TP Encls Config

What does 28 mean?

This Alarm 2 indicates that Encoderless TorqProve has been enabled, but the specific application concerns, limitations, and risks associated with operating TorqProve without an encoder have not been reviewed or acknowledged. The drive cannot start due to this unaddressed configuration risk. It is crucial to understand these limitations to ensure safe operation.

• P1100 (Torque Prove Mode) is set to an encoderless option (e.g., '1' for Sensorless Torque Prove) without acknowledging risks.
• P35 (Speed Feedback Select) is configured for sensorless vector control (e.g., '0' or 'Sensorless') while TorqProve is active.
• Torque control accuracy requirements for the application exceed the capabilities of encoderless operation.
• Safety function configuration parameter P1101 (Torq Prv Safety Ack) has not been explicitly set to acknowledge encoderless limitations.

Click steps to track your progress.

1. 1

   1. Access the drive HMI or programming software and navigate to P1100 (Torque Prove Mode).

2. 2

   2. If encoderless operation is desired for the application, set P1101 (Torq Prv Safety Ack) to '1' (Acknowledged) to confirm understanding of risks.

3. 3

   3. If an encoder is available and desired for improved accuracy, reconfigure P35 (Speed Feedback Select) to the appropriate encoder input (e.g., '1').

4. 4

   4. Review the application's safety integrity level (SIL) and ensure that encoderless TorqProve meets these specific requirements.

5. 5

   5. Test the TorqProve functionality with a controlled load and monitor actual torque values (e.g., A0-07) to verify proper operation and fault clearance.
