5.3.2 BAS-03 Operating with Auxiliary References
Frequency references can be configured with various calculated conditions that use the main
frequency reference and an auxiliary frequency reference simultaneously. The main frequency
reference (DRV-06) is used as the operating frequency, while the auxiliary reference is used to
modify and fine-tune the main reference.

None
Auxiliary frequency reference is disabled.
1
V1
Sets the V1 (voltage) terminal at the control terminal block as the source
of auxiliary frequency reference.
3
V2
Sets the V2 (voltage) terminal at the control terminal block as the source
of auxiliary frequency reference (SW2 must be set to “voltage”).
4
I2
Sets the I2 (current) terminal at the control terminal block as the source of
auxiliary frequency reference (SW2 must be set to “current”).
5
Pulse
Sets the TI (pulse) terminal at the control terminal block as the source of
auxiliary frequency reference.
BAS-04
Aux Calc Type
The table below list the available calculated conditions for the main and auxiliary
frequency references. Set the auxiliary reference gain with BAS-05 (Aux Ref Gain) to
configure the auxiliary reference and set the percentage to be reflected when
calculating the main reference. Note that items 4–7 below may result in either plus (+)
or minus (-) references (forward or reverse operation) even when unipolar analog inputs
are used.
