 SMCL parameters
(1) st_cg
st_cg is the proportional gain of control loop in SMCL mode. Normally st_cg must be as large as
possible, but it is on the premise of not affecting the stability of the system. If st_cg is set to be
too large, it may cause vibration and unstable system. At this time, st_cg must be decreased.
st_cg is usually set to 0.2 to 1.5. But if the system is stable enough, st_cg could be more than
1.5.
(2) st_vpg
An initial value is calculated by using the physical parameters set in Motor page in
Configuration center, such as load mass, screw moment of inertia, gear ratio and motor type,
etc. If improper initial value of st_vpg is set, you may use frequency analyzer (Freq analyzer
junior) to do frequency response test to obtain the appropriate value. Normally the st_vpg
obtained from the frequency response test does not need to be adjusted again.
St_cg=0.3, movement 4500 count
St_cg=1.3, movement 450 count
