Parameter 1-14 Damping Gain
Table 71: Parameter 1-14 Damping Gain
1-14 Damping Gain
Default value: 140%
Conversion index: 0
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.
Parameter 1-15 Low Speed Filter Time Const.
Table 72: Parameter 1-15 Low Speed Filter Time Const.
1-15 Low Speed Filter Time Const.
Default value: Size related
Conversion index: -2
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.
Parameter 1-16 High Speed Filter Time Const.
Table 73: Parameter 1-16 High Speed Filter Time Const.
1-16 High Speed Filter Time Const.
Default value: Size related
Conversion index: -2
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.
Parameter 1-17 Voltage Filter Time Const.
Table 74: Parameter 1-17 Voltage Filter Time Const.
1-17 Voltage Filter Time Const.
Default value: Size related
Conversion index: -3
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.
