This parameter is read-only.
-
0000h…FFFFh Process PID control status word. 1 = 1
40.07 Process PID operation
mode
Activates/deactivates process PID control.
Note: Process PID control is only available in external
control; see section Local and external control locations
(page 50).
Off
Off Process PID control inactive. 0
On Process PID control active. 1
On when drive running Process PID control is active when the drive is running. 2
