Function
The function is to make it possible to change the fixed settings of some paramete
rs by means of external analog signals.
1) Acceleration/deceleration base frequency adjustment
If this parameter is so set, The signal from the terminal VI, II or RR can be used as data for the
adjustment of acceleration/deceleration time reference frequencies. This function is useful for
performing proportional operation. Frequency adjustment range: 30 to 400 Hz.

frequency adjustment
2) Upper-limit frequency adjustment
The signal from VI, II or RR can be used as the upper limit frequency.
Adjustment range: 0 (The frequency cannot be set above the upper-limit frequency ().)

3) Acceleration time adjustment
Using reference input from VI, II or RR, acceleration time set with the parameter 
(or acceleration time #2, #3 or #4) can be multiplied the by factors of 1.0 to 10.0 .
10% of reference input act as multiply factor of 1.0 .

4) Deceleration time adjustment
Using reference input from VI, II or RR, deceleration time set with the parameter 
(or deceleration time #2, #3 or #4) can be multiplied the by factors of 1.0 to 10.0 .
10% of reference input act as multiply factor of 1.0 .

5) Manual torque boost adjustment
Using reference input from VI, II or RR, manual torque boost set with the parameter 
(or ,  or ) can be multiplied the by factors of 0.0 to 2.5 .
