0 • When the Up 2 is enabled, the drive accelerates to
the frequency reference plus d4-03 (bias is
increased for d4-03).
• When Down 2 is enabled, the drive decelerates to
the frequency reference minus d4-03 (bias is
decreased for d4-03).
• Holds output frequency (holds the bias) when
neither Up/Down 2 inputs are active or both inputs
are active.
• Resets the bias when the reference changes.
• Operates with the frequency reference in all other
situations.

If the bias and frequency reference
are constant for 5 s, the bias is
added to the active frequency
reference and reset afterwards.

0 • Accelerates (increases the bias) while the Up 2
terminal is closed.
• Decelerates (decreases the bias) while Down 2 is
closed.
• Holds output frequency (holds the bias) when
neither Up/Down 2 inputs are active or both inputs
are active.
• If the frequency reference changes for more than
the time set to d4-07 during accel/decel, bias value
is held until the output frequency meets the
reference (speed agree).

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.

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 240 for details.

Setting 7A (N.C.) Single Drive KEB Ride-Thru 2 Normal operation
Setting 7B (N.O.) Normal operation Single Drive KEB Ride-Thru 2
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.
