Figure 4.3.108 Speed control architecture (SLV mode )
(c)SV control mode and PMSV mode:
. Speed control system (ASR) tunes the output frequency, to make the frequency
reference and the feedback speed close to 0.
. ASR integrator output can be removed or restricted. All outputs are through the
low-pass filter. The torque will also be limited.

A. The ASR setting of V/F +PG control mode
(1) In V/F+PG mode, set the proportional (P) gain and integral (I) time at the minimum
output frequency (20-02 and 20-03) and maximum output frequency（20-00 and
20-01）. Refer to the figure 4.3.110.
