8.11 Special Functions Parameters (LX)
LX01 Auto Reset
faults, can be
automatically reset.
The number adjusted in this parameter determines how many times per hour the elevator
drive will automatically reset faults. Before resetting the fault, the drive will wait 4 seconds
to allow everything to stop or stabilize. It is not fault specific, so with the default setting of
5, if the drive experiences 6 different faults in one hour, the unit will latch the last fault and
not reset.
Overload and overtemp faults are not reset until the overload counter
resets or the temperature value drops to the reset level.
LX02 Switching Frequency
The switching frequency of the inverter can be set with this parameter. The switching
frequency can be constantly 8 kHz or 16kHz, each with an automatic reduction based on
the heat-sink temperature.
For optimum drive performance, set LX02 to 8kHz (NUM 2). In some cases,
higher switching frequencies may
it will not be possible to increase the switching frequency.
