The value limit violation must be acknowledged. By deactivating the SSx function, the
limit value violation is not acknowledged. The SSx function cannot be reactivated with
an existing limit value violation. The fault can only be acknowledged if the SSx func-
tion is deactivated. After fault acknowledgment, the final state of the SSx function is
active immediately.
Encoder fault
If an encoder fault occurs, the STO drive safety function is activated immediately
without brake application delay. The status of the SSx function becomes inactive. The
encoder fault must be acknowledged. The encoder fault cannot be acknowledged by
deactivating the SSx function.
INFORMATION
If an SSx instance is assigned to another drive safety function as fault response, the
SLI function cannot be parameterized as finale state.

SS2(c) drive safety function with MOVISAFE
®
CS..A
The SS2(c) drive safety function monitors the parameterized time delay and triggers
the SOS drive safety function after the time delay elapsed.
If the parameter
Inverter control
is set to "active", activating the SS2(c) drive safety
function results in the activation of the
FCB19 application stop
drive function in the in-
verter.
If the parameter
Inverter control
is set to "Not active", the inverter is not controlled.
Activation
Number of instances: 2 (SSx1, SSx2)
The drive safety function can be activated by the following sources:
•
F-DI (function assignment)
•
Safe process output data (SSx1, SSx2)
Status
The status of the drive safety function is displayed in the following areas:
•
MOVISAFE
®
CS..A diagnostics, speed function status
•
Safe process input data (SSx1, SSx2)
Limit value violation
Due to the value limit violation, the STO drive safety function is activated without brake
application delay.
The value limit violation must be acknowledged. By deactivating the SSx function, the
limit value violation is not acknowledged. The SSx function cannot be reactivated with
an existing limit value violation. The fault can only be acknowledged if the SSx func-
tion is deactivated. After fault acknowledgment, the final state of the SSx function is
active immediately.
