Causes and Fixes

1
Boot the control into HMI and verify the current startup level by checking machine data MD11210 (STARTUP_MODE_MASK).
2
Access HMI Commissioning mode and navigate to the drive configuration section under 'Startup' -> 'Drives'.
3
Configure all required drives by setting drive type, interface parameters (PROFIBUS/PROFINET address), and assign drives to axes in machine data MD30110 to MD30130.
Incorrect drive configuration can cause physical damage. Verify motor and drive compatibility before proceeding.
4
Complete the startup sequence by executing 'Power On' with complete data save, then perform a full NCK reset (power cycle recommended).
