Safety faults
The fault messages of the Safety Integrated Basic Functions are saved in the standard
message buffer and can be read out from there.
When faults associated with Safety Integrated Basic Functions occur, the following stop
responses can be initiated:
Table 5- 1
Stop response
STOP A cannot be
acknowledged
STOP A
STOP F
With a vertical axis or pulling load, there is a risk of uncontrolled axis movements when
STOP A/F is triggered. This can be prevented by using "Safe Brake Control (SBC)" and a
holding brake (not a safety brake!) with sufficient holding force.

As a follow-up
reaction of STOP F.
STOP A corresponds to Stop Category 0 to EN 60204-1.
With STOP A, the motor is switched directly to zero torque via the "Safe Torque
Off (STO)" function.
A motor at standstill cannot be started again accidentally.
A moving motor coasts to standstill. This can be prevented by using external
braking mechanisms, e.g. holding or operating brake.
When STOP A is present, "Safe Torque Off" (STO) is active.
If an error occurs in
the data cross-
check.
STOP F is permanently assigned to the data cross-check (DCC). In this way,
errors are detected in the monitoring channels.
After STOP F, STOP A is triggered.
When STOP A is present, "Safe Torque Off" (STO) is active.
WARNING
Safety Integrated Basic Functions
Action
Trigger safe pulse
suppression via the
switch-off signal path for
the relevant monitoring
channel. During operation
with SBC:
apply motor holding
brake.
Transition to STOP A.
5.4 Safety faults
Effect
The motor coasts to a
standstill or is braked by the
holding brake.
Follow-up response STOP A
with adjustable
delay (default setting without
delay) if one of the Safety
functions is selected
