What does A01699 mean?

The dynamisation timer (r9660) for safety functions has expired, requiring a new dynamisation test. This test verifies the integrity of the safety circuit, and without performing it, the safety functions may not be fully trusted, preventing safe operation and potentially leaving the machine in an unsafe state.

Complete Troubleshooting Guide

  1. 1

    Initiate the dynamisation test by first selecting and then de-selecting the Safe Torque Off (STO) function.

  2. 2

    Ensure that p9601.bit1 and p9801.bit1 are set correctly to enable the STO function for the test, as per the safety manual.
