param_read BOOL IN 0 = Reading of parameter value is not
requested. The parameter value at the
output "value_32" does not need to be
valid.
1 = Reading of parameter is requested. This
signal may be used as a static signal.
The output bits "valid" and " busy" are
updated together with the read
command.
X X
value_16 WORD IN The 16 bit numerical value for the parameter
which is to be written is entered here. For
details of which parameters have a 16 bit
numerical value, please refer to the manual
for the frequency inverter.
X X
value_32 WORD IN The 32 bit numerical value for the parameter
which is to be written is entered here. For
details of which parameters have a 32 bit
numerical value, please refer to the manual
for the frequency inverter.
X X
param_write BOOL IN 0 = Writing of the parameter value is not
requested.
1 = Writing of the parameter is requested.
From this signal, the module forms a
positive flank, which means that the
signal must change from 0 -> 1 for for
the parameter to be re-written. X X
write_RAM BOOL IN 0 = Writing of the parameter value is not
requested.
1 = Writing of the parameter is requested.
From this signal, the module forms a
positive flank, which means that the
signal must change from 0 -> 1 for for
the parameter to be re-written. The
parameter is only written to the RAM.

BOOL IN 0 = Writing of the parameter value is not
requested.
1 = Writing of the parameter is requested.
From this signal, the module forms a
positive flank, which means that the
signal must change from 0 -> 1 for for
the parameter to be re-written. The
parameter is written into the EEPROM
and cannot be written an unlimited
number of times.
