P2 - 03
PFF Smooth Constant of Position Feed Forward Gain Communication Addr.: 0203H
Default: 5 Related Section: N/A
Applicable Control Mode: Pt, Pr
Unit: ms
Range: 2 ~ 100
Settings:
When using position smooth command, increase gain can improve position track deviation.
When not using position smooth command, decrease gain can improve the resonance condition
of mechanical system.
P2 - 04
KVP Proportional Speed Loop Gain Communication Addr.: 0204H
Default: 500 Related Section:
Applicable Control Mode: ALL Section 6.3.6
Unit: rad/s
Range: 0 ~ 20000
Settings:
This parameter is used to set the speed loop gain. When the value of proportional speed loop
gain is increased, it can expedite speed loop response. However, if the setting value is over high,
it may generate vibration or noise.
P2 - 05
SPR Speed Loop Gain Switching Rate Communication Addr.: 0205H
Default: 100 Related Section: N/A
Applicable Control Mode: ALL
Unit: %
Range: 10 ~ 500
Settings:
This parameter is used to set the speed gain switching rate when the gain switching condition is
satisfied. Please refer to P2-27 for gain switching control selection settings and refer to P2-29 for
gain switching condition settings.
