Diagnostics & error management
Maloperation of the drive
Motor consumes too
much current
U
min
boost has been selected too high
V/f base frequency has been selected too low Correct setting with
Rated motor data (stator resistance, speed,
current, frequency, voltage) and cos
ϕ
and/
or magnetising inductance is not adapted to
the motor data
Carry out automatic motor parameter
identification with the
controller
command
- or -
Adjust motor parameters manually:
: Motor stator resistance
: Rated motor speed
: Rated motor current
: Rated motor frequency
: Rated motor voltage
: Motor cosine phi
: Motor magnetising inductance
Motor parameter
identification is
aborted with error
LP1
Motor is too small compared to the rated
device power (>1 : 3)
Use device with lower rated power
DC-injection braking (DCB) is active via
terminal
Deactivate
Drive behaviour with
vector control is not
satisfactory
different
Optimise or manually adapt vector control
Sensorless vector control (SLVC)
Carry out automatic motor parameter
identification with the
controller
command
Automatic motor data identification
Torque dip in field
weakening range
or
motor stalling when
being operated in the
field weakening
range
Motor is overloaded
Check motor load
Motor windings are wired incorrectly
Reverse from star connection to delta
connection
V/f base frequency is set too high
Correct setting with
Mains voltage is too low
Increase mains voltage
Parameter changes
are not accepted
Settings according to DIP1, DIP2, P1, P2 and
P3 are active (local mode)
Set DIP1/switch 1 to "OFF" in order that no
parameters of the memory module are
overwritten when the device is started.
