P9692 = P9892 = 0
If, after initiation of SLS, the motor exceeds the upper SLS limit set with P9691 and P9891,
then the latched STO (LSTO) function is initiated to bring the motor to a standstill.
If the motor speed is below the upper SLS limit, all control signals that can affect the speed
of the motor are blocked. No external control of the motor speed is possible.
Once the motor is locked at its present speed, if the motor again falls below this speed (for
example additional load on the motor), it is not interpreted as a fault condition and no action
is taken. See the following table.
During SLS mode 0 is active the the fault reaction time for a STO is given according to the
