Switching between Main/Auxiliary Frequency References
The frequency reference input can be switched between the analog terminals A1, A2, and A3 using multi-speed inputs.

for details on using this function.
Setting 2: MEMOBUS/Modbus Communications
This setting requires entering the frequency reference via the RS-485/422 serial communications port (control terminals R+,
R-, S+, S-).
Setting 3: Option card
This setting requires entering the frequency reference via an option board plugged into connector CN5-A on the drive control
board. Consult the option board manual for instructions on integrating the drive with the communication system.
Note:
If the frequency reference source is set for Option PCB (b1-01 = 3), but an option board is not installed, an oPE05 Operator Programming
Error will be displayed on the digital operator and the drive will not run.
Setting 4: Pulse Train Input
This setting requires a pulse train signal to terminal RP to provide the frequency reference. Follow the directions below to
verify that the pulse signal is working properly.
Verifying the Pulse Train is Working Properly
• Set b1-04 to 4 and set H6-01 to 0.
• Set the H6-02 to the pulse train frequency value that equals 100% of the frequency reference.
• Enter a pulse train signal to terminal RP and check for the correct frequency reference on the display.
