“FCR3 three-phase controller” +030222150 - rel. 1.3 - 12.01.2021
7. DESCRIPTION OF THE OPERATING PARAMETERS
MAC Type of unit
Read in REPORT SLAVE ID (read-only)
Indirizzo Modbus read input register 12
range 311
default 311
Non-modi able parameter used to identify the type of controller for
connection to a supervisor or the programming key.
REL Software release
Read in REPORT SLAVE ID (read-only)
Indirizzo Modbus read input register 13
resolution and unit of measure 1
range 0 to 255
default --
Non-modi able parameter used to identify the software version installed
on the controller. The least signi cant digit is used to identify functional
variations that do not imply changes to the parameter structure.
Parameters can only be copied between FCR controllers using the
programming key if the corresponding REL parameters are identical or
only the least signi cant digit is di erent (for example: copying is possible
between controllers with REL 12 and 14, while it is not possible between
controllers with REL 12 and 20). HW Even in INPUT REGISTER 14
HW Hardware release
Read hardware version (read-only)
Indirizzo Modbus read input register 14
resolution and unit of measure 1
range 0 to 255
default --
Non-modi able parameter used to identify the hardware version
TV/TI Hardware release
Read hardware model (read-only)
Indirizzo Modbus read input register 15 e 16
resolution and unit of measure 1
range
TV 23/40 – TI
06/09/12/20/40
default --
Non-modi able parameter used to identify the operating voltage and
current

HZMEM Select frequency by internal parameter
Modbus address read/write coil 2
resolution
and unit of measure
1
range 0/1
default 0
This parameter is used to select the operating frequency of the FCR
controller
• HZMEM=0 50 Hz
• HZMEM=1 60 HZ
LINMEM Select operating curve
Modbus address read/write coil 3
resolution
and unit of measure
1
range 0/1
default 0
This parameter is used to select linear or quadratic control
• LINMEM=0 linear
• LINMEM=1 quadratic
MINCUTMEM Select minimum/cut-o mode
Modbus address read/write coil 4
resolution
and unit of measure
1
range 0/1
default 1
This parameter is used to select how the controller responds to no control
signal (when INFCR = 0 or INMEM = 0)
• MINCUTMEM=0 minimum
• MINCUTMEM=1 cut-o
BAUD1MEM /
BAUD2MEM
Select baud rate
Modbus address read/write coil 5 and 6
resolution
and unit of measure
1
range 0/1
default 1 & 0
Parameter used to select the serial line baud rate
Value BAUD1MEM BAUD2MEM
9600 0 0
19.200 1 0
38400 0 1
FDEF Reset default
Modbus address read/write coil 7
resolution
and unit of measure
1
range 0/1
default 0
Parameter used to reset the default values
• FDEF=0 no action
• FDEF=1 load default parameters
(also saved) – one-time action
SAVE Save to memory
Modbus address read/write coil 8
resolution
and unit of measure
1
range 0/1
default 0
Parameter used to save the parameter values to the internal memory
• SAVE=0 no action
• SAVE=1 save the parameters to the internal EEPROM:
one-time action
IOVR Override input
Modbus address read/write coil 9
resolution
and unit of measure
1
range 0/1
default 0
Parameter used to override the input using a value set in the memory
(INMEM)
• IOVR=0 no override
• IOVR=1 enable override
