Ratio interlock setting
The ratio interlock operation executes the following expression and corresponds to each
speed setting input signal.
Y = AX + B + C
X: Frequency (speed) setting input A: Coefficient (B06-0)
Y: Frequency (speed) command B: Bias (B06-1, 4 where B" = 0)
(operation results) C: Bias (C07-3)

(Ratio interlock bias increase/decrease function)
When IVLM turns ON, is possible to increase/decrease the bias (B”), by BUP and BDW functions.
This bias is added to the ratio interlock bias value (B’)
If BUP turns ON while IVLM is ON, the bias buffer (B") increases its value with the currently valid
acceleration ramp rate. When BDW turns ON, the bias buffer (B") decreases its value with the currently
valid deceleration ramp rate.
If both BUP and BDW turn OFF while IVLM is ON, the current bias buffer value (B") is held.
If IVLM turns OFF, the current bias buffer value(B") is cleared to zero, and the BUP and BDW
operations are ignored.
If the operation command (RUN) turns OFF, the current bias buffer value (B") is cleared to zero. The
BUP and BDW operations are also ignored in this case.
