5.2 b: Application
Application parameters configure the source of the frequency reference, the Run command, DC Injection Braking, and
other application-related settings.
u
b1: Mode of Operation
n b1-01: Frequency Reference Selection
Use parameter b1-01 to select the frequency reference source for the REMOTE mode.
Note: 1. If a Run command is input to the drive but the frequency 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.
2. Press the LO/RE key to set the drive to LOCAL and use the operator keypad to enter the frequency reference.
No. Parameter Name Setting Range Default
b1-01 Frequency Reference Selection 0 to 3 1
Setting 0: Operator Keypad
Using this setting, the frequency reference can be input by:
• Switching between the multi-speed references in the d1-  parameters.
• Entering the frequency reference on the operator keypad.
Setting 1: Terminals (Analog Input Terminals)
Using this setting, an analog frequency reference can be entered from terminal A1 using a 0 to 10 Vdc or a 0/4 to 20 mA
signal.
Note: The input signal type must be set up by setting DIP switch S1 and adjusting parameter H3-01. Refer to H3-01: Terminal A1 Signal Level
Selection on page 98 .
Using a 0 to 10 Vdc Voltage Input Signal:
Use a circuit such as the one shown in Figure 5.1 or an external 0 to 10 Vdc voltage source like a PLC analog output and
set the input level selection for A1 in parameter H3-01 as desired. Refer to H3-01: Terminal A1 Signal Level Selection
on page 98 .
Figure 5.1 Setting the Frequency Reference by Voltage Input
Using a 0/4 to 20 mA Current Input Signal:
Connect input A1 to an external current source such as the one shown in Figure 5.2 . Make sure that switch S1 is set to
“I” and set the appropriate signal level by entering 2 (4 to 20 mA) or 3 (0 to 20 mA) into parameter H3-01.
