D
G1)
Method without the « Scope function »
The « Speed loop Integral Gain » is too low when the axis moves « step by step »
with a small speed command. The motor axis is too smooth.
This gain is too high when the motor axis oscillates with a small speed command.
This gain is optimized when the motor axis doesn’t oscillates and when the
stiffness of the motor axis is sufficient to avoid its motion « step by step ».
D
G2)
Method with the « Scope function »
The respond at a single speed step command looks as follows :
Store the optimal gain by striking F2.
D
H)
The « speed loop Differential Gain » remains in most applications at 0.
