■
b1-01: Frequency Reference Source 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 voltage and current input. The input signal type must be set up by setting DIP switch S1 and adjusting
parameter H3-09.
Refer to H3-09: Terminal A2 Signal Level Selection on page 179
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
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

Figure 5.1 Setting the Frequency Reference by Voltage Input
• Using Control Circuit Terminal A2 (0 to 10 Vdc voltage input)
Use the same connection like explained for terminal A1 for terminal A2. Make sure that switch S1 is set to “V” and
set the appropriate signal level for terminal A2 by entering 0 or 1 into parameter H3-09. The terminal A2 function
must be set to frequency bias by entering 0 into parameter H3-10 (
