8.2 P2x - Fan

The MPA51 controls the fan by

means of PWM signal and evaluates

a hall sensor signal delivered by the

fan in form of a rotation speed.

The number of feedback pulses per

8 Parameters

8.2 P2x Fan

Parameter

P2x

Designation

Description

Setting

P20

Fan: Control

Indicates if the fan is controlled

or regulated. For the regulation, a

feedback signal to record the fan

speed is required!

Setting 0:

Control

Setting 1:

Regulation

P21

Fan: Delay / ramp

a) For fan control:

This parameter is used to smoothen

jumps of the fan activation signal

(PWM signal).

b) For fan regulation:

The desired fan behaviour can be

reached by means of the KP and

TN factors. However, jumps in the

setpoint values for the fan can be

slowed down via the ramp delay

function.

Setting 0 means that even big jumps

are immediately transformed. The

bigger the set value the slower the

PWM signal is adapted to its new

nominal value in case of changes.

The value of the parameter should

be set to 0.

rotations has to be indicated in P24.

In case of wrong values in P24, the

MPA calculates a wrong rotation

speed!

The MPA can control or regulate the

fan (PI controller).
