VLT

2800 Series

Programming

NB!:

If the value in par. 144 is increased, the

motor current will simultaneously increase

significantly when generator loads are applied.

The parameter should therefore only be changed if

it is guaranteed during measurement that the motor

current in all operating situations will never exceed the

maximum permitted current in the motor. Please note:

that the current c

annot be read out from the display.

146 Reset voltage vector

(RESET VECTOR)

Value:

*Off (OFF)

[0]

Reset (RESET)

[1]

Function:

When the voltage vector is reset it is set to the same

starting point each time a new process commences.

Description of choice:

Select reset (1) when running unique processes each

time they arise. This will enable repetitive precision

when stopping to be improved. Select Off (0) for

example for lifting/lowering operations or synchronous

motors. It is an advantage that the motor and the

frequency converter are always synchronized.
