Incorrect interrupt timing

Was bedeutet F2891 ?

The drive's internal interrupt timing is incorrect. Interrupts are critical for real-time operation and processing, allowing the drive to respond to events promptly. Improper timing can lead to missed events, delayed responses, unstable control loops, and general erratic behavior of the drive's control system.

• Internal hardware fault with the timing circuits
• Firmware error affecting interrupt handler routines
• High CPU load preventing timely interrupt processing
• External interference affecting system clock
• Incorrect system clock configuration

1. 1

   Verify supply voltage stability and ripple on both AC input (L1, L2, L3) and DC bus (DC+, DC-) terminals against the drive's specified operating ranges.

2. 2

   Inspect grounding connections for the IndraDrive MPx02 chassis and the control cabinet, and confirm the integrity of shielding on all connected signal and power cables to mitigate electromagnetic interference (EMI).

3. 3

   Check the currently installed firmware version via the HMI or diagnostic software and compare it to the latest stable release from Bosch Rexroth. Review all critical drive parameters, particularly those affecting control loops, processor load, and synchronization, for correct configuration.

4. 4

   Verify that the ambient temperature and humidity within the control cabinet are consistently maintained within the Bosch Rexroth IndraDrive MPx02's specified environmental operating limits.
