Danfoss VLT 5003 User Manual

Application configuration
Using this parameter enables the choice of a configu-
ration (setting) of the adjustable frequency drive that
fits the application in which the adjustable frequency
drive is to be active.
NOTE
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 ad-
justment without external feedback signals is required
(the internal slip compensation is operating) from mo-
tor or unit.
Set the following parameters in order shown:
Speed control, open loop:
Parameter: 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):
Parameter: Setting: Data value:
100 Configuration Speed control, closed loop [1]
200 Output frequency range/direction Output frequency low limit
201 Output frequency low limit
202 Output frequency high limit
203 Reference/feedback range
414 Minimum feedback Only if [0] or [2] in par. 200
415 Maximum feedback
204 Minimum reference Only if [0] in par. 203
205 Maximum reference
417 Speed PID proportional gain
418 Speed PID integration time
419 Speed PID differentiation time
420 Speed PID diff. gain limit
421 Speed PID lowpass filter time
Please be aware that the encoder loss function (pa-
rameter 346) will be active when parameter 100 is set
to Speed control, closed loop.
