Introduction
WARNING
HIGH VOLTAGE
Disconnect all electric power, including remote
disconnects. Follow proper lockout/tagout procedures to
ensure the power cannot be inadvertently energized.
Verify with an appropriate voltmeter that the unit is
discharged. Failure to disconnect power and ensure unit
is discharge before servicing could result in death or
serious injury.
Make sure that other voltage inputs have been discon-
nected, such as load sharing (linkage of DC intermediate
circuit)
Systems where frequency converters are installed must,
if necessary, be equipped with additional monitoring
and protective devices according to the valid safety
regulations, e.g law on mechanical tools, regulations for
the prevention of accidents etc. Modifications on the
frequency converters by means of the operating
software are allowed.
Failure to follow recommendations could result in death
or serious injury.
NOTICE
Hazardous situations shall be identified by the machine
builder/integrator who is responsible for taking
necessary preventive means into consideration.
Additional monitoring and protective devices may be
included, always according to valid national safety
regulations, e.g. law on mechanical tools, regulations for
the prevention of accidents.
Protection Mode
Once a hardware limit on motor current or DC-link voltage
is exceeded, the frequency converter enters Protection
mode. Protection mode means a change of the PWM
modulation strategy and a low switching frequency to
minimise losses. This continues 10 s after the last fault and
increases the reliability and the robustness of the
frequency converter while re-establishing full control of the
motor. Parameter 0-07 Auto DC Braking may cause PWM
when coasted.

The maximum output current.
I
DRIVE,N
The rated output current supplied by the frequency
converter.
U
DRIVE, MAX
The maximum output voltage.
Input
The connected motor can
start and stop with LCP and
the digital inputs.
Functions are divided into 2
groups.
Functions in group 1 have
higher priority than
functions in group 2.
