Chapter 6 Control Modes of Operation|ASDA-AB Series
Revision January 2009 6-11
For example, the desired position loop responsiveness is equal to 20 Hz.
Then, KPP = 2 × π × 20= 125 rad/s.
Relevant parameters:
P2 - 00
KPP Proportional Position Loop Gain Communication Addr.: 0200H
Default: 35 Related Section:
Applicable Control Mode: P Section 6.2.8
Unit: rad/s
Range: 0 ~ 1023
Settings:
This parameter is used to set the position loop gain. It can increase stiffness, expedite position
loop response and reduce position error. However, if the setting value is over high, it may
generate vibration or noise.
P2 - 02
PFG Position Feed Forward Gain Communication Addr.: 0202H
Default: 5000 Related Section:
Applicable Control Mode: P Section 6.2.8
Unit: 0.0001
Range: 10 ~ 20000
This parameter is used to set the feed forward gain when executing position control command.
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. However, if the setting value is over high, it may generate vibration or
noise.
