Amplitude loggers
The control program has two amplitude loggers. Depending on the setting of
parameter
, the loggers are active continuously or only when the drive is
modulating.
For amplitude logger 2, the user can select a signal to be sampled at 200 ms
intervals, and specify a value that corresponds to 100%. The collected samples are
sorted into 10 read-only parameters according to their amplitude. Each parameter
represents an amplitude range 10 percentage points wide, and displays the
percentage of the collected samples that have fallen within that range. Note that
the lowest range also contains the negative values (if any), while the highest range
also contains the values above 100%.

Percentage
of samples
Amplitude logger 1 is fixed to monitor motor current, and cannot be reset. With
amplitude logger 1, 100% corresponds to the maximum output current of the drive
(

User parameter sets
The drive supports four user parameter sets that can be saved to the permanent
memory and recalled using drive parameters. It is also possible to use digital inputs
to switch between user parameter sets.
A user parameter set contains all editable values in parameter groups 10…99
