ID1: Motor data identification error During the identification of the motor
parameters, an error has occurred.
Possible causes:
• Interrupted motor cable.
• Switched-off power section during the
identification.
• Implausible start parameter settings.
• Check the motor connections and the
corresponding plug connector on the
device and, if necessary, the motor
terminal box.
• Correct start parameters for the motor
parameter identification (motor
nameplate data).
• Stable power supply of the device.
ID3: CINH motor data identification The device has detected controller inhibit
during the motor data identification.
• This cancels the identification process.
The Lenze setting of the motor data is
used.
• Do not set controller inhibit during the
motor data identification.
• Do not execute any device function
which may activate controller inhibit.
ID4: Resistor identification error The device has recognised that an error
has occurred in the calculation of the
motor cable resistance.
• The parameters for cable cross-section
and cable length are implausible.
Enter sensible values for cable cross-
section and motor cable length.
LP1: Motor phase failure Motor phase failure - power section
• This error message is displayed if a
motor phase carries less current of one
half-wave than set in C00599.
• Check the motor connections and the
corresponding plug connector on the
device and, if necessary, the motor
terminal box.
• Check the trigger threshold (C00599).
LU: DC bus undervoltage The device has detected a DC bus
undervoltage. The inverter control is
switched off because the drive properties
of the motor control cannot be provided
anymore due to the DC bus undervoltage.
• Depending on the configuration of the
auto-start lock function, C00142 serves
to set that, if this error has been
tripped, the controller only starts after
the controller inhibit is switched.
• Switch on mains supply or ensure
sufficient supply via DC bus.
• Adjust setting in C00142 if required.
MCI1: Module missing / incompatible The optional communication module has
been removed or there is a connection
problem or incompatibility with the
standard device.
• Check connection between the
communication module and standard
device.
• Check if the module is plugged in
correctly.
• In case of an incompatibility, either the
module or the software of the standard
device is out of date. In this case, please
contact Lenze.
OC1: Power section - short circuit The device has recognised a short circuit of
the motor phases. To protect the device
electronics, the inverter control is
switched off.
• Mostly, incorrectly executed motor
connections are the cause.
• If the device is inappropriately
dimensioned with regard to the motor
load and the current limitation in the
controller (Imax controller) is set
incorrectly, this error message may also
occur.
• Check motor connections and the
corresponding plug connector on the
device.
• Only use permissible combinations of
device power and motor power.
• Do not set the dynamics of the current
limitation controller too high.
