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. Refer
to Multi-Step Speed Selection on page 106 for details on using this function.
Setting 2: BACnet or MEMOBUS/Modbus Communications
This setting requires entering the frequency reference via the RS-485 serial communications port (control terminals TXRX+
and TXRX-). Refer to MEMOBUS/Modbus Configuration on page 306 for instructions.
Setting 3: Option Card
This setting requires entering the frequency reference via an option board plugged into connector CN5 on the bypass control
board. Consult the option card manual for instructions on integrating the drive with the communication system.
n Z1-08: Run Command Select
Determines the source of the Auto Mode RUN command used by the Bypass Controller.
No. Name Setting Range Default
Z1-08 Run Command Select 0 to 3 1
Setting 0: HOA Keypad
Setting 1: Bypass Controller Digital Input
This setting requires entering the Run command via the digital input terminals.
Setting 2: BACnet or MEMOBUS/Modbus Communications
This setting requires entering the Run command via serial communications by connecting the RS-485 serial communication
cable to control terminals TXRX+ and TXRX- on the terminal block. Refer to MEMOBUS/Modbus Configuration on page
306 for instructions.
Setting 3: Option Card
This setting requires entering the Run command via the communication option board by plugging a communication option
board into the CN5 port on the control PCB. Refer to the option card manual for instructions on integrating the bypass into
the communication system.
