Serial Command
Parameter Write
Sets a parameter.
ppp: Parameter number (Pn number)
Parameters are stored in EEPROM, so the
settings will be retained after the control
power supply is turned OFF. Because the
value is stored in EEPROM, this command
must not be used if the setting needs to be
changed frequently. In such a case, use the
PRMppp =
TRMppp = (±) nnnnnnnn command.
(±) nnnnnnnn*
Note: The settings of parameters are updated at
Refer to the following section for the timing
of enabling parameter settings.
Temporary Parameter Write
Sets a parameter.
ppp: Parameter number (Pn number)
The PRMppp = (±) nnnnnnnn command
stores the parameter setting in EEPROM,
but the TRMppp = (±) nnnnnnnn command
does not. Because this command does not
write the setting in EEPROM, it can be used
to change settings frequently.
Note: The settings of parameters are updated at
TRMppp =
(±) nnnnnnnn*
Refer to the following section for the timing
of enabling parameter settings.
