Configuration
(CONFIG. MODE)
Value:
Speed control, open loop
(SPEED OPEN LOOP)
[0]
Speed control, closed loop
(SPEED CLOSED LOOP)
[1]
Process control, closed loop
(PROCESS CLOSED LOOP)

Torque control, open loop

Torque control, speed feedback
(TORQUE CONTROL SPEED)
[5]
Function:
This parameter is used for selecting the configuration
to which the adjustable frequency drive is to be adap-
ted. This makes adaptation to a given application sim-
ple, because the parameters that are not used in the
given configuration are covered up (not active). By
changing between the different application configura-
tions, bumpless transfer (frequency only) is ensured.
Description of choice:
IfSpeed control, open loop [0] is selected, a normal
speed control (without feedback signal) is obtained,
but with automatic slip compensation, ensuring a near-
ly constant speed at varying loads.
Compensations are active, but may be disabled as re-
quired in parameter group 100.
IfSpeed control, closed loop [1] is selected, a full hold-
ing torque is obtained at 0 rpm, in addition to increased
speed accuracy. A feedback signal must be provided
and the PID regulator must be set.
IfProcess control, closed loop [3] is selected, the in-
ternal process regulator will be activated, thereby en-
abling accurate control of a process with respect to a
given process signal. The process signal can be set
using the actual process unit or as a percentage. A
feedback signal must be supplied from the process,
and the process setpoint must be adjusted.
IfTorque control, open loop [4] is selected, the speed
is regulated and the torque is kept constant. This is
done without a feedback signal, since VLT 5000 ac-
curately calculates the torque on the basis of the cur-
rent measurement.
IfTorque control, speed feedback [5] is selected, an
encoder speed feedback signal must be connected to
the digital terminals 32/33.
Parameter 205
Maximum reference
and parameter 415
Maximum feedback
must be adapted to the application
if [1], [3], [4] or [5] is selected.
