3.10.5.2 Alarm triggering

(1) AL500 (STO function is activated)

When either SF1 signal or SF2 signal becomes OFF, the STO function is activated, the

circuit cuts off the current to the motor within 10 ms, and the servo drive is Off, triggering

AL500.

When both SF1 and SF2 signals become OFF, the servo drive still displays AL500. Refer to

the following diagram.

The panel displays either “AL500” or “-STO-” according to the setting of P1.120.
