Parameters — Load and motor
100 Configuration
(CONFIG. MODE)
Value:
✭
Speed control, open loop
(SPEED OPEN LOOP) [0]
Process control, closed loop
(PROCESS CLOSED LOOP) [1]
Function:
This parameter is used for selecting the configuration
to which the frequency converter is to be adapted.
This makes adaptation to a given application simple,
because the parameters that are not used in the given
configuration are covered up (not active). By changing
between the different application configurations,
bumpless transfer (frequency only) is ensured.
Description of choice:
If Speed control, open loop [0] is selected, a normal
speed control (without feedback signal) is obtained,
but with automatic slip compensation, ensuring a
nearly constant speed at varying loads.
Compensations are active, but may be disabled
as required in parameter group 100.
If Process control, closed loop [1] is selected, the
internal process regulator will be activated, thereby
enabling 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.
Parameter 205 Maximum reference and parameter
415 Maximum feedback must be adapted to
the application if [1] is selected.
101 Torque characteristics
(TORQUE CHARACT)
Value:
✭
High-constant torque (H-CONSTANT TORQUE) [1]
High-variable torque high
(H-VAR.TORQ.: HIGH)
[2]
High-variable torque with high starting torque
(H-VT HIGH W. CT-START) [3]
High-special motor characteristics
(H-SPEC.MOTOR CHARACT) [4]
Normal-constant torque
(N-CONSTANT TORQUE)
[5]
Normal-special motor characteristics
(N-SPEC.MOTOR CHARACT) [6]
Normal-variable torque with high constant
starting torque (N-VT HIGH W. CT-START) [7]
Function:
In this parameter, the principle for adjusting the U/f
characteristics of the frequency converter to the
torque characteristics of the load is selected. By
changing between the different torque characteristics,
bumpless transfer (voltage only) is ensured.
Description of choice:
If a high torque characteristic [1]-[4] is selected, the
frequency converter is able to provide 160% torque.
The normal mode is used for oversize motors. Please
note that the torque can be limited in parameter 221.
If Constant torque is selected, a load-dependent U/f
characteristic is obtained in which the output voltage is
increased in the case of an increasing load (current) so
as to maintain constant magnetisation of the motor.
Select High-variable torque with high [3] starting torque
if a higher breakaway torque is required than that
obtainable with the three first-mentioned characteristics.
Select High-constant torque [1] for use with
compressors. Select High-variable torque high [2] for
use with condenser fans or pumps. Use Special motor
mode [3] if several fans are connected in parallel. Use
normal torque characteristics [5]-[7] (110%) to run
with one oversize motor (only 5011 and up).
Choose the torque characteristics giving the most
reliable operation, the lowest possible energy
consumption and the lowest acoustic noise.
Select Special motor characteristics if a special U/f
setting is required to match the motor in question.
Set the break points in parameters 422-432.
NB!:
Slip compensation is not active if a variable
torque or special motor characteristics are used.
