i950 ES: Expansion of configurable error response for external load encoder

Function Extension:

Safety firmware version V01.05.00.12760 introduced the configurable error response for faults on the external load encoder. With this firmware, additional settings were added (0x287A:013, 0x287A:014) to increase the machine’s uptime in the event of a fault. 

Included in the following products:

 i950 Extended Safety, starting with Safety Firmware V02.00.01.13212

Application:

If a corrupted actual position signal is detected:

  • parameter 0x287A:013 "Position Status Monitoring" determines how the monitored actual position should be handled 
    • Without extrapolation [0]
    • With extrapolation [1]
  • Parameter 0x287A:014 "Filter Time Frozen" is used to detect a frozen encoder position. 
    • min. 0 ms
    • Max. 2000 ms
    • Default 10 ms
    • The position is detected as frozen if the load encoder position remains unchanged for at least this duration while the motor encoder is moving in one direction. A value of 0 disables "monitoring with extrapolation," and the behavior corresponds to Safety Firmware Version V01.04.
