Parameters to configure drive digital pot-meter function.
F-90 Step Size
Range: Function:
0.10 % [0.01 - Enter the increment size required for
*
200 %] INCREASE/DECREASE, as a percentage of
the synchronous motor speed, n
INCREASE/DECREASE is activated the
resulting reference will be increased/
decreased by the amount set in this
parameter.
F-91 Accel/Decel Time
Range: Function:
1 s [0 - Enter the ramp time, i.e. the time for adjustment
*
3600 s] of the reference from 0% to 100% of the
specified digital potentiometer function (Increase,
Decrease or Clear).
If Increase/ Decrease is activated for longer than
the ramp delay period specified in F-95 Accel/
Decel Ramp Delay the actual reference will be
acceled/deceled according to this ramp time. The
ramp time is defined as the time used to adjust
the reference by the step size specified in
F-90 Step Size.

converter starts to ramp the reference. With a delay
of 0 ms, the reference starts to ramp as soon as
INCREASE/ DECREASE is activated. See also
