Parameter Descriptions
The function is activated when one of the following
options is selected: either [10] Danfoss OGD LA10 or [11]
Danfoss OGD V206 in parameter 1-11 Motor Model.
The frequency converter checks if the correct OGD model
is selected. If a wrong OGD model is selected, the
frequency converter performs the following actions:
•
Trips
•
Issues an alarm
•
Sets the parameters defined for the correct model
type
•
Waits for the Reset signal from the operator
The model check takes place every time the frequency
converter gets a start signal from the LCP, a digital input
or a fieldbus.
1-14 Damping Gain
Range: Function:
140 [0 - The damping gain stabilises the PM machine to
% 250 %] run smoothly and with stability. The value of
*
damping gain controls the dynamic performance
of the PM machine. High damping gain gives
high dynamic performance and low damping
gain gives low dynamic performance. The
dynamic performance is related to the machine
data and load type. If the damping gain is too
high or low, the control becomes unstable.

1-17 Voltage filter time const.
Range: Function:
Size [0.001 - 1 Reduces the influence of high
related s] frequency ripple and system

resonance in the calculation of supply
voltage. Without this filter, the ripples
in the currents can distort the
calculated voltage and affect the
stability of the system.
