Programming 56
The Ref Sample Hold function cannot be programmed at the same time as the following digital input functions:
• Acc/Dec RampHold
• MOP Increase/Decrease
• TrimCtl Increase/Decrease
Doing so will cause an OPE03 fault to occur.
Cycling the input power will erase the sampled analog reference and the Speed Command will begin again from zero.
Function: External Fault
Setting: 20 through 2F
External Fault functionality can be programmed into the digital inputs of the Drive. The External Fault inputs can be used to
signal to the Drive that other equipment related to the operation of the Drive has experienced problems. If the External Fault
is input to the Drive the digital operator will display:
with the x in EFx and Sx represent the terminal number of the digital input that the fault was received on.
To program an External Fault the value input into the H1-0x parameter will determined by:
• Contact type wired to the terminal (Normally Open or Normally Closed)
• Detection profile (Always Detected or Only Detected while Running)
• Drive operation after fault (Stopping Method or Continue Operation)
The following table shows the programming choices.
