STO.STATE

Description

STO.STATE returns the status of the safe torque off.

AKD-x003 up to AKD-x024 (one STO channel)

Value Description
1 Safe torque on (no STO fault/warning)
0 Safe torque off (STO fault and warning are present)

1 - Safe torque on (no safe torque off fault/warning).

0 - Safe torque off (safe torque off fault/warning).

When STO.STATE = 1, the drive can be enabled.
