SIMODRIVE 611 universal Description of Functions (FBU) – 04.05 Edition
If the power–on inhibit is activated (P1012.12 = 1), the drive can no
longer move by itself after the ”power–on inhibit” has been reached.
The ”power–on inhibit” status must be removed in order to traverse the
drive.
In order to activate the behavior/response in conformance with the
PROFIdrive from SW 6.1, bit 13 (power–on inhibit according to the
PROFIdrive Profile) is pre–assigned a value of 1 in parameter P1012
(function switch). This means that the behavior/response, in confor-
mance with PROFIdrive, is activated as standard.
Fig. 5-9 indicates which signals and parameters affect the power–on
inhibit.

Generating the power–on inhibit
Note
If, in addition to P1012.13=1 also P1012.14=1 is set to 1, if the status
of signals STW1.1 (OC/OFF 2), STW1.2 (OC/OFF 3 and STW1.0
(ON/OFF 1) simultaneously change
from 0 ––> 1, this does not result in the ”power–on inhibit” state.
Removing the power–on inhibit?
If there is no longer a setting condition for the power–on inhibit, then it
can be removed as follows:
Withdraw the controller enable, terminal 65.x, or
Reset control signal STW1.0
Switching out the power–on inhibit?
The power–on inhibit can be switched–out with P1012.12 = 0.
