Fig. 6-2 Block Diagram of In-built PLC function with Main Control
Fig. 6-2 is a block diagram of main control and In-built PLC function. All Digital Input and Output,
Analog Input and output are connected with main control.
Now user can program In-built PLC for his application. User can also take output of the drive as PLC
Input and output from PLC to the drive as an Input.
In-built PLC Function Related Parameters and Command.
The In-built PLC function related parameters are listed below.
1. In-built PLC (C312):
Use this parameter to enable the In-built PLC Function.
2. In-built PLC Command (P101 to PC10):
Input the PLC commands to be executed with the In-built PLC Function in parameters P101 to
PC10.
3. PLC Display Parameter (M313 to M322): In-built PLC 

 Display
For PLC programming, there are 115 numbers of 16-bit register and 100 numbers of 1-bit flag.
10 values of signed 16-bit register can be displayed in parameter M313 to M322 and these values
will be saved in EEPROM at the time of power off. (Related PLC command is DISPLAY_REG
(061)) and during power on these parameters value will come in register 76 to 85, 8 different flag
bit status can be display in parameter M323. (Related PLC command is DISPLAY_FLG (062)).
4. Digital Input From Inverter (PSI Status) to In-built PLC:
Parameters C101 to C106 and C114 to C115 have 41 selectable options. In these, 28 to 35 are
for PLC input options. Now to take PSI status as a PLC input, select one of the PLC input option
from these parameters. Use READ_PSI (047) command in PLC program for this operation.
5. Digital Output From In-built PLC to Inverter (PSO Status):
Parameters C107 to C113 have 36 Selectable options. In these, 26 to 32 options are for In-built
PLC output. Now to take In-built PLC’s output as Inverter’s PSO output, select one of the PLC
option from these parameters. Use WRITE_PSO (049) command in PLC program for this
operation.
6. Digital Input From In-built PLC to Inverter (PSI Status):
Parameters C101 to C106 and C114 to C115 have 41 selectable options.
User can activate one of 1 to 27 options of these parameters, without any extern digital signal on
PSI by using In-built PLC. Use WRITE_PSI (048) command in PLC program for this operation.
7. Digital Output From Inverter (PSO Status) to In-built PLC:
User can read and use status of PSO from inverter for In-built PLC application.
To read the PSO status in In-built PLC, use READ_PSO (046) command in PLC program.
