SOS safety sub-function with MOVISAFE^® CS..A

INFORMATION

The SOS safety sub-function must not be used in conjunction with the EI7C FS built-in encoder.

The SOS safety sub-function monitors the drive position with the parameterized positional tolerance.

If the Inverter control parameter is set to "Active", activating the SOS safety sub-function results in the activation of the FCB19 Position hold control drive function in the inverter.

If the Inverter control parameter is set to "Not active", activating the SOS safety sub-function does not result in the activation of the FCB19 Position hold control drive function in the inverter. The user must use the correct controller to ensure that the drive remains in an idle state. The positive and negative limit position is determined based on the actual position and the parameterized positional tolerance detected upon activation of the SOS safety sub-function.

If the positive or negative limit position is exceeded, the fault response (STO) is triggered. After a limit value violation, acknowledgment leads to the limit positions being recalculated based on the current actual position.
