Following error (velocity) not allowed

What does 4505 mean?

The value for the activation of the following error monitoring (velocity) is not allowed, as the value range is limited to [0, 1]. This parameter enables or disables the system's ability to detect deviations between commanded and actual velocity. An invalid setting means critical safety monitoring might be disabled or misconfigured, leading to uncontrolled speeds.

• Parameter Px-01 (velocity following error activation) is set to a value outside the valid range of [0, 1].
• Incorrect firmware version requiring a different parameter range for velocity monitoring activation.
• PLC or HMI is attempting to write an invalid value (e.g., a non-binary number) to the velocity following error parameter.
• Data corruption during parameter write operation, leading to an invalid value being stored in non-volatile memory.

Click steps to track your progress.

1. 1

   Connect to the drive using the commissioning software and read the current value of the velocity following error activation parameter (e.g., P5-01).

2. 2

   Consult the drive's technical manual to confirm the exact parameter number and its allowed range, which is typically [0, 1].

3. 3

   Set the velocity following error activation parameter (e.g., P5-01) to a valid value such as '0' (disabled) or '1' (enabled) based on application requirements.

4. 4

   Save the updated parameter to the drive's non-volatile memory and perform a drive power cycle to apply changes.
