1.3.10.2 Activation
How to activate the "Safe direction" function:
ƒ Permanent monitoring of the direction of movement during normal operation
(C15340).
ƒ "OFF state" at a safe input, the function of which has been assigned by parameter
setting.
ƒ In conjunction with safely limited speed SLSx (C15333).
ƒ Via a safety bus data telegram with corresponding content.
