95MG.60.B1.02 - VLT is a registered Danfoss trade mark

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

Programming

224 Warning: High frequency, f

HIGH

(WARN. HIGH FREQ.)

Value:

Par. 200 Output frequency range = 0-120 Hz [0].

parameter 223 - 120 Hz ✭ 120.0 Hz

Par. 200 Output frequency range = 0-1000 Hz [1].

parameter 223 - 1000 Hz ✭ 120.0 Hz

Function:

If the output frequency is above the limit, f

HIGH

programmed in this parameter, the display will show a

flashing FREQUENCY HIGH.

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.

Description of choice:

The higher signal limit of the motor frequency, f

HIGH

must be programmed within the normal working

range of the frequency converter. See drawing at

parameter 221 Warning: Low current, I

LOW

225 Warning: Low reference, REF

LOW

(WARN. LOW REF.)

Value:

-999,999.999 - REF

HIGH

(parameter 226) ★ 0.0 Hz

Function:

When the remote reference lies under the limit,

Ref

LOW

, programmed in this parameter, the display

shows a flashing REFERENCE 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.

The reference limits in parameter 226 Warning: High

reference, Ref

HIGH

, and in parameter 227 Warning:

Low reference, Ref

LOW

, are only active when remote

reference has been selected.

In Open loop mode the unit for the reference is Hz,

while in Closed loop mode the unit is programmed in

parameter 415 Process units.

Description of choice:

The lower signal limit, Ref

LOW

, 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

LOW

must

be within the reference range programmed in

parameters 204 and 205.

226 Warning: High reference, REF

HIGH

(WARN. HIGH REF.)

Value:

REF

Low

(parameter 225) - 999,999.999 ★ 50.0 Hz

Function:

If the resulting reference lies under the limit, Ref

HIGH

programmed in this parameter, the display shows a

flashing REFERENCE HIGH.

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.

The reference limits in parameter 226 Warning: High

reference, Ref

HIGH

, and in parameter 227 Warning:

Low reference, Ref

LOW

, are only active when remote

reference has been selected.

In Open loop the unit for the reference is Hz, while in

Closed loop the unit is programmed in parameter 415

Process units.
