Software Disconnection (Closed Loop)

Was bedeutet Alarm 2 ?

This alarm is issued when the change in position feedback pulses is relatively small for the change in velocity feedback pulses. This condition typically occurs in a closed-loop system and is not issued with the semi-closed loop.

• The closed-loop control system has lost its feedback signal.
• Software error preventing the system from establishing a closed loop.
• Encoder or sensor is not providing valid position data.
• Communication failure with the position feedback device.

1. 1

   Check whether the separate detector outputs position feedback pulses correctly.

2. 2

   If the detector outputs pulses correctly, investigate for a large backlash between the motor position and scale position causing reverse rotation of only the motor at the start of machine operation.
