Enter the Maximum

Reference. The Maximum

Reference is the highest

value obtainable by

summing all references.

The Maximum Reference

unit matches:

The choice of

configuration in

H-40 Configuration

Mode: for [1] Speed

closed loop, RPM;

for [2] Torque, Nm.

The unit selected

in F-50 Reference

F-54 Reference Function

Option:

Function:

[0]

*

Sum

Sums both external and preset reference

sources.

[1]

External/Preset Use either the preset or the external

reference source.

Shift between external and preset via a

command or a digital input.

3.3.8 F-6# References

Parameters to configure drive to add or subtract a fixed
value to an input reference.

F-62 Catch up/slow Down Value

Range:

Function:

0 %

*

[0 -

100 %]

Enter a percentage (relative) value to be either

added to or deducted from the actual reference

for Catch up or Slow down respectively. If Catch

up is selected via one of the digital inputs

(E-01 Terminal 18 Digital Input to E-06 Terminal 33

Digital Input), the percentage (relative) value is

added to the total reference. If Slow down is

selected via one of the digital inputs

(E-01 Terminal 18 Digital Input to E-06 Terminal 33

Digital Input), the percentage (relative) value is

deducted from the total reference. Obtain

F-62 Catch up/slow Down Value

Range:

Function:

extended functionality with the DigiPot function.

See parameter group F-9# Digital Pot-Meter.

F-64 Preset Relative Reference

Range:

Function:

0 %

*

[-100 -

100 %]

The actual reference, X, is increased or

decreased with the percentage Y, set in

F-64 Preset Relative Reference. This results in the

actual reference Z. Actual reference (X) is the

sum of the inputs selected in F-01 Frequency

Setting 1, C-30 Frequency Command 2,

C-34 Frequency Command 3 and O-02 Control

Word Source.

F-68 Relative Scaling Reference Resource

Option:

Function:

NOTE

This parameter cannot be adjusted
while the motor is running.

Select a variable value to be added to the

fixed value (defined in F-64 Preset Relative

Reference). The sum of the fixed and

variable values (labelled Y in

Illustration 3.14) is multiplied with the actual

reference (labelled X in Illustration 3.14).

This product is then added to the actual

reference (X+X*Y/100) to give the resultant

actual reference.
