(1) Operation mode setting write (D9143)
Data are as follows:
Data Setting
H0000
H0001
H0002
The operation mode switching method is as shown below when the Pr.79
Operation mode selection value is "0".
When Pr. 79 =2, switching is performed as shown below.
REMARKS
When Pr. 79 is other than 0, the mode is fixed.
There are no restrictions on operation mode switching.
On normal completion of operation mode setting, the write completion signal
(X23) turns on, and at the same time, 0 is set to D9150.
If the value written is other than H0000 to H0002 or write is performed during
inverter operation, HFFFF is set to D9150 as soon as the write completion signal
(X23) turns on, resulting in abnormal completion.
If abnormal completion occurs, the operation mode is not changed.
<Operation mode setting write program example>
The following program changes the operation mode to the NET mode.
