■ 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,themotornameplatedatemustbe
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 required (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
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
(parameter 346) will be active when parameter 100
is set to Speed control, closed loop.
