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.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

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

2. 4

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