Operation with Serial Command Communications

If you set PnB54 to 1 (Enable Expansion Mode), the command name will change. Refer to the following section for
details.
12.4 Speed/Position Expansion Function Setting
PRMppp =
(
±
) nnnnnnnn
*
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
TRMppp = (
±
) nnnnnnnn command.
Note: The settings of parameters are updated at
one of the following two times.
Immediately: The setting of the parameter
is enabled immediately.
After restart: The setting of the parameter is
enabled the next time the control power
supply is turned OFF and ON again.
Refer to the following section for the timing
of enabling parameter settings.
OK
TRMppp =
(
±
) nnnnnnnn
*
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
one of the following two times.
Immediately: The setting of the parameter
is enabled immediately.
After restart: The setting of the parameter is
enabled the next time the control power
supply is turned OFF and ON again. You
cannot use the TRMppp = (
±
) nnnnnnnn
command to edit parameters that are
enabled after turning the control power
supply OFF and ON again. Use the
PRMppp = (
±
) nnnnnnnn command.
Refer to the following section for the timing
of enabling parameter settings.
OK
PRMINIT
Parameter Initialization
Resets all parameters to their default set-
tings.
After executing PRMINIT, turn the control
power supply OFF and ON.
OK
