P2.11.2 Follower reference selection ID1081

Select where the follower drive receives its speed reference from.

- Analogue Input 1.

- Analogue Input 2.

Signals \

- Analogue Input 1 + Analogue Input 2.

With alternative reference scaling in Analogue Input group, 100 % input values can be

set to correspond 25 Hz. In other words, when both are 100% the final reference will

be 50 Hz.

Analogue Input 1 minus Analogue Input 2.

Analogue Input 2 minus Analogue Input 1.

Analogue Input 1 x Analogue Input 2

Analogue input 1, -10 Vdc... +10 Vdc

Analogue input 2, -10 Vdc... +10 Vdc

Reference from keypad R3.2

Reference is taken from fieldbus. Alternative scaling can be selected

- Motor potentiometer

Reference handled with two digital inputs \

The smaller of Analogue Input 1 and Analogue Input 2 is used as reference.

The greater of Analogue Input 1 and Analogue Input 2 is used as reference.

Maximum Frequency

P2.1.2 Max Frequency is used as reference.

AI1/AI2 Selection

The digital i

An used to elect

of this parameter is different from 14 (this one).

Reference is read from encoder input 1.

Reference is read from encoder input 2. This selection is usable with double encoder

boards. Could be utilized e.g. for speed synchronization.

17 Master Reference

Master reference before ramp generator. When this is selected the follower drive

own ramp times are active and used.

18 Master Ramp Out

Master reference after ramp generator, before speed controller. When this is

selected the follower drive will use the ramp times defined by the Master drive.
