7-3 Description of Functions
F6019 Variable 2nd gain for speed control
F6020 Frequency bottom of variable gain for speed control
F6021 Frequency top of variable gain for speed control
The function to vary speed control proportional gain according to speed command (frequency) during the speed control
in vector control mode (speed sensor and speed sensorless). When making a speed control with a large range from low
speed to high speed, different speed control gains are required within low speed zone and high speed zone, at this time
this function can be used.

F6019 Variable 2nd gain for speed control 0: No variable gain function
0.01-150% 0.01% 15
F6020 Frequency bottom of variable gain for
speed control 0-240Hz 0.01Hz 10
F6021 Frequency top of variable gain for speed
control 0-240Hz 0.01Hz 30

When variable 2nd gain for speed control is set to 0, the speed control proportional gain for the whole speed area
is the setting value of speed control ASR proportional gain (F6010) and this value is fixed.

When variable 2nd gain for speed control is not 0, the variable function of speed control proportional gain is
effective.

The speed command at the low speed side of variable speed control proportional gain is set by frequency bottom
of variable gain for speed control (F6020).

The speed command at the high speed side of variable speed control proportional gain is set by frequency top of
variable gain for speed control (F6021).

When speed command (frequency) is smaller than the inner limiter in the speed area of F6020, the speed control
proportional gain will be set by F6010; it will be set by F6019 when the peed command (frequency) is larger than
inner limiter in the speed area of F6021.

When command frequency is within the area of F6020 and F6021, the speed control proportional gain will be
changed according to slope determined by the setting values and frequency range of F6010 and F6019 to the
change linear of speed command (frequency).

Variable 2nd gain for speed control (F6019) can set large or small speed control ASR proportional gain (F6010).

When the setting of frequency top of variable gain for speed control (F6021) is smaller than the setting of
frequency bottom of variable gain for speed control (F6020) (F6020≥F6021), the speed control proportional gain
will be changed by stage with F6020 as the threshold value.

The initial setting of speed control proportional gain function is F6019=15%, F6020=10Hz and F6021=30Hz.
During initial status, the speed control proportional gain function is effective.
Note: Speed control integral gain has no relationship with this function, it is fixed to be the setting value of
F6011.
