
Over-current at one or
two of motor outputs.
1- Contacts of main contactor may not
conduct. Check the connection of main
contactors.
2- A faulty motor windings.
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.
