★ = factory setting. ( ) = display text [ ] = value for use in communication via serial communication port

MG.60.B1.02 - VLT is a registered Danfoss trade mark

Description of choice:

The upper signal limit, Ref

HIGH

,of the reference must

be programmed within the normal working range of

the frequency converter, provided parameter 100

Configuration has been programmed for Open loop

[0]. In Closed loop [1] (parameter 100), Ref

HIGH

must

be within the reference range programmed in

parameters 204 and 205.

227 Warning: Low feedback, FB

LOW

(WARN LOW FDBK)

Value:

-999,999.999 - FB

HIGH

(parameter 228)

★ -999.999,999

Function:

If the feedback signal is below the limit, FB

LOW,

programmed in this parameter, the display will show a

flashing FEEDBACK LOW.

The warning functions in parameters 221-228 are not

active during ramp-up after a start command, ramp-

down after a stop command or while stop-ped. The

warning functions are activated when the output

frequency has reached the resulting reference.

The signal outputs can be programmed to generate a

warning signal via terminal 42 or 45 and via the relay

outputs.

In Closed loop, the unit for the feedback is

programmed in parameter 415 Process units.

Description of choice:

Set the required value within the feedback range
