SDI with time monitoring
This applies when the motor rotates into the forbidden direction when the SDI
function is activated and the time monitoring method is used. The SDI positive
function is used as an example.
A
SDI delay (parameter
): Delay for forcing to start the SDI monitoring.
B
Zero speed with encoder (parameter
): Speed limit to define the motor as
stopped. The safety function is completed and the SSE completed indication (parameter
) goes on. The STO acknowledgment becomes allowed.
