When parameter Pb.17 is set as 2, it is used to set the retention pulse threshold for
gain switching.
When parameter Pb.17 is set as 3, it is used to set the speed threshold for gain
switching.
When parameter Pb.17 is set as 4, it is used to set the speed threshold for gain
switching.
When parameter Pb.17 is set as 5, it is used to set the speed threshold for gain
switching.

Gain switching time
constant
ms 0~1000 0 P.T.S
This parameter is used to set the time constant of the transition process when
switching between the 1st gain and 2nd gain. This parameter is active only for the
proportional parameters. By setting this parameter we can lighten the mechanical
shock caused by gain switching. See chapter 7.3 for details.

1st trap wave
frequency
Hz 50~2000 2000 P.S.T
This parameter is used to set the frequency of the 1st trap wave filter for suppressing
resonance. The trap wave filters can simulate the mechanical resonant frequency and
thus suppress the resonant frequency.
50~1999: trap wave frequency;
2000: invalid.

1st trap wave width
selection
dB 1~1000 15 P.S.T
This parameter is used to set the trap wave width of the 1st trap wave filter for
suppressing resonant. A larger trap wave width can be obtained with a larger setting.
