<Control location selection>
In the computer link operation mode, operation can be performed by signals from
external terminals in accordance with the settings of Pr. 338 "operation command right"
and Pr. 339 "speed command right".

: Only control by signal from external terminal is valid.
Computer
: Only control from sequence program is valid.
Both
: Only control from both external terminal and computer is valid.
: Control from both external terminal and computer is invalid.
Note:
When "7" is set in Pr. 79 (when the PU operation interlock function is
selected), only operation from external terminal is valid independently of the
Pr. 338 and Pr. 339 settings.
