Customising the Process Area
Step 5
Step 6
22
Your input and output process areas should now have the following layout:
Table 23 Output Process Area with Double Word Frequency Reference
Word offset +0
Register PKE
dec 0
Value
hex 0000
Table 24 Input Process Area with Double Word Output Frequency
Word offset +0
Register PKE
dec 0
Value
hex 0 0 0 0
To turn the motor forward, set the Run and En bits in STW and change F001
(output PZD2 and PZD3) to the desired frequency. (Input PZD2 represents
the most-significant word and input PZD3 the least-significant word)
Table 25 Output Process Area with Forward Rotation Dword Frequency Reference
Word offset +0
Register PKE
dec 0
Value
hex 0000
The output frequency is given by d001 (input PZD2 contains the most-signifi-
cant and input PZD3 the least-significant word).
Table 26 Input Process Area with Forward Rotation Dword Output Frequency
Word offset +0
Register PKE
dec 0
Value
hex 0000
To reverse the motor, change F001 (output PZD2 and PZD3) to a negative
signed double-word frequency.
Table 27 Output Process Area with Reverse Rotation Dword Frequency Reference
Word offset +0
Register PKE
dec 0
Value
hex 0000
The motor decelerates, stops and then accelerates in the opposite direction.
Table 28 Input Process Area with Reverse Rotation Dword Output Frequency
Word offset +0
Register PKE
dec 0
Value
hex 0000
The remainder of the examples do not make use of double-word frequency
registers. Set P160, P161, P170 and P171 back to 0, A001 back to 4 and
restart the Inverter or reset the Option Board before following further exam-
ples.
Note If you want to use a DINT to write or read an Inverter double-word register,
you will have to swap the high- and low-word in your PLC program (For dou-
ble-words, an OMRON PLCs does not use the same word-order convention
than the MX2-A@ Inverter).
