Note: If the starting torque is set too large, the motor may accelerate rapidly. Therefore, please carefully set the starting
torque.

The function to vary speed control proportional gain according to speed command (frequency) during the speed control in vector
control mode (speed sensored 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.
Code No.

nd
When variable 2 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.
nd
When variable 2 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).
nd
Variable 2 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.
Use F6010
as the limiter

Variable by stage
Note: Speed control integral gain has no relationship with this function, it is fixed to be the setting value of F6011.
