SEW Eurodrive MOVIDRIVE system

This fault indicates issues with the brake output, such as no brake connected, a disconnected brake cable when the brake is commanded 'ON', or an overload condition due to excessive current or frequent operation. This can lead to uncontrolled loads, mechanical damage, or safety hazards if the brake fails to engage or disengage correctly.

The 24V supply voltage for the brake is not within the permitted tolerance of ±10%. This can prevent the brake from operating reliably, potentially causing it to fail to engage or disengage, leading to uncontrolled loads or safety risks. This monitoring is active only when the brake is parameterized as 'installed' and 'applied'.

There is a discrepancy between the raw position data and the track counter of absolute Encoder 1, suggesting an internal inconsistency in position tracking. This can lead to incorrect position readings and unstable drive operation. Unresolved, it can cause erratic movements or positioning errors.

The connected Encoder 1 type is not recognized or supported by the inverter's firmware. This prevents the drive from correctly interpreting encoder signals, leading to non-functional position or speed feedback. Continued operation without proper encoder recognition is impossible.

The drive's current position mode does not allow for movement beyond the configured travel range, indicating a limit has been reached. This prevents further machine movement, potentially causing operational halts if the system attempts to exceed its boundaries. If ignored, it can lead to repeated stops or inability to complete movements.
