Position control under vector control and PM sensorless vector control Parameters
5 - 168
●
Set "0" as the dwell time to perform variable speed operation.
Example of positioning operation by point tables (automatic continuous positioning operation
using the point table selected at the start of the operation)
●
When the operation is repeated from the point table 2 to 4.
●
Setting: The operation is started using the point table 2 (start point). Set "12" in the auxiliary
function of the point table 4 (end point).
The positioning operation is repeated. To stop the operation, turn OFF the STF (STR) signal, or turn
ON the X87 (sudden stop) input signal.
●
Operation sequence
The operation is started using the point table 2 (start point).
The operation is switched to use the point table 3.
The operation is switched to use the point table 4 (end point).
According to the setting in the auxiliary function for the point table 4 (Pr. 1237 = "12"), the
operation is switched to use the point table 2 selected at the start (loops back the start point from
the end point).
$
Steps to are repeated.
