8.5.10 Safe Direction (SDI)
8.5.10.1 Safe Direction with encoder
The Safe Direction function (SDI) allows reliable monitoring of the direction of motion of the
drive. If this function is activated, the drive can only move in the enabled, safe direction.
Functional principle
After SDI has been selected via terminals or PROFIsafe, the delay time p9365/p9565 is
started. During this period, you have the option of ensuring that the drive is moving in the
enabled (safe) direction. After this, the Safe Direction function is active and the direction of
motion is monitored. If the drive now moves in the non-safe direction, messages
C01716/C30716 are output and the stop response defined in p9366/p9566 is initiated.
