Load and Motor 100-117
This parameter group allows the
con-figuration of regulation param-
eters and the choice of torque char-
acteristics to which the frequency
converter is to be adapted.
The motor nameplate data must be
set and automatic motor adaptation can be carried
out. In addition, DC brake parameters can be set and
the motor thermal protection can be activated.
Configuration
The selection of configuration and torque characteris-
tics influences the parameters that can be seen in the
display. If
Open loop
[0] is selected, all parameters
relating to PID regulation will be hidden.
Consequently, the user is only able to see the param-
eters that are of significance for a given application.

Configuration
(CONFIG. MODE)
Value:
Open loop (OPEN LOOP)
[0]
Closed loop (CLOSED LOOP)
[1]
Function:
This parameter is used for selecting the configuration
to which the frequency converter is to be adapted.
Description of choice:
If
Open loop
[0] is selected, normal speed control is
obtained (without feedback signal), i.e. if the reference
is changed, the motor speed will change.
If
Closed loop
[1] is selected, the internal process reg-
ulator is activated to enable accurate regulation in
relation to a given process signal.
The reference (setpoint) and the process signal (feed-
back) can be set to a process unit as programmed in
parameter 415

Torque characteristics
(VT CHARACT)
Value:
Automatic Energy Optimisation
(AEO FUNCTION)
[0]
Parallel motors (MULTIPLE MOTORS)
[1]
Function:
This parameter allows a choice of whether the fre-
quency converter has one or several motors connec-
ted to it.
Description of choice:
If Automatic Energy Optimisation [0] has been selec-
ted, only one motor may be connected to the frequency
converter. The AEO function ensures that the motor
obtains its maximum efficiency and minimises motor
interference. Parameter 118 makes it possible to set
the power factor (Cos ) which is used by the AEO
function.
Select Parallel motors
[1] if more than one motor is
connected to the output in parallel. See the description
under parameter 108
Start voltage of parallel motors
regarding the setting of parallel motor start voltages.
