Siemens 840D 8036 - Option: it is not allowed to set different IPO cycles or position control

Option: it is not allowed to set different IPO cycles or position control

The option for activating the FAST_IPO_LINK has not been set. For NCU link, all Ipo or position control cycles must then be equal (see FAST-IPO-LINK description).

Safety

  • Refer to Siemens documentation
  • Ensure qualified technician performs repairs

Common Causes

  • FAST_IPO_LINK option not activated in system configuration
  • Mismatched IPO cycle times across multiple NCU channels or drives
  • Position control cycle settings differ between linked axes or channels
  • Missing or incomplete option license for FAST_IPO_LINK functionality
  • Incorrect parameter settings in drive synchronization configuration

Troubleshooting Steps

  1. 1Verify FAST_IPO_LINK option is enabled in the system configuration and machine data parameters; check license status and activate if available
  2. 2Review and compare IPO cycle times across all NCU channels and linked drives; ensure all values are identical
  3. 3Check position control cycle settings for all affected axes; align any mismatched values to match the primary or specified cycle time
  4. 4Examine the NCU link configuration to confirm all slave drives reference the same master cycle time settings
  5. 5Save configuration changes, perform a warm restart (POWER ON/OFF), and verify alarm clears during axis initialization
