Option Name
Description
[2]
PM, salient IPM
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.
[5]
SynRM
Use for SynRM, synchronous reluctance motors.
[6]
PMaSynRM
Use for PMaSynRM, Permanent Magnet assisted synchronous reluctance motors.

Parameter 1-14 Damping Gain
Table 72: Parameter 1-14 Damping Gain
1-14 Damping Gain
Default value: 140%
Parameter type: Range, 0 - 250%
Setup: All setups
Conversion index: 0
Data type: Int16
Change during operation: True
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
Parameter type: Range, 0.01 - 20 s
Setup: All setups
Conversion index: -2
Data type: Uint16
Change during operation: True
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.
