MENU STRUCTURE

To access the monitoring parameters, press the wheel 

on the face of the frequency drive. Using the wheel, 

scroll through the list until the display shows Non (Mon) 

for monitoring mode. This gives the user access to all the 

monitoring parameters.

To access the complete set of drive parameters first 

press the wheel to access different modes. Using the 

wheel, scroll to "COnF" and press the wheel again; this 

will access different sets of parameters. Using the wheel, 

scroll to "FULL" and press the wheel; this will give the user 

access to the complete parameter set.

NAME/DESCRIPTION

UNIT

LFr

External Reference Value: 

External keypad or local force mode configured. Forced local reference FLOC set to LCC and forced local 

assignment FLO different to nO. Displays the speed reference coming from the remote keypad. This value is not 

visible in factory setting.

Hz

rFr

Output Frequency: 

This function provides the estimated motor speed. It corresponds to the estimated motor frequency (on the motor 

shaft). In standard law the output frequency rFr is equal to stator frequency. In performance law the output 

frequency rFr motor speed is equal to the estimated motor speed. 

Range: -400 to 400 Hz

Hz

LCr

Motor Current: 

Estimation of the effective motor current from phase current measurements with an accuracy of 5%. During DC 

injection, the current displayed is the maximum value of current injected in the motor.

A

ULn

Main Voltage: 

Line voltage from the point of view of the DC bus, motor running or stopped.
