Parameter Edit Commands
Function/Description
Parameter Read
Reads a parameter.
ppp: Parameter number (Pn number)
Example: Reading PnB00
Command: 1PRMB00 [CR]
Response: 1PRMB00 = 00000001 [CR] [LF]
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: Parameter settings are either enabled immedi-
ately or after restarting the power supply. For
details, refer to 10.1 Parameter List for
INDEXER Module.
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 com-
mand does not write the setting in EEPROM, it can
be used to change settings frequently.
Note: Parameter settings are either enabled immedi-
ately or after restarting the power supply.
To edit parameters that are enabled after
restarting, use the PRMppp = (±) nnnnnnnn
command instead of the TRMppp =
(±) nnnnnnnn command. For details, refer to
10.1 Parameter List for INDEXER Module.
Positive Response
An 8-digit signed decimal value is returned for
commands PRM124, PRM164, PRM165, PRM550
to PRM553, PRMB21, PRMB23, PRMB25,
PRMB39, and PRMB50.
Example: PRMB21 = +12345678 [CR] [LF]
An 8-digit hexadecimal value is returned for com-
mands PRM000 to PRM002, PRM006 to PRM
009, PRM00B to PRM00D, PRM010, PRM10B,
PRM139, PRM140, PRM160, RPM170, PRM310,
PRM408, PRM460, PRM530, PRM587, PRMB53.
Example: PRM000 = 00001234 [CR] [LF]
A 10-digit unsigned decimal value is returned for
commands PRM20E, PRM210, PRM212,
PRM520, PRM526, and PRM531.
Example: PRM20E=1234567890 [CR] [LF]
An 8-digit unsigned decimal value is returned for
all other parameters.
Example: PRMB00 = 12345678 [CR] [LF]
