Acceleration of master axis generator is zero

What does E2101 mean?

The IndraDrive MPx02 has detected that the acceleration commanded by the master axis generator is zero. In some motion control scenarios, especially those involving dynamic following, a zero acceleration from the master can indicate an unexpected or incorrect master motion profile, potentially leading to issues for slave axes.

• The master axis generator is providing a constant velocity command with no acceleration, which may be unexpected or inconsistent with the current motion phase.
• An error in the master's motion profile generation, resulting in zero acceleration when acceleration is expected during a profile segment.
• The master axis has completed its acceleration phase and is now at constant velocity, but this warning indicates it's an unexpected state for the slave.
• Incorrect parameterization of acceleration monitoring between master and slave.

Click steps to track your progress.

1. 1

   Review the motion profile or program being executed by the master axis generator to ensure it is correctly generating acceleration commands for the current motion phase.

2. 2

   Verify the parameters related to acceleration and jerk limits in both the master axis and the IndraDrive MPx02 (slave axis) to ensure coordinated operation.

3. 3

   Check if the master axis is operating in a mode that intentionally commands zero acceleration, and if so, confirm that this is acceptable for the application and the slave's reaction.

4. 4

   If the master axis is expected to accelerate, troubleshoot the master controller or motion generator for issues in its profile calculation or command generation.
