Switching between Main/Auxiliary Frequency References
The frequency reference input can be switched between terminal A1 (main) and terminal A2 (auxiliary). When using this
function:
Make sure that b1-01 is set to “1” (Frequency reference from analog input).
Set the terminal A2 function to auxiliary frequency (H3-10 = 2).
Set one digital input to multi-speed 1 (H1- = 3, default for S5).
The frequency reference value is read from
Terminal A1 when the digital input set for multi-speed 1 is open.
Terminal A2 when the digital input set for multi-speed 1 is closed.
Figure 5.2 shows a wiring example for main/auxiliary reference switching using digital input S5.

Setting 2: MEMOBUS/Modbus Communications
This setting requires that the frequency reference is entered via the RS-485/422 serial communications port (control
terminals R+, R-, S+, S-, Protocol: MEMOBUS/Modbus). For instructions, Refer to MEMOBUS/Modbus
Communications on page 351.
Setting 3: Option Card
This setting requires that the frequency reference is entered via an option board plugged into connector CN2 on the drive
control board. Consult the manual supplied with the option board for instructions on integrating the drive with the
communication system.
Note: If the frequency reference source is set for an option PCB (b1-01 = 3) but an option board is not installed in 2CN, an oPE05 Programming
Error will be displayed on the digital operator and the RUN command will not be accepted.
