ID1 x140 Errors during
motor data
identification
z No motor connected
z Stator resistance too high
z Controller inhibited externally
z Check motor connection
z Check motor data entry
z Enable controller and repeat motor
data identification. The controller
enable must be pending continuously
until the end of the identification
process.
ID2 x141 Errors during
motor data
identification
Motor too small z Check entered motor data

error characteristic and the stator
resistance are correct (save measured
values in C0003). In the operating
mode V/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
z Check motor
z 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
fixed under C0173
z Check mains voltage
z 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 in correctly 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 z Remove cause for short circuit/earth
fault
z Check motor and cable
z If required, measure the insulation
resistance
Capacitive charging current of the
motor cable too high (especially with
lower power)
Use shorter or low-capacitance motor
cable
Too short acceleration or deceleration
times in proportion to the load (C0012,
C0013, C0105)
z Increase the gain (P component) of
the current controller (C0075)
z Reduce the integral-action time
(integral action component) of the
Imax controller (C0076)
