Description Full scale
17 Speed limit for forward rotation 0 to maximum output frequency [Hz]
18 Speed limit for reverse rotation
Same as above (same as “17: Speed limit for forward
rotation”)
20 Analog signal input monitor (Same as “3: PID command”)
21 PID feed forward (Same as “3: PID command”)
Gain/Bias
When setting gain and bias, take the maximum frequency required for your application to be 100%.
When setting the bias base point and gain base point data, take full scale of analog input (10 V or 20
mA) to be 100%.
Even if an analog input is unipolar, the frequency setting can be set as bipolar by setting bias as a
negative value. By setting C40 to 10 or 11 at terminal AI2(AII) and setting C45 to 1 at terminal
AI2(AIV), the frequency setting can be set as negative polarity by analog inputs of 0 points or less and
forward/reverse operation can be possible by only analog commands.
Example) When setting the set frequency 0 to 60 Hz by analog input AI1 1 to 5 V (1st Maximum Out-
put Frequency (F03) = 60 Hz)

(A point)
To take the frequency reference to be 0 Hz when the analog input is 1 V, set Input Terminal [AI1, AI2]
Bias for 1st Frequency Command (F18) to 0%. At this time, as 1 V becomes the bias base point and 1
V is equivalent to 10% of full scale 10 V of terminal AI1, set Input Terminal [AI1, AI2] Bias Analog Input
for 1st Frequency Command (C50) to 10%.

o take the frequency reference to be the maximum frequency when the analog input is 5 V, set Input
Terminal [AI1] Gain (Command) (C32) to 100%. At this time, as 5 V becomes the gain base point and
5 V is equivalent to 50% of full scale 10 V of terminal AI1, set Input Terminal [AI1] Gain (Analog Input)
(C34) to 50%.
