GEA ARIETE - Application Configuration; Setting of Parameters; Speed Control, Open Loop; Speed Control, Closed Loop (PID)

VLT
®
5000 Series
■ Application configuration
Using this parameter enables the choice of a config-
uration (setting) of the VLT frequency converter that
fits the application in which the VLT frequency con-
verter 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.
■ Setting of parameters
Select Speed control, open loop if a normal speed
adjustment without external feedback signals is re-
quired (the internal slip compensation is operating)
from motor or unit.
Set the following parameters in order shown:
Speed control, open loop:
Parame-
ter:
Setting: Data value:
100 Configuration Speed control, open loop [0]
200 Output frequency range/direction
201 Output frequency low limit Only if [0] or [2] in par. 200
202 Output frequency high limit
203 Reference/feedback range
204 Minimum reference Only if [0] in par. 203
205 Maximum reference
Select Speed control, closed loop if the application
has a feedback signal and the accuracy in Speed
control, open loop is not sufficient or a full holding
torque is required.
Set the following parameters in order shown:
Speed control, closed loop (PID):
Parame-
ter:
Setting: Data value:
100 Configuration Speed control, closed loop [1]
200 Output frequency range/direction Output frequency low limit
