Description
0: Disabled
1: Enabled
3: PI control enabled (frequency reference + PI output)
Sets P-control proportional gain.
P-control is not performed when the setting is 0.00.
Sets I-control integral time in 1-second units.
I-control is not performed when the setting is 0.0.
Sets the I-control limit as a percentage of the maximum
output frequency.
Sets the limit after PI-control as a percentage of the
maximum output frequency.
Sets the offset after PI-control as a percentage of the
maximum output frequency.
Sets the time constant for low pass filter for PI-control
outputs in 1-second units.
Usually not necessary to set.
Selects forward/reverse direction for PI output.
0: PI output is forward.
1: PI output is reverse
Sets output gain.
0: Limit to 0 when PI output is negative.
1: Reverses when PI output is negative.
Limit to 0 is also active when reverse prohibit is
selected by
b1-04.
0: No detection of PI feedback loss.
1: Detection of PI feedback loss.
Operation continues during detection, the fault con-
tact is not operated.
2: Detection of PI feedback loss.
The motor coasts to stop at detection, and the fault
contact operates.
Sets the PI feedback loss detection level as percentage
using the maximum output frequency as 100%.
Sets the PI feedback loss detection time.
Sets the sleep function start level as a frequency.
Sets the delay time until the sleep function starts.
Sets the accel/decel time for the PI Softstarter (SFS).
