Over-speed Protection in Reversed Direction

¿Qué significa 18 ?

This error indicates that the motor speed has exceeded a safe limit while traveling in the reverse direction of the intended 'riding' or forward direction. This is a critical safety fault, often triggered by unintended reverse motion or a severe control issue.

• Unintended reverse rotation of the motor despite a forward command or no command.
• Loss of speed control by the drive leading to uncontrolled reverse motion.
• Incorrect over-speed protection threshold setting for reverse direction in drive parameters.
• Malfunctioning speed feedback device providing incorrect direction information.

1. 1

   Verify that no reverse run command signals are active if forward motion is expected.

2. 2

   Check for external forces or mechanical conditions that could be causing unintended reverse rotation of the motor.

3. 3

   Review and adjust the over-speed protection threshold parameter for the reverse direction in the drive's settings.

4. 4

   Inspect the speed feedback device (encoder) for proper operation and correct direction sensing.
