Setting 20 to 2F: External Fault
By using the External Fault function, the drive can be stopped when problems occur with external devices.
To use the external fault function, set one of the multi-function digital inputs to any value between 20 to 2F. The operator
will display EF
† where † is the number of the terminal (terminal S † ) to which the external fault signal is assigned.
For example, if an external fault signal is input to terminal S3, “EF3” will be displayed.
Select the value to be set in H1- †† from a combination of any of the following three conditions:
• Signal input level from peripheral devices (N.O./N.C.)
• External fault detection method
• Operation after external fault detection
The following table shows the relationship between the conditions and the value set to H1- †† :
Setting 30: PID Integral Reset
By configuring one of the digital inputs as an Integral Reset Input, (H1- †† = 30), the value of the integral component of
PID control can be reset to 0 whenever the configured input is closed. The integral component of PID control will be held
at 0 as long as the configured digital input is held closed.
Refer to PID Block Diagram on page 123 for details.
Setting 31: PID Integral Hold
By configuring a digital input for Integral Hold (H1-
††
= 31), the value of the integral component of the PID control is
locked as long as the input is active. The PID controller resumes integral operation from the hold value as soon as the
integral hold input is released.
Refer to PID Block Diagram on page 123 for details.
Setting 34: PID SFS Cancel
A digital input configured as a PID SFS Cancel input (H1- †† = 34) can be used to enable or disable the PID soft starter
and thereby canceling the Accel/Decel time b5-17. Refer to PID Block Diagram on page 123 for details.
Setting 35: PID Input Level Selection
An input programmed for this function can be used to switch the sign of the PID input. Refer to PID Block Diagram on
page 123 for more information on this function.
Setting 40/41: Forward Run/Reverse Run Command for 2-Wire Sequence
Sets the drive for 2-Wire sequence.
When the input set to 40 is closed, the drive operates in the forward direction. When the input set for 41 is closed, the
drive will operate in reverse. Closing both inputs at the same time will result in an external fault.
Setting
<1> Determine the terminal status for each fault, i.e., whether the terminal is normally open or normally closed.
<2> Determine whether detection for each fault should be enabled only during run or always detected.
