TeSys T Fallback

Issue:
What is Fallback on the TeSys T and how do the different options operate? 

Product Line:
TeSys T Motor Management Controller

Environment:
Products sold in the North American Market

Cause:
Communications


Resolution:
Fallback mode refers to the state the device goes in to when communication is lost. If communication port loss fault is enabled a fault will occur, otherwise the fallback mode will control the behavior of your device. 

The default option is LO1, LO2 off - this indicates that the outputs used to control the motor will be in the off state any time communication is lost. 
Other options are: 
  • Hold LO1, LO2 - the state of these contacts will remain the same as before the fault occured (on if they were already on, or off if they were off)
  • Run (2-step) or off - the device will follow the local commands issued to either run or be off in 2-step operating modes
  • LO1, LO2 on (ovld, ind, cust) or off - the device will follow the local commands issued to either be on or off in overload, independent, and custom operating modes
  • LO1 on or off (2-step) - the device will follow local commands issued for LO1 to be on or off
  • LO2 on or off (2-step) - the device will follow local commands issued for LO2 to be on or off
