When the motor runs normally (Servo On), but one of the safety signal source is low for 1s,
AL501 or AL502 occurs. Then the servo drive is in the Servo Off state.

3.10.5 Related parameter of the STO function
By setting parameter P2.093, you can determine the FDBK status (Pin FDBK+ and FDBK-) and
whether FDBK latches if an STO alarm occurs. The structure for P2.093 is shown below:
P2.093= XX 1

STO function description:
See the table below. Four logic conditions (Logic A, B, C, and D) are available to standardize the
FDBK status when different STO alarms occur. You can select the corresponding logic according
to the needs of the application. In this table, “Open” means FDBK+ and FDBK- of CN8 are an
open circuit. Take Logic C as an example: when AL500 occurs, FDBK+ and FDBK- of CN8 are
short circuited.
