ID1 x140 Error during motor
data identification l No motor connected
l Stator resistance too high
l Controller inhibited externally
l Check motor connection
l Check motor data entry
l Enable controller and repeat motor
data identification. The controller
enable must be pending
continuously until the end of the
identification process.
ID2 x141 Error during motor
data identification Motor too small l Check entered motor data
– When setting parameters with
Global Drive Control, use the input
assistant for motor data
l The measurements for the inverter
error characteristic and the stator
resistance are correct (save measured
values in C0003). In the operating
mode U/f characteristic control, the
motor data identification can be
completed.
Controller inhibited externally Enable controller and repeat motor data
identification. The controller enable
must be pending continuously until the
end of the identification process.
LP1 x032 Motor phase
failure A current−carrying motor phase has
failed l Check motor
l Check supply cables
The current limit is set too high Set a lower current limit value under
C0599
This monitoring is not suitable for field
frequencies >480 Hz and synchronous
servo motors Deactivate monitoring with C0597= 3
LU x030 Undervoltage DC bus voltage is smaller than the value
set under C0173 l Check mains voltage
l Check supply module
NMAX x200 Maximum system
speed exceeded
(C0596) Active load too high Check drive dimensioning
Drive is not speed−controlled, torque
excessively limited If required, increase torque limit
Current speed is detected incorrectly Check parameter setting of the
incremental encoder (C0025)
OC1 x011 Overcurrent
(motor current >
2.25−fold rated
controller current,
hardware
monitoring) Short circuit/earth fault l Remove cause of short circuit/earth
fault
l Check motor and cable
l If required, measure the insulation
resistance
Capacitive charging current of the
motor cable too high (especially with
lower powers) Use shorter or low−capacitance motor
cable
Acceleration/deceleration times too
short in proportion to the load (C0012,
C0013, C0105) l Increase the gain (P component) of
the current controller (C0075)
l Reduce integral−action time (integral
action component) of the Imax
controller (C0076)
