Customising the Process Area
Section 4-3
Tip
If the Inverter trips after restarting, check that you correctly set P161, P162,
P171 and P172, and that all other registers in the P160 - P179 range are set
to 0.
Your input and output process areas should now have the following layout:
Table 24 Output Process Area with Double Word Frequency Reference
Table 25 Input Process Area with Double Word Output Frequency
Step 5 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 26 Output Process Area with Forward Rotation Dword Frequency Reference
The output frequency is given by d001 (input PZD2 contains the most-signifi-
cant and input PZD3 the least-significant word).
Table 27 Input Process Area with Forward Rotation Dword Output Frequency
Step 6 To reverse the motor, change F001 (output PZD2 and PZD3) to a negative
signed double-word frequency.
Table 28 Output Process Area with Reverse Rotation Dword Frequency Reference
The motor decelerates, stops and then accelerates in the opposite direction.
Table 29 Input Process Area with Reverse Rotation Dword Output Frequency
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 Inverter).
