SafeMotion profiles
Selection
The safety functions of the "global safety functions" group cannot be selected
or deselected by activation signals. If they have been configured, they are
always active when the axis is in the operating mode (OM). The safety func-
tions take effect independently of the active safety technology operating status
(P‑0‑3231).
Diagnostics
There are no diagnostic status messages for the safety functions of "global
safety functions" group. The status (active / not active) of the individual safety
functions can be read using P‑0‑3264.0.1.
Normal operation
The safety technology operating state "normal operation" corresponds to
normal operation of the drive, e.g. as a servo positioning axis. In normal oper-
ation (also referred to as "production mode" or " automatic mode"), protec-
tive devices prevent human access to danger points. These protective devices
also prevent parts/material from being ejected. When "Safe Motion" is commis-
sioned, the parameter P‑0‑3277.0.1 is used to configure the safety functions
which are to be active in normal operation.
Safety functions
The following safety functions can be configured for normal operation (NO):
● Optional:
Selection
The normal operation is always selected when the activation signals emergency
stop signal (ES) and mode selection signal (MS) are not activated. When safety
technology detects a valid selection of the normal operation, switching to
normal operation takes place directly; there is no transition.
Diagnostics
There is no diagnostic status message for the safety technology operating
status "normal operation".
Via P‑0‑3262, it is possible to read out whether a selection for normal operation
exists.
Using a status bit in P‑0‑3231, the safety technology signals whether normal
operation is active or not.
Special mode "EMERGENCY STOP" (SMES)
In
"EMERGENCY STOP" (SMES) is the safety technology operating status of
the highest priority. That is to say, if the special mode "EMERGENCY STOP"
is selected at an axis, the axis always goes to the special mode
"EMERGENCY STOP". This transition is independent of whether another valid
selection for a special mode has been made or whether the axis already is in a
special mode.
Typically, the special mode "EMERGENCY STOP" is used to implement the
EMERGENCY STOP function of a machine.
Safety functions
In the special mode "EMERGENCY STOP" (SMES), the following safety func-
tions are active:
