1.2 b: Application
Application parameters configure the source of the frequency reference, the Run command,
DC Injection Braking, Speed Search, various timer functions, PID control, the Dwell
function, Energy Savings and a variety of other application-related settings.
◆ b1: Mode of Operation
■ b1-01: Frequency Reference Selection 1
Use parameter b1-01 to select the frequency reference source 1 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.
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 signal.
• Terminal A2 using either a 0 to 10 Vdc or a 0/4 to 20 mA signal.
Note: Terminal A2 supports both, voltage and current input. The input signal type must be set up by
setting DIP switch S1 and adjusting parameter H3-09. Refer to the basic instruction manual for
details on setting up DIP switch S1 and to H3-09: Terminal A2 Signal Level Selection on
page 176
Entering only the main frequency reference:
• Using Control Circuit Terminal A1 (0 to 10 Vdc voltage input)
Use a circuit such as the one shown in Figure 1.3 or an external 0 to 10 Vdc voltage
source like a PLC analog output and set the input level selection for A1 in parameter
H3-02 as desired. Refer to H3-02: Terminal A1 Function Selection on page 173.
