• 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.

the time set to d4-07 during accel/decel, bias value
is held until the output frequency meets the

Settings 7A and 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.

Simultaneously assigning KEB Ride-Thru 1 and KEB Ride-Thru 2 to the input terminals will trigger an oPE03 error.
