3.5.6 3-9* Digital Pot.Meter

The digital potentiometer function allows the user to increase

or decrease the actual reference by adjusting the set-up of the

digital inputs using the functions INCREASE, DECREASE or

CLEAR. To activate the function, at least one digital input must

be set up to INCREASE or DECREASE.

3-90 Step Size

Range: Function:

0.10 %

[0.01 -

200.00 %]

Enter the increment size required for

INCREASE/DECREASE, as a percentage of

the synchronous motor speed, n

. If

INCREASE/ DECREASE is activated the

resulting reference will be increased /

decreased by the amount set in this

parameter.

3-91 Ramp Time

Range: Function:

1.00 s [0.00 -

3600.00 s]

Enter the ramp time, i.e. the time for adjust-

ment 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

par. 3-95 Ramp Delay the actual reference will

be ramped up / down according to this ramp

time. The ramp time is defined as the time used

to adjust the reference by the step size

specified in par. 3-90 Step Size.

3-92 Power Restore

Option: Function:

[0]

Off Resets the Digital Potentiometer reference to 0% after

power up.

[1] On Restores the most recent Digital Potentiometer

reference at power up.

3-93 Maximum Limit

Range: Function:

100 %

[-200 - 200

Set the maximum permissible value for the

resultant reference. This is advisable if the

Digital Potentiometer is used for fine

tuning of the resulting reference.

3-94 Minimum Limit

Range: Function:

0 %

[-200 - 200

Set the minimum permissible value for the

resultant reference. This is advisable if the

Digital Potentiometer is used for fine tuning

of the resulting reference.

3-95 Ramp Delay

Range: Function:

Application

dependent

[Applica-

tion

dependant]

Enter the delay required from activation

of the digital potentiometer function

until the frequency converter starts to

ramp the reference. With a delay of 0

ms, the reference starts to ramp as soon

as INCREASE / DECREASE is activated.
