296 Parameters
40.06 Process PID status
word
Displays status information on process PID control.
This parameter is read-only.
0b0000
0b0000…0b1111 Process P ID co ntrol 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 control vs. external control (page
33).
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
40.08 Set 1 feedback 1
source
Selects the primary source of process feedback. See the
control chain diagram on page 495.
