Section 9. Reeler calculator

9.1. Turning on and configuration of RC

To activate RC you should set par. 2.9 (for A control) or par 2.10 (for B

control) on „Ref.RC” (fig. 9.2).

CAUTION: RC application works only with vector control (par 1.20 „Vector
1” or „Vector 2”).

CAUTION: Instead of configuring all parameters of Application separately it
is better idea to load factory settings number 9 and then modify only some
parameters. This set is especially intended for Reeler Calculator
Application. Description of loading factory settings can be found in section
3.7.

Table 9.1 – Parameters of reeler calculator

Parameter

Name

Description

5.1

In.V

Source of linear speed signal of rolled medium. Possible values:

Ref.A0, Ref.A1, Ref.A2

– analog referencing-units from analog inputs

5.2

In.F

Source of force referencing-unit signal. It serves for determining of force used to roll medium.
Possible values:

Ref.A0, Ref.A1, Ref.A2

– analog referencing-units from analog inputs

5.3

Vmax

Maximum linear speed of rolled medium. This speed corresponds to 100% of signal value of linear
speed referencing-unit (par. 5.1)

0.00 ... 320.00m/s

5.4

dmin

Minimum diameter of roller (see fig.. 9.1). Basing on this value application determines minimum
torque

0.0 ... 32000mm

5.5

dmax

Maximum diameter of roller (see fig. 9.1). Basing on this value application determines maximum
torque

0.0 ... 32000mm

5.6

Mo

Friction torque set in %

10. Pump Group Controller

The MFC710 built-in control system of pump group (or ventilating fans) enables to control group of maximum 6

pumps (or ventilating fans). Standard frequency converter MFC710 has 4 digital outputs and can serve 4 pumps. The
fifth and sixth pump can be connected using the optional expansion module. One of controlled pumps is the pump with
an adjustable speed of twirl (it is connected to the frequency converter), and other pumps are connected automatically
to work from a mains when needed. Working frequency (pressure) and also quantity of working pumps are adjusted in
feedback using PID controller of the converter or directly from any referencing-unit.

One pump works with a rotational speed which is adjusted by frequency converter MFC710, it is “

the leading

pump

”. Other pumps are switched on/switched off depending on necessity and powered directly from supply grid (these

are

additional pumps

). The frequency converter decides which of pumps is the leading one and also automatically

replaces the leading pump and turns on/shuts down additional pumps.
