Mitsubishi Electric MELFA CR800 Series Instruction Manual page 57

The matrix in the Safety Input screen has rows representing safety inputs (DSI, AREA, LOGIC, MODE). The
columns represent safety monitoring start commands for each safety function (SS1, SS2, SLS1, SLS2, SLS3,
SLSM, SLP1, SLP2, SLP3, SLPM).
Checking intersections of the rows and columns defines safety functions started when the individual safety inputs
are enabled.
Example 1: To start the safely-limited speed function 1 (SLS1) when DSI2 is enabled, check the intersection of
DSI2 and SLS1 as shown in Fig 4-17.
Also, one safety input can start multiple safety functions.
Example 2: Enabling DSI3 starts SLS1, SLS2, and SLP1 and enabling DSI4 starts SLS3.
