The "T option" monitors whether the dynamization of the selection signals is
carried out in the deselected state. Monitoring takes place so that
dynamization is carried out at the latest after 1 hour in the deselected state
(normal operation). For this purpose, the time in the deselected state is
added in the drive and only reset by dynamization. That is to say an interim
selection does not cause monitoring to be reset. Monitoring takes place
independently for both selection channels. If the time interval of dynamization
is exceeded, an error message is generated (F3134).
To increase the noise immunity, the safety technology tolerates
the failure of a dynamization pulse, if the following 8 dynamization
pulses occur within the time window described above.
Dynamization pulses of a duration of 100 µs and more are recognized as
valid dynamization pulses.
The sampling ratio of the dynamization pulse is also monitored by the safety
technology. The dynamization pause has to be at least 90% of a
dynamization period. If the dynamization pause is shorter, an error message
is generated (F8300).
Requirements on the command
value input
Before selecting the safety function "Safe Torque Off", the drive
system has to be decelerated via the command value input; there
is no drive-controlled deceleration!
The safety function "Safe Torque Off" complies with stop
category 0 according to EN 60204‑1.
If the safety function "Safe Torque Off" is selected with drive enable having
been set, the safety function is executed while a diagnostic message is
generated at the same time, because the drive first has to be decelerated
before the safety function is allowed to be activated.
Via the configuration of "Safe Torque Off" (P‑0‑0101) select how the drive is
to react if the safety function "Safe Torque Off" is selected with drive enable
having been set ‑ with a fatal error or a fatal warning (F8027 or E8027).
The warning is automatically cleared when drive enable is removed, the error
has to be cleared by the user.
Diagnostic messages are logged in the diagnostic trace for main
diagnostics (S‑0‑1303.0.10).
Lethal injury and/or property damage caused
by coasting axes!
DANGER
⇒ If the safety function "Safe Torque Off" is selected with drive enable having
been set, the drive torque, independent of the diagnostic message which was
set, is immediately disabled and the drive coasts to stop. The deceleration
process is relatively slow and, above all, not safe!
Selecting the safety function "Safe
Torque Off"
The safety function "Safe Torque Off" always has to be selected via two
channels.
The selection of the safety function is detected when a "0"-signal is detected
on both selection inputs. The selection can alternatively be made via active or
passive safety units.
