② The positive end position has been reached. The motor stops with the OFF3 ramp-down time.
③ The higher-level control system issues a negative setpoint.
With a signal change 0 → 1 at p3340, the motor moves the machine component in the direction of
"Limit switch minus".
④ The negative end position has been reached. The motor stops with the OFF3 ramp-down time.
⑤ The higher-level control system issues a positive setpoint.
With a signal change 0 → 1 at p3340, the motor moves the machine component in the direction of
