Servodrive Behavior
Servodrive remains in STO state and does
not accept commands. The servodrive
indicates "STO" on the keypad
Servodrive trips to Fault "F0160" if this status
lasts longer than 1 s
To reset the fault, both contacts must be at
the same status and the +24Vdc supply must
be deenergized and reenergized
Servodrive accepts commands normally
