0021 STO1 LOST
(0x8182)
Safe Torque Off function is
active, i.e. safety circuit signal 1
connected between X6:1 and
X6:3 is lost while drive is at
stopped state and parameter
46.07 STO DIAGNOSTIC
setting is (2) Alarm or (3) No.
Check safety circuit connections. For more
information, see the appropriate drive
hardware manual and Application guide -
