b1-01: Speed Reference Selection
Selects the frequency reference source for the REMOTE mode.
Note: If an Up/Down command is input to the drive but the speed reference entered is 0 or below the minimum frequency, the RUN
indicator LED on the digital operator will light and the STOP indicator will flash.

b1-01
Setting 0: Operator keypad
When b1-01 = 0, the user can enter the speed reference in the following ways:
• Switch between the speed references set to the d1-
multi-function digital input terminal settings. For more detailed instructions, refer to
• Enter the speed reference directly using the digital operator keypad.
Instructions on changing speed reference settings can be found in
Setting 1: Terminals (analog input terminals)
If source of the speed reference is assigned to the control terminals (b1-01 = 1), then d1-18 will automatically be set to 0
so the drive uses multi-speed references d1-01 to d1-08. With this setting, the analog input terminal can be used to set the
speed reference. The drive will look to analog input terminals A1 or A2 for the speed reference (provided parameter H3-
02 or H3-10 must be set to "0", assigning terminal A1 or A2 respectively to the speed reference). Parameter d1-18 is to be
set to 0. Refer to d1: Speed Reference on page 165
Terminals A1 and A2 can accept a voltage signal to supply the speed reference to the drive.

Setting 2: MEMOBUS/Modbus Communications
When b1-01 = 2, the speed reference is given to the drive using MEMOBUS/Modbus register 0002H. Setting the speed
reference from MEMOBUS/Modbus requires setting parameter d1-18 to 0.
Note: Be sure to program the digital inputs for speed selection and set parameter b1-02 to 0 when switching the preset speeds set in the
d1- parameters via MEMOBUS/Modbus. Select the desired speed by switching these digital inputs using the MEMOBUS/
Modbus operation command (0001H).
Setting 3: Option card
When b1-01 = 3, the drive looks to a serial network option card for the speed reference. Setting the speed reference from
a communication option card requires parameter d1-18 to be set to 0.
Note: 1. Be sure to program the digital inputs for speed selection and set parameter b1-01 to 0 when switching the preset speeds set in the d1-
parameters via a communication option card. Select the desired speed by switching these digital inputs using the drive operation
command (refer to the option card manual for details).
2. If the speed 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.
