9. COMMUNICATION DATA DESCRIPTION
IMS01T28-E4
9-98
PFF reference voltage
RKC communication
identifier JP
Modbus
register address 042BH (1067)
The reference voltage of the Power feed forward (PFF) is set here.
Attribute: R/W
Digits:
7 digits
Number of data: 1 (Data of each module)
Data range:
0.0 to 300.0 V
Factory set value: 0.0
Related parameters:
PFF power supply frequency (P. 9-95),
Power feed forward (PFF) selection (P. 9-96),
Measurement power supply frequency (P. 9-97), PFF input voltage (P. 9-97),
Output compensation factor for PFF reference voltage (P. 9-98),
Output compensation captured value for PFF reference voltage (P. 9-99),
PFF gain (P. 9-99)
Function:
Captures PFF input voltage as PFF reference voltage at the time of power-on,
switching the mode from STOP (control stop) to RUN (control start), and changing
the set value (SV).
This parameter is activated when the Power feed forward (PFF) input is used.
The PFF reference voltage is automatically taken in and set by the instrument under the normal
operation. Users do not need to set this parameter by themselves.
Output compensation factor
for PFF reference voltage

identifier JQ
Modbus
register address ch1: 042CH (1068)
ch2: 042DH (1069)
Set the output compensation factor of the Power feed forward reference voltage.
Attribute:
