6.3 Par. Group 1 - Load and Motor
6.3.1 1-0* General Settings
Dene whether the frequency converter operates in speed
mode or torque mode; and whether the internal PID
control should be active or not. All parameters from
parameter 1-01 Motor Control Principle (included) to
parameter 1-81 Min Speed for Function at Stop [RPM]
(included) are read only. Only parameter 1-13 Compressor
Selection remains accessible for compressor selection.
1-00 Conguration Mode
Option: Function:
NOTICE!
This parameter cannot be adjusted while
the motor is running.
Select the application control principle to be
used when a Remote Reference (via analog
input) is active. A Remote Reference can only be
active when 3-13 Reference Site is set to [0] or
[1].
[0] * Speed
open
loop
Enables speed control (without feedback signal
from motor) to the input signal over the
compressor speed range.
[3] Process Enables the use of process control in the
frequency converter. The process control
parameters are set in parameter groups 7-2*
Process PID Feedback and 7-3* Process PID
Control.
1-13 Compressor Selection
Range: Function:
The default setting of most of the parameters
in the frequency converter (e.g. motor data,
limits, ramps etc.) depends upon the
compressor and system refrigerant selected for
the frequency converter.
The frequency converter selects the default
compressor based upon the power size and
voltage range for the frequency converter.
Under normal circumstances this should not
be changed. During test/repair situations a
dierent compressor can be selected – or if
the system is not using the default refrigerant.
NOTICE!
If the compressor selection is changed,
then all dependent parameters reset to
default and any user settings will be
lost.
Size
dependent.
[] Select the compressor/refrigerant combination
for the system.
