Invalid parameters of the emergency stop

What does 4226 mean?

The parameters configured for the emergency stop (E-Stop) function are invalid. Specifically, the deceleration or jerk values are set to less than zero, or one of these parameters is weaker (less effective) than the corresponding parameter used for normal start data. Invalid E-Stop parameters compromise machine safety, potentially leading to longer stopping distances or uncontrolled deceleration during an emergency.

Complete Troubleshooting Guide

1. 1

   Review the E-Stop deceleration and jerk parameters in the NC configuration.

2. 2

   Ensure both deceleration and jerk values are positive and physically achievable by the machine.

3. 3

   Verify that E-Stop parameters are set to be more aggressive (stronger) than normal start/stop parameters for safety.

4. 4

   Consult the machine's safety manual for recommended E-Stop parameter values.
