Parameter 1-14 Damping Gain
Table 72: 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 73: 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.

Description
Use for IPM motors, interior-mounted magnet. PM motors are divided into 2 groups, with either
surface-mounted (SPM)/non-salient magnets or interior-mounted (IPM)/ salient magnets.
Use for SynRM, synchronous reluctance motors.
Use for PMaSynRM, Permanent Magnet assisted synchronous reluctance motors.
Parameter type: Option
