and send "Command request" signal again (I/F for suspension and resume is the same as

Robot operation
<Handling on error occurrence>
(1) When H or L level error occurs in the robot while performing the sequencer direct, the operation is
suspended. The robot sends "Command running OFF", sets "Completion status" to 30 (suspended),
and sends "Command completed ON".
(2) When the sequencer receives "Command completed ON", the sequencer imports "Completion sta-
tus" and sends "Command request OFF".
(3) When the robot receives "Command request OFF", the robot clears "Completion status" and "Com-
mand data" to zero and sends "Command completed OFF".
<Error reset handling>
(4) Error reset operation clears the robot error.
<Resume handling>
(5) When a resume operation is carried out in the sequencer, the sequencer sets up "Command data"
and "Condition data" and sends "Command request ON".
(6) When "Command request ON" from OFF is received, the robot imports "Command data" and "Condi-
tion data", sets up "Command data" (returned data), sends "Command running ON", and carries out
the instructed robot operation.
