(FF81)
Excessive input choke temperature Stop drive. Let it cool down.
Check ambient temperature.
Check that fan rotates in correct direction and
air flows freely.
INV CUR LIM
(2212)
Internal inverter current or power limit has
been exceeded.
Reduce load or increase ramp time.
Limit inverter actual power or decrease line-
side converter reactive power generation
reference value (parameter 95.06).

40 °C, ensure that load current does not
exceed derated load capacity of drive. See
appropriate hardware manual.
Check that ambient temperature setting is
correct (parameter 95.10).
Check converter module cooling air flow and
fan operation.
Cabinet installation
: Check cabinet air inlet
filters. Change when necessary. See
appropriate hardware manual.
Modules installed in cabinet by user: Check
that cooling air circulation in cabinet has been
prevented with air baffles. See module
installation instructions.
Check inside of cabinet and heatsink of
converter module for dust pick-up. Clean when
necessary.
IO CONF Input or output of optional I/O extension or
fieldbus module has been selected as signal
interface in control program but communication
