F)
Optimize the « Speed loop Proportional Gain ». The typical value is 5000. Two methods
allow the setting of this gain.
D
F1)
Method without the « Scope function »
Vary the « Speed loop Proportional Gain » around the typical value. The motor
whistle and oscillate when the gain is too high. In this case, decrease the gain to
obtain a good behaviour (stability) in the whole speed range.
Store this optimal gain by striking F2.
D
F2)
Method with the « scope function »
The respond at a single speed step command looks as follows (with free running
motor) :
Store the optimal gain by striking F2.
D
G)
Optimize the « speed loop Integral Gain ».
The typical value is 50.
Two methods allow the setting of this gain.
