6�2 Switching Function Rotational Speed - IFM RM 3 Series Operating Instructions Manual

6.2 Switching function rotational speed
SSC2�x changes its switching state if it is above or below the set switching limits
(SP1, SP2).
First set the set point (SP1), then the reset point (SP2).
The resulting hysteresis remains even if SP1 is changed again�
• Window function / normally open: [SSC2�x] = [Fno]
• Window function / normally closed: [SSC2�x] = [Fnc]
The width of the window [FE] can be set by means of the difference between
SSC2�1 and SSC2�2�
SP1 = upper value, SP2 = lower value�
