Setting 7A, 7B: KEB Ride-Thru 2 (N.C., N.O.)
An input terminal set to 7A or 7B can trigger Single Drive KEB Ride-Thru during deceleration. L2-29 is disregarded if this
is enabled. Refer to KEB Ride-Thru Function on page 241
Digital Input Function
Setting 7A (N.C.)
Setting 7B (N.O.)
Note: Simultaneously assigning KEB Ride-Thru 1 and KEB Ride-Thru 2 to the input terminals will trigger an oPE03 error.
Setting A8: PI2 Disable (N.O.)
Disables the secondary PI controller. Output behavior depends on the setting of S3-12
Setting A9: PI2 Disable (N.C.)
Enables the secondary PI controller (when open, output behavior depends on the setting of S3-12).
Setting AA: PI2 Inverse Operation
Changes the sign of the secondary PI controller input (reverse acting PI control).
Setting AB: PI2 Integral Reset
Resets the secondary PI controller integral value.
Setting AC: PI2 Integral Hold
Locks the value of the secondary PI controller integral value.

If the bias and frequency reference
are constant for 5 s, the bias is
added to the active frequency
reference and reset afterwards.
Not saved
If the bias is constant for 5 s, it is
saved to parameter d4-06. The
frequency reference cannot be
overwritten, so only the bias is
saved.
