Application Configuration; Setting Of Parameters - Danfoss VLT 5000 Series Operating Instructions Manual

Application configuration

Using this parameter enables the choice of a
configuration (setting) of the frequency converter
that fits the application in which the frequency
converter is to be active.
NB!:
First, the motor nameplate date must be
set in parameters 102-106.

There is a choice of the following configurations:
- Speed control, open loop
- Speed control, closed loop
- Process control, closed loop
- Torque control, open loop
- Torque control, speed feedback
The selection of special motor characteristics can be
combined with any application configuration.

is operating) from motor or unit.
Set the following parameters in order shown:
Setting:
Speed control, open loop
Only if [0] or [2] in par. 200
Only if [0] in par. 203
Speed control, open loop is not sufficient or a
full holding torque is required.
