Motor Data - Danfoss VLT FC 102 Programming Manual

Programming Guide | VLT® HVAC Drive FC 102
The damping gain stabilizes the PM machine to 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.
1-15 Low Speed Filter Time Const.
Default value: Size related
Setup:
All setups
Data type: Uint16
The time constant is used below 10% rated speed. Obtain quick control through a short dampening time constant. However, if this value
is too short, the control becomes unstable.
1-16 High Speed Filter Time Const.
Default value:
Size related
Setup: All setups
Data type:
Uint16
The time constant is used above 10% rated speed. Obtain quick control through a short dampening time constant. However, if this value
is too short, the control becomes unstable.
1-17 Voltage Filter Time Const.
Default value:
Size related
Setup: All setups
Data type: Uint16
Reduces the influence of high 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.
